Do you ever stay up late to play video games or watch TV?If so,you may want to think twice the next time.Experts say even one more hour of sleep a night counts new study shows that more sleep can help kids do better in school.
For two nights,a group of kids who took part in the study went to bed at their usual bedtime.After that,they were given tests for memory and attention span(注意广度)．Both of these things are important for learning in school.
On the third night,some kids went to bed one hour earlier than usual.Others went to bed one hour later.The next day,experts tested the kids again.Here is what the experts found：The kids who slept one more hour improved their test scores.The kids who lost an hour of sleep did not improve their scores.
Most third graders need at least nine hours of sleep each night,experts say.However,studies show that many kids are not sleeping enough.That can make it hard for them to pay attention in school.
Going to bed early is not easy,experts agree,but it’s worth it!
One_more_hour_of_sleep_may_mean_the_difference_between_doing_well_and_falling_asleep_in_class.
