Exercise has a profound impact on stress levels, acting as a natural stress reliever. Physical activity stimulates the release of endorphins, neurotransmitters that promote feelings of happiness and well-being. Additionally, exercise can lower levels of the body's stress hormones, such as cortisol, creating a calming effect. Regular physical activity also aids in improving sleep quality, which is vital for stress management. Furthermore, exercise can provide opportunities for social interaction and distraction from daily stressors, thereby enhancing mood and mental resilience.
