Endorphins play a crucial role in exercise-induced happiness. These are natural chemicals produced by the body in response to physical activity, and they help reduce pain perception while promoting feelings of well-being. When endorphins are released during exercise, they can create a sense of euphoria, often referred to as a "runner’s high." Regular physical activity can lead to increased endorphin levels, which may help combat stress, anxiety, and depression, enhancing overall mental health and life satisfaction.
