At this point, everyone and their mother are begging you to go outside and spend time in nature. There’s decades’ worth of research to support it making you feel better, both mentally and physically.

Now, a research study is drilling down into the details to find that even as little as 10 minutes spent outside could help your mental health.

Published in Ecopsychology, this new analysis scoured three decades of research on how nature impacts mental health. From an initial pool of 14,168 studies, researchers homed in on 45 that involved almost 1,500 adults with diagnosed mental health conditions. These studies ranged from brief urban park visits to extended wilderness immersions.

The results? Well, according to the analyses, whether research participants spent just 10 minutes in a city park or several days in the wild, they reported experiencing positive mental health benefits. Some studies examined frequent short visits into nature, while others looked at longer, continuous exposure.

Notably, the analysis indicated that outdoor spaces based around water, like lakes and oceans, and camping and gardening activities, had the greatest positive effect. But all approaches, even urban nature, showed encouraging results. Additionally, nature’s positive effects appeared even greater for those diagnosed with mood disorders, including depression or bipolar disorder.

So, if the idea of a weeklong wilderness trek feels daunting, rest easy. A brief escape to a nearby park is a practical, low-cost option that could be just as beneficial — and you won’t need to bring toilet paper or bug spray.
