Why We Yawn

Yawning doesn't just mean you're tired.
Yawning

Next time you're with a group of your friends, try this out. Take a big yawn, don't forget to cover your mouth, and wait to see how many other people yawn. There's a good chance your yawn will be contagious. In fact, before you even finish reading this story it is likely that you'll yawn at least once. Not that I'm trying to bore you, but just reading about yawning will make you yawn.

Yawning doesn't always mean you are bored. Adelie penguins actually yawn as part of their wooing ritual. Couples face each other and the males stand with their beaks wide open and face towards the sky.

As for why people yawn... good question. Nobody really knows why we yawn. For a while scientists believed that you yawned when there was too much carbon dioxide and not enough oxygen in your blood. Part of your brain realized this and triggered you to yawn. As your mouth stretches you inhale deeply, sending a shot of oxygen to the lungs and into the bloodstream. That theory went out the window because nobody can prove it.

The reason yawns are contagious? Power of suggestion perhaps. If you're out late with your friends after school, you're probably tired. You're probably on the verge of a yawn, too, and seeing one person do it is enough to drive everyone to yawns.

Have I made you yawn yet? If I have, I hope it's not cuz you're bored, but simply by the power of suggestion.

Ello and I am sorry your going through all this pain. Your  being strong for everyone else trying to put on the happy smiley face and at the same time your feeling so miserables.  You said in your post that you already does go to the type of therapy.  Is there any way you can talk to someone at the therapy sessions and say you need to talk about this? Sometimes you has to say you has the problem cos right now your giving the signal that your ok cos your hiding your feelings. Im the horrible advise giver but im the good friend and i care and if you wanna comment me then i will do me best to be your friend and listen :love
