Endorphins are neurotransmitters produced by the body that help alleviate pain and induce feelings of pleasure or euphoria, commonly referred to as the "runner's high." These natural chemicals are released during and after physical activity, contributing to a positive mood while reducing stress and anxiety levels. Regular exercise increases endorphin levels, which can enhance overall mental health and emotional well-being. This relationship between endorphins and exercise emphasizes the psychological benefits of physical activity, encouraging people to engage in regular workouts for both physical and mental health.
