Feeling down? Taking a walk could help, new research shows.
The more steps we take, the less likely we are to feel depressed, according to a JAMA Network Open paper published in December. Researchers analyzed 33 studies examining the movements of nearly 100,000 adults using smartphones, pedometers and other fitness trackers. Those who clocked more daily steps were less likely to report depressive symptoms or be diagnosed with the condition than those who walked less.
