Sleeping in on Saturday after a few weeks of too little shuteye may feel refreshing, but it can give a false sense of security.
New research shows long-term sleep loss cannot be cured that easily. Scientists researched the effects of short- and long-term sleep loss and found that those who suffer long-term sleep loss may function normally soon after waking up, but experience steadily slower reaction times as the day goes by, even if they had tried to catch up the previous night.
The research has important safety significances in an increasingly busy society, not just for shift-workers but for the roughly one in six Americans who regularly get six hours or less of sleep a night.
“We know that staying awake 24 hours without sleep will affect your performance to do all sorts of things, and this effect equals to drinking too much when driving,” said lead researcher Dr. Daniel Cohen of Boston’s Brigham and Women’s Hospital. But when those who suffer long-term sleep loss become all-nighters, “the harm is increased ten times,” Cohen said.
The National Institutes of Health says adults need seven hours to nine hours of sleep for good health. Regularly getting too little sleep increases the risk of health problems, including memory impairment and a weakened immune system. More immediately, too little sleep affects reaction times; sleepiness is to blame for car crashes and other accidents.
It has critically important complicated and unexpected results for anyone who works “crazy hours” and thinks they are performing fine with a few hours of weeknight sleep, said Harris, director at New York’s Montefiore Medical Center. “Don’t think you can just bank up your sleep on the weekend, because it doesn’t work that way,” he warned.

Everyone has got two personalities—the one that is shown to the world and the other that is secret and real. You don't show your secret personality when you're awake because you can control your behaviour，but when you're asleep，your sleeping position shows the real you. In a normal night，of course，people frequently change their position. The important position is the one that you go to sleep in.

If you go to sleep on your back，you're a very open person. You normally trust people and you are easily influenced by fashion or new ideas. You don't like to upset people，so you never express your real feelings. You're quite shy and you aren't very confident.

If you sleep on your stomach，you are a rather secretive person. You worry a lot and you're always easily upset. You're very stubborn，but you aren't very ambitious. You usually live for today not for tomorrow. This means that you enjoy having a good time.

If you sleep curled up(卷曲), you are probably a very nervous person. You have a low opinion of yourself and so you're often defensive. You're shy and you don't normally like meeting people. You prefer to be on your own. You're easily hurt. 

If you sleep on your side，you have usually got a well－balanced personality. You know your strengths and weaknesses. You're usually careful. You have a confident personality. You sometimes feel anxious，but you don't often get depressed. You always say what you think even if it annoys people.
