How come's it....?

that we yawn when we're tired? Why is that?

And why do we laugh when tickled, and not when we try to tickle ourselves?

Because you're tired, your lungs don't inhale to full capacity, so you yawn to get a healthy intake of air (I think).

Don't know why we laugh, but I think you can tickle yourself, but tend to not do it as hard as when someone else does it, so it doesn't tickle as much. Just think about when someone else does it, they usually do it pretty hard.

Yeah, your diaphragm kinda slows down so your body yells it needs more oxygen so you yawn.

I guess thats why you feel a little more awake afterwards too.

i have a theory that yawns catch because there's a change in air pressure. but it's probably ridiculous.

I read an article once that said yawning can come around due to increases in carbon dioxide in the air. So yeh you could be right.

Yeah but surely not at the exact same second as someone else yawns? I think it's psychological, if someone else yawns, it reminds your brain to make you yawn to keep the air flowing. ken.

Yeh. Scientists have proved that yawns are contagious. Somthing about mind signals and what not

All_in_black · 7th November 2004, 11:26 PM

Well, the key to getting rid of them asap is to force them out.
