A study found exposure to green space increases overall good health, and reduces risk of diabetes, preterm birth etc.

According to a new research from the University of East Anglia, 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 greenspace exposure are also more likely to report good overall health. Lead author Caoimhe Twohig-Bennett, said, "Spending time in nature certainly makes us feel healthier, but until now the impact on our long-term wellbeing 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 different 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 greenspaces, which included urban parks and street greenery.

The team analysed the difference in 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 greenspace significantly reduces people's levels of salivary cortisol - a physiological marker of stress.

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 socialising. Meanwhile, exposure to a diverse variety of bacteria present in natural areas may also have benefits for the immune system and reduce inflammation. 

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 greenspaces, particularly in urban residential areas and deprived communities that could benefit the most.” Twohig-Bennett said
