From birth, we instinctively yelp whenever we are hurt. Now, scientists from the National University of Singapore say there is a reason behind our spontaneous groans as being vocal helps us tolerate pain.
In a study, 56 people were asked to immerse their hands in painfully cold water. Those who uttered the word 'ow' were able to stand the pain for up to three-and-a-half minutes longer. One theory is that the muscle movements involved in making such an exclamation interfere with the pain messages travelling to the brain.
