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!

I usually get up at 5:00. I make coffee, go to my desk and work. When my boys get up, I’m theirs. I follow the min to the kitchen and make them breakfast. While they’re eating, I make their lunch, pick out their school clothes and get the little one dressed.
My wife takes them to school. I bring them home. I am not the only father at the school gate. The boys and I walk the 12 blocks home unless the weather is terrible. Then we take the subway. I remind them of looking out, like an animal looking after their babies.
At home, they play on the computer and the little one will draw, sometimes for hours. When their mother comes home, they run to her. She has been in the official day and tired, but her attention is all on them.

Do you know why you sleep? You may think it’s because you’re tired. Or perhaps you’ve been told sleep is good for you. Yet no one knows exactly why or how people sleep.

Until the early 1950s, most scientists thought the body and brain rested during sleep. Then a scientist watched people sleep. He noticed that during periods of between 5 and 30 minutes each, sleepers’ eyes made rapid movements, as if they were watching something. He called these periods REM sleep, for Rapid Eye Movement. Periods when sleepers’ eyes did not move he called non-REM sleep.

Whenever the scientist woke people during REM sleep, they were having vivid dreams. Measurements showed that sleepers’ pulses(脉搏)went up quickly during REM sleep. Their breathing, heartbeat, and the blood going to the brain also increased. Far from being a time of rest, REM sleep is a time when the body is hard at work. Scientists still don’t know the reason for this. Some believe REM sleep makes learning easier. Babies spend a lot of time in REM sleep. Because of this, some scientists believe that REM sleep helps the brain grow. Others think REM sleep is a time for the brain to empty the day’s garbage.

One thing all the scientists agree on is that sleep is necessary. Without enough sleep, people make mistakes. Most major car accidents happen during the early morning hours, when people are sleepiest.
