Exercise influences the production of stress hormones such as cortisol and adrenaline. While moderate exercise can help regulate stress and lower cortisol levels over time, excessive or high-intensity workouts may temporarily increase these hormones, potentially leading to anxiety or fatigue if not managed properly. Regular physical activity is generally associated with improved mood and stress relief due to the release of endorphins, the body's natural feel-good chemicals. This balance can promote overall mental health, showcasing exercise's dual role in managing physical exertion and psychological resilience.
