Parks are for more than play. A new study links green spaces to healthy bodies—and minds.

Excerpts:

A new study found that inner-city kids living in neighborhoods with more green space gained about 13% less weight over a two-year period than kids living amid more concrete and fewer trees.

…The new research, published in the American Journal of Preventive Medicine, isn't the first to associate greenery with better health, but it does get us closer to identifying what works and why.

…But green space is good for the mind too; research by environmental psychologists has shown that it has cognitive benefits for children with attention-deficit/ hyper activity disorder (ADHD). In one study, simply reading outside in a green setting improved kids' symptoms.
