Exercise zaps stress
While everyone knows exercise promotes a healthy heart, researchers are constantly learning more about how it minimizes stress. Multiple studies from the University of Colorado at Boulder have shown that physiological responses to stress from the brain, hormonal system, and immune system are all moderated by regular exercise. And while all exercise is healthy, moderately intense exercise, like tennis significantly reduces anxiety too, according to research from the University of Missouri.
