Exercise impacts stress levels and the body by triggering the release of endorphins, which are natural mood lifters. Regular physical activity reduces levels of the body's stress hormones, such as cortisol, while enhancing sleep quality and overall mood. Moreover, exercise facilitates a sense of accomplishment and contributes to feelings of well-being, which can help combat anxiety and depression. Physically, it also aids in improving cardiovascular health, boosting immune function, and increasing stamina. Thus, engaging in regular exercise can lead to significant improvements in both mental and physical health.
