In a nation that spent some 75 million dollars on prescription drugs in 1993, not to mention illegal drugs, we sometimes overlook the coping mechanisims we have been endowed with (U.S. 1995). Our bodies were created to take care of themselves for the most part, and we sometimes botch things up when we try to alter our system with drugs. In Proverbs 17:22 (1989), it says “A merry heart doeth good like a medicine, but a broken spirit drieth the bones.” For many years scientists and lay persons have done studies, research, and performed experiments concerning the effects of laughter on ones physical and mental health. These studies have proven that when we laugh, there is an actual chemical change in our bodies that helps to ease pain and release stress. Laughter is a coping mechanisim for the normal stress of life.
There are two kinds of stress–distress, which is the negative kind of stress; and eustress, which is the positive kind of stress. While distress increases stress hormones such as beta-endorphin, corticotrophin, cortisol, growth hormone, prolactin, and the catecholamines, eustress decreases these hormones and instead increases the activity of Natural Killer (NK) cells that help fight diseases (Berk & Tan 1996). Distressful events and major life changes can obviously impact our bodies negatively. It has been proven that stress depletes the immune systems ability to fight against disease. Dr. Lee Berk and Dr. Stanley Tan of the Loma Linda University Medical Center have done an abundance of research in psychoneuroimmunology (PNI). PNI simply says that the immune system is directly connected to the brain; therefore, it would be effected by the emotions. One of Berk and Tans experiments showed that immunosuppressive hormones (hormones that harm or deplete the immune system) such as epinephrine and cortisol were lower in those participants that laughed than in those who did not (Wooten 1995). Another experiment performed by Berk and Tan (1996) in which they presented their results at a conference on April 18, 1996, proved that laughing (while watching a humorous video) increases the amount of NK cells.
Indirectly, stress is probably our number one killer. It effects us physically and mentally, wearing our immune systems down, and causing us to be more susceptible to sickness and disease. We try to treat the disease, when we really need to treat the cause. How does one treat something like stress? Many times the stressors cannot be removed from a persons life; they are permanent fixtures. Laughter, if used generously, can help drain the stress away. As Mark Twain once said, “The human race has only one really effective weapon, and thats laughter. The moment it arises, all our hardnesses yield, all our irritations and resentments slip away, and a sunny spirit takes their place.”
What is laughter? Laughter is a form of eustress that releases those bad and distressful emotions that cause harmful chemical effects on the body (Berk & Tan 1996). Laughter is like an exercise; that is why your stomach sometimes feels sore after a good belly laugh. Just as in exercise, there are two stages to laughter: the arousal phase–when the heart rate increases–and the resolution phase–when the heart rests. A persons heart can reach up to 120 beats per minute (bpm) when laughing. Laughing can lower your blood pressure, increase vascular flow, and boost the immune system. It gives the diaphragm, abdominal, intercostal, respiratory accessory, and facial muscles a complete workout. Some people, depending on how they laugh, may even use their arm, leg, and back muscles when laughing. Laughter also releases endorphins in the brain; these are our bodies natural pain killers (Wooten 1995). Endorphins are neurotransmitters that attach to the same receptors in our brains as the opiates. Opiate drugs not only cause us to lose touch with reality, but they also numb pain. When we laugh, it releases the endorphins in our brain; thus, laughing is like taking opium or morphine without the adverse side effects (Kalat 1995).
In Berk and Tans (1996) experiment concerning the laughter immune connection, they used ten healthy fasting males who volunteered for the experiment, and had them view a one hour, funny video. They took blood samples of their interferon-gamma (IFN) before, during, and after they watched the tape. They had significant results that showed increased activity in IFN after watching the funny video and on into the following day. What is IFN? It activates the T cells, B cells, immunoglobulins, and NK cells; it helps to fight viruses, and regulate cell growth. This could be very important in the research for cancer since it also fights against tumorous cells.
Nearly 2000 years ago, the physician Galen stated that cheerful women were less likely to get cancer than those women who were depressed (Simonton 1978). John Steinbeck once said “A sad soul can kill you quicker, far quicker, than a germ.” Laughters ability to be a pain reliever and its ability to fight tumorous cells have added an exciting new area of research to cancer. Some of the research done by O. Carl Simonton, M.D. and Stephanie Matthews-Simonton (1978), leads us to believe that a persons emotional status does indeed effect their likelihood of getting or overcoming cancer. Perhaps, if people would start relieving their stress through laughter before they get cancer, there might be a reduction in the number of cancer patients altogether.
Norman Cousins (1979), the man who started the laughter health craze in this century, was editor of the Saturday Review for over thirty years, and has written numerous books including Anatomy of an Illness. In August 1964, Cousins came home from a meeting in Moscow with a fever and feeling achy all over. Within a week he could not move and his sedimentation rate was up to 88. The sedimenation rate relates to how much infection is in the body and a sed. rate of 60 to 70 is thought to be very high. He was eventually diagnosed with ankylosing spondylitis, which is a collagen illness that attacks the connective tissues of the body. He once said it felt as if he was being pulled apart at the joints. The doctors told him it was probably caused from exposure to heavy-metal poisoning, so he began to think of when he could have been exposed. The only thing he could remember was that his hotel in Moscow was next to a major highway where diesel trucks passed all night long, and since there was no air in the room, he had kept the windows open all the time. However, his wife was with him, and she did not become sick. He started reading material about stress and how it can wear down your immune system. He came across a book by Hans Selye called The Stress of Life that proposed the theory that negative
