Yawning helps you get more oxigen to the brain.
Most likely because you're tired or really, really bored. Have you ever noticed yourself yawning at those times? It's usually because you start to breathe slowly when you're tired or bored, and not enough oxygen gets to the brain. So, the best way to get that air, is to take a deep breath, which is known commonly as a yawn.
As per the theory of yawning, when the person gets tired or bored, the amount of carbon di oxide in the body of person increases and oxygen level decreases. This leads to low blood flow to the heart and brain, so to increase the oxygen level the person yawns. In the process of yawning more amount of carbon di oxide goes out of the body and the body can take more amount of oxygen
because fleas can jump 20? ...... give or take :)
It isn't because you are tired, it is because your blood lacks oxygen. When you've been idle too long and suddenly move, you can find yourself yawning later on. That's why a person yawns after waking up in the morning. Yawning adds oxygen to the blood. If it bothers you, try deep breathing.
Because you're tired.
it means either you are bored or they are tired
None ! Yawning is either the body signalling you're tired, or that you're short of oxygen. Nothing to do with muscles !
Yawning helps you get more oxigen to the brain.

Um, I shouldn't think that yawning itself causes heart palpitations, but if you are extremely tired, there is more chance of you having a palpitation.
They will feel dizzy. Weak. Tired and they will keep yawning.
You can't stop yawning because when you yawn your body is trying to get more oxygen into you body to try and stay awake. If you are yawning constantly your body is trying to keep you awake, the longer you stay awake, the more you will yawn.
Yawning too much can prove to be fatal. My aunt didn't sleep for a week, kept yawning, and died. You're in trouble
Well, it isn't good or bad. It is just something you're body does naturally when it's tired. You yawn because when you are tired, you don't have as much oxygen as you normally do.
Technically, no it doesn't. it's one of the bodies natural reactions to a buildup of CO2 in the body
