Endorphins released during exercise significantly influence mood by promoting feelings of happiness and reducing stress. Known as the body’s natural painkillers, endorphins interact with the brain’s receptors to create a sense of well-being, often referred to as the "runner's high." This biochemical response can alleviate symptoms of anxiety and depression, contributing to improved mental health. Regular physical activity also fosters resilience, allowing individuals to better manage stressors in daily life. Therefore, engaging in consistent exercise not only enhances physical fitness but also supports overall emotional wellness.
