“These findings help explain why swearing is so commonplace,” said Stephens. “Swearing is literally a calorie-neutral, drug-free, low-cost, readily available tool at our disposal for when we need a boost in performance.” The team next plans to explore the influence of swearing on public speaking and romantic behaviors, since these are situations where most people are more hesitant and less confident in themselves, and hence more likely to hold back.

If you’re human, you’ve probably hollered a curse word or two (or three) when barking your shin on a table edge or hitting your thumb with a hammer. Perhaps you’ve noticed that this seems to lessen your pain. There’s a growing body of scientific evidence that this is indeed the case. The technical term is the “hypoalgesic effect of swearing.” Cursing can also improve physical strength and endurance, according to a new paper published in the journal American Psychologist.

As previously reported, co-author Richard Stephens, a psychologist at Keele, became interested in studying the potential benefits of profanity after noting his wife’s “unsavory language” while giving birth and wondered if profanity really could help alleviate pain. “Swearing is such a common response to pain. There has to be an underlying reason why we do it,” Stephens told Scientific American after publishing a 2009 study that was awarded the 2010 Ig Nobel Peace Prize.
