The relationship between fitness level and stress reduction is well-established. Regular physical activity promotes the release of endorphins, which are chemicals that enhance mood and alleviate stress. Higher fitness levels improve cardiovascular health, boost energy, and increase resilience to stressors. Individuals who engage in regular exercise are better equipped to manage anxiety and tension, leading to improved mental health outcomes. Additionally, fitness routines often provide a structured environment, enhancing feelings of control and accomplishment, further promoting a positive response to stress.
