Sleep

Babies sleep about eighteen hours a day．Mrs. Thatcher and Napoleon both said they only needed to do it three or four hours a night．Sleep．No one can live without it．But how much do we really need?

Research（研究）by the National Sleep Foundation in Washington says that we all need eight hours' sleep every night．Scientists have found that people who sleep for less than six and a half hours a night are more often ill than people who sleep for eight hours．Going without sleep also increases（增加）the chance of serious illness．Workaholics（工作狂）who sleep for less than five hours often die young，and do less well at work．

The scientists found that adults（成年人）usually sleep for seven hours a night，with 32% sleeping less than six hours．

It also says that the idea that we need less sleep as we get older is completely untrue．“People have no idea how important sleep is to their lives，” Dr Thomas Roth，director of the Foundation says．“Good health needs good sleep．”

“But not too much of it，”says Professor Jim Horne of Loughborough University．“Sleep is like food and drink，”he believes，“you would always like to have a little bit more，but that doesn’t mean you need it．” Professor Home studied a group of people who could spend as many hours as they wanted in bed，after ten hours they didn't find it any easier to get up in the morning．And people who sleep for more than nine hours a night die younger than people who usually sleep for seven or eight!

THE 'China Daily', a newspaper, reports that the average student goes to sleep at 00:30 am. Even if that's an exaggeration (夸张), it's too close to the truth. Scientists say teens should sleep nine hours each night. But that's hard to do.
    Some even "pull all-nighters". These are lazy students who have homework due (到期) the next day that they haven't done. In the morning they don't look healthy and you can tell who's been doing it.
    One reporter did a survey on the problem. She found that most kids pull all-nighters to finish homework, but some do it for other reasons, such as playing computer games!
    Maybe the students’ lack (缺乏) of sleep is because of laziness - But in fact, few of them are lazy- or maybe it's because they have too much to do in middle schools.

Zhang Jialiang, a student in a middle school, usually go to bed around midnight. He says, “If I stayed up past 00:30 am, I wouldn't get any work done. I'd be falling asleep at my desk. My classes begin at 6:50 am. I'm partly awake in my first class. By the second, I'm slightly drowsy(困倦的). By my third class, I'm sleepy. By midday I'm finally wide-awake. But by 3:00 pm, I'm slowing down again. Yet I get more sleep than the China Daily's 'average student'.”
    Most Chinese middle schools seem to have a similar problem with sleepy students.
    Middle school classes start at 6:50 am, so students have to wake up one and a half hours before that to get ready and catch the bus. It's believed that lack of sleep can damage (损害) both grades and health.
    Some schools are paying attention. Classes in those schools start at 7:30 am.

“At three or four in the morning and I surf the net.”

“I often check my e-mail forty times a day.”

“I often spend more than three hours during one time on the net.”

“I spend more time in chat rooms than with my ‘real-1ife’ friends.”

Do you know any people like these? They are part of a new addiction（瘾）called Internet addiction. Internet addicts spend at least thirty to forty hours online every week. The use of the Internet can be an addiction like drug(毒品) use. People lose control of the time they spend on the Internet. For example, one college student was missing for several days. His friends were worried, and they called the police. The police found the student in the computer lab: he was surfing the net for several days straight.

Studies show that about 6 to 10% of Internet users become addicted. And people worry about the teens because the Internet is changing the playing field for some of them. They spend more time in cyberspace than in the real world of friends and family.

Is “surfing the net” a hobby or an addiction for you? You may have a problem if you have these symptoms（症状）：

●You do not go to important family activities or you do not do school work because you like to spend hours on the Internet.

●You can’t wait for your next online time.

●You plan to spend a short time online, but then you spend several hours.

●You go out with your friends less and less.
