According to a study conducted in 2009 by the US Environmental Protection Agency, the typical American spends 90 percent of his or her time indoors.
However, the editors of the Harvard Health Letter stress that there are at least five health benefits from spending more time outside.
First, vitamin D levels are increased as the skin is exposed to sunshine, reducing risk of some chronic diseases such as cancer and osteoporosis.
Second, being outside is an invitation to be more active, especially for children.
Third, research indicates that sunlight tends to elevate a person’s mood.
Fourth, time in nature appears to improve concentration particularly in those with ADHD.
And last, natural light may help the body heal faster and experience less pain and stress.
