Results: When grumpiness takes over

(Source: outsideronline.com) A single hike, swim, run, or ride almost instantly makes you happier, thanks to a rush of feel-good endorphins. But turn that one afternoon outing into a long-term daily habit and you'll see bigger mood boosts every time, according to a study in Psychosomatic Medicine. Get out of the habit and your emotional drop will be much steeper, too. Additionally, staying active may fight anxiety. Michael Otto, a psychologist and professor at Boston University, explains that exercise can mitigate anxiety by firing up your fight-or-flight response, the evolutionary trigger for adrenaline, sweat, and increased heart rate when faced with a challenge. When you stop exercising, your body forgets how to handle stress. Because you've allowed your natural fight-or-flight response to atrophy, you're less likely to experience something tough—whether an interval workout or a stressful workplace relationship—in a positive way. Instead, you get anxious. "Many people skip the workout at the very time it has the greatest payoff. That prevents you from noticing just how much better you feel when you exercise," Otto said in an article for the American Psychological Society. "Failing to exercise when you feel bad is like explicitly not taking an aspirin when your head hurts. That's the time you get the payoff."
