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?

People doing cardio and people exposed to elevated co2 don’t yawn, yet dogs yawn when they see people yawning so its probably not that simple.
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!
I mean, when I see videos of animals yawning, like lions, I get the urge myself to yawn. So definitely a complex topic.
