How long does it take to get a dose of nature high enough to make people say they feel healthy and have a strong sense of well-being?


Precisely 120 minutes.


In a study of 20,000 people, a team led by Mathew White of the European Centre for Environment & Human Health at the University of Exeter, found that people who spent two hours a week in green spaces — local parks or other natural environments, either all at once or spaced over several visits — were substantially more likely to report good health and psychological well-being than those who don’t.
