It’s official – spending time outside is good for you – Study

One of my favorite songs as a kid in the 1940’s was “Don’t fence me in.”
Here are some of the lyrics:
Oh, give me land, lots of land under starry skies above
Don’t fence me in
Let me ride through the wide open country that I love
Don’t fence me in

It appears I still feel that way, particularly when it comes to exercise. Working out in the health club really turns me off.

A new report reveals that exposure to green space reduces the risk of type II diabetes, cardiovascular disease, premature death, preterm birth, stress, and high blood pressure.

Populations with higher levels of green space exposure are also more likely to report good overall health – according to global data involving more than 290 million people.

Lead author Caoimhe Twohig-Bennett, from UEA’s Norwich Medical School, said: “Spending time in nature certainly makes us feel healthier, but until now the impact on our long-term well being hasn’t been fully understood.

“We gathered evidence from over 140 studies involving more than 290 million people to see whether nature really does provide a health boost.”

The research team studied data from 20 countries including the UK, the US, Spain, France, Germany, Australia and Japan – where Shinrin yoku or ‘forest bathing’ is already a popular practice.

‘Green space’ was defined as open, undeveloped land with natural vegetation as well as urban green spaces, which included urban parks and street greenery.

The team analyzed how the health of people with little access to green spaces compared to that of people with the highest amounts of exposure.

“We found that spending time in, or living close to, natural green spaces is associated with diverse and significant health benefits. It reduces the risk of type II diabetes, cardiovascular disease, premature death, and preterm birth, and increases sleep duration.

“People living closer to nature also had reduced diastolic blood pressure, heart rate and stress. In fact, one of the really interesting things we found is that exposure to green space significantly reduces people’s levels of salivary cortisol – a physiological marker of stress.

“This is really important because in the UK, 11.7 million working days are lost annually due to stress, depression or anxiety.”

“Forest bathing is already really popular as a therapy in Japan – with participants spending time in the forest either sitting or lying down, or just walking around. Our study shows that perhaps they have the right idea!

“Although we have looked at a large body of research on the relationship between greenspace and health, we don’t know exactly what it is that causes this relationship.

“People living near green space likely have more opportunities for physical activity and socializing. Meanwhile, exposure to a diverse variety of bacteria present in natural areas may also have benefits for the immune system and reduce inflammation.

“Much of the research from Japan suggests that phytoncides – organic compounds with antibacterial properties – released by trees could explain the health-boosting properties of forest bathing.”

Study co-author Prof Andy Jones, also from UEA, said: “We often reach for medication when we’re unwell but exposure to health-promoting environments is increasingly recognized as both preventing and helping treat disease. Our study shows that the size of these benefits can be enough to have a meaningful clinical impact.”

The research team hope that their findings will prompt doctors and other healthcare professionals to recommend that patients spend more time in green space and natural areas.

Twohig-Bennett said: “We hope that this research will inspire people to get outside more and feel the health benefits for themselves. Hopefully our results will encourage policymakers and town planners to invest in the creation, regeneration, and maintenance of parks and green spaces, particularly in urban residential areas and deprived communities that could benefit the most.”

The research was funded by the Centre for Diet and Activity Research (CEDAR), which is studying the factors that influence diet and physical activity behaviors, developing and shaping interventions, and helping shape public health policy and practice. CEDAR are driven by the overall goal of supporting effective interventions to change diet and physical activity behaviors at the population level.
