One of the best ways to recover from stress and the daily self-control demands of your life is relaxation. Relaxing—even for just a few minutes—increases heart rate variability by activating the parasympathetic nervous system and quieting the sympathetic nervous system. It also shifts the body into a state of repair and healing, enhancing your immune function and lowering stress hormones. Studies show that taking time for relaxation every day can protect your health while also increasing your willpower reserve.
