Why are yawns contagious? Like why when someone yawns or you think about it you automatically have to yawn?
Also why, when you yawn, does it make your eyes water?
Thanks!

not sure why they are contagious but i do know that when you yawn it means you have a lack of oxygen to the brain.

Why are you wasting everybody time asking such idiotic question?
