Even after living on a relatively rural island in Florida for more than 20 years, I still consider myself a city girl. I burn easily in the sun and bugs love to bite me, so I really don’t like spending time outdoors all that much. But a study done by researchers at the University of Michigan has given me incentive.
People have always been urged to commune with nature to reduce stress, but just how much time was needed and what kind of experience would do the trick weren’t known.
Lead author of the research, Dr. MaryCarol Hunter, says people who spent 20 minutes a day in nature saw a significant reduction in the stress hormone cortisol. The “nature pill” prescription is sitting or walking in a place that provides you with a sense of nature.
Participants were studied over an eight week period. They were to spend 10 minutes or more, three days a week anywhere outside that made them feel like they’d interacted with nature. There were a few constraints to minimize factors known to influence stress: take the nature pill in daylight, no aerobic exercise, and avoid the use of social media, internet, phone calls, conversations and reading.
The 20 to 30 minute window produced the highest reduction in cortisol. After that, the benefit continued but at a lesser rate.
I guess I can spare 20 minutes outside on a stressful day, and what day isn’t? How do you feel about taking a “nature pill?”
