I think one of the most painful sensations is the feeling that you get when you force yourself to stay awake.

I would know; I experience this sensation during school almost every day. While falling asleep in class is nothing uncommon at Uni, it’s a phenomenon with significant consequences.

The number of sleep-deprivation articles that have been recently written made me ask the question: Why do we yawn? Is it because we are feeling tired or really bored? And why is it that whenever you see someone open his or her mouth wide to yawn that you also feel the urge to yawn?

It is a typical school night.

"I'm tired. I didn't get ANY sleep last night." This is a common remark that you can hear in the hallways, the classrooms, on the phone, and any space that students occupy. Complaining seems to be the Olympic sport of high school, and people are constantly battling for the gold. Unfortunately, this contest isn't held once every four years, but every day and everywhere.

Ever feel sleepy or drowsy at school?
