     "Just five more minutes." "I'm tired!" "I can't get up." If you have ever had trouble getting up in the

morning, you are not alone. Many kids in the United States do not get enough sleep.

     Your body needs sleep-and lots of it! "Evidence (证据) shows that elementary-age children need at

least nine hours of sleep per night," said sleep expert Dr. Carl Hunt.

     Kids who do not sleep enough cannot do their best, experts say. A tired kid may be moody and act

badly. Being tired can also cause kids to forget things, have trouble learning, and have trouble playing

sports.

     Not sleeping enough can also affect kids' safety. Experts say children who are tired are more likely

to suffer injuries.

     Lots of kids lose sleep because they are busy. Many take part in after-school activities. Then they

go home, eat dinner, and do homework. Afterward, many kids watch TV, play video games, and surf

the Internet. That leaves less time for sleep.

     Sometimes you may not be able to go to bed early. But, if you get a choice whether to stay up late,

think twice. A good night's sleep can help you feel your best!
