Sleep making you tired?

[GuidoHunter]

Sleep is for champions. Heroes and champions. Aside from the multitude of health benefits of sleeping, just getting rest is awesome.

I'm not fully functional unless I get at least seven hours of sleep, and I'm well-rested after nine.

Jam's chart is so right, though. 11-13 hours of sleep sucks when you get up, even though the process of sleeping rules, but 15+ is just stellar.

Its actually quite simple why people often wake up tired. People become tired when the chemical Melonin is produced in the brain, and they therefore will go to sleep. Melonin levels stay high until youre rested, so you dont wake up for no reason. Therefore, if you wake up with too little sleep, the melonin is still in your brain, and if you sleep too much and pass the time when youve had the amount of sleep you generally need, your brain continues to produce it since it doesn't really know what to do in this situation and its best not to wakeup if you still are trying to sleep.

edit: I'm not sure if its melonin, but some chemical that acts in the above way.

Sleep is very vital. While watching the discovery channel a few years ago, some people were doing some expeiments with mice. They were studying(sp) the effects of sleep on the mice. Too much, too little, and so foruth. Well, they decided to keep one up as long as possible. And after 18 days, the mouse just died. So there. If you dont sleep for 18 days, you will die.
