The next time you smash your finger or stub your toe, try uttering a few expletives. Researchers from the U.K.’s Keele University have found that using a few “colorful metaphors” when genuine pain strikes can go a long way in easing your agony, especially if you don’t do it on a regular basis. In fact, for those who reserve swearing for only the most extreme circumstances, the act was found to be four times more effective than for those who regularly let profanity rip. Lead researcher Dr. Richard Stephens said the results of the analysis show that swearing can release pain-killing endorphins. He explains that “swearing provokes an emotional response in the face of stress akin to the flight and fight response” in an individual, which is how the body reacts to a perceived threat or danger.
