In the late 1990s, Frances Kuo […] and her colleagues compared women randomly assigned to various apartments. Some had a view of nothing but concrete sprawl, the blacktop of parking lots and basketball courts. Others looked out on grassy courtyards filled with trees and flowerbeds. Kuo then measured  the two groups on a variety of tasks, from basic tests of attention to surveys that looked at how the women were handling major life challenges. She found that living in an apartment with a view of greenery led to significant improvements in every category.

What happened? Kuo argues that simply looking at a tree “refreshes the ability to concentrate,” allowing the residents to better deal with their problems. Instead of getting flustered and angry, they could stare out the window and relax. In other words, there is something inherently “restorative” about natural setting – places without people are good for the mind.

Green, open spaces are good for the soul.
