In an experiment done at an English university, 64 students held their hands in ice water for as long as they could while repeating a swear word of their choice. The same students also held their hands in ice water for as long as they could while repeating a neutral word. For each condition, the researchers measured pain tolerance, the length of time of submersion, and physiological responses such as heart rate. The result was that the students had better pain response while swearing (Stephens et al., 2009).
