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...
1 yawn means you are tired. 2 yawns means you need a nap. 3 yawns means you need to go to sleep.
I don't know about "drowsy" but I have heard that if someone near you yawns, you yawn too. Like yawns are contagious. Yawns don't mean that you're tired. It also means that you're not getting enough oxygen, but that has not been scientifically tested.
Actually that is a lie. Yawns are contagious.
"He Who Yawns" was the actual name of Geronimo (Goyahkla), leader of the Apache band in Arizona.
