You may think the old saying “Laughter is the best medicine” is a joke, but science proves it’s not. Want a quick and easy way to beat stress? Researchers at the University Maryland School of Medicine say the healing power of laughter is real. Researchers have found when you laugh, it opens up your blood vessels, causing less stress on your heart. And it can also de-stress the rest of the body by releasing endorphins from the brain. In fact, research shows that 15 minutes a day of laughter, real deep belly laughter is as important for your heart as 30 minutes of exercise 3 times a week.
