It is well understood that physical activity and exercise can significantly improve mental well-being by boosting mood, cognitive function, physical health, sleep quality, and self-esteem. However, a growing body of evidence shows that higher activity level is correlated strongly with a lower incidence of diagnosed mental illnesses.
Depression is the leading cause of mental-health related disability and disease burden worldwide and is associated with premature death from suicide and other illnesses. A recent meta-analysis published in JAMA Psychiatry found a large and significant association between levels of physical activity and instances of depression.[1] The analysis reviewed 15 studies comprising almost 200 000 participants and suggested there are significant mental health benefits from being physically active, even at activity below typical public health recommendations (~3 hr / week of brisk walking or equivalent). Other studies have shown that as little as 15 minutes of light to moderate exercise is as effective as anti-depressant medication in alleviating symptoms of depression and anxiety – without pharmacological side-effects. Even light exercise can reverse symptoms of depression by reducing stress, tension, and irritability as well as improve sleep, energy and concentration.
