Human Physiological Question

Post by Hank Fist » Tue Jul 22, 2008 1:43 pm

The Itch.
What is the point of feeling an itch?

Discuss.



To me, the immediate reaction of scratching helps in some short term relief of a mild irritant, but in the case of, say poison oak (which I recently contracted from the back corner of my yard) you do nothing but damage the skin and open the way for infection.

Good question.


The other day I was at the gym doing 20-rep squats. For those of you who are pencil-dicks, knocking out 20 reps with reasonably heavy weight is hard to do and will make you feel like you're going to pass out by around rep 13 or so. I got a really bad itch on my nose on rep three. It really sucked. Next time that happens, I should yell "SCRATCH MY FUCKING NOSE!!!" to see if anyone actually does it.

Increased oxygen into the brain when one is tired. You're body is trying to help you keep awake.

That's psychological, let's keep things in the physiological realm.

People yawn to push oxygen out of their lungs that hasn't been expelled from regular breathing. You take a really deep breath, blow a small amount of it out, inhale again really deeply, do this for awhile and it'll build up a yawn.
