The more you curse when you hurt yourself, the better you feel.

Two U.K. researchers have done several studies to find the correlation between swearing and pain. 

Olly Robertson and Richard Stephens discovered that people who used a “conventional” swear word had a “32% increase in pain threshold and a 33% increase in pain tolerance.”

Stephens said cursing when hurt mimics the “fight or flight” bodily stress response, which occurs when the heart rate goes up and adrenaline surges into a person’s muscles when an action needs to be taken.  

Samford University professor Nick Washmuth added, “The f-word is the most commonly self-selected swear word by participants in these studies and is considered one of the most powerful swear words out there.”
