Laughter And Cardiovascular Health

By: Rick London
 

Laughter being good medicine sounds cliche, of course. It may, or may not be the best, but modern medicine now knows it is very good for you. If not the best, certainly close to it...at least for your heart. Research shows that mental stress can restrict blood flow to the heart. But now a study has linked laughter to increased blood circulation. Laughter appears to cause the tissue inside blood vessels to expand. Medical science feels that laughter may be important to enhance the health of your heart.

The University of Md. recently conducted a study of twenty healthy adult males and females. To make them laugh, they watched part of the movie "Kingpin," a 1 hour comedy. To create the opposite emotions, they also watched the "Saving Private Ryan, dramatic war scene at the beginning of the movie.

Researchers used ultrasound technology to measure changes in blood flow through an artery in the arms of participants. Blood flow increased in 19 of the 20 participants after watching "Kingpin." which is a 22% increase. The study leader, a Dr. Miller feels that is similar to the effects of aerobics. Blood flow decreased in 14of the twenty people after they watched "Saving Private Ryan." The decrease was an average of thirty-five percent.

One can reduce disease when reducing stress according to studies. When the body is under stress, it produces hormones such as adrenalin and cortisol. Cortisol is related to fear and adrenalin gives us us the "fight or flight feeling". Too much of these hormones can be harmful. Dr Miller observed that the study could not explain how laughter is responsible for the effects observed. He could not decipher if it had to do with chemicals or muscles.

Clinical studies have shown laughter may cause the body to release endorphins, like when exercise takes place. Miller states that these endorphins may block the effect of stress hormones and cause the blood vessels to expand. Laughing may also influence the release of nitric oxide, which too expands blood passages. The results were presented at a meeting of the American College of Cardiology. Dr. Miller does not suggest to replace exercise with laughter, but he says just a quarter hour of laughter could absolutely make one healthier, not to mention happier.
