The Science Behind Exercise's Mood-Lifting Effects - Analysis by Dr. Joseph Mercola


  • Research suggests exercising is a powerful tool for the prevention and management of depression, in part by normalizing insulin resistance 
  • Mechanistic studies have also linked the antidepressant effects of exercise to molecular mechanisms involving kynurenine, myokines, BDNF, the endocannabinoid system and beta endorphin 
  • By allowing for more tryptophan to be transported into your brain, exercise raises your serotonin and inhibits conversion into kynurenine, thereby boosting mood and preventing depression 
  • Low BDNF levels have been implicated as a central component of depression, as depressed patients typically have lower levels than healthy controls 
  • While exercise euphoria is typically attributed to the release of endorphins, vigorous exercise also dramatically increases anandamide — an endocannabinoid — in the body, which influences opioid and endorphin receptors. The higher your anandamide level, the better you feel
