If you need help pushing through your workout, go ahead and swear.

According to researchers at Keele University in England, swearing works to support your stress response when working out. They say the resulting flush of adrenaline triggers your fight or flight response.

Researchers say this boosts your heart rate and oxygen intake. They say swearing helps the body combat pain.

However, researchers caution that curse words seem to lose their power over pain when they are used too much.
