LONDON (Dispatches) -- Spending at least two hours a week in nature may be a crucial threshold for promoting health and wellbeing, according to a new large-scale study.
Research led by the University of Exeter, published in Scientific Reports and funded by NIHR, found that people who spend at least 120 minutes in nature a week are significantly more likely to report good health and higher psychological wellbeing than those who don't visit nature at all during an average week. However, no such benefits were found for people who visited natural settings such as town parks, woodlands, country parks and beaches for less than 120 minutes a week.
The study used data from nearly 20,000 people in England and found that it didn't matter whether the 120 minutes was achieved in a single visit or over several shorter visits. It also found the 120 minute threshold applied to both men and women, to older and younger adults, across different occupational and ethnic groups, among those living in both rich and poor areas, and even among people with long term illnesses or disabilities.
There is growing evidence that merely living in a greener neighbourhood can be good for health, for instance by reducing air pollution. The data for the current research came from Natural England's Monitor of Engagement with the Natural Environment Survey, the world's largest study collecting data on people's weekly contact with the natural world.
