Regular physical activity helps mitigate anxiety and depression by promoting the release of endorphins, which are chemicals in the brain that act as natural mood lifters. Exercise can improve self-esteem and provide a sense of achievement, contributing to better mental well-being. It also helps to reduce the level of stress hormones in the body and promotes better sleep, which is crucial for emotional health. Overall, regular physical activity serves as an effective adjunct to therapeutic interventions for mood disorders.
