hehe and i have proof

It has been shown that laughing helps protect the heart. Although studies are inconclusive as to why, they do explain that mental stress impairs the endothelium, the protective barrier lining a person’s blood vessels. Once the endothelium is impaired, it can cause a series of inflammatory reactions that lead to cholesterol buildup in a person’s coronary arteries. This can ultimately cause a heart attack. Psychologist Steve Sultanoff, Ph.D., the president of the American Association for Therapeutic Humor, gave this explanation:

"With deep, heartfelt laughter, it appears that serum cortisol, which is a hormone that is secreted when we’re under stress, is decreased. So when you’re having a stress reaction, if you laugh, apparently the cortisol that has been released during the stress reaction is reduced."

Also according to Sultanoff in his interview for the article for WebMD, laughter has been shown to increase tolerance of pain and boost the body’s production of infection-fighting antibodies, which can help prevent hardening of the arteries and subsequent conditions caused thereby such as angina, heart attacks, or strokes.

Sultanoff also added that research shows that distressing emotions lead to heart disease. It is shown that people who are “chronically angry and hostile have a greater likelihood for heart attack, people who “live in anxious, stressed out lifestyles have greater blockages of their coronary arteries”, and people who are “chronically depressed have a two times greater chance of heart disease.” WebMD 2000

[edit] Diabetes

A study in Japan shows that laughter lowers blood sugar after a meal. Keiko Hayashi, Ph.D., R.N, of the University of Tsukuba in Ibaraki, Japan, and his team performed a study of 19 people with type 2 diabetes. They collected the patients’ blood before and two hours after a meal. The patients attended a boring 40 minute lecture after dinner on the first night of the study. On the second night, the patients attended a 40 minute comedy show. The patients’ blood sugar went up after the comedy show, but much less than it did after the lecture. The study found that even when patients without diabetes did the same testing, a similar result was found. Scientists conclude that laughter is good for people with diabetes. They suggest that ‘chemical messengers made during laughter may help the body compensate for the disease.” WebMD 2003

[edit] Blood flow

Studies at the University of Maryland found that when a group of people were shown a comedy, after the screening their blood vessels performed normally, whereas when they watched a drama, after the screening their blood vessels tended to tense up and restricted the blood flow. WebMD 2006

[edit] Immune response

Studies show stress decreases the immune system. “Some studies have shown that humor may raise infection-fighting antibodies in the body and boost the levels of immune cells.” Web MD 2006“When we laugh, natural killer cells which destroy tumors and viruses increase, along with Gamma-interferon (a disease-fighting protein), T cells (important for our immune system) and B cells (which make disease-fighting antibodies). As well as lowering blood pressure, laughter increases oxygen in the blood, which also encourages healing.” Discover Health 2004

[edit] Anxiety & children

According to an article of WebMD, studies have shown that children who have a clown present prior to surgery along with their parents and medical staff had less anxiety than children who just had their parents and medical staff present. High levels of anxiety prior to surgery leads to a higher risk of complications following surgeries in children. According to researchers, about 60% of children suffer from anxiety before surgery.

The study involved 40 children ages 5 to 12 who were about to have minor surgery. Half had a clown present in addition to their parents and medical staff, the other half only had their parents and medical staff present. The results of the study showed that the children who had a clown present had significantly less pre-surgery anxiety.WebMD 2005

[edit] Relaxation & sleep

“The focus on the benefits of laughter really began with Norman Cousin’s memoir, Anatomy of an Illness. Cousins, who was diagnosed with ankylosing spondylitis, a painful spine condition, found that a diet of comedies, like Marx Brothers films and episodes of Candid Camera, helped him feel better. He said that ten minutes of laughter allowed him two hours of pain-free sleep.” WebMD 2006

[edit] Physical fitness

It has been estimated by scientists that laughing 100 times equals the same physical exertion as a 10 minute workout on a rowing machine or 15 minutes on a stationary exercise bike. Laughing works out the diaphragm, abdominal, respiratory, facial, leg, and back muscles. Cool Quiz 2006

However, William Fry, a pioneer on laughter research, in an article for WebMd was said to indicate that it “took ten minutes on a rowing machine for his heart rate to reach the level it would after just one minute of hearty laughter.” WebMD 2006

[edit] Asthma

Nearly 2/3 of people with asthma reported having asthma attacks that were triggered by laughter, according to a study presented at the American Thoracic Society annual meeting in 2005. It did not seem to matter how deep of a laugh the laughter entailed, whether it be a giggle, chuckle, or belly laugh, says Stuart Garay, M.D., clinical professor of medicine at New York University Medical Center in New York.

Patients were part of an 18 month long program who were evaluated for a list of asthma triggers. The patients did not have any major differences in age, duration of asthma, or family history of asthma. However, exercise-induced asthma was more frequently found in patients who also had laughter-induced asthma, according to the study. 61% of laughter induced asthma also reported exercise as a trigger, as opposed to only 35% without laughter-induced asthma. Andrew Ries, M.D. indicates that “it probably involves both movements in the airways as well as an emotional reaction.” WebMD 2005

[edit] Strengthening muscles

In addition to helping in many other ways, laughing is also clinically proven to strengthen the abdomen. Jared B. Cohen, Ph.D has run many experiments on laughing at his laboratory in Newark, New Jersey and says "Laughing not only helps your heart, but it also helps you look good for the beach". Although some think it is impossible that something as simple and painless as laughing can strengthen ones abdomens, 14 out of every 15 of Cohen's patients said that laughing was a better, and more humorous workout than sit-ups or crunches. To make laughing a truly effective workout, one must laugh for at least 30 seconds until they feel a small burning sensation. Although laughing is a fun way to workout, it is still advised, that whenever possible, one does sit-ups or crunches instead.^{[citation needed]}
