For a good yawn I need to really open my mouth and push/strain my jaw muscles. If that doesnt happen, then the yawn feels incomplete to my body and it happens again and again till it works “right”
What is the reason/body function behind that?

I always thought of it like, we’re all comfy and safe social signal. It makes you feel a bit sleepy as well, and it’s contagious because it makes other people want to return the signal. That’s just my theory though. A personal theory!
