Why do you get physically weak when you laugh real hard?

Question

I noticed if I lost a great deal of my strength when lifting weights when someone made me laugh. why is that?

Answer 1

Mostly, when you laugh, you have irregular breathing. You are breathing totally out of whack while laughing, so for something like exercise, which requires a paced breathing, it throws you off. Also, laughing does require many of your muscles.

Answer 2

because ur breathing is different and it is cutting off some of the oxygen going to ur brain
