Exercise combats feelings of anxiety and depression by promoting the release of endorphins, often called "feel-good" hormones. Physical activity can enhance mood, reduce stress, and improve overall mental health. It also encourages better sleep patterns and provides an opportunity for social interaction, which can alleviate feelings of loneliness. Regular exercise can create a positive feedback loop by fostering a sense of accomplishment and increasing self-esteem. Ultimately, it serves as an effective tool in managing both anxiety and depression, leading to improved emotional resilience and psychological well-being.
