In America, most people don’t get enough sleep. Children aged 5 to 12 are advised to sleep 10 to 11 hours every night, but most of them can’t sleep that long. A study found that about 41 million American workers got less than six hours of sleep every night. Scientists worry that parents are passing their bad sleeping habits down to their children.

In the study, Reut Gruber and some other scientists either added or reduced on hour of sleep for healthy children aged 7 to 11. They watched the children for five nights. They wanted to know if the amount of sleep can affect a child’s behavior.

Before the study began, students were asked to sleep the same amount of hours as usual. Their teachers were asked to record their behavior. After five nights of the records, scientists found that those who slept one hour less behaved worse than those who slept one hour more. Students with less sleep were more likely to feel sad and had more problems paying attention.

The scientists chose to study children in their homes instead of in a laboratory, because they wanted to find out how everyday changes might affect children’s behavior at school. “In the study, nobody became a talent, and nobody became crazy. But small changes in children can really make a big difference,” says Gruber.

Researchers say that nearly two thirds of children don't get enough sleep, and this can make them nervous and slower at school. So how long should young people sleep each night? The answer is between 8 and 10 hours. If you don't get enough sleep at night, you'll have less energy the next day.

A report shows that children sleep less 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 peacefully. 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 worse than usual at school.

British scientists think that your brain keeps working while you're asleep. To show that they were right, they have done an experiment. They gave two groups of people a problem to work out. One group went to sleep, and the other group stayed awake. You want to know the result? The people who slept worked out the answer more quickly. Researchers explained that their brains were trying to find the answer while the people were asleep. So, make sure you get enough sleep tonight, 'and you'll be at your best tomorrow !
