More About Laughter

Here is more good news to smile about this year. A recent study found that groups that either watched or participated in comedy felt less pain than their peers, who watched a documentary. People who laughed more had an even higher pain threshold than those who only had a few giggles. Chuckling with others also increased laughter's positive impact. People are 30 times more likely to laugh in a group than alone.

Laughing triggers endorphins, neurotransmitters produced by the pituitary gland and hypothalamus, which spark a feeling of comfort similar to what occurs when someone takes an opiate. Love, excitement, spicy foods, orgasms, exercise, and pain all cause the brain to produce endorphins, which also provide an analgesic effect.
