Regular exercise significantly impacts hormone levels by enhancing the secretion of endorphins, which promote feelings of happiness and reduce stress. It also boosts the production of testosterone and growth hormone, aiding muscle growth and recovery. Conversely, it can lower levels of cortisol, the stress hormone. Regular activity helps improve insulin sensitivity, regulating blood sugar levels more effectively. Overall, regular exercise can lead to a more balanced hormone profile, contributing to both physical and mental well-being.
