Physical activity significantly affects mood and stress relief. Engaging in exercise releases endorphins, which are chemicals in the brain that promote feelings of happiness and euphoria. Regular physical activity can reduce levels of the body's stress hormones, such as cortisol, contributing to lower stress and anxiety. Exercise can also create a sense of accomplishment and improve overall mental clarity. Moreover, incorporating physical activity into daily life can provide a healthy outlet for managing emotional challenges and build resilience against stressors.
