Swearing helps you endure pain, says a study by Keele University. Based on tests, people who swear are able to withstand pain for a longer period of time than those who hold their tongue. Why? Swearing - if you don't use that language in ordinary speech - increases your fight-or-flight response, which allows you to tolerate pain in order to do what you have to to protect yourself.
However, if you use swear words in everyday language, they lose that adrenaline producing effect.
