Exercise influences stress hormones like cortisol by reducing their levels in the body. Regular physical activity lowers cortisol, alleviating stress and improving overall mental health. Exercise also helps stimulate the production of endorphins, which have mood-enhancing properties that counteract stress. However, excessive or intense exercise can lead to an increase in cortisol, highlighting the importance of balancing workouts. Incorporating stress-relief practices, such as yoga or mindfulness alongside regular exercise, can further optimize hormonal balance and stress management.
