In 2019, a University of Exeter team analyzed survey answers from nearly 20,000 people in England. Those who had spent at least 120 minutes in nature the previous week, including parks, woods and beaches, were more likely to report good health and high well-being. Below that, no clear benefit; beyond 200 to 300 minutes, no extra gain. One long outing or several short ones worked equally well. It's a correlation, not yet proof.

In 2003, Johnson and Goldstein compared European countries. Where you must tick a box to become a donor, consent rates ranged from 4% to 28%.
