What if a walk in a green environment could reshape brains, recalibrate sense of time, and stave off mental health conditions? If the research trends are true, you might soon find yourself writing prescriptions of 20 minutes of nature per day.
In the wake of the pandemic, the British government allocated more than £5 million to pandemic recovery efforts that specifically involved green spaces. Since then, it has committed even more funding toward an expansive social prescribing program that connects patients to “link workers” who determine personal care needs and facilitate community and volunteer-based interventions. These can include group walking and volunteering to help out in community gardens or conservation efforts. Similar green programs can be found in Japan, where shinrin-yoku (forest bathing) was recently adopted as a national health strategy, and in the United States and Canada.
“Disconnection from nature is a major part of the health problems that we have on this planet,” said William Bird, a UK-based general practitioner, green prescriber, and CEO of Intelligent Health, which is geared toward building healthy, active, and connected communities. Dr. Bird received the prestigious Member of the Order of the British Empire (MBE) in 2010 for services related to physical activity and health.
“Our brains are designed to connect to nature ... and we haven’t lost that instinct,” he explained. “Once we are with birdsong and water flowing and greenery, cortisol levels drop, our central vagus nerve improves, our fight and flight [response] disappears, and we start to be more receptive to other people.”
Shifting Time Perception and Health
Ricardo A. Correia, PhD, a biologist and researcher at the University of Helsinki in Finland, said he believed that the mechanism for at least some of these outcomes might be differences in how time is perceived. In a perspective that appeared in March in People and Nature, Dr. Correia explored how the “services” that nature provides shift time perceptions and, in turn, regulate overall well-being.
“I reached the realization that there was some evidence for the shift in some of the dimensions that we use to make sense of time in urban vs natural environments,” he told this news organization.
Dr. Correia explained that human time perception facilitates understanding cause and effect, so we can act in a way that allows us to survive.
“Time perception in humans is really complex and multifaceted,” he said. “The way that we make sense of time is not directly attached to any sensory organ, but rather goes through a range of cognitive, emotional, and bodily processes, all of which vary from person to person.”
Dr. Correia pointed to evidence showing that time perception is shorter in urban environments and longer in natural ones. This, in turn, influences attention and attention restoration. “When we live in cities, we are exposed to similar sorts of demanding environments, increased time pressures, less time for oneself and for recreational purposes,” he said. “Ever-mounting pressure on daily demands plus processes we use to make sense of time, especially attention, means that we pay a cognitive toll.”
Dr. Correia posits that it might be possible to recalibrate time perception, but only by breaking the cycle of exposure.
“If we are always exposed to fast-paced lifestyles, we become attuned to them and get caught up in an endless loop.” This cycle can be broken, Dr. Correia explained, by increasing exposure to natural environments. This leads to positive emotions, a sense of being in the present, and a heightened sense of mindfulness, all of which help mitigate the physical and mental health outcomes commonly associated with time scarcity.
Brain-Mental Health Benefits
To date, there is quite a bit of research exploring the impacts of exposure to nature on the brain. For example, data have shown that adolescents raised exclusively in rural environments have a larger hippocampus and better spatial processing than children exclusively raised in cities. Other research demonstrated that spending just an hour in the forest led to a decline in amygdala activity in adults, whereas it remained stable after walking in an urban setting, underscoring the salutogenic effects on brain regions related to stress. There is also evidence from a 10-year longitudinal study of more than 2 million Welsh adults that highlights the value of proximity to green or blue (eg, lakes and rivers) spaces and common mental health conditions, with every additional 360 meters to the nearest green or blue space associated with 10% greater odds of anxiety and depression.
Dr. Bird said there has been a massive sea change in attitudes among general practitioners, who have come around to embracing the concept of nature as medicine. This shift among peers, who teased him in the 1990s about his green walking and conservation prescriptions, portends a bandwagon of epic proportions that could benefit patients. He said that he was especially hopeful that green prescriptions will become mainstream in certain conditions, especially those like depression and anxiety that are resistant to medication.
But Dr. Bird cautions that primary care professionals need to be mindful. “Patients need to know that it’s real science, otherwise they’ll think that they’re being pawned off or dismissed,” he said. “I try to put real evidence behind it and explain that there’s no contraindication. The main thing is to start where patients are, what they’re feeling, and what they need. Some people just don’t like nature,” he said.
