Psychological Just the fact that your body is beginning to look and feel better makes you feel better about yourself. Exercise gives you the ability to empower yourself. Chemical Exercise also helps release two brain boosting chemicals, serotonin and endorphins. Serotonin is a neurotransmitter and a mood enhancer. Low levels of serotonin can leave you feeling anxious and depressed.
Endorphins are natural pain killers.
To gain any benefit from endorphins, you need to exercise more intensely. Just do enough to boost your spirits, not run yourself into the ground. The good news is that you don t have to show larger muscles or tremendous gains in endurance to feel better emotionally. Nutrition also has a vital role on your mental outlook. Avoiding refined and processed foods are your best bet.
