　　March21st is World Sleep Day this year.Its aim is to celebrate the benefits of good and healthy sleep.
　　Fangfang,from Liaoning,just became a high school student last September.She gets up at5:30a.m.every day and goes to bed at about midnight.Fangfang feels sleepy all the time.“I want to finish all my homework first,”she said.
　　Sleep is like food for the brain.Enough sleep helps the body and brain grow and develop.According to the National Sleep Foundation in the US,adults need seven to nine hours of sleep every night.For students who are10to17years old,a healthy amount is about eight to nine hours every night.
　　But many students don't get enough sleep because of early school start time and heavy homework.About80percent of middle school students don't get enough sleep,the China Youth and Children Research Center reported.For some students,they want to sleep early,but they keep worrying about their schoolwork and can't fall asleep quickly.For others,they may even have insomnia,and usually they have to ask the doctors for help.
　　These sleeping problems greatly affect people's life.Some doctors found out that lack of sleep for teenagers lead to poor grades.Students without enough sleep can't pay attention in class or do well in sports.Also,they often become anxious easily.
　　Luckily,with good sleep habits,it is easier to fall asleep.Some of these good habits include avoiding drinks that make people excited late in the day,going to sleep at the same time every night,and sleeping in a comfortable place that is dark,quiet,and neither too warm nor too cold.
　　More tips to get a good night's sleep:
　　.Exercising during the day.You'd better do sports three hours before going to bed.
　　.Don't eat big meals before bedtime.Drink a warm glass of milk.
　　.If you stay awake worrying about things,try making a list of things that you need to do before you go to bed.
