Scientists have proven what mothers have been telling children for years: “Get outside of the house for a while. The fresh air will do you some good.”

Citing a collection of five studies*, researchers show that enjoying the sights and sounds of nature can produce noticeable improvements in physical and mental energy. Exposure to novel objects in wilderness settings tends to replenish attention and spark mental energy.

Even viewing pictures of nature, they say, may help to restore healthy moods, “including lower feelings of stress and depression.” These observations help to explain why popular vacation choices often involve spending time in novel nature settings.

So do as mothers and scientists suggest: go for a walk outdoors. Experience something new and natural along the way, allowing the experience to rejuvenate the energies of your mind, body, and spirit.
