People spend almost a third of their lives doing one thing: sleeping. Every year, there is a special day for people around the world to celebrate the importance of good and healthy sleep—World Sleep Day.
Sleep is like food for the brain. Enough sleep helps the body and brain grow. 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 said that about 80 percent of middle school students don’t get enough sleep. It has influences (影响) on students’ school life. Students without enough sleep may get poor grades. They cannot 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. Taking a 20-minute nap (午睡) during the day is also useful. Good sleep habits help a lot. For example, try to go to sleep and wake up at the same time every day, even on weekends and during holidays.
