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       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      energy the next day.

So, make sure you get enough sleep tonight,        you’ll be at your best tomorrow．
