Laughter: The Best Medicine?

 

e-Medical Note:

Is Laughter Really the Best Medicine?

Though it has long been axiomatic that laughter is the best medicine, it may now be scientific too. Research shows that laughter: 

  • Boosts the immune system
  • Increases the level of pain-killing chemicals in the brain
  • Provides a beneficial "workout" for the lungs, heart, chest and abdomen.

Laboratory studies have demonstrated that the levels of a kind of antibody known as IgA, found in saliva and in the mucous membranes of the lungs and intestinal track, measurably increase during laughter [Western New England College - Springfield, Massachusett]. 

The IgA antibody is known to lower a person's susceptibility to upper respiratory illness. Researchers also found that among the study subjects, the levels of this antibody were already higher in those who laugh with greater regularity and rely on humor to relieve stressful situations.

Laughter also aids in the functioning of the immune system by stimulating the release of interleukins - hormones that block the release of the hormone cortisol. When under stress or in physical danger, the body secretes cortisol to allow quick action and reaction but high levels of cortisol in the cells act as an immuno-suppressant, diminishing the body's ability to fight disease and infection.

Research has shown that a bout of laughter triggers the release of a flood of beta endorphins, a morphine-like compound in the brain that can induce a sense of euphoria while blocking pain. Beta endorphins are one of the body's best natural painkillers. In his book Anatomy of an Illness, Norman Cousins describes how 10 minutes of laughter had allowed him two hours of pain-free sleep at a time when his body was fighting a painful degenerative disease. Laughter had accomplished what medication could not.
