World Sleep Day is March 21. Many experts have held a press conference(新闻发布会) in Beijing Hotel. Sleep is sometimes called “the cousin of death”. But it is also one of the most important things we need to stay alive. People spend almost a third of their lives doing one things: sleeping. Sleep is like food for the brain. Enough sleep helps the body and brain grow and develop.

People of different ages need different amounts(数量) of sleep. According to the National Sleep Foundation in the US, adults need seven to nine hours of sleep every night. For students aged 10 to 17, a healthy amount is about eight to nine hours per night.

However, many students don’t get enough sleep because of early school start times and too much homework. The China Youth and Children Research Center reported that about 80% of middle school students don’t get enouh sleep. Students without enough sleep may get poor grades. They can’t pay attention in class or do well in sports.

To solve this problem, scientists advise that students should get less schoolwork and more time to sleep. There are some other ways to help people get enough sleep, such as taking a 20-minutes nap(小睡) during the day. Good sleep habits are also helpful. For example, try to go to sleep and wake up at the same time every day, even on weekends and during holidays.
