According to scientists from Keele University
swearing can be a powerful
Scientists asked a group of 71 students to dip their hands into ice-cold water and hold it for as long as they can, while swearing non-stop. After that the under-graduates were asked to repeat a similar exercise, but keep their language clean. When the volunteers uttered a swear word they were able to hold their hands in the water for a longer time which proved that humans have greater pain endurance if they swear. Swearing was 4 times more likely to ease the pain caused by the icy water.
The research team believes that swearing triggers release of pain-killing endorphins.
