Exercise plays a vital role in the body's response to stress. Physical activity stimulates the release of endorphins, which are hormones that promote feelings of well-being and act as natural painkillers. Regular exercise reduces levels of cortisol, a stress hormone, and enhances overall mood. It also provides a healthy outlet for frustration and anxiety, allowing individuals to clear their minds. Additionally, engaging in physical activity fosters a routine that can boost self-esteem and resilience against emotional stressors, thereby promoting overall mental health.
