Yawning

[milly143]

Why do you yawn when you're tired? And why does one person yawing make others yawn?

A few theories:

Mainly to do with oxygen, carbon dioxide and the power of suggestion!

Believe it or not.. this Q made me yawn!

Hey Dilf....

it has to do with a lack of oxygen entering the brain (not very dangerous though)..so your mouth open somehow (probably from nerves triggering it) and you gain oxygen from the air....the reason yawning is contagious is unknown...but very interesting i think

[ju5t1n@hotma]

You yawn because you are tired and your body is slouching restricting the amount of air entering your lungs, tis just a way to get more oxygen ;-)

My students yawn all the way through their singing lesson.... ! Not because they are tired or bored, but because when you sing with your soft palatte raised, this sets it off. So it is a physical thing too.

When you see others yawn, your brain tells you there is a scarcity of oxygen, so you, in turn, yawn. It's a survival technique. Like adrenaline being released in times of stress / danger etc. We have no control of that either x x
