not enough oxygen is getting into your body
Yawning is the body's tendency to get oxygen as fast as possible if your breathing does not supply your body enough. If you yawn too much, it means you are not getting enough oxygen through inhaling. Better consult a doctor for that. (:
When we are sleepy or drowsy then our lungs don't take enough oxygen which increases carbon dioxide in our body. The brain senses this and sends us a messages that causes us to yawn. By Akhilesh Sharma
We yawn because when we breath through our mouths it brings in more oxygen than when we breath in through our noses. ( which is what most people do.) Sometimes, our brain doesn't think that its getting enough oxgen so it makes you yawn. Try yawning now - feel how much oxgen comes into your mouth? That's why.
yawns are contagious becuase when we see another person yawn our brain sees it as that person is gasping for air and they dont have enough oxygen so as a defense mechenisme we will yawn also.

People yawn when their brain isn't getting enough oxygen. If you not breathing properly and not getting enough air while singing, you will yawn. If this is an annoyance to you, practice proper breathing techniques for singers. You can find them anywhere online.

You yawn.
When you are tired your body stops taking in enough oxygen, you yawn to compensate. As such when you see others yawn it alerts your body to the need of more oxygen, so you do too.

You're not getting enough sleep at night !
Human beings die in a few minutes if they are not able to breathe, or are deprived of oxygen. If you should find yourself in such a situation, obviously you should attempt to escape from it. Failing that, you will die.
