A new study quantifies it. “The study examined data from nearly 20,000 people in England who took part in the Monitor of Engagement with the Natural Environment Survey from 2014 to 2016, which asked them to record their activities within the past week. It found that people who spent two hours a week or more outdoors reported being in better health and having a greater sense of well-being than people who didn’t get out at all.” – The New York Times
