Many of us find joy in liberally using profanity. Why? Because it feels satisfying. Recent scientific findings have validated this common behavior, thanks to a new study conducted by researchers at Keele University in the UK.

The research indicates that swearing can enhance physical performance and lead to better results in strength and endurance tests.

According to Dr. Richard Stevens, who spearheaded the study: BBC Science Focus, “This study essentially confirms what we consider common sense: swearing when we need to can elevate our mood.” He described swearing as a “low-cost, easily accessible, non-drug self-help strategy.”

To explore this phenomenon, the research team performed two experiments involving 192 participants. During the first experiment, each volunteer shouted an expletive every two seconds while doing push-ups (raising their body using only their arms) on a chair.

Participants also completed the same task using neutral words instead. Some began with swearing, while others started with neutral terms.

The results were significant. Those who swore were able to maintain their weight support for longer periods.

Stevens attributes this enhancement in performance to people feeling less constrained when they swear. “You become more uninhibited, you push past your hesitations and go all out instead of holding back,” he explains.

This effect was later confirmed through a post-test questionnaire, showing that participants reported higher levels of “psychological flow” when swearing—a state where they were fully engaged and enjoying the activity.

“This paper builds on research from the 1960s indicating that shouting, loud sounds, alcohol, and similar stimuli enhance physical performance. It suggests that reducing inhibitions can boost fitness,” Stevens remarked.

But what is it about profanity that gives it such power? Stevens posits that it “must relate to their taboo nature.” He noted that many curse words are “double taboos,” meaning they aren’t just socially unacceptable, but often touch on other sensitive subjects, such as sex.

The research team plans to delve deeper into the influence of a word’s taboo nature by examining its effects on pain tolerance. Essentially, they’re searching for the ultimate swear word with the greatest impact.

For now, you might be wondering if you should incorporate more swearing into your life. According to science, the answer is affirmative.

“Our findings indicate that swearing diminishes inhibition and enhances performance, suggesting that this effect may extend to other scenarios where success relies on overcoming hesitation,” Stevens stated.

“Using curse words strategically during challenging moments, especially when we’re outside our comfort zone, can help us unlock our full potential and ultimately achieve greater success.”
