The 1988 movie “The Great Outdoors” is the slapstick tale about a series of disasters that befall a family getaway planned by Chet (John Candy) and his brood at a bucolic lake resort in rural Wisconsin.

Tranquility is shattered when in-laws Roman (Dan Aykroyd) and Kate (Annette Bening) arrive uninvited with their kids.

Although Gene Siskel said in his review, “The movie stinks — all the way through,” it did get some things right. Stressed-out city dwellers do need to reconnect with nature, and it needs to be done in peace and quiet.

Researchers from the University of Michigan recently published a study of 36 city dwellers who were prescribed a “nature pill,” and had their levels of the stress hormone cortisol measured before and after they took this stress-busting prescription.

Reporting results in the journal Frontiers in Psychology, the scientists said that when participants put themselves in an environment where they interacted with nature for 20 minutes at least three times a week, their stress hormone levels dropped significantly.

If they stretched that interval to 20-30 minutes, cortisol levels decreased the most. But adding even more time didn't cause as big a drop.

Talk to your doc about getting a prescription for this free and easy way to help manage high blood pressure, headaches, inflammation, insomnia, and moodiness. Or prescribe it for yourself.

Either way, you choose the location, time, and duration. Remember to take the dose of nature in daylight; don't do any aerobic exercise (just a gentle stroll); don't use social media, your phone, or the Internet; and don't do anything that interrupts your solitude.
