A good belly laugh allows you to exercise your diaphragm, contracts your abs and even works out the shoulders, leaving your muscles more relaxed. Laughter can provide a good workout for your heart and its aerobic effects help increase your body’s ability to use oxygen.

Research has shown health benefits of laughter ranging from strengthening the immune system to reducing food cravings to increasing one’s threshold for pain.  There’s even an emerging therapeutic field known as humor therapy to help people heal more quickly, among other things.  Humor also has several important stress relieving benefits.

Laughter also appears to burn calories. Maciej Buchowski, a researcher from Vanderbilt University, conducted a small study in which he measured the amount of calories expended in laughing. It turned out that 10-15 minutes of laughter burned 50 calories.

A person that can laugh things off has a more positive outlook on life events and provides you with a different perspective and helps you get through rough times.
