This document discusses how exercise can affect emotions in 3 main ways: 1) Exercise releases endorphins which improve mood and make you feel happier. It provides a "runner's high" similar to the effects of antidepressants. 2) Physical activity reduces stress and anxiety by releasing chemicals in the brain and boosting energy levels, helping to clear tension from the body and mind. 3) Exercise may help relieve feelings of sadness or depression by naturally promoting the release of feel-good chemicals like endorphins and serotonin that combat depression. Taking care of one's health through exercise can also help alleviate symptoms of depression.
