Exercise has been shown to be an effective tool for managing depression and mood disorders. Physical activity can have a positive impact on mental health by reducing symptoms of depression, anxiety, and stress. When we exercise, our bodies release endorphins, which are natural mood lifters. Additionally, regular exercise can improve sleep, boost self-esteem, and provide a sense of accomplishment, all of which are beneficial for managing mood disorders.

For example, a study published in the American Journal of Preventive Medicine found that individuals who engaged in regular physical activity were less likely to experience symptoms of depression. Another study in the Journal of Psychiatric Research demonstrated that exercise was as effective as medication in reducing symptoms of depression.
