Once upon a time, Charlie Chaplin said, "Laughter is the tonic, the relief, the surcease for pain." Last week, The New York Times agreed. The reported on a recent study which found that,"laughing increased pain resistance." In this story, the science of modern times sides with the clown. The Oxford study also suggests that laughter has provided primates with an age-old evolutionary advantage.
Oxford evolutionary psychologist Robin Dunbar concluded that laughter triggers endorphins that allowed test subjects to resist pain longer. Test subjects watched a variety of video. Some subjects watched "The Simpsons," Eddie Izzard routines, and other comedy clips. Other participants watched footage considered feel-good without being funny, like nature programs. Others were subjected to boring- er- 'neutral' golf and pet training videos. All participants were monitored for laughter during the shows. The participants who laughed proved better able to withstand pain resistance tests adminstered after watching the videos. Another experiment, conducted live at an Oxford Imps improv show, supported the findings that laughter eases pain.
The study reports that laughter, not just a general sense of well being, is key to the endorphin response and pain relief. Dr. Dunbar hypothesizes that laughter has been key to the social evolution of primates. Like singing, dancing, and other physical activities, shared laughter strengthens group bonds. A laugh today may play tonic to your pain, and shared giggling echoes age-old evolutionary rewards. I think may be time to rewatch Charlie Chaplin...
Dunbar's study was published in the proceedings of the Royal Society B, Biological Sciences.
