Research led by Swiss neuroscientist Pascal Vrticka and his U.S. colleagues at Stanford University has found that, among other things, humor plays a key role in psychological health. According to the study, recently published in the journal Nature Reviews Neuroscience, adults with psychological disorders such as autism or depression often have a modified humor processing activity and respond less evidently to humor than people who do not have these disorders. Vrticka believes that a better understanding how the brain processes humor could lead to the development of new treatments.
This is not the first study to explore the healing force of humor. In 2006 researchers led by Lee Berk and Stanley A. Tan at Loma Linda University in Loma Linda, California, found that two hormones — beta-endorphins (which alleviate depression) and human growth hormone (HGH, which helps with immunity) — increased by 27 and 87 percent respectively when volunteers anticipated watching a humorous video. Simply anticipating laughter boosted health-protecting hormones and chemicals.
The same research team conducted a similar study recently to see if the anticipation of laughter that was shown to boost immune systems could also reduce the levels of three stress hormones: cortisol (“the stress hormone”), epinephrine (adrenaline), and dopac, a dopamine catabolite (brain chemical which helps produce epinephrine).
They studied 16 fasting males, who were assigned to either the control group or the experiment group (those anticipating a humorous event). Blood levels showed that the stress hormones were reduced 39, 70, and 38 percent respectively. Therefore, researchers suggest that anticipating a positive event can reduce detrimental stress hormones.
“Humor rooms,” which encourage people to use humor in their recovery from any kind of illness, are now available in some hospitals. And science backs these efforts.
In a study published in the Journal of Holistic Nursing, humor very definitely seemed to diminish pain. Says Dave Traynor, M.Ed, director of health education at Natchaug Hospital in Mansfield Center, Connecticut in “American Fitness”: “After surgery, patients were told one-liners prior to administration of potentially painful medication. The patients exposed to humor perceived less pain as compared to patients who didn’t receive humor stimuli.”
Traynor explains a separate study at Arkansas Tech University, in which concentrations of immunoglobulin A were increased after 21 fifth graders participated in a humor program. (I’m nervous to hear about the details of that fifth-grade humor program, because my kids roar whenever you throw out a bathroom term.) Laughter was once again found to increase the ability to fight viruses and foreign cells.
American journalist Norman Cousins is famous for using humor to cure himself from a painful kind of arthritis then called Marie-Strumpell’s disease. His recovery program, detailed in his book “Anatomy of An Illness,” included massive doses of Vitamin C and laughter induced by the Marx Brothers films.
“I made the joyous discovery that ten minutes of genuine belly laughter had an anesthetic effect and would give me at least two hours of pain-free sleep,” he reported. “When the pain-killing effect of the laughter wore off, we would switch on the motion picture projector again and not infrequently, it would lead to another pain-free interval.”
