We change physiologically when we laugh. We stretch muscles throughout our face and body, our pulse and blood pressure go up, and we breathe faster, sending more oxygen to our tissues. People who believe in the benefits of laughter say it can be like a mild workout -- and may offer some of the same advantages as a workout."The effects of laughter and exercise are very similar," says Wilson. "Combining laughter and movement, like waving your arms, is a great way to boost your heart rate." And laughter appears to burn calories, too. 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. While the results are intriguing, don't be too hasty in ditching that treadmill. One piece of chocolate has about 50 calories; at the rate of 50 calories per hour, losing one pound would require about 12 hours of concentrated laughter!
Laughter helps plenty parts of our Body, some of this are;
Blood flow. Researchers at the University of Maryland studied the effects on blood vessels when people were shown either comedies or dramas. After the screening, the blood vessels of the group who watched the comedy behaved normally -- expanding and contracting easily. But the blood vessels in people who watched the drama tended to tense up, restricting blood flow.
Immune response. Increased stress is associated with decreased immune system response, says Provine. Some studies have shown that the ability to use humor may raise the level of infection-fighting antibodies in the body and boost the levels of immune cells, as well.
Blood sugar levels. One study of 19 people with diabetes looked at the effects of laughter on blood sugar levels. After eating, the group attended a tedious lecture. On the next day, the group ate the same meal and
