Same thing as when you yawn..... When you get tired you get a shortness of breath causing you to yawn...you yawn to catch your breath when your tired...
When you yawn it doesn't mean your sleepy. Even scientists don't know why you yawn.
We yawn because We yawn because we need to get rid of CO2, so that would mean if you don't yawn you will eventually die from hypercapnia (too much CO2)!
There are two answers.If you mean you can't hear yourself yawn, then it could mean you aren't yawning loud enough to hear it or you can't hear very well.If you mean you can't hear anything when you yawn, then that could be a problem or a sign of poor hearing. Everybody is different but when I yawn, I can hear stuff around me. Good luck and I Hope this helps =]
no it means you have rectal disfunction
