Natural History Wanderings

You don’t need to go on a 10-mile hike or sign up for a wilderness retreat to tap into nature’s many benefits. A 2025 meta-analysis in Nature Cities found that spending just 15 minutes outside, even in a city, is enough to make a meaningful difference.

“Nature disconnects you from the things you’ve been stressing about and puts you in the present moment,” says study co-author Anne Guerry, co-executive director of the Natural Capital Alliance at Stanford University. Her team evaluated 78 experimental studies including some 6,000 people. “That’s not just looking at associations, but actually doing experiments”—stronger evidence than the usual research linking leafy neighborhoods to better moods.

Among the study’s findings: Exposure to urban nature reliably brought down anxiety, depression, stress, anger, and fatigue, while increasing vitality, vigor, positive mood, and restorative effect. While longer sessions outside (45 minutes and more) produced the biggest gains in stress reduction and vitality, shorter exposures still delivered real effects.
