How Swearing Helps Relieve Pain

Why a Four-Letter Word Might Be a Five-Star Painkiller

Yes, it’s true! Swearing has been scientifically shown to help relieve physical pain—at least temporarily.

In a widely cited study from Keele University in the UK, researchers asked volunteers to submerge their hands in icy cold water for as long as they could stand it. Some were told to repeat a neutral word, while others were encouraged to let loose with a swear word.

The result?

Those who swore were able to withstand the pain up to 50% longer on average.

Why does it work? According to scientists, swearing triggers a mild fight-or-flight response—a surge of adrenaline that temporarily boosts pain tolerance. It also provides an emotional release that can reduce the sensation of pain and even help us stay calmer in distressing moments.

A few fun details:

• The effect seems to work best when the swear word is emotionally charged and not used too frequently in everyday speech.

• The pain-relief boost is short-term, but real.

• Swearing may also boost confidence and resilience during stressful situations, such as workouts or medical procedures.

So yes—when used sparingly, a well-timed curse can do more than express frustration. It might just help you tough it out!
