Researchers discovered that repeating curse words during intense physical tasks can improve performance by 2.5 to 3 seconds. Lead author Richard Stephens of Keele University tested 182 adults doing chair push-ups while saying either swear words or neutral words. Published in American Psychologist, the study showed participants held positions for 26.92 seconds when swearing versus 24.19 seconds with neutral words. “In many situations, people hold themselves back – consciously or unconsciously – from using their full strength,” Stephens said. “Swearing is an easily available way to help yourself feel focused, confident and less distracted, and ‘go for it’ a little more.” The effect works through increased flow state, distraction from discomfort, and heightened self-confidence rather than adrenaline, suggesting profanity temporarily releases mental brakes that limit physical effort.
