When people feel nervous, they tell jokes because it helps them feel better. It’s like when you’re scared of a monster and you start laughing, it makes the monster seem smaller. Jokes are like magictricks that help your brain say, 'I’m not as worried as I thought.'
Why Jokes Work
Jokes make people laugh, and laughter feels good. When you feel happy, being nervous doesn’t hurt as much. So telling jokes helps the brain forget about stress for a little while.
