More than 500 million people live with depression or anxiety.

A University of Gothenburg clinical trial found that most patients with anxiety who did 12 weeks of aerobic and strength training saw major improvements. The more vigorously people worked out, the more their anxiety symptoms lessened. To alleviate depression, one solution is to spend less time sitting. Exercise may help ease symptoms of anxiety and depression by releasing feel-good chemicals called endorphins, stimulating the growth of nerve cell connections in brain regions that regulate mood and take the mind off negative thoughts.
