Summer is in full swing, and the weather isn’t the only reason to head outdoors.

A recent study in the journal Environmental Science and Technology found that exercising outdoors makes you happier than exercising indoors. Participants reported feeling more revitalised and positive, with less tension, anger, confusion and depression when they exercised outside, compared to when they did the same exercise indoors. The participants also experienced greater satisfaction, and showed more interest in repeating the activity at a later date.
