World Sleep Day is on March 21st every year, showing the importance of daily sleep.
Enough sleep plays an important role in people's health. We can be smart, healthy and active when we always get enough sleep. We can also have good skin and live longer. When you lose even one hour of sleep, it will make you feel bad the next day and do harm to your health.
In fact, adults need at least eight hours of sleep a night. But a survey finds that only 21% of them really get a full eight hours of sleep on workdays, and another 21% get less than six hours. For middle school students, they need about eight to nine hours per night to keep healthy. However, about 80% of them don't get enough sleep because they need to do too much homework or they have some bad habits.
So, for a better life and better work, it's time for us to know the importance of sleep and try to get good and enough sleep. There are some ways to help us sleep well, like staying away from coffee at night, having some milk before sleeping, listening to some light music, reading some books, and so on.
