World Sleep Day, organized by the World Sleep Day Committee of the World Association of Sleep Medicine since 2008, is on March 21 every year.

World Sleep Day is to celebrate the benefits of good and healthy sleep. Sleep quality(质量) plays an important role in people’s health. Researchers say that there are a lot of advantages if we always get enough sleep. We can be smarter, thinner, healthier and more cheerful. Also we’re to have better skin, better memories and longer lives.

When you lose even one hour of sleep for any reason, it will influence your performance the next day.

In general, adults are thought to need at least eight hours of sleep a night, but a recent survey found that, on workdays, only 21% of them really get a full eight hours of sleep, and another 21% get less than six. For teenagers, a healthy amount is about eight to nine hours every night. However, about 80% of high school students don’t get enough sleep because of their schoolwork or some bad habits.

Twenty-seven percent of people in the world have sleeping problems. Now there are over 80 kinds of sleep disorders, and most people know little about their danger. So, for our good life and work, it’s necessary for us to realize the importance of sleep and try to have a good sleep.
