If you sit in front of a computer most of the day, work in a high stress environment, and battle high blood pressure, throw your head back and laugh. Seriously, scientists are exploring the positive effects of laughter on these and other conditions impacting our health and wellbeing. Good hearted hilarity provokes the body to shake and gesture especially in the area of the abdomen. (I wonder if this is what they mean by belly laugh.) The resulting endorphins will melt away the pounds. Obviously you have to do it for 20 minutes or more, but this is my kind of exercise.
In addition, consistent chuckling increases the production of cortisol, a hormone to help the body defend itself against stress. Some studies have found that laughter actually improves your immune system and helps you fight disease.
You can even overcome fear by countering it with an enthusiastic case of the giggles. If you have any doubts, check out how this baby does it.
