Up to two thirds of children don’t

Up to two thirds of children don’t get as much sleep as they should do, and this can make them nervous and slower at school, researchers say.
So how long should young people sleep each night? The answer is between eight and ten hours. If you don’t get enough sleep at night, you’ll have less energy the next day.
But the researchers say many children have missed out on 4500 hours of sleep by the time they are seven years old. They say children miss sleep because they have TVs and computers in their rooms, and busy parents don’t read to their younger children at night any more. The traditional “bedtime story” helps children to relax and fall asleep. Children with TVs and computers in their bedrooms were more likely to sleep badly, and to get less than eight hours sleep. Even losing one hour’s sleep a night can mean that children do less well at school.
German scientists think that your brain keeps working while you’re asleep. To show that they were right, they gave two groups of people a problem to work out. One group went to sleep, and the other group stayed awake. The result? The people who slept worked out the answer more quickly, suggesting their brains had been trying to find the answer while the people were asleep. So, make sure you get enough sleep tonight, you’ll be at your best tomorrow.

高达三分之二的儿童没有得到他们应该得到多少睡眠，研究人员说，这可以使他们紧张和较慢的学校，所以要多久
。年轻人每晚的睡眠时间？答案是八小时和十小时之间。如果你没有得到足够的睡眠，你就会有较少的第二天能源
。但是研究人员说，许多孩子已经错过了4500个小时的睡眠的时候，他们是七岁。他们说孩子想睡觉因为他们有在他们的房间里的电视和电脑，和忙碌的父母不读他们的年轻的孩子晚上再。传统的“睡前故事”帮助孩子放松和入睡。卧室有电视和电脑的孩子更有可能睡得不好，要少于八个小时的睡眠。即使失去一小时的睡眠可能意味着孩子们在学校中成绩不好。
德国科学家们认为你的大脑一直工作在你睡着的时候。来证明他们是正确的，他们给两组人来解决问题。一组人睡觉去了，而另一组保持清醒。结果呢？睡的人解决得越快，表明他们的大脑一直在试图找到答案，当他们睡觉的时候。所以，确保你获得充足的睡眠时间，明天你会在你最好的。
