Saying swear words actually stresses your brain
From the page: “While there’s nothing quite like reeling off a string of profanities to blow off some steam, our brains might not agree with that sentiment. Saying swear words out loud actually triggers reactions deep in the emotion centers of the brain.
That’s the finding of Professor Jeffrey Bowers and Dr. Christopher Pleydell-Pearce, both of the University of Bristol’s School of Experimental Psychology. They designed an experiment in which participants read from three lists: one with swear words on it, another with euphemisms for those swear words, and finally a list of neutral words with no profane connections. The test subjects consistently had a far greater autonomic response when reading the actual swears – in other words, swearing was more stressful than not swearing, neurologically speaking.”
