If people around you drive you crazy, laugh. You'll be healthier if you do. Laughter relaxes the body for as much as 45 minutes. The harder you laugh, the more tension you release. After laughing, the pulse rate drops below normal and muscles become deeply relaxed.
Laughter even helps to control pain.
It distracts your attention, reduces tension and increases the body's natural painkillers, known as endorphins. Laughter also exercises the lungs, stimulates the circulatory system and increases oxygen in the blood. It's a good workout for the chest, stomach and face muscles. When you laugh hard, your leg and arm muscles get a good workout. When things do go wrong, look for the humor in the situation.
