sleepy..zzzz

Post by whizzbee » Wed Apr 23, 2008 4:21 pm

ok, my question is how can, or, why can we feel sleepy? i know the main answer is : we don't sleep long enough (+- 6 hours a day), but what i am asking about is what's the process of it? is it true if it is related to the lack of oxygen in our brains?

recently, i had enough sleep (i sleep more than 6 hours a day), but i can still feel quite sleepy sometimes,this happened even when i did or read the things i like and this also happens to my friends, so i wonder if there are some tips to get rid of this thing, ergghh..

thank you!! :D
