Exercise-induced endorphins significantly enhance mood by acting as natural painkillers and mood elevators. These neurotransmitters create feelings of happiness and euphoria, often referred to as the "runner’s high." Regular physical activity increases endorphin levels, which can reduce feelings of stress and anxiety while promoting overall emotional well-being. Consequently, incorporating exercise into daily routines not only benefits physical health but also serves as an effective tool for improving psychological resilience and mood stability.
