Laughter Therapy Takes Off in South Korea

SEOUL, Korea, March 7, 2008 — -- An hour of weekly laughter was good enough for Jung-Oak Lee, 64, to fight off depression that coincided with two years of chemotherapy to treat her colon cancer.

Every Friday afternoon, she travels almost two hours to join about 100 other cancer patients and families in a packed hallway of Seoul National University Hospital, one of Korea's largest, to learn how to guffaw.

"It was awkward at first. Yes, smiling is a good thing, but you know, I'm a little conservative. I sometimes still think laughing out loud is a bit low class," she said.

In a country of Confucian tradition where solemnity is considered noble and jocularity the opposite, Koreans are usually taught to keep their emotions inward.

As the old Korean saying goes, men are not to cry more than thrice in their lifetime -- at birth, at loss of sovereignty of his country and at parent's death. And for a household to prosper, women's laughter should not be heard outside the fence of her home.

"The social culture is changing now, though. Laughing is considered positive, but many people still don't know how to let it out," said Lim-Sun Lee, a nurse and laughter therapist leading the session. "But all it takes is four sessions. After that, they start cracking up."

The hourlong session is a mixture of dancing, lectures, sharing jokes and show-and-tell confessions.

"Today, we're going to learn the penguin dance," Lee shouts, "so waddle around and stomp your feet to the music!" Mimicking and giggling, the groups of all ages from a 6-year-old to senior citizens wave their arms.

Most cancer patients have some period of mental depression and laughing has a significant therapeutic value, according to Lee.

Studies have shown that effects of laughter on the body start with blood vessels expanding, which stimulates circulation. After laughing, blood sugar levels drop and the action helps promote comfortable sleep. It also boosts the level of serotonin that provides calming actions in the brain and body, and the level of dopamine linked with feelings of happiness and pleasure.
