On the island of Okinawa, Japan, driving about 90 minutes up the coast from the capital Naha lands you in Ogimi. Known as the “longevity village,” it historically has the most centenarians per square mile compared to anywhere else on Earth.
One of the factors that may benefit their health most: consistent and regular social interaction, in the form of tight-knit community networks. I was invited to sit in on one of their formal monthly meetings, arranged by the Japan National Council of Social Welfare.
When I interviewed 90-year-old Fumi Teruya, she explained that every morning she sweeps the deck of her home. In doing that she exercises but also catches up with neighbors around the village who are out for their morning walk. Other friends regularly come over to cook lunch with her, and the evenings are often spent singing or chatting with neighbors, all of which she believes keeps her youthful and happy.
The research agrees: These relationships may boost longevity.
Back in the capital, renowned doctor and longevity researcher Makoto Suzuki, M.D., Ph.D., of the Okinawa Research Center for Longevity Science (ORCLS) has been studying centenarians in Okinawa since 1976. He has found that these networks form a sense of social cohesion that is an important part of why many Okinawans have enjoy a long, and often disease-free, life. These networks are known as moai.
“Moais involve ritualistic connections that are both reliable and close knit, which involve a common interest but not usually a common professional identity,” Suzuki said. “In my own moai, we have 10 members, and I’m the only doctor. A time is decided, a venue is decided, and the rules are decided as well.”
Suzuki’s ORCLS research partner since the last 1990s and co-author of The Okinawa Program Craig Wilcox, Ph.D., MHSc, FGSA, added, “A moai is more than just a friend group. It’s often village-based and consists of rituals and institutions that keep people connected.”
There’s a global problem with loneliness.
It’s no secret that loneliness is an epidemic, and a study published in June reviewed how our general health and wellness can be affected by our social networks, and during the holiday season, isolation is felt more deeply. Loneliness has been linked to heart disease, metabolic syndrome, diabetes, malnutrition, dementia, depression, and mortality. One theory behind this link is that chronic isolation disrupts a number of neuroendocrine factors that lead to higher stress response.
Over the last several years, I’ve personally encountered many patients with the disease of isolation, from discussions about end-of-life care with a patient who had become estranged from his family to a teenage girl who had overdosed and shared that the bullying about her weight had taken a toll. Upon further probing, it became clear that it wasn’t the bullying itself but that she had no one to lean on to help deal with it.
Some health systems are addressing the problem of loneliness. In the U.K., the NHS appointed a chief loneliness officer. Suzuki’s years of research suggest the answer to this epidemic might be intentionally creating our own purpose-centered social networks, in other words, moais.
In 2017, study out of Spain found that social networks, and higher frequency of social interaction, can reduce depression among older adults. Interventions aimed at improving social support among patients with cardiac disease appear promising, as are early reports from studies of seniors in Israel and in Sweden and Canadian men facing retirement. And among parents specifically, building social support systems can decrease postpartum depression and the isolation that comes with being a new parent.
What can be done to help combat loneliness?
However, these studies also face the issue of replicability, and causal associations are difficult to draw. For instance, earlier this month, a study led by Jason Chen, Ph.D., of the Center to Improve Veteran Involvement in Portland, was published in Social Psychiatry and Psychiatric Epidemiology. They found that, counterintuitively, among veterans, loneliness was associated with lower depression severity. This has prompted study authors to more closely examine the role of social support interventions.
“We are currently looking at interventions that are not only relevant to veterans just at our hospital but also in other settings,” Chen said. “In addition, our study team is interested in emphasizing the potential for loneliness interventions for our more rural, isolated populations in Oregon and beyond.”
Reza Ghomi, M.D., is a Seattle-based neuropsychiatrist who sees firsthand how social support alone can have a dramatic impact on emotional well-being.
“Social isolation has dramatic effects not only on mental health such as increasing risks for depression and anxiety, but now we are seeing it can increase risk for cognitive impairment and ultimately dementia,” Ghomi said. “Building community does the reverse and promotes a sense of well-being and satisfaction including improvement in cognitive abilities.”
When it comes to the medical community, at a time when burnout was just named as one of the biggest challenges in health care by a Lancet report, finding supporting environments remains key among health care providers. Dana Correil, M.D., an internist and co-founder of SoMeDocs (“social media doctors”), points to the benefits of her “moai” being centered around a shared interest in advocacy and health care communication.
“For doctors, social media can be a space for connection, a powerful tool to mitigate the loneliness epidemic,” Correil said. “It allows us to exchange ideas, find camaraderie and perspective for issues challenging our profession today and provides us with opportunities to make actual change.”
And the opportunity for doctors to connect offline have flourished: everything from storytelling workshops like the Nocturnists, narrative medicine programs to Schwartz rounds help build community around shared vulnerability.
They say it takes a village to raise a child. But, as the science suggests, the health and well-being of all of us may benefit from having our own village, or moai: at home, work, and everywhere in between.

“So, if we’re worried about viral myocarditis, would the patient have similar symptoms as someone with pericarditis?” The astute medical student slipped me his question as we hurriedly made our way across the ward to the next patient’s room.
He had wondered whether inflammation of the heart muscle (as in myocarditis) presents like inflammation of the protective layer around the heart (the pericardium). Classically we are taught that pericarditis-type chest pain is better when sitting up (because the protective layer is kept away from the nerves that transmit pain) compared with lying down or when taking deep breaths.
“Well there is some overlap in clinical signs,” I began. But we were already on to the next patient, and so my attention was redirected. The student had looked eager to hear my response, but that expression quickly slipped away.
These missed opportunities, to explore and address complex questions, are frequent in medical education, and the downstream consequences of not fostering this curiosity are significant.
Curiosity is the necessary fuel to rethink one’s own biases, and it can reap dividends for patient care. When doctors think about a set of symptoms separately, they may reach different conclusions; for example one study found that up to 21% of second opinions differ from the original diagnosis.
Allowing doctors to express their curiosity is crucial and it’s time we encourage all medical trainees to be curious.
The decline in curiosity could be caused, in part, by medical trainees assuming a traditionally passive role in hierarchically organized settings like hospitals, suggests a 2011 paper, coauthored by Ronald Epstein, MD, a professor of family medicine, psychiatry, oncology and medicine at the University of Rochester Medical Center.
“There’s a dynamic tension here. People pursue medicine because they are curious about the human experience and scientific discovery, but early in training they are taught to place things in categories and to pursue certainty,” Epstein told me.
A 2017 McGill University study led by pediatrician Robert Sternzus, MD, took this theme a step further. Sternzus and colleagues surveyed medical students across all four years about two types of curiosity: trait curiosity, which is an inherent tendency to be curious; and state curiosity, defined as the environment in which the trait curiosity can survive. Trait curiosity across all four years was significantly higher than state curiosity. The authors concluded that the medical students’ natural curiosity may not have been supported in their learning environment.
“I had always felt that curiosity was strongly linked to performance in the students I worked with,” Sternzus says. “I also felt, as a learner, that I was at my best when I was most curious. And I certainly could remember periods in my training where that curiosity was suppressed. In our study the trends that we found with regards to curiosity across the years confirmed what I had hypothesized.” Sternzus has since spearheaded a faculty development workshop on promoting curiosity in medical trainees.
So what might be the solution, especially as the move towards competency-based training programs may not reward curiosity, and at a time where companies in places like Silicon Valley — which invest in curious and talented minds — position themselves to be another gatekeeper of health care?
New work led by Jatin Vyas, MD, PhD, an infectious disease physician and researcher who directs the internal medicine residence at Massachusetts General Hospital, offers one idea. His team developed a two-week elective program, called Pathways, which allows an intern to investigate a case where the diagnosis is unknown or the science isn’t quite clear. They then present their findings to a group of up to 80 experienced physicians and trainees.
“What I have found is that many interns and residents have lots of important questions. If our attendings are not in tune with that — and it’s often due to a lack of time or expertise — the residents’ questions are oftentimes never discussed,” Vyas says. “When I was a resident, my mentors helped me articulate these important questions, and I believe this new generation of trainees deserve the same type of stimulation and the Pathways elective is one way to help address this.”
At the end of June, Pathways reached the end of its second year, and Vyas recounts that resident satisfaction, clinical-teacher satisfaction, and patient satisfaction were all high. “Patients have expressed gratitude for having trainees eager to take a fresh look at their case, even though they may not receive a breakthrough answer,” Vyas says.
The job of more experienced clinicians is to nurture curiosity of learners not just for the value it provides for the students, but for the benefits it poses for patients, Faith Fitzgerald, MD, an internist at the University of California Davis, has written. Physicians of the future, and the patients they care for, deserve this.

Terri Peters is an architect and researcher whose interdisciplinary work maps new trajectories of ecological design through contemporary practice, academic research and pop culture. She is an expert in sustainable housing and her research focuses on the architectural and social implications of the built environment, with a focus on more holistic qualitative parameters and wellbeing. She has published more than 20 peer reviewed journal and conference papers on sustainable housing and the impact and evaluation of daylight in homes. She is the editor of “Design for Health: Sustainable Approaches to Therapeutic Architecture” Architectural Design, 2017 and author of “Computing the Environment: Digital Design Tools for the Simulation and Visualisation of Sustainable Architecture” John Wiley and Sons 2018 which looks at how environmental data can be feedback into design process. She has a global perspective, having lived and worked in Vancouver, Tokyo, Paris, and London, and Copenhagen which was her adopted home for seven years. After 12 years abroad she is currently back in her native Canada, as an Assistant Professor at Ryerson University investigating the intersections of building science, environmental design, and wellbeing.
1.What prompted you to focus on healthcare architecture/design?
During my PhD work, which was focused on social housing I realized that the aspect of ‘people’ in that housing was missing, specifically the social impact of buildings. We know the buildings we spend time in, and our surroundings, greatly impact our wellbeing, but how does this become part of how we work? We need to be able to back up our observations and claims as designers and I think the new-ish movement towards evidence-based design, where design decisions are based on more than a designer’s intuition and experience, but also on results and interpretations of scientific evidence, can help improve design.
On a personal note, growing up in Canada and then living in bigger cities like London, where I did my professional degrees, and then in Copenhagen where I did my PhD, these places can be seen as quite dark, dreary places but I loved them. I always say maybe this is why I study daylight, because I appreciate every drop of it! In Copenhagen our apartments had lots of natural light and natural ventilation, it really shaped my thinking of how positive and life affirming a home can be. There’s this concept in Danish of hygge, or contentment, a cosy feeling. Another concept in Swedish is lagom which means something like “just enough is enough.” these are important concept in life to me and I lived and experienced them in my time in Denmark and they continue with me now.
So with all of that together, I realized that if we designed spaces in hospitals and other settings to be intentionally mood enhancing, that could make us all feel better.
2.Why is design important to our well-being?
When we design a building, we know that the decisions we make, however small, impact the moods, ideas and wellbeing of people using the spaces. Prioritizing daylight, fresh air, variety of spaces and environments with views to nature are some of the ways we address this depending on numerous other variables like site and program. We know that these decisions about building form, materials, adjacencies and sequence of spaces, and other variables change our perceptions of spaces and places and help shape our interactions with others.
Design, simply put, impacts how we feel, and not just in health care environments, but in our day to day experience in our homes and where we work. According to the World Health Organization, depression is the greatest cause of disability worldwide, and architects have a role to play in making spaces that do more than satisfy program, budget and site, but that make us feel better. In architecture schools, students learn about building performance and aspects of sustainable design, but rarely are methods, metrics or examples of health promotion or spaces that encourage positive social interactions explored in any depth. There is a wealth of knowledge in allied fields such as environmental psychology, and published studies in areas such as public health and sociology that can be tapped into to enrich the architecture curriculum. The increased focus in schools on environmental performance of buildings must be paired with understanding trade-offs and co-benefits for human performance and wellbeing – after all, buildings are for people.
3.You had an interesting personal brush with the healthcare system in two different countries. What was that like?
I had my two children in Copenhagen at Rigshospitalet, the Royal Hospital. It was built in the 1970s, but had windows that open, large rooms, and lots of daylight that enters into the lobby and patient rooms. I am really sensitive to my environment and I found that the quality of that room impacted my mood and experience.
And it was a major contrast with being in a Canadian hospital which wasn’t designed with these well-being components in mind. I broke my elbow last winter and was forced to wait in a place that had a low ceiling, was crowded, no fresh air. I actually felt sicker! And to top it off it was hard to find where I needed to go – I spent a lot of unnecessary time just navigating: it wasn’t designed with ease. In Denmark, the culture is built around design. The way people speak about it and appreciate it is really unique.
4.How did this experience impact your work as an architect and architecture professor now?
I have the challenge of teaching 1st year students what sustainability is, when often the work-life balance of many architecture students is poor. We hear that many of them are very stressed and finding it hard to thrive. We often discuss the power of building design as health promotion tools.
Architecture is unique in that you experience it whether you want to or not: the impact the buildings have on us is so extreme. When it comes to environmental psychology, which links to designing for health, we know that people have a natural inclination towards nature, whether it’s the savannah or long views. The
biophilia hypothesis (biophilic design) specifically describes this affinity to nature, daylight, natural materials.
Salutogenic design is another school of thought, which keeps stress reduction at the core. Earlier this year I became “WELL® Certified,” which is a new modality that evaluates qualitative and quantitative biophilia as it relates to health promotion. They measure things that are really exciting, because it’s centered around how people respond to being in a building. There’s a huge emphasis on daylight and nutrition, fitness, and well-being. For instance, they measure daylight differently. Traditionally in architecture we usually measure how much of the building’s floorplate is well lit without needing to turn on the light, its called spatial daylight autonomy and it means that area doesn’t need artificial light 50% of the time. The idea is related to productivity. The Well® Standard measures “equivalent melanopic lux,” which is a fancy way of describing the impact of light on the physiology of body, so for instance the impact on alertness, and sleep.
In my courses I describe a concept I coined called “superarchitecture,” which means buildings that do more than minimize the impact on the environment but that exploit and maximize the synergies and benefits to people: everything from building strategies like green roofs, daylight, fresh air and natural ventilation, shading where appropriate, outdoor spaces all these strategies that we know improve the environmental performance but that really also benefit our quality of life in tangible ways.
5.What does thriving mean to you?
Thriving is having time and energy to purposefully devote yourself to what you want to do. Technology can play a role in that, not only in making us feel more connected to each other, but by helping us make better decisions about what we want to do. It also involves how our environments help bolster our ‘emergency reserves’ to handle the unexpected, a protective buffer in other words. Last, when I think of thriving I think of resilience. There’s an emerging interest in architectural research and practice around building resilience and passive survivability. Much of how we think of the resilience of buildings may be applied to people as well. Daylight and views to the outside are big ones – we need these to feel at ease and to have the capacity to deal with disturbance and change. The current thinking around building resilience in building science and architecture is too focused on how buildings would survive in extreme weather or in an earthquake – what about us? How can our buildings help us survive and bounce back?
6.What are you most looking forward to with health design in general?
Looking forward to more interdisciplinary studies – for instance working with more healthcare professionals and building partnerships. I’ve been collaborating with psychologists regarding concepts of resilience in architecture and environmental psychology, which is undergoing a resurgence right now. I’m also excited about how we apply data, specifically how we can visualize the results of simulations, and how people can interact with visualizations and change our behavior to do more of what we want to.
I go to lots of industry meetings and workshops to understand what the potentials are with data and how they can benefit people.
NO MATTER WHAT you think about the causes of climate change, we know the planet is getting warmer. What most of us don’t realize is the impact climate change has on our health, which is why it’s concerning that last week’s UN Climate Change Summit did not identify health as one of the key action areas.
While about 70 percent of Americans believe that climate change is real (and in Canada, where I live, it’s a key issue ahead of the upcoming election), the majority of Americans surveyed do not believe it will harm them personally, according to a recent Yale Climate Opinion Map of public opinion data. In an earlier survey, less than one-third could name an example of climate endangering health. It’s time for a reality-check.
A 2016 Global Change Research Program Report listed seven broad areas in which climate change can affect health: through temperature-related death and illness, air quality, extreme events (such as disasters), vector borne diseases, water-related illness, food safety and nutrition, and mental health. Particular populations – such as low-income Americans, people with chronic medical conditions, Indigenous peoples, and persons with disabilities — may be disproportionately affected, as climate change has a direct impact on worsening every social determinant of health. Hurricane Dorian, which devastated the Bahamas, is yet another reminder that often the poorest communities are hardest hit.
A warmer planet means more potential for death and illnesses related to higher temperatures. It means lower air quality, especially in densely populated areas. Mosquitoes, ticks, and other carriers of infectious diseases can cover a wider geographic range and for a longer span of the year.
Let’s take Lyme disease: due to global warming, the ticks that carry Lyme are appearing in many more states, notably in the Midwest and in much of Canada. Other vector borne diseases are also likely to increase, though, as one researcher pointed out, the exact impact is unclear without further research.
Global warming also raises the chances of suffering heat stroke and heat stress, both risk multipliers for heart attacks. Asthma sufferers experience worse symptoms from the additional carbon dioxide in the atmosphere as well as dust and other particulate matter.
Air pollution currently causes up to 7 million premature deaths, according to the World Health Organization, and millions more visits to hospitals: One study points to the increase in amounts of near surface ozone as our planet warms as the cause. This issue was highlighted by the WHO at the UN Youth Climate Summit through immersive experiences in “air pollution pods.”
And those of us who enjoy seafood are at risk of neurotoxin exposure, due to increases in ocean algae blooms caused by warming temperatures. One study found that the toxic “domoic acid” increased as sea conditions became warmer.
Pregnant women are also at risk. In 2017, an extensive review of previous research on maternal health and climate change found that there are significant connections between extremes in temperatures and premature birth, low birthweight, and stillbirth.
We know that the US is one of the most sleep-deprived nations in the world, and a landmark paper has even linked warm temperatures related to climate change to insufficient sleep among those surveyed.
Lastly, we can’t forget the toll that climate change takes on mental health. The American Psychological Association summarized the effects in an extensive report, linking climate change disasters such as droughts and flooding to increased incidence of posttraumatic stress disorder and depression. And they found that worry about global warming can increase anxiety and depression, as well as substance abuse. This can be especially the case in places that have faced an environmental disaster.
Globally, no one is untouched. The WHO compiled a comprehensive set of resources that detail country-specific ways in which climate change affects human health. It estimates that between the years 2030 and 2050, 250,0000 additional deaths globally could be related to climate change, costing billions. The WHO hosted the first humanitarian conference on health and climate change in April.
In a 2017 article for the New England Journal of Medicine, the authors suggest a few ways in which doctors and patients can combat the effect of climate change on human health. For one, there is a unique opportunity to advocate for ‘green’ hospital design and eating less meat (which may also have health benefits, and have an impact on greenhouse gas emissions).
Earlier this summer, over 70 prominent medical organizations, including the American Academy of Pediatrics and the American Medical Association, called climate change the “greatest public health challenge of the 21st century,” and published a series of recommendations which include reducing greenhouse gases and improving access to clean water. In late August, the Doctors of British Columbia identified climate change as a major health care issue, which was followed by a similar alarm sounded by the Australian Medical Association.
Yet these calls to action can only go so far. Globally, all of us share the aspiration to obtain the highest level of health and well-being possible, however climate change has made this goal unreachable for many, and poses new challenges that even the best medicine won’t be able to fix. And as with most public health challenges, the most disadvantaged in society face the highest burden of risk. A public health approach values “upstream,” or preventative approaches to health disasters, which is why the WHO’s emphasis on the health impact of climate change matters.
While it’s unclear why it was not a core area identified in this year’s UN Climate Change Summit, weaving the health impact into the discussion will be crucial to setting much needed priorities for change before it’s too late.

“Forest bathing,” or immersing yourself in nature, is being embraced by doctors and others as a way to combat stress and improve health.
On a damp Saturday morning last August, I joined 10 others in the woods outside Ottawa, Canada, as part of a “forest bathing” session offered by a local wilderness resort.
First we sat in a circle on the leafy ground, each sharing a moment in nature from our childhood that filled us with joy. Next our guide, Kiki, a newly trained forest therapist who insisted we call her by her first name, led us on a mindful — and very slow — walk through the forest.
“What do you hear, smell, see?” Kiki asked, encouraging us to use all five senses to become deeply “immersed” in the experience.
An older woman in the group told us that she was undergoing a difficult and stressful period in her life, and that being among the trees felt “healing.” Others mentioned that the activity reminded them of walks they took as part of Boy Scouts or commented on the sounds: insects, birds, the rustling of leaves. I noticed the bright green acorns that dotted the forest floor, which reminded me of my childhood collection of acorns and chestnuts. Admittedly, I was also worried that the early morning rain was fertile ground for vicious mosquitoes (West Nile!) and ticks (Lyme!).
We ended the two-hour forest walk with a tea ceremony, sipping a concoction of white pine needles steeped in hot water.I left feeling relaxed and more at peace, though with at least two dozen bites from mosquitoes that seemed immune to DEET.
Kiki had been trained according to standards set by the Association of Nature and Forest Therapy, a professional group that has certified more than 300 people across North America to be forest therapy guides, among them psychotherapists, nurses and six M.D.s. The sessions are modeled after the Japanese tradition of shinrin-yoku,or forest bathing.
Over the years, I’ve had physician mentors recommend Richard Louv’s books, “The Nature Principle” and “Last Child in the Woods,” which describe the benefits of time spent in the wilderness, from stimulating creativity to reducing stress. Florence Williams’s best-selling book, “The Nature Fix,” has a chapter dedicated to the benefits of forest therapy. And now, it appears that more North American doctors are starting to incorporate spending time in forests into their practice.
Some small studies, many conducted in Japan and Korea, suggest that spending time in nature, specifically in lush forests, might decrease stress and blood pressure (especially in middle-aged men), improve heart-rate variability and lower cortisol levels while boosting one’s mood. An analysis of studies from 2010 that focused on exercising in nature found improvements in self-esteem, particularly among younger participants. Overall effects on mood were heightened when there was a stream or other body of water nearby.
But other studies have shown mixed results. A cross-sectional study from Korea found no change in blood pressure with forest bathing, and a systematic review from 2010 found that while time in the forest may boost mood and energy, any effects on attention, blood pressure and cortisol may not be statistically significant. Another recent review from Australia underscored the challenges of drawing causal links to disease prevention, with the authors calling for robust randomized controlled trials.
Several theories have been proposed as to why spending time in forests might provide health benefits. Some have suggested that chemicals emitted from trees, so-called phytoncides, have a physiological effect on our stress levels. Others suggest that forest sounds — birds chirping, rustling leaves — have a physiologically calming effect. Yet evidence to support these theories is limited.
On a recent visit to Japan, I met with Dr. Hiroko Ochiai, a surgeon based at Tokyo Medical Center, and her husband, Toshiya Ochiai, who is currently the chief executive of the International Society of Nature and Forest Medicine. Dr. Ochiai is trained in forest therapy and currently conducts most of her sessions with volunteers within a forest in Nagano, about three hours from Tokyo, with the help of a local guide, and plans to offer forest therapy soon at one of Tokyo’s largest hospitals.
“I usually encourage participants to sit or lie down on the forest ground and listen to the sounds,” she says. “The hypersonic natural world can be soothing, and things are always moving even while we are still. It can be very calming.”
Last June the Northside Hospital Cancer Institute in Atlanta began to formally offer forest therapy as part of a pilot project in collaboration with the Chattahoochee Nature Center. Twelve patients with newly diagnosed cancers recently signed up for a session, according to Christy Andrews, the executive director of Cancer Support Community Atlanta.
“It was a four-hour session that seemed to have an impact on the patients,” she said. “I remember one participant telling me afterward that it was a way to ‘steer away from cancer,’ and the group became very cohesive. I think it helped reduce the isolation in a way that’s different from a regular support group.”
Dr. Suzanne Bartlett Hackenmiller, an obstetrician-gynecologist based in Cedar Falls, Iowa, began guiding patients in her practice through the Prairie Woods in Hiawatha Iowa, though she has also led groups in forests around Des Moines. She became a certified guide through the Association of Nature and Forest Therapy three years ago and tries to tailor her offerings based on the group she is leading.
“I generally get a sense of where people are at. For some, it’s best for me to stick to the science, but others may literally want to hug a tree. The traditional tea ceremony at the end might turn some people off, so I’m conscious of that and adjust accordingly,” she says.
In one exercise, she has participants close their eyes as she guides them through experiencing the different senses, imagining feeling their feet growing into the ground like roots of a tree, for instance, listening to nearby sounds and observing how far they may extend, or smelling the air. It’s similar in many ways to a guided meditation.
“I recently held a session where four out of the 20 participants were in wheelchairs, so I found a local park that had plenty of trees and a paved sidewalk so everyone could enjoy it,” she says.
At the University of California, San Francisco, Benioff Children’s Hospital in Oakland, Dr. Nooshin Razani, a pediatric infectious disease doctor and director of the Center for Nature and Health, has offered a similar program for the past four years. The “Shine” program, linked to the East Bay Regional Parks District, offers “park prescriptions,” a movement that is growing in popularity, and aims to improve accessibility to nature for low income children.
One Saturday a month, Dr. Razani leads a group of up to 50 people through a lush forest of redwood trees and lakes on the outskirts of Oakland. The groups consist of patients ranging in age from a few months to 18 years, accompanied by at least one adult family member. A few of her medical colleagues — an orthopedic surgeon and primary care doctor — have also attended, and the Oakland-based pediatrics residency program at the medical centers invites doctors in training to join the group. Shine recently celebrated its 60th park outing.
“The accessibility part is huge for me. Many children don’t have access to green spaces in their community,” Dr. Razani says. “We also have evidence that supports the mental health aspects of spending time in forests, and for the resident doctors who participate, it’s a way to show them how children interact with nature based on the developmental stage. Sometimes the doctors’ need is just as much as the patients’.” In February, Dr. Razani published findings of a randomized trial that found that park visits — regardless of whether they were led by a guide or not — were associated with a decrease in stress three months after the visits.
A few hours after my own forest walk, the woman in our group who had mentioned her stress emailed me to say that she had checked her blood pressure afterward and noticed it was lower than usual. “It would be nice to see if there was a meaningful change from before, if they collected that information,” she wrote.
She had hit on one of the biggest issues around guided forest walks and forest therapy. Is it an evidence-based activity with proven clinical benefits?
The science is still lacking to prove it. But there is some evidence — as well as good old common sense — to suggest that spending time in nature is good for both the mind and body, whether done as a group or alone. It may be something we all need more of.
