"Over the past year of shelter-in-place restrictions, we've learned how valuable and fulfilling it can be to spend time outdoors in nature, especially for city-dwellers," said study lead author Roy Remme, a postdoctoral researcher at the Stanford Natural Capital Project at the time of research. "We want to help city planners understand where green spaces might best support people's health, so everyone can receive nature's benefits."

In cities, nature provides cooling shade to neighborhood streets, safe harbor for pollinators and rainwater absorption to reduce flooding. It's widely understood that physical activity improves human health, but how parks, lakes, trees and other urban green spaces boost physical activity and overall wellbeing is an unsolved piece of the puzzle.
