Yawning
One theory of why we yawn is that when we are bored or tired, we just don't breathe as deeply as we usually do. As this theory goes, our bodies take in less oxygen because our breathing has slowed. Therefore, yawning helps us bring more oxygen into the blood and move more carbon dioxide out of the blood.

This made me realize that since I have been on CPAP, I don't yawn. Interesting.
It sounds like yawning is good for us to me.
True..... but I think some yawns could be from boredom haha!

Yawning is good for sleep.
