If you’ve already slipped on the ice this winter, good news: science says your first word was the right one. A new research review finds that swearing can improve physical performance in short, intense bursts — increasing strength, pain tolerance, and endurance. Studies show that when people do tasks like gripping something really hard, pushing to fatigue, or trying to get skis back on after a fall, swearing can boost power by up to 9% and endurance by more than 20%. Scientists aren’t sure of the exact mechanism, but theories include activating a fight-or-flight response, raising pain thresholds, or simply unlocking the emotional energy that comes with a cold-weather wipeout.
