Reconnecting with nature key for the health of people and the planet

Researchers are the first to investigate -- within a single study -- the contribution of both nature contact and connection to human health, well-being and pro-environmental behaviors.

Individuals who visit natural spaces weekly, and feel psychologically connected to them, report better physical and mental wellbeing, new research has shown.

Alongside the benefits to public health, those who make weekly nature visits, or feel connected to nature, are also more likely to behave in ways which promote environmental health, such as recycling and conservation activities.

The findings of the study, published in the Journal of Environmental Psychology, indicate that reconnecting with nature could be key to achieving synergistic improvements to human and planetary health.

The study was conducted by researchers at the University of Plymouth, Natural England, the University of Exeter and University of Derby, and is the first to investigate -- within a single study -- the contribution of both nature contact and connection to human health, wellbeing and pro-environmental behaviours.

The findings are based on responses to the Monitor of Engagement with the Natural Environment (MENE) survey, commissioned by Natural England as part of DEFRA's social science research programme. The team looked at people's engagement with nature though access to greenspace, nature visits and the extent to which they felt psychologically connected to the natural world.

Lead author Leanne Martin, of the University of Plymouth, said: "In the context of increasing urbanisation, it is important to understand how engagement with our planet's natural resources relate to human health and behaviour. Our results suggest that physically and psychologically reconnecting with nature can be beneficial for human health and wellbeing, and at the same time encourages individuals to act in ways which protect the health of the planet."

Marian Spain, Chief Executive of Natural England added: "It's a top priority for Natural England to unlock the potential of the natural environment to help address the challenges we are facing as a society: poor physical health and mental wellbeing; the climate change crisis and the devastating loss of wildlife.

"These findings give vital new insights of the need to not just increase contact with nature, but about the sorts of experience that really help people build an emotional connection, which is key to unlocking health benefits as well as inspiring people to taking action to help their environment. We look forward to using the research as we work with our many partners to support more people from all walks of life to benefit from thriving nature."

A Walk in the Park Gives Mental Boost to People with Depression

A walk in the park may have psychological benefits for people suffering from depression. In one of the first studies to examine the effect of nature walks on cognition and mood in people with major depression, researchers in Canada and the U.S. have found promising evidence that a walk in the park may provide some cognitive benefits.

The study was led by Marc Berman, a post-doctoral fellow at Baycrest's Rotman Research Institute in Toronto, with partners from the University of Michigan and Stanford University. It is now published online, ahead of print publication, in the Journal of Affective Disorders.

"Our study showed that participants with clinical depression demonstrated improved memory performance after a walk in nature, compared to a walk in a busy urban environment," said Dr. Berman, who cautioned that such walks are not a replacement for existing and well-validated treatments for clinical depression, such as psychotherapy and drug treatment.

"Walking in nature may act to supplement or enhance existing treatments for clinical depression, but more research is needed to understand just how effective nature walks can be to help improve psychological functioning," he said. Dr. Berman's research is part of a cognitive science field known as Attention Restoration Theory (ART) which proposes that people concentrate better after spending time in nature or looking at scenes of nature. The reason, according to ART, is that people interacting with peaceful nature settings aren't bombarded with external distractions that relentlessly tax their working memory and attention systems. In nature settings, the brain can relax and enter a state of contemplativeness that helps to restore or refresh those cognitive capacities.

In a research paper he published in 2008 in Psychological Science, Dr. Berman showed that adults who were not diagnosed with any illness received a mental boost after an hour-long walk in a woodland park -- improving their performance on memory and attention tests by 20 percent -- compared to an hour-long stroll in a noisy urban environment. The findings were reported by The Wall Street Journal, The Boston Globe, The New York Times, and in the Pulitzer Prize finalist book by Nicholas Carr, The Shallows: What the internet is doing to our brains.

In this latest study, Dr. Berman and his research team explored whether a nature walk would provide similar cognitive benefits, and also improve mood for people with clinical depression. Given that individuals with depression are characterized by high levels of rumination and negative thinking, the researchers were skeptical at the outset of the study that a solitary walk in the park would provide any benefit at all and may end up worsening memory and exacerbating depressed mood.

For the study, 20 individuals were recruited from the University of Michigan and surrounding Ann Arbor area; all had a diagnosis of clinical depression. The 12 females and eight males (average age 26) participated in a two-part experiment that involved walking in a quiet nature setting and in a noisy urban setting. Prior to the walks, participants completed baseline testing to determine their cognitive and mood status. Before beginning a walk, the participants were asked to think about an unresolved, painful autobiographical experience. They were then randomly assigned to go for an hour-long walk in the Ann Arbor Arboretum (woodland park) or traffic heavy portions of downtown Ann Arbor. They followed a prescribed route and wore a GPS watch to ensure compliance. After completing their walk, they completed a series of mental tests to measure their attention and short-term/working memory and were re-assessed for mood. A week later the participants repeated the entire procedure, walking in the location that was not visited in the first session.

Participants exhibited a 16 percent increase in attention and working memory after the nature walk relative to the urban walk. Interestingly, interacting with nature did not alleviate depressive mood to any noticeable degree over urban walks, as negative mood decreased and positive mood increased after both walks to a significant and equal extent. Dr. Berman says this suggests that separate brain mechanisms may underlie the cognitive and mood changes of interacting with nature.
