Should We Chase the Good—or Worry Less About the Bad?

Posted Posted in Jayne's blog

For decades, Cognitive Behavioural Therapy (CBT) has been considered the gold standard for treating depression and anxiety—conditions that will affect around one in five people during their lifetime. CBT has strong evidence behind it and, for many, it reduces distressing symptoms such as low mood, fear, and catastrophic thinking.

Yet there is a growing recognition within scientific circles that CBT does not work for everyone. Research shows that only about half of patients benefit, and only half of those experience lasting improvement. Crucially, while CBT often helps reduce negative emotions, it does not reliably restore positive ones—such as happiness, excitement, or a sense of aliveness.

Psychologists had always assumed that by reducing negative emotions—anger, fear, anxiety, sadness—the natural consequence would be for positive emotions to rise on their own. But…they don’t.. not reliably.

This insight has prompted a quiet but profound shift in therapeutic thinking.

Turning Therapy on Its Head

Rather than focusing primarily on correcting distorted thoughts or dampening distress, researchers like Michelle Craske at the University of California, Los Angeles are exploring therapies that actively cultivate positive emotional states—even when those states are fleeting, subtle, or initially uncomfortable.

These approaches borrow tools from CBT but reorient the goal: not merely reducing suffering, butstrengthening the nervous system’s capacity for pleasure, connection, and reward. Large-scale clinical trials in the U.S. and U.K. suggest this shift may be especially powerful for people who experience anhedonia—the blunting or loss of positive emotion that often accompanies depression and anxiety.

One of the most researched of these approaches is Positive Affect Treatment (PAT), developed by Craske and Alicia Meuret of Southern Methodist University. PAT has now been tested in multiple National Institutes of Health–funded trials, comparing it with a CBT-style approach called Negative Affect Treatment (NAT).

Participants in these studies all lived with depression and/or anxiety, and many struggled to feel pleasure at all. Results showed that PAT was significantly more effective than NAT for people with moderate to severe symptoms and pronounced anhedonia.

Reawakening the Brain’s Reward System

PAT is grounded in decades of research showing that people who struggle to feel pleasure are more vulnerable to anxiety and depression. Brain imaging studies reveal that, in many of these individuals, neural circuits involved in reward processing are underactive.

Craske and her colleagues focused on strengthening this system through three key stages of reward:

  • Anticipation (wanting)
  • Consumption (enjoying)
  • Learning (remembering and integrating)

In simple terms: learning to look forward to, fully experience, and mentally store positive moments.

Imagine a teenage girl who hears Taylor Swift is coming to town and eagerly offers to clean the house for a month if her parents buy tickets. That’s anticipation. At the concert, she feels euphoric—that’s enjoyment. Later, she realises the cheaper seats were still great, making future concerts feel more accessible. That’s learning.

For someone with depression or anxiety, any one of these steps may be blocked.

From Correcting Thoughts to Savoring Experience

Consider a woman who tells her therapist she used to love having lunch with a friend, but now feels numb during the meal and worse afterward. After a recent lunch, she spirals into self-criticism—convinced she was boring, that her friend left early because of her, and that she’ll eventually be alone.

In traditional CBT, therapy would focus on challenging these beliefs, examining evidence, and calming the body’s fear response.

In PAT, the therapist takes a different route.

The woman is gently asked to identify anything enjoyable about the lunch—however small. Perhaps the aroma of food made her hungry. Perhaps her friend laughed at a story. Perhaps there was a warm hug at the end. She is then guided to linger with these moments, sensing them fully and imagining their return.

This deliberate savouring—combined with practices such as gratitude and generosity—helps retrain the brain to register and retain positive experiences, much like energy healing practices that attune awareness to subtle but life-giving sensations.

Beyond Positivity: A Practical Balance

Another emerging approach, Augmented Depression Therapy (ADepT), overlaps with PAT but goes further. Developed by Barney Dunn at the University of Exeter in England, ADepT works pragmatically with both positive and negative emotions.

Rather than asking whether a thought is “true” (as CBT does), ADepT asks whether it is useful. If someone about to give a talk feels like an imposter, CBT might challenge the belief. ADepT might instead offer a stabilising alternative: “I know enough about this topic, and I will do an okay job.”

Clinical trials show that ADepT outperforms CBT not only in reducing symptoms, but in improving overall well-being. Eighty percent of participants improved, compared with sixty percent in CBT—and more importantly, they were more likely to stay well a year later.

This translates into: choosing to turn toward the positive helps get more people better, and helps them to stay better for longer.

Why Happiness Can Feel Unsafe

One challenge with positivity-focused therapies is that many people are deeply afraid of happiness. Some believe joy is fleeting and will be followed by disaster. Others feel undeserving. Many unconsciously suppress pleasure because it feels unfamiliar or unsafe. People with depression often employ a whole set of behaviours to snuff out the joy because it feels uncomfortable.

Anxiety adds another layer. Many anxious individuals believe that worrying protects them—that expecting the worst prevents emotional devastation. This phenomenon, known as contrast avoidance, causes people to dampen joy before it can fully arise.

To address this, researchers have developed tools like SkillJoy, an experimental phone app created by Lucas LaFreniere and Michelle Newman. The app encourages users to notice and remain with positive feelings—even when discomfort arises. Early trials show it significantly reduces contrast avoidance.

A New Gold Standard?

Other “positive therapies” are emerging, including amplification of positivity treatment (designed to improve social connection) and behavioural activation therapy, which has long been used to treat anhedonia.

Rather than replacing CBT, these approaches may become part of a hybrid future—one that recognises that some people need first to calm fear, while others long most deeply to feel joy, meaning, and vitality again.

As Craske notes, therapy should be tailored. Someone overwhelmed by panic may benefit most from CBT. Someone who feels empty, flat, or disconnected may need help turning gently toward pleasure. For patients, capturing these moments and building on them can be transformative.

As the year closes and a new one opens, perhaps healing is not only about releasing what hurts—but about learning, patiently and courageously, to let the good in.

Do Childhood Relationships Affect Your Adult Attachment Style?

Posted Posted in Jayne's blog

In therapy, healing and trauma work it’s long been known that our earliest relationships affect our later ones. We come into the world screaming and vulnerable—entirely dependent on adult caregivers to keep us safe and teach us how to connect with others. The nature of these earliest relationships influences how we behave towards others and see the world long after we’ve grown—but in more complex and nuanced ways than researchers previously thought, according to the results of a large, decades-long study examining how the quality of children’s interactions with parents and close peers went on to influence their relationships in adulthood.

In particular, early dynamics with mothers predicted future attachment styles for all the primary relationships in participants’ lives, including with their parents, best friends and romantic partners, the study found. It was found that people who felt closer to their mothers and had less conflict with their mothers in childhood tended to feel more secure in all of their relationships in adulthood. This is s a really striking finding because it demonstrates the enduring impact of that first person who is supposed to be there for you.

Early childhood friends also played a strong role in predicting how participants approached their future close friendships—and their romantic connections. Those first friendships at school help us practice give-and-take dynamics. Relationships in adulthood then mirror those dynamics.

The idea that earliest relationships have an outsized impact on our lives was popularized in psychology by Sigmund Freud. British psychiatrist John Bowlby later incorporated some core Freudian elements to create attachment theory, which helps explain variations in how people approach close relationships. Some people are quite comfortable depending on others, opening up to them and using them as a secure base, whereas other people lack that confidence and trust.

Researchers today define attachment styles by where people fall along two dimensions, each shaped by early experiences with caregivers. The first, attachment anxiety, measures your level of confidence in the availability and responsiveness of those you are close to. People high in attachment anxiety might have more intense fears of abandonment or need for reassurance. The second factor, attachment avoidance, involves how comfortable you feel opening up to others and depending on them for support. Those high in avoidance may believe that people cannot be counted on or trusted, so they avoid asking for help or emotional support—even if they need it. A relationship with high attachment anxiety, avoidance or both is defined as more insecure, while a relationship that is low in both attachment anxiety and avoidance is considered to be secure: You feel comfortable and close to the other person, you trust them to be there for you, and you feel supported.

It can be difficult to study exactly how early relationships go on to influence attachment style, though, because people’s retrospective reports of what happened to them in childhood are skewed by memory failings and emotional and cognitive biases. Of the relatively few studies that have examined associations between early caregiving experiences and adult attachment styles, she adds, all have focused almost exclusively on a single early relationship: the maternal one.

To more deeply understand how early relationships with a wider variety of people impact attachment styles, researchers Dugan, Fraley and their colleagues turned to a landmark longitudinal study of 1,364 children and their families from around the U.S. It began when the children were infants and ended when they were 15 years old. Once the young participants were old enough to speak, they were surveyed about the quality of their relationships with their fathers, mothers and best friends. Researchers also surveyed participants’ primary caregivers—who were mostly their mothers—and observed them interacting with their children. That study showed robust evidence that early experiences with caregivers matter for social development.

Between 2018 and 2022, 705 of the original participants, who by then were 26 to 31 years old, agreed to a follow-up study to collect information about their current relationships with their parents, best friends and romantic partners. For those 705 participants, Dugan and her colleagues analysed associations between the quality of early relationships and later attachment styles in adulthood. They found several notable patterns. First, a person’s relationship with their mother tended to set the stage for their later attachment style in general, as well as for their specific approaches to individual relationships with friends, romantic partners and fathers. For instance, people who had more conflict with their mothers, were less close to their mothers or had mothers who were reportedly harsher and showed less warmth during childhood and adolescence tended to feel more insecure in their adult relationships.

The researchers didn’t find many associations between participants’ relationships with their fathers and their future attachment styles—perhaps because most identified their mother as their primary caregiver. This cohort’s first assessment was in 1991, and even though the burden of caregiving still heavily falls on mothers, fathers were even less involved back then, on average. In cases where a father was the primary caregiver, the results might be flipped—but that data was not collected.

Early experiences with close friends, though, were an even stronger predicter than maternal relationships for determining participants’ approach to—specifically—romantic relationships and friendships in adulthood. In general, if you had high-quality friendships and felt connected to your friends in childhood, then you felt more secure in romantic relationships and friendships at age 30. People who enjoyed increasingly close and deepening friendships across childhood and adolescence also showed significant gains in those departments as adults.

The study’s decades-spanning data are uniquely valuable and allowed the authors to show, using sophisticated analyses, how early social experiences affect later adult personality and close interpersonal relationships.  There has been much praise for the new study because it is seen as exceptionally rigorous and methodologically sound. The scientists have been able to provide some of the strongest prospective evidence to date supporting a foundational assumption of attachment theory: that early relational experiences shape how adults relate to others—not just in general but also within specific types of relationships.

Since the participants were still in early adulthood in the most recent analysis, future work could examine whether the same early-life factors continue to be so influential throughout life—and how major life transitions, such as parenthood, bereavement or divorce, might reshape those dynamics. Single-parent families, multigenerational households and same-sex couples could also be studied in future research. Participants in the current study were nearly 80 percent white, so more racial and ethnic diversity is needed to get a truly representative sample.

Dugan also emphasises that the findings do not mean the past inexorably dictates the tone of a person’s relationships in adulthood. You are definitely not doomed! Evidence supports that adult attachment styles can change in response to later life events and can even fluctuate month to month in response to both positive and negative relationship experiences. These findings show attachment styles are malleable. So relax…you can have a not-so-great relationship with your parents and still develop a secure and healthy bond with a close friend or romantic partner in adulthood.

Can Small, Easy Acts of Joy Lead to Big Gains in Happiness?

Posted Posted in Jayne's blog

There is no shortage of programs or practices that promise to increase happiness. People may meditate for 30 minutes every morning, block off full evenings to deeply connect with close friends or commit to a 12-week daily gratitude journaling exercise. Some of these activities, which emerged from the field of positive psychology, can reliably and sustainably boost psychological well-being, a technical term for happiness in life. But let’s be honest. Most people feel too busy, tired or overwhelmed to add on—and then keep up with—new and demanding routines in day-to-day life.

What if finding more happiness did not require a major time commitment or lifestyle overhaul? What if, instead, it could come from simple, brief actions such as texting a genuine “thank you” to a colleague, asking a friend to share something that made them feel proud, looking at the sky’s vastness with wonder, or marveling at the intricate details of a wildflower?

A group of scientists set out to explore this question by investigating whether brief daily activities, or “micro acts,” can affect overall happiness in life. They also investigated how doing happiness-promoting micro acts might ripple outward in ways that enhance mutual care, compassion, and generosity.

This research began as a spin-off from a film called Mission: Joy—Finding Happiness in Troubled Times (see https://missionjoy.org)  in which the 14th Dalai Lama and the late archbishop Desmond Tutu talked about their friendship and offered lessons on creating joy for oneself and others regardless of circumstances. The film’s producer and co-director Peggy Callahan and impact producer Jolene Smith teamed up with psychologists Elissa Epel and Emiliana Simon-Thomas to develop a meaningful way for people to act on the film’s messages.

The result was a free, globally available online resource called the Big Joy Project (see Freebie section below) carrried out from the University of California, Berkeley. People who signed up for this project received a daily email or text that included a link to instructions for a five- to 10-minute micro act, defined as a short, simple activity for building joy. The opening micro act, for example, invited participants to listen to a 42-second audio clip of different people laughing, including the Dalai Lama and Desmond Tutu. It’s a simple, uplifting moment designed to elicit a smile or chuckle. The rest of the activities are delivered each day for seven days and included making a gratitude list, doing something kind, reflecting on a core value, feeling loving kindness (or a state of tenderness and consideration to others), reframing a difficult experience, celebrating another person’s joy, and watching an awe-inspiring video.

People who joined the project also answered several questions along the way. On a scale from “not at all” to “a lot,” they rated how positively and how negatively they felt before starting and after completing each micro act. People could also reflect on their experience doing each micro act in writing both just afterward and during an evening check-in. Most people reported that they found the micro acts easy and appealing to do. Since its launch, more than 112,000 people across more than 215 countries or territories have joined the Big Joy Project and have done more than 450,000 micro acts. These numbers make it the largest-ever community science project on joy in the world.

The research team gradually expanded with collaborators at several institutions, and together the analysed the data. In two recently published articles, the scientists reported that the micro acts add up in meaningful ways. They compared people’s responses to 18 questions presented before starting the Big Joy Project with most of those questions presented again at the end of seven days. Analysing responses from 17,598 people from 169 countries and territories, they found that people reported higher emotional well-being, more positive emotions, lower stress, and even modest improvements in sleep quality and physical health.

It took surprisingly little time and effort for people to feel better. Although many well-being programs span eight weeks or more, the Big Joy project yielded meaningful changes after just one week. And the more of the micro acts people completed, the more their happiness improved.

Importantly, the benefits weren’t limited to those who had more privilege or access to resources and opportunities. People who reported greater levels of social disadvantage, such as increased financial strain, lower educational attainment and lower subjective social status, often noted greater boosts to well-being as well.

The Big Joy Project also increased people’s self-reported prosociality—that is, their innate impulse to help others and connect with communities. People said they felt more inclined to reach out, offer support and attend to the needs of people around them after completing the project. Once again, there was a clear “dose-response” relationship: the more micro acts a person did, the greater their improvement in prosocial tendencies was.

The biggest increases in this impulse were observed among the least expected groups. Men, whose prosociality scores were lower before beginning the project, showed the largest improvement after seven days. Increases were also more pronounced among people who rated themselves lower in socioeconomic status and for those living in Global South countries. These results suggest happiness-promoting micro acts can have a more pronounced effect where they may be needed most.

In a world grappling with loneliness, burnout and ideological division, small reminders of inspiration, kindness and connection can be powerful. When people experience more joy in their lives, they also tend to be more generous with their time and resources. And when people want to give more to one another, everyone benefits.

Certainly, there is still more for scientists to investigate. For example, the work relies on people reporting their own progress and feelings. It would also be interesting to run the study again but with a subgroup of “control” participants who do not complete daily micro acts. However, for the time being, the current  studies do make a compelling case for how modest steps can have remarkable benefits.

Why do such small actions work? The researchers think it’s because they activate the same psychological ingredients as longer, more involved programs: they boost positive emotions, inspire feelings of connection and help people feel more aligned with what brings them meaning and purpose. Indeed, many of these behaviours—practicing gratitude and being more sociable, for instance—have been well studied for years and found to be beneficial to the doer or giver. But the Big Joy Project is special in its simplicity. It’s low key. People who participated in Big Joy also developed a stronger sense of agency—a feeling that they can control their happiness and that they don’t have to wait for good things to happen to feel happy.

Perhaps that’s what makes the project so powerful. People mired in busyness wait impatiently for a promotion, holiday, new car/house/handbag or entertaining event, expecting to finally feel good. But this project teaches a different lesson. Simple, daily micro acts can ratchet up happiness in a more empowering way. Deliberately finding gratitude, offering kindness or giving ourselves moments to experience awe are not passive acts. They are courageous and effective ways of gently steering your own ship, even through stormy times.

Are Mondays Really More Stressful on the Brain and Body?

Posted Posted in Jayne's blog

For decades the term “Monday blues” has been shorthand for the collective groan that greets the start of each workweek. It’s also well documented in medical statistics. Mondays come with higher rates of anxiety,stress and even suicide compared with other days. Studies on the phenomenon across whole countries have found a 19 percent increase in the odds of sudden cardiac death from confirmed heart attacks and other cardiovascular events on Mondays, affecting men and women across age groups.

It now turns out that the effect of Mondays can extend well beyond fleeting fluctuations in mood. Researcher Tarani Chandola at the University of Hong Kong recently discovered that people who report feeling anxious on Mondays show evidence of heightened activity in the body’s stress-response system over months. More surprisingly, this effect persisted among older adults who were no longer in the workforce, suggesting that, for some people, the stress of Mondays is a lifelong burden.

The biological underpinnings of the “Monday effect” have long been unclear, however. Is the stress and anxiety experienced on Monday biologically distinct? And could this be leaving a mark on people’s body even after they stop working?

To answer these questions, Chandola focused on the stress hormone cortisol. The hypothalamus-pituitary-adrenal (HPA) axis, a central stress pathway linking brain and body, manages much of people’s response to stress. When we experience a stressor—whether it’s something psychological, such as a looming deadline, or physical distress, such as a biting cold morning—the brain triggers the release of cortisol. The hormone helps us to manage short-term stress by mobilising energy and sharpening focus. But chronically high levels of cortisol disrupt the brain and bodily systems, increasing the risk of anxiety, depression, cardiovascular disease, diabetes, and obesity and impairing immune function.

Previous research had shown that cortisol levels can be higher on weekdays than weekends, but few studies had directly examined whether Mondays are uniquely stressful at a biological level. To investigate further, Chandola turned to the English Longitudinal Study of Aging (ELSA), which follows more than 10,000 adults aged 50 and older in England.

Chandola focused on a subset of these participants, asking them questions including, “Overall, how anxious did you feel yesterday?” People also reported which day of the week “yesterday” was. To assess the long-term biological toll of stressful days, the study analysed cortisol levels in participants’ hair samples in order to measure cumulative cortisol production over the past two to three months.

Of the 3,511 participants, 281 people reported feeling anxious on a Monday and 1,080 on another day of the week. Some of these volunteers also provided a hair sample, which let Chandola analyse how hair cortisol levels compared between groups. Crucially, the study also considered whether participants were still working or retired to see if the Monday effect was tied to the all-too-real demands of starting the workweek.

The results were striking. Older adults who reported feeling anxious on Mondays had, on average, 23 percent higher levels of cortisol in their hair samples collected up to two months later, compared with those who felt anxious on other days. This association was strongest among those with the highest cortisol levels—a group at particular risk for health problems associated with chronic stress.

In contrast, anxiety reported on other days of the week did not predict higher cortisol levels. And the effect was not limited to those still working; retirees who felt anxious on Mondays also showed elevated cortisol. In other words, the biological impact of Monday anxiety appears to persist even after the regimen of the workweek fades from daily life.

Some of the reason people show elevated cortisol on Mondays is that they feel more anxious on those days than others. But that’s not the whole explanation. The data show that the effect of anxiety on cortisol is magnified on Mondays. In other words, feeling anxious on the first day of the workweek has a much larger effect on the body’s stress hormones than feeling anxious on other days.

Why might Mondays, in particular, exert a powerful effect on the body? One possibility is that the transition from the weekend to the structured demands of the week is inherently stressful, and some people adapt to it better than others. Another is that Mondays present a higher level of uncertainty. Previous research from Becker  has indicated that anticipation and uncertainty represent key drivers of stress and anxiety. For those who don’t adapt to the weekly cycle, the repeated stress of Mondays may accumulate over the course of a lifetime, eventually leading to long-term problems in the body’s ability to regulate the stress system, which in turn can increase the risk of disease.

It is also possible that some people become anxious on Mondays so routinely that it becomes an automatic bodily response, one that persists even when the original trigger (such as a stressful job) is gone. This effect could reflect deeply ingrained habits of mind and body, shaped by decades of routine.

The recent findings indicate that, for some people, Monday blues are not a personal minor inconvenience but a persistent stressor with long-term—perhaps lifelong—detrimental effects on physical and mental health. The increased risk of heart attacks and other health events on Mondays is unlikely to be a random coincidence. Hospitals and clinics may need to plan for a surge in events at the start of the week, especially among older adults.

In addition, interventions aimed at helping people adapt to the start of the week might have long-term health benefits. The brain’s stress response is plastic, meaning that it can change. Practices that support emotion regulation, including meditation, mindfulness, regular physical activity or good sleep hygiene may help recondition the brain’s weekly cycle and attenuate stress-related health risks.

Finally, researchers will need to investigate why some people are resilient to Monday anxiety while others are not. That question could guide future studies and mental health strategies, opening the door to interventions that help people start the week not just with a groan but with greater resilience.

Also, with the shift in our working lives – following Covid – when many now work from home on a Monday, I wonder what that effect will have. Since companies often now ask their workers to be present on Tuesdays and Thursdays, will we in 20 years time have more stress associated with Tuesdays than Mondays? Now there’s food for thought.

Well this is armchair travel with a twist. Cultures from around the world have cultivated well-being in many fascinating ways—and science agrees that they’re effective! Better yet? They won’t cost you a thing.

Self-care goes global!

  1. Spanish siesta

Let’s start with a bit of winter warmth. In Spain and other Mediterranean places, as well as Latin America and some places in Asia, it’s common practice to take an after-lunch nap, called a “siesta” in Spanish. This afternoon nap time is not just for kids—adults do it too! It’s taken so seriously that museums, shops, and churches usually close for a couple of hours, and everything shuts down.

Adult nap time isn’t just a nice treat to indulge in. Researchers have found that, among generally healthy Greeks, those who partake in regular napping had a 37% lower chance of dying from heart disease within a few years of enrolling in the study. So if you have the ability to take a short nap during the day, try it out! As long as it doesn’t mess up your nighttime sleep, it may be a great way to get an extra boost of well-being.

 

  1. Danish “hygge”

I love the cold. I love coming in after a walk feeling like an ice cube and then being welcomed (and defrosted) by my warm kitchen. And I love being able to curl up with a book on long winter nights. I  love hot baths.

But I know that there are many who definitely don’t share my love of freezing weather!

In 2016, Denmark ranked as the happiest nation in the world in the World Happiness Report. Then, Finland became number one for the next three years, with Norway and Sweden never far behind. Did you ever wonder at the fact that the five happiest countries in the world are almost always cold, Nordic countries. How do they do it?

Of course, there are likely many factors involved. These countries often have less income inequality, greater oil wealth, and breathtaking natural landscapes. But I wondered if there were any specific Nordic secrets to happiness and wellness—even during winter.

The Danish believe in hygge (pronounced “hoo-gah”), which loosely translates to “coziness” and sounds to me a lot like ‘hug’! The word originated from an Old Norwegian word meaning “well-being,” and it captures all that is cozy, warm, and enjoyable. Curling up under a soft blanket while holding a warm mug of cocoa is hygge. Chatting with friends and family around a fire is hygge. And simply enjoying the glow of a candle is hygge.

This concept of hygge not only gives practical inspiration for how to enjoy life—oversized scarves and hot drinks —but it also offers a philosophy for how to be with one’s environment instead of fighting against it. No wonder the Danes are happy in winter!

  1. Japanese forest bathing

On the subject of being with the environment, we’ll ‘travel’ now eastwards to Japan, to take a dip in the woods. Not an actual swim, but rather, an immersion in nature called “shinrin-yoku,” loosely translated to “forest bathing.”

Forest bathing is exactly what it sounds like—being immersed in nature. Importantly, it’s not about going camping, hiking, or doing any hardcore exercise in a forest. In fact, it’s not a goal-oriented activity at all. It’s simply being with nature, with your senses open and your body as your guide.

Health researcher Dr. Qing Li and his colleagues have found that forest bathing enhances the immune system and encourages the expression of anti-cancer proteins. They also found that it decreases depression, fatigue, anxiety, and unsurprisingly, heart rate.

To take a forest bath yourself, you don’t need to seek out special destinations. You can simply find a spot of nature, even if it’s just a group of trees or a garden, and walk through the area slowly and aimlessly. Turn off your mobile phone and simply let the forest in through your five senses.

 

  1. Indian laughter yoga

Who doesn’t enjoy a good belly laugh? But have you ever done it on purpose? The idea of (Indian) laughter yoga is that we don’t have to wait for something funny to happen in order to laugh. Instead, laughter can and should be practiced for its own sake.

Laughter yoga is often practiced in groups, where real playfulness and interaction between people can turn practiced laughs into real guffaws. And there seem to be real health benefits, even if the laughter is “fake.”

A recent meta-analysis found that simulated laughter may be even more effective than spontaneous, humorous laughter for improving mood. So why not give it a try—do a belly laugh like no one is watching. Or better yet, get together with others and laugh with them!

  1. South African Ubuntu philosophy

Speaking of being with others, perhaps nothing captures our social human nature better than the South African philosophy of Ubuntu. This term from the Zulu language can be translated as “humanity towards others,” and it’s part of a phrase that means “a person is a person through other people.” This idea has been spread, in part, by Archbishop Desmond Tutu, a South African theologian, and human rights activist.

The word Ubuntu can be translated as ‘humanity towards others,’ and is part of a phrase that means ‘a person is a person through other people.’

Ubuntu is different from the other items here because it’s not just a practice, but rather, a whole humanist philosophy that embraces diversity, compassion, warmth, and dignity for all.

This may be a philosophy we especially need right now, even if living by it might be a lifelong pursuit. We can begin by acknowledging the humanity of all people, being open to learning, and respecting all, even if we’re unfamiliar or in conflict with someone.

  1. Jewish Sabbath

Observing the Sabbath, the seventh day of the week, is a religious tradition in the practice of Judaism. The Shabbat—meaning “rest” or “cessation”—begins on Friday evening and ends on Saturday evening, during which people refrain from work. Instead, they honour the Sabbath with restful activities like meditation, contemplation, and having festive meals with family. This is what Christian cultures traditionally also do (or did) on  the Sunday – the day of rest.

Research has found that Sabbath-keeping is beneficial for physical and mental health. One Jewish writer, Menachem Kaiser, has referred to the Sabbath as “the only authentic form of leisure: the act and fulfillment of doing absolutely nothing productive” and “our best bet to enact lasting communities.” This sounds like a much-needed balm for our modern hurts.

Research has found that Sabbath-keeping is beneficial for physical and mental health. This is unsurprising, given that much research has established the benefits of rest, spirituality, and even simply eating meals together as a family. So even if you’re not religious, you can practice a secular version of Shabbat and let this weekly time out give you the chance to rest and connect with others. And if you manage to turn off your mobile phone for a day too then you’re really doing well!

Whether it’s through the quietness of forest bathing, or the exuberance of laughter yoga, so many wellness practices and philosophies from around the world get back to the basics—feeling connected to our bodies, our minds, and one another. None of the ideas require you to buy a single thing. All of them invite us to be mindful and connected. And that would be my Christmas and New Years wish for this year!

The Surprising Benefits of Gossip

Posted Posted in Jayne's blog

Scientists have studied gossip for decades. That’s not surprising given how ‘normal’ it is in any social group, big or small.

It’s estimated that more than 90 percent of people in workplaces in Western Europe and North Americaindulge in such banter—defined as talking about someone not present. People in modern societies spend about an  hour a day in chin-wagging, one study reports. But investigators are now approaching this element of social life from a new perspective.

In past decades, researchers have focused primarily on the damage wrought by gossiping, and they zeroed in on either the gossip spreader or the target—the person being talked about. But currently they have changed course by looking more at the benefits of gossip and the dynamics of a three-part network that involves a gossiper, a listener and a target. This research is revealing the complex and diverse roles in shaping perceptions of self and others by looking at factors such as basic information, ego enhancement and social segregation within a group.

So what, if anything, can be good about gossip? Whenever someone confides something to you about someone you both know—whether the information is positive, negative or neutral—it brings the two of you closer, creating a social bond. According to one study, it even increases your liking for the spreader of the information. It helps you learn who to trust and who to avoid. It enforces group norms. For example, complaints about a co-worker who regularly leaves their lunch to rot in the fridge get back to them and let them know that doing so is not an office norm.

But gossip is a double-edged sword for each member of this equilateral triangle. Whether that sword aids or causes harm depends on a host of factors, including the relationships among gossiper, listener and target, the motives of each person and the trustworthiness of the imparted info.

The gossiper is the prime mover in this drama. So it’s not surprising that much of the social science research related to gossip has focused on why they do it, what they get out of it and what the attendant dangers are in doing it, if any. In its most benign form gossip creates a sense of connectedness and belonging. On the other hand, if what you’re sharing is injurious to the target, you may feel guilty. You may also feel anxious about repercussions, including retaliation. There’s the further risk that listeners may form unwelcome impressions about you.

Gossipers have been maligned from time immemorial as rumourmongers or talebearers, yet most of what they impart is actually true, research shows. Sociologist Francesca Giardini of the University of Groningen in the Netherlands and her colleagues found this to be the case in a lab experiment in which students played a series of ‘public goods’ games. In this type of game, players benefit from monetary contributions that they make to a common pool as long as people behave altruistically, but individual players can choose instead to maximize their payoff by acting in their own self-interest. In the study, four players had the opportunity to earn up to €21 from the experimenters depending on how the participants played. If they contributed to their private account, they got what they put in plus a share of the group pot. Everyone benefited more if they all contributed to that pot because its holdings were multiplied by 1.5.

Over several games, players recognised the behaviour of the others, and they were offered opportunities to confidentially warn other players about someone who didn’t contribute to the group. The experimenters learned that the biggest contributors were, on average, also more willing to pass on gossip, here defined as information about self-interested players, that was truthful.

Another lab experiment conducted by social psychologist Terence Dores Cruz, then at Free University Amsterdam, showed that the gossiper passed on true information when they had no conflict of interest with the target of the gossip. When they had a rivalry or other conflict with the target, however, they were likelier to pass on things that were self-serving or outright false. Like a villain in a melodrama, a gossiper can take down a rival, for instance, by manipulating people’s impressions of them. To figure out the gossiper’s motives, the research advises listeners, “ask yourself: Who gains?”

However…even being friends with anyone else in the gossip triangle affects the information’s truthfulness. For example, a friend of the target may not pass on something negative. In addition, a gossiper may say something positive—but false—about a friend.

Despite complex motivations, humans on average are quite good at sizing up the intentions of others with whom they interact. They usually know the person and their place in the network. One study shows that the determining factor of how people interpret gossip is whether they believe someone is passing on gossip to help out the listener or to benefit themselves. If they perceive it to be the former, they trust the gossiper more.

Gossip can be vital to those who listen to it. Learning that a colleague could be leaving their job, for example, could motivate a listener to take on challenging, promotion-worthy assignments. For someone new to a group, gossip can be invaluable. In any large organisation, there are always smaller cliques, in-groups and out-groups. If you are LGBTQ+, for example, gossip from your co-workers about company events or decisions that people have supported or opposed can inform your own decisions.

There has been little research on how gossip affects people in minority groups, but at least one study suggests that it can be helpful in certain cases. Between 2015 and 2020 investigators interviewed residents of Riace, a town in southern Italy that has hosted a variety of refugees and migrants more than 20 years. They found that much of the local gossip occurred between people of different ethnic groups and promoted strong community relationships. Race was not a factor in that research. A study done in 2016 using similar methods at a historically white South African university, however, found that gossip about Black employees not present at meetings undermined their work performance and morale.

There is a common assumption that being the target of gossip is a bad thing, but this is not always the case. Psychologist Elena Martinescu, then at the University of Groningen, and her colleagues found that targets of positive gossip experienced positive emotions such as pride, but negative gossip was sometimes beneficial by inspiring efforts to repair problematic behaviour. The good side is that you may become more aware of how you’re perceived by others. You may adjust your behaviour accordingly. But, in line with popular perception, if people are bad-mouthing about you, they can harm your reputation, your career prospects and your own mental health.

Most of the studies examined gossip in the workplace, but the actual research was conducted in the laboratory or online. Cruz has conducted one of the few studies of how gossip functions in real-life situations. He recruited more than 300 people in a community in the Netherlands and asked them to list 15 people with whom they had frequent contact. Four times each day for 10 days, the subjects were prompted to report on any information that someone in their social network told them—or that they told someone—about a third person. In this exchange, people passed on evaluations of many aspects of a target—qualities such as trustworthiness, warmth and competence. Listeners overwhelmingly believed the gossip to be true, and they updated their beliefs about the person being discussed and adjusted their behaviour toward them.

One of the most beneficial results of gossip is that it helps people better understand the behaviour of others. For example, Cruz found, someone might complain about a co-worker who shows up late every day, but if they learn through gossip that the offending colleague is in the middle of a divorce or that this person’s young son has cancer, they are less likely to complain. Perhaps more important, they sympathise with the co-worker who is suffering a crisis and feel motivated to be more helpful to them. Overall, Cruz and his colleagues found in their study that most gossip in real life was neither positive nor negative, just newsy: someone became a grandparent; someone got engaged. To avoid biasing their subjects, the investigators never used the term gossip.

Gossip may have a bad name, but science shows it’s often not a bad thing.

Enjoy the Office Christmas Party!

Unveiling the Mystery of Pain in the Brain

Posted Posted in Jayne's blog

We’ve known for decades that the placebo effect is very real. This is seen in real-life observations and the best double-blinded randomised clinical trials researchers have devised for many diseases and conditions, especially pain. And yet, how and why the placebo effect occurs has remained a mystery. Now, neuroscientists have discovered a key piece of the placebo effect puzzle.

Publishing in Nature, researchers at the University of North Carolina School of Medicine, along with colleagues from Stanford University, discovered a pain control pathway that links the cingulate cortex in the front of the brain, through the pons region of the brainstem, to cerebellum in the back of the brain.

The researchers, led by Greg Scherrer, then showed that certain neurons and synapses along this pathway are highly activated when mice expect pain relief and experience pain relief, even when there is no medication involved.

That neurons in our cerebral cortex communicate with the pons and cerebellum to adjust pain thresholds based on our expectations is completely unexpected – given the previous /current understanding of the pain circuitry – and incredibly exciting. Scherrer’s results open the possibility to activate this pathway through other therapeutic means, such as drugs or neurostimulation methods to treat pain.

Scherrer and colleagues hope this new research provides a new framework for investigating the brain pathways underlying other mind-body interactions and placebo effects beyond the ones involved in pain.

The Placebo Paradox

It is the human experience, in the face of pain, to want to feel better. As a result — and in conjunction with millennia of evolution — our brains can search for ways to help us feel better. It releases chemicals, which can be measured. Positive thinking and even prayer have been shown to benefit some patients. And the placebo effect — feeling better even though there was no “real” treatment — has been documented as a very real phenomenon for decades.

In clinical research, the placebo effect is often seen in what we call the “sham” treatment group. That is, individuals in this group receive a fake pill or intervention that is supposed to be inert; no one in the control group is supposed to see a benefit. Except that the brain is so powerful and individuals so desire to feel better that some experience a marked improvement in their symptoms. Some placebo effects are so strong that individuals are convinced they received a real treatment meant to help them.

In fact, it’s thought that some individuals in the “actual” treatment group also derive benefit from the placebo effect. This is one of the reasons why clinical research of therapeutics is so difficult and demands as many volunteers as possible so scientists can parse the treatment benefit from the sham. One way to help scientists do this is to first understand what precisely is happening in the brain of someone experiencing the placebo effect.

Enter the Scherrer lab

The authors of the Nature paper knew that the scientific community’s understanding of the biological underpinnings of pain relief through placebo analgesia — when the positive expectation of pain relief is sufficient for patients to feel better — came from human brain imaging studies, which showed activity in certain brain regions. But those imaging studies did not have enough precision to show what was actually happening in those brain regions. So Scherrer’s team designed a set of meticulous, complementary, and time-consuming experiments to learn in more detail, with single nerve cell precision, what was happening in those regions.

First, the researchers created an assay (=test) that generates in mice the expectation of pain relief and then very real placebo effect of pain relief. Then the researchers used a series of experimental methods to study the intricacies of the anterior cingulate cortex (ACC), which had been previously associated with the pain placebo effect. While mice were experiencing the effect, the scientists used genetic tagging of neurons in the ACC, imaging of calcium in neurons of freely behaving mice, single-cell RNA sequencing techniques, electrophysiological recordings, and optogenetics — the use of light and fluorescent-tagged genes to manipulate cells.

These experiments helped them see and study the intricate neurobiology of the placebo effect down to the brain circuits, neurons, and synapses throughout the brain.

The scientists found that when mice expected pain relief, the rostral anterior cingulate cortex neurons projected their signals to the pontine nucleus, which had no previously established function in pain or pain relief. And they found that expectation of pain relief boosted signals along this pathway.

There is an abundance of opioid receptors in this pathway, which supports a role in pain modulation. When activity in this pathway was inhibited, the scientists realised that they were disrupting placebo analgesia and decreasing pain thresholds, giving rise to the experience of more pain. And then, in the absence of placebo conditioning, when we this pathway was activated, pain relief was produced/caused.

Lastly, the scientists found that Purkinje cells — a distinct class of large branch-like cells of the cerebellum — showed activity patterns similar to those of the ACC neurons during pain relief expectation. This is apparently cellular-level evidence for the cerebellum’s role in cognitive pain modulation.

In both the medical and para-medical work, it is widely known that we need better ways to treat chronic pain, particularly treatments without harmful side effects and addictive properties. Let’s hope that these newfindings open the door to targeting this novel neural pain pathway to treat people in a different but potentially more effective way.

Neuroscientists Discover Knowingly Taking Placebos Reduces Stress and Anxiety

Posted Posted in Jayne's blog

It is the human experience, in the face of pain, to want to feel better.

As a result – and in conjunction with millennia of evolution – our brains can search for ways to help us feel better. It releases chemicals, which can be measured. Positive thinking and even prayer have been shown to benefit some patients. And the placebo effect — feeling better even though there was no “real” treatment — has been documented as a very real phenomenon for decades.

The placebo effect is thus very real.

Despite the best double-blinded randomised clinical trials researchers have devised for many diseases and conditions the ‘how and why’ the placebo effect occurs has remained quite a mystery.

In fact, it’s thought that some individuals in the “actual” treatment group also derive benefit from the placebo effect. This is one of the reasons why clinical research of therapeutics is so difficult and demands as many volunteers as possible so scientists can separate out the treatment benefit (i.e. what is the real effect of the pharmaceutical pill) from the sham.

New Nondeceptive Research

 A study out of Michigan State University found that nondeceptive placebos, or placebos given with people fully knowing they are placebos, effectively manage stress — even when the placebos are administered remotely.

Researchers recruited volunteers experiencing prolonged stress from the COVID-19 pandemic for a two-week randomised controlled trial. Half of the participants were randomly assigned to a nondeceptive placebo group and the other half to the control group that took no pills.

The participants interacted with a researcher online through four virtual sessions on Zoom. Those in the nondeceptive placebo group received information on the placebo effect and were sent placebo pills in the mail along with and instructions on taking the pills. COVID-related stress, overall stress, anxiety, and depression were assessed at the beginning, middle, and end of the study.

The study, published in Applied Psychology: Health and Well-Being, found that the nondeceptive group showed a significant decrease in stress, anxiety and depression in just two weeks compared to the no-treatment control group.

Participants also reported that the nondeceptive placebos were easy to use, not burdensome and appropriate for the situation. Compared with the control group, participants in the non-deceptive placebo group reported significant reductions from baseline in all primary affective outcomes after 2 weeks.

And now…

Exposure to long-term stress can impair a person’s ability to manage emotions and cause significant mental health problems long-term. It’s exciting to see that an intervention that takes minimal effort can still lead to significant benefits. This minimal burden makes nondeceptive placebos an attractive intervention for those with significant stress, anxiety and depression.

The researchers are particularly hopeful in the ability to remotely administer the nondeceptive placebos by health care providers. It increases scalability potential dramatically. Remotely administered nondeceptive placebos have the potential to help individuals struggling with mental health concerns who otherwise would not have access to traditional mental health services.

Future large-scale studies are needed to determine if non-deceptive placebos can be effective across different prolonged stress situations and for clinical populations.

Babies Smell Sweet but Teenagers Stink: Is Evolution to Blame?

Posted Posted in Jayne's blog

Teenagers have a reputation for smelling, well, just a bit ‘strong’. According to the latest research, that stereotype might be more than standard adult bias against teenagers in general—it could actually be rooted in solid science.

In a study published on 21st March in the journal Communications Chemistry, researchers characterised the chemical makeup of ‘Essence of Teen’ and compared it with the smell composition of infants and toddlers. They found that, from both a qualitative and quantitative standpoint, children’s body odour takes a dramatically smelly turn after the onset of puberty. And there may be a good evolutionary reason for this shift.

Helene Loos, an aroma researcher at the Friedrich-Alexander University of Erlangen-Nuremberg in Germany and senior author of that new research paper, began this research by attempting to pinpoint the cause of that fragrance change. She and her team first collected body odour samples from 18 infants and toddlers and 18 teenaged children. Then they analysed the samples in the lab to determine what scent chemicals were present in each sample. They also combined their findings with a previous survey of 270 families that had indicated that parents found babies’ body odour much more agreeable than that of teenagers.

The researchers discovered pleasant citrusy and soapy-smelling aldehydes in the body odour samples from both age groups. In the underarm sweat of teens, however, Loos and her colleagues found a higher concentration of carboxylic acids—compounds that are associated with sharp, funky scents such as cut grass, cheese and goat musk. This chemical cocktail was much less pronounced in the infants’ samples. Additionally, two naturally occurring steroids with musk-like odours were only found in the teens’ sweat.

The source of these stinky compounds is complex, but it starts with the activity of the sebaceous glands, which secrete sebum, an oily substance that helps protect your skin and keep your hair shiny and hydrated. The glands are active just before birth and then mostly go dormant for years, but they get very active again around puberty.

When the sebaceous glands ‘reactivate’, they encounter all sorts of bacteria and bodily substances—think sweat—that weren’t around during the infant and toddler years. These additional agents help break down sebum into the kind of smelly molecules that make up the characteristic teenage musksmell. Without much sebum, such compounds simply don’t form in high concentrations on a baby’s skin. Instead that sweet, milky scent that parents find very pleasant lingers.

Evolutionarily this makes a lot of sense: baby odour facilitates bonding between parents and children. But that doesn’t last forever. Once children become teens and are no longer as reliant on their parents, becoming smellier to mum and dad can help them foster a degree of independence as they begin to strike out on their own.

However, other scientists caution that the research might be too preliminary to jump to any firm evolutionary conclusions. Bodily smells change over time,  but  it could be that they have no communicative purpose. For example, imagine a “new car smell.” Most people have a positive association with this scent, even though there isn’t any good evolutionary reason for it. New cars are filled with volatile chemicals that don’t smell particularly nice on their own and might even be hazardous in high concentrations. Yet many people learn to perceive this smell as “good” because it represents the exciting, high-status act of buying a new car. This association is so strong that you can purchase air fresheners designed to make your old car smell like you just drove it from the showroom/car dealer.

Similarly, it’s possible that babies aren’t hardwired to smell nice to their parents. Infants certainly don’t consciously control their body odour in order to manipulate adults into feeding and pampering them. Through repeated exposure, however, parents might come to associate their child’s smell with the dopamine rush produced by caring for them. But just because the association is below the level of conscious awareness doesn’t mean parents aren’t evolutionarily predisposed to find baby scents pleasant and teenage scents repellant. There is previous research on stickleback fish (yes, honestly) that has shown that closely related individual sticklebacks dislike one another’s smell once they reach sexual maturity. Scientists hypothesize that this helps the fish avoid inbreeding when it comes time to choose a mate. A similar mechanism may be at play in humans, with infant smells provoking a deep-seated nurturing response in parents that later turns to avoidance once puberty begins. In other words it could be the receptors of the person who’s perceiving the body odour that  have changed.

Looking ahead, the researchers hope to pair their molecular odour data with magnetic resonance imaging scans of parents’ brain as they sniff their children’s body odour to determine whether a specific brain region is activated by the smell. The researchers also hope to identify whether some odour molecules stay consistent over the course of a person’s lifetime, the scent equivalent of an individual’s unique fingerprint.

But for now, they’re happy to be able to pinpoint some of the molecules behind teens’ unique ‘aroma’. You can’t spell adolescent without “scent,” after all….🤣🤣🤣

Lifting the Veil on Human Consciousness via Near-Death Experiences

Posted Posted in Jayne's blog

Near-death experiences (NDE) have been long reported across time and cultures. An astounding 5 to 10 percent of the general population is estimated to have memories of an NDE, including somewhere between 10 and 23 percent of heart attack survivors. A growing number of scholars now accept NDEs as a unique mental state that can offer novel insights into the nature of consciousness. Neuroscientists no longer question anymore the reality of near-death experience: People who report an experience really did experience something.

Those who undergo an NDE also return with a quality from the experience, which very often changes their life.

A handful of researchers, mostly emergency room doctors, began collecting qualitative data about NDEs after the 1975 publication of psychiatrist and physician Raymond A. Moody’s book Life after Life, which detailed patients’ accounts of near-death experiences. Since then, only a few research teams have attempted to empirically investigate the neurobiology of NDEs. But their findings are already challenging long-held beliefs about the dying brain, including that consciousness ceases almost immediately after the heart stops beating. This discovery has important implications for current resuscitation practices. If we understand the mechanisms of death, then this could lead to new ways of saving lives.

Like psychedelic drugs and other means of altering consciousness, NDEs could also serve as probes for revealing fundamental truths about the mind and brain. Such states are disturbances to the system of consciousness and when you disturb a system, you understand better how it works. If we want to understand the nature of experience, we have to take into account what’s happening at the margins of nonordinary states.

Moreover, there are important existential implications, although exactly what those might be continues to be debated in the scientific literature and at conferences, including at a 2023 meeting held by the New York Academy of Sciences. It explored consciousness through the lens of death, psychedelics and mysticism. Since these transcendent experiences are found in the major world religions and traditions scientists are curious as to if they have some greater purpose for helping humanity cultivate understanding and awareness of consciousness. The weightiness of threse sort of questions makes careful study of NDEs and their rigorous interpretation all the more critical, in order to disentangle empirical findings from beliefs.

Many people who had an NDE describe one or more of a specific set of characteristics. They may recall separating from their body and viewing it in real time from above. They may pass through tunnels and see light, encounter deceased relatives or compassionate entities, and have a sense of vastness and deep insight. People may undergo a life review and morally evaluate the choices they have made, including by experiencing the joy or pain their actions caused others. What’s intriguing is that when people die, they don’t evaluate themselves based on their own standards of morals, they evaluate themselves based on a universal standard.

Although most people describe their NDE in glowing terms, a minority recount visits to hell-like regions, encounters with demonic beings or terrifying voids. In a 2019 study, Charlotte Martial, a neuroscientist at the University of Liège in Belgium and her colleagues found that among 123 people who reported an NDE, 14 percent classified it as negative—a proportion Martial says she’s “sure” is an underestimate because of how disturbing these memories can be.

Somewhat surprisingly, religious people don’t seem to be more inclined toward NDEs. There is, however, preliminary evidence of another group being more likely to have NDEs: those who are prone to REM sleep intrusion, a condition that occurs when rapid eye movement (REM) sleep intrudes into wakefulness and blends elements of dreaming and waking. During the seconds or minutes it lasts for, people may have an out-of-body experience, sense that someone or something is in the room with them, or want to move but find that they can’t. In 2019 Daniel Kondziella, a neurologist at the Copenhagen University Hospital and his colleagues recruited a sample of 1,034 adults from the general population in 35 countries. Ten percent of the study participants had experienced an NDE, and of those, 47 percent also reported REM sleep intrusion—a statistically significant association. Among the people who had not had NDEs, just 14 percent reported REM sleep intrusion.

Still, little is known about the neurobiology of NDEs. Open questions include whether they are driven by a single, core mechanism or are a more variable response to understanding somehow that death is near. A few researchers, including Martial, are peering into the brains of people who are approaching or undergoing death, in the hope of understanding what is going on.

In 2023 Jimo Borjigin of the University of Michigan Medical School and her colleagues published what they suspect could be a signature of NDEs in the dying brain. The researchers analysed EEG data from four comatose patients before and after their ventilators were removed. As their brains became deprived of oxygen, two of the dying patients exhibited a paradoxical surge of gamma activity, a type of high-frequency brain wave linked to the formation of memory and the integration of information.

Borjigin had seen the same upwelling of activity in previous studies of the brains of healthy rats during induced cardiac arrest. In the rodents, the surge occurred across the entire brain. In humans, though, it was confined primarily to the junction of the brain’s temporal, parietal and occipital lobes, a region involved in multiple features of consciousness, including visual, auditory and motion processing. Past research has also associated the region with out-of-body sensations, as well as with altruism and empathy. Although these are all regular components of NDEs, Borjigin says, it’s impossible to know whether the two patients actually experienced an NDE because they did not live to tell about it.

A 2023 study led by Sam Parnia, director of critical care and resuscitation research at the N.Y.U. Grossman School of Medicine and detailed in his forthcoming 2024 book, Lucid Dying, provides further evidence of brain activity after patients’ hearts have stopped. Parnia and his colleagues worked with 25 hospitals in the U.S., the U.K. and Bulgaria to review EEG and brain-oxygen data from 567 people who experienced an in-hospital cardiac arrest. Medical staff managed to collect interpretable EEG data from 53 of these patients. Most showed an electrical flatline during the crisis, but in around 40 percent of those cases, neurological activity consistent with that of conscious brains transiently reemerged—in some instances up to an hour into CPR.

A different subset of 53 patients from the study survived. Doctors collected EEG and brain-oxygen levels for too few of these people to draw a correlation between any potential memory they had of the event and their brain activity. The authors were able to interview 28 of the survivors, and six had a NDE.

Parnia and his colleagues also sought to test conscious and unconscious awareness, including reports of out-of-body experiences, by projecting a series of 10 random images on a tablet placed near patients’ heads and by playing a repeated recording of the names of three fruits—apple, pear, banana—to them through headphones every minute for five minutes while they were unconscious. None of the survivors could remember the images that had been projected. One person who had a recalled experience of death correctly named the fruits in order, although this could have been by chance, Parnia says.

According to Parnia, this study presents a coherent, mechanistic explanation for how and why people have recalled experiences of death. When someone starts dying, Parnia says, the brain becomes dysfunctional. Some actions are immediately lost, such as brain stem reflexes, but others that are normally suppressed to optimise performance for ordinary life suddenly become disinhibited because the brain’s natural braking systems are no longer working. As a result, your entire consciousness comes to the fore. The purpose of this change, he suggests, is to prepare the person “for a new reality”—the transition from life to death, a condition in which, Parnia believes, consciousness endures.

Other scientists flatly disagree. Kondziella suggests that when you have an NDE, you must have a functioning brain to store the memory. And you have to survive with an intact brain so you can retrieve that memory and be able to tell about it. A functioningg brain is necessary for that, so “all those arguments that NDEs prove that there’s consciousness outside the brain are simply nonsense”.

Kondziella, Martial, and others instead theorise that NDEs might be part of a last-ditch survival tactic. Species across the animal kingdom “play dead”—a behaviour technically called thanatosis—when they perceive a mortal threat, typically from an attacking predator. If fight-or-flight fails, the instinct to feign death kicks in as an attempt to forestall the danger. The animal becomes immobilised and unresponsive to external stimuli—but with continued awareness so that, given a chance, it can escape. Kondziella believes the evolutionary aspect really is the key to understanding what NDEs are and how they came about. For him there is a perfectly valid biological explanation.

In their latest study, Martial and her colleagues plan to use the most rigorous approach to date to collect both subjective and objective data from around 100 patients, including EEG and brain-oxygen readings, plus information from several rounds of interviews and surveys with survivors in the group. The University of Liège team is also trying to more thoroughly evaluate claims about out-of-body experiences. Around 79 percent of people who have an NDE report leaving their body, and some wake up knowing facts about their environment that they seemingly should not know. That’s something she wants to test objectively.

To this end, she and her colleagues have decorated the hospital resuscitation room with unexpected objects and images, some of which are hidden in places that could be viewed only from the vantage point of someone near the ceiling. While a patient is in the resuscitation room, including while they are conscious, the team plays an audio clip of various words and animal sounds once every minute. They will test for recollections of any images or sounds in follow-ups with surviving participants, and they will also use video recordings to compare people’s memories with reality.

An easier approach to studying NDEs is via safe proxies such as hypnosis, induced fainting and psychedelic drugs. None of these methods produce true NDEs, but the states they trigger may have some overlap with the dying brain. In 2018 Timmermann, Martial and their colleagues published a study comparing NDEs with the effects of N,N-dimethyltryptamine (DMT), a mind-altering component of ayahuasca, a South American plant-derived psychedelic brew. Trace amounts of DMT also occur endogenously in humans. There’s speculation that that’s somehow underlying NDEs.

In the study, 13 volunteers received intravenous DMT in a lab setting and rated their experience on a scale commonly used to measure NDEs, developed by psychiatrist Bruce Greyson in 1983. The researchers compared the DMT group’s scores and subjective accounts with other people’s taken from an NDE database that Martial and her colleagues have been compiling since 2016. (The database includes around 2,000 accounts, accepted from anyone who contacts the Liège team claiming to have had an NDE and then fills out a lengthy questionnaire.)

They found “striking overlap” between the DMT and NDE groups with people in both describing a sense of entering into an unearthly realm, separating from their body, encountering mystical beings and seeing a bright light. People in both groups also reported feelings of peace, unity and joy. There was just one significant difference: those in the NDE group more frequently experienced reaching a border demarcating a point of no return.

Roland Griffiths, a psychiatrist at Johns Hopkins University who pioneered studies of psilocybin and who died last October, reported similar findings with his colleagues in 2022. The authors compared 3,192 people who had undergone an NDE, a psychedelic drug trip or a non-drug-induced mystical experience. The team found remarkably similar long-term outcomes across subjects in all three groups, including a reduced fear of death and lasting positive effects of insights they had gained.

In another study currently undergoing peerreview, Martial, Timmermann and their colleagues interviewed 31 people who had experienced an NDE and had also tried a psychedelic drug—LSD, psilocybin, ayahuasca, DMT or mescaline—to see what they had to say about the similarities and differences between the events. Participants reported stronger sensory effects during their NDE, including the sensation of being disembodied, but stronger visual imagery during their drug trip. They reported feelings of spirituality, connectedness and deeper meaning across both.

In comparisons of these mystical experiences, Bossis has found that the common ground is in things like a profound, deep sense of love—that all is love and that consciousness is love. He studies the effects of psilocybin in people with terminal cancer, focusing on relieving end-of-life distress, enhancing spirituality, and providing a greater sense of meaning and fulfillment in life. There’s also a sense of transcending time and a greater acceptance of the mystery of life and death.

Regardless of how people interpret NDEs, studying them may provide a better understanding of mind and brain, and hopefully further illuminate some of the deepest mysteries of existence.

How Can Nature Help Us Heal Our Frantic Sense of Time?

Posted Posted in Jayne's blog

In an increasingly competitive world, time is of the essence. Notions of productivity and timeliness have accelerated contemporary lifestyles to a dizzying, sometimes overwhelming pace, and our dependence on technology is doing little to help. As the clock grows to dominate the tempo of life, time itself seems to be increasingly fleeting. This is particularly true in large cities, where hours, days, and even weeks can sometimes seem to fly by in an instant.

Indeed, an increasing number of people report constantly feeling short of time. Such feelings of “time scarcity” emerge from how time is both used and perceived by people. Long working hours inevitably limit the time that people have available for other activities, but leading fast-paced lifestyles while packed into noisy, dynamic and crowded urban environments is mentally exhausting, and this can also influence how we perceive time.

In a recent publication, research was published that nature experiences offer a potential solution to the increasingly widespread feelings of time scarcity caused by contemporary urban lifestyles. This emerges from the unique nature of human time perception, which is highly subjective, and moulded by the experiences and environments in which we immerse ourselves.

Human sense of time

Human time perception — our sense of time — is made up of three key dimensions. One of these is temporal succession, meaning the way we perceive the order and overlap of different events. For instance, pressing a light switch and the light turning on may seem like simultaneous events, but we have the capacity to perceive the order in which they happen, and this helps us to make sense of the world around us.

Another dimension is temporal duration, or how we perceive and estimate the duration of an event. An afternoon spent with your accountant, for example, can seem to last forever, while the same amount of time spent in the company of friends can seem short and swift. Popular expressions such as “time stood still” or “time flies when you’re having fun” reflect our perception of temporal duration.

The third dimension is called temporal perspective, and it refers to the way we regard the past, present and future. Humans have a unique capacity to mentally “time travel” and focus on representations of the past, present and future. Most people have a natural tendency towards certain perspectives, either dwelling on the past or focusing on the future, but maintaining a balanced and dynamic time perspective is a sign of psychological wellbeing.

Together, these dimensions help humans make sense of time. However, the way we perceive them can be profoundly influenced by our own characteristics, what goes on around us, and what we do during a given period of time. Our perception of time changes hugely when, for example, work captures our attention, when we are stuck in traffic, or when we find ourselves in the dentist’s chair undergoing a painful procedure.

In contrast, nature experiences can be mentally, physically and emotionally restorative, and this is reflected in our perception of time.

How nature experiences help regulate human time perception

Evidence from psychological experiments suggests that there are at least two ways natural surroundings can have a positive impact on human time perception.

One of these is expanding our perception of temporal duration. For example, one study reports that when people are inquired how long they have been walking in natural or urban settings, they tend to overestimate the time spent strolling in nature, but not in the city. In other words, time feels longer when we are immersed in natural settings in comparison to urban environments. Ha! My experience, exactly!

The other way nature experiences can influence our time perception is by promoting a shift in perspective. In one experiment, participants spent a short period of silence either indoors or outdoors, and were later asked how this experience influenced their temporal orientation towards the past, present and future. People who experienced the natural setting reported feeling more focused on the present, and less on the past.

Other studies have provided similar evidence suggesting nature experiences can help us shift our perspective on time, and induce a more positive outlook of the present moment.

While there is plenty of evidence that nature experiences have various physical and mental benefits, the idea that such experiences can help people uplift their relationship with time is new, and provides a unique perspective on the importance of nature for human well-being.

Is Writing by Hand Better for Memory and Learning?

Posted Posted in Jayne's blog

Handwriting notes in class might seem unnecessary as smartphones and other digital technology take over every aspect of learning across schools and universities. But a steady stream of research continues to suggest that taking notes the traditional way—with pen and paper or even stylus and tablet—is still the best way to learn, especially for young children. And now scientists are finally zeroing in on why.

A recent study in Frontiers in Psychology monitored brain activity in students taking notes and found that those writing by hand had higher levels of electrical activity across a wide range of interconnected brain regions responsible for movement, vision, sensory processing and memory. The findings add to a growing body of evidence that has many experts speaking up about the importance of teaching children to handwrite words and draw pictures.

DIFFERENCES IN BRAIN ACTIVITY

The new research, by Audrey van der Meer and Ruud van der Weel at the Norwegian University of Science and Technology (NTNU), builds on a foundational 2014 study. That work suggested that people taking notes by computer were typing without thinking. It appears to be very tempting to type down everything that the lecturer is saying since it goes in through your ears and comes out through your fingertips. But you apparently don’t process the incoming information. But when taking notes by hand, it’s often impossible to write everything down; students have to actively pay attention to the incoming information and process it—prioritise it, consolidate it and try to relate it to things they’ve learned before. This conscious action of building onto existing knowledge can make it easier to stay engaged and grasp new concepts.

To understand specific brain activity differences during the two note-taking approaches, the NTNU researchers tweaked the 2014 study’s basic setup. They sewed electrodes into a hairnet with 256 sensors that recorded the brain activity of 36 students as they wrote or typed 15 words from the game Pictionary that were displayed on a screen.

When students wrote the words by hand, the sensors picked up widespread connectivity across many brain regions. Typing, however, led to minimal activity, if any, in the same areas. Handwriting activated connection patterns spanning visual regions, regions that receive and process sensory information and the motor cortex. The latter handles body movement and sensorimotor integration, which helps the brain use environmental inputs to inform a person’s next action.

When you are typing, the same simple movement of your fingers is involved in producing every letter, whereas when you’re writing by hand, you immediately feel that the bodily feeling of producing A is entirely different from producing a B. It  seems that children who have learned to read and write by tapping on a digital tablet often have difficulty distinguishing letters that look a lot like each other or that are mirror images of each other, like the b and the p.

REINFORCING MEMORY AND LEARNING PATHWAYS

The findings in the new study are exciting and consistent with past research. With tasks that lock the motor and sensory systems together, such as in handwriting, there is a clear tie between the motor action being accomplished and the visual and conceptual recognition being created. As you’re drawing a letter or writing a word, you’re taking a perceptual understanding of something and using your motor system to create it. That creation is then fed back into the visual system, where it’s processed again—strengthening the connection between an action and the images or words associated with it. It’s similar to imagining something and then creating it: when you materialise something from your imagination (by writing it, drawing it or building it), this reinforces the imagined concept and helps it stick in your memory.

The phenomenon of boosting memory by producing something tangible has been well studied. Previous research has found that when people are asked to write, draw or act out a word that they’re reading, they have to focus more on what they’re doing with the received information. Transferring verbal information to a different form, such as a written format, also involves activating motor programs in the brain to create a specific sequence of hand motions. But handwriting requires more of the brain’s motor programs than typing. When you’re writing the word ‘the,’ the actual movements of the hand relate to the structures of the word to some extent.

For example, participants in a 2021 study by memorised a list of action verbs more accurately if they performed the corresponding action than if they performed an unrelated action or none at all. Drawing information and enacting information is helpful because you have to think about information and you have to produce something that’s meaningful. And by transforming the information, you pave and deepen these interconnections across the brain’s vast neural networks, making it much easier to access that information.

THE IMPORTANCE OF HANDWRITING LESSONS FOR KIDS

Across many contexts, studies have shown that kids appear to learn better when they’re asked to produce letters or other visual items using their fingers and hands in a coordinated way—one that can’t be replicated by clicking a mouse or tapping buttons on a screen or keyboard. Research has also found that the action of handwriting appears to engage different brain regions at different levels than other standard learning experiences, such as reading or observing. Her work has also shown that handwriting improves letter recognition in preschool children, and the effects of learning through writing last longer than other learning experiences that might engage attention at a similar level. Additionally, she thinks it’s possible that engaging the motor system is how children learn how to break “mirror invariance” (registering mirror images as identical) and begin to decipher things such as the difference between the lowercase b and p.

The new study opens up bigger questions about the way we learn, such as how brain region connections change over time and when these connections are most important in learning. These new findings don’t mean technology is a disadvantage in the classroom. Laptops, smartphones and other such devices can be more efficient for writing essays or conducting research and can offer more equitable access to educational resources. Problems occur when people rely on technology too much. People are increasingly delegating thought processes to digital devices, an act called “cognitive offloading”—using smartphones to remember tasks, taking a photo instead of memorising information or depending on a GPS to navigate. Scientists think it’s helpful, but the constant offloading means we’re not actively using those memory or motor areas in  the brain,…that can lead to deterioration over time.

Van der Meer says some officials in Norway are inching toward implementing completely digital schools. She claims first grade teachers there have told her their incoming students barely know how to hold a pencil now—which suggests they weren’t colouring pictures or assembling puzzles in nursery school. Van der Meer says they’re missing out on opportunities that can help stimulate their growing brains. Scientists are discovering that there is a very strong case for engaging children in drawing and handwriting activities, especially in preschool and kindergarten when they’re first learning about letters. Engaging the fine motor system and production activities that impacts learning and is vitally important!
