Humor boosts the immune system
Whenever I prick myself accidentally, I tell a joke, and my finger doesn’t bleed! Well, not exactly. But if you are laid up in bed with a terrible strain of the flu that your four-year-old brought home from her play date yesterday, try to find an itsy-bitsy thread of humor in your situation, and you’ll be back to work in no time. Or, better yet, dwell in the misery and stay away from the cubicle longer.
In 2006 researchers led by Lee Berk and Stanley A. Tan at Loma Linda University in Loma Linda, Califormia, 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.
In his “American Fitness” article, Dave 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.
