Laughter Really Is Good Medicine
The group met for 45 minutes. The leader took them through stretching exercises, yoga breathing and exercises in which they did different types of laughter. "In the beginning, you fake it," Danzger says. As the exercises progressed, "it induced real laughter." The session finished with a few minutes of quiet meditation.
"Everyone was so happy at the end," says Danzger. "The laughter gets so much stuff out of your head...and gets you to a very peaceful, serene place."
The group held two sessions, and Danzger hopes to do more on her own. "It's a very freeing, joyous experience," she says.
Faking it helps make it
There's a difference, Bennett notes, between humor (a mental process) and outright laughing, a physical activity that triggers physiological reactions.
In one study, Bennett and her colleagues measured whether watching a funny video would affect the immune systems of a group of adult women. While stress levels went down for the group, "only the people who physically laughed out loud had an increase in natural-killer (NK) cell activity," she says. NK cells are frontline responders in the body's immune system. Low NK cell activity makes you more susceptible to disease and puts people with cancer or HIV at greater risk of death.
"If you're getting a good belly laugh every few minutes, you're improving your immune function," Bennett says.
Although humor and laughter are two separate things, laughing because you think something is funny and learned laughter—such as Danzger practiced in her group sessions—both cause the same positive physical responses.
So why should you learn how to laugh when you've been laughing naturally all your life?
First, because humor—especially belly-laugh-producing humor—isn't the same for everyone. Consider the range of what makes people laugh: scan the cable TV channels and you're likely to see one or two programs that cause you to chuckle out loud at least once. There are probably many more shows that you don't find funny at all, yet millions of people watch those programs and laugh heartily.
What's more, humor can't always be summoned on demand. When you're depressed, worried, sad or stressed out, humorous entertainment or conversation might not make you guffaw.
"Humor is so dependent upon our culture and our mood at the moment," says Judy L. Young, a laughter coach and educator in Wichita, KS, who coauthored a study of "purposeful aerobic laughter"—or laughter without humor. "We teach you how to laugh on your own, which is very helpful when people are in a place in life where they have nothing to laugh about."
