Working out benefits your mental health in several ways. Here are two key reasons: 1. Stress Reduction: Physical activity helps lower levels of stress hormones like cortisol while releasing endorphins, which are natural mood elevators. This can leave you feeling more relaxed and happier after a workout. 2. Improved Mood and Reduced Anxiety/Depression: Regular exercise has been shown to alleviate symptoms of anxiety and depression by boosting serotonin, dopamine, and other brain chemicals.
