Actually there's really nothing "new" about this study at all...and to be honest, it kind of sounds like common sense to me anyway!
Reports the Telegraph:
Scientists from Keele University found that letting forth a volley of foul language can have a powerful painkilling effect, especially for people who do not normally use expletives. To test the theory, student volunteers placed their hands in a bucket of ice cold water while swearing repeatedly.
Researchers found that the students were able to keep their hands submerged in the icy water for longer when repeating the swear word – establishing a link between swearing and an increase in pain tolerance. The research proves that swearing triggers not only an emotional response, but a physical one too, which may explain why the centuries-old practice of cursing developed and why it still persists today.
