Sleep is important!
We need sleep to make us healthy and happy!
Every living thing sleeps, from insects to whales. Some animals sleep 20 hours a day! Most people don’t need to sleep so many hours, but our sleep is also important.
天黑了，星星开始眨眼睛。躺在床上回想着今天的趣事，你感觉眼皮越来越沉，一转眼你便来到了另一个世界，开始了一段奇幻的旅程。恭喜你！你今天的睡眠任务完成了！
同学们知道吗？睡眠对我们来说非常重要，就像汽油对汽车一样：没有油，汽车就跑不动；不睡觉，我们就不能好好地学习、玩耍。而定于每年3月21日的世界睡眠日就是为了提醒人们睡觉有多重要，所以快来学学睡觉的知识吧！

Why We Sleep
Sleep helps our body and brain develop and grow.
How Sleep Works
Your body rests, but is also active during sleep.
In the daytime, you run in the playground, learn at school, eat meals, and at night your body and brain go to rest, right? Wrong! When you are sleeping, your body and brain are very busy getting ready for a new day.
Sleep and You
Kids between the ages of 5 and 12 need 10 to 11 hours of sleep each night.
When you have a good sleep you can:
● Pay attention better in class
● Be creative and think of new ideas
● Fight sickness so you can be healthy
● Be in a good mood
● Get along with friends and family
