Managing Our Stress as Professionals

As noted by Dr. Gay Teurman, stress is an epidemic, and it wrecks your body and your brain in more ways than one. Stress can be attributed to your hair falling out, your clothes becoming tight and your immune system and your hormones, gut, mood, and poor, overloaded brain) go haywire just to name a few. The physiological damage due to stress can be phenomenal. The good news is, you don’t have to let stress hold you back.
