Sleep is like food for the brain. Enough sleep helps the body and brain grow and develop. However, many Chinese do not sleep well, and many do not pay enough attention to sleep.
The Chinese Medical Doctor Association released the 2013 China Sleep Quality Index (指数) on March 19 to mark World Sleep Day – March 21.
According to the index, nearly a quarter of Chinese people don’t sleep well. Half said that they feel tired after getting up and 15 percent people have trouble falling asleep.
Ye Jingying, a sleep expert at Beijing Tongren Hospital, says: “If people often wake up during the night, or always feel weak and tired in the day, they should pay attention to their sleep pattern (模式).”
Many people play with their cell phones or iPads before sleeping. The report said that this is one of the main reasons for bad sleep. Other reasons include stress and bad moods.
How to sleep well? Above all, get enough sleep. Seven to nine hours of sleep every night is perfect for an adult, and eight to nine hours is best for a teenager.
Forming good sleep habits is important. The report suggested that people need to keep away from digital devices (数码产品) for at least an hour before sleep. The lights keep their brains excited for a long while. Other suggestions include: try to go to sleep and wake up at the same time every day, even on weekends and during holidays, and do the same relaxing things before bed each night, like listening to soft music.

Childhood is a time of fun and games. Many people still remember when they were young, they often played games like hide-and-seek and chess. Playing teaches children how to get with others, and it also helps to exercise the mind and body. However, children today spend most of their time in front of the computer, playing video games.

A recent survey found that in the US. Children between 8 and 12 spend at least 13 hours a week playing video games or "gaming". Boys of this age spend even more time, almost 16 hours a week. Although some people will say that gaming is helpful, it brings many problems as well.

One big problem is that kids who spend most of their time on games might have difficulty communicating with real people. They might have trouble sharing and resolving (解决) problems because they do not practice these skills when sitting alone at a computer.

Another problem is about health. Game players usually sit for hours without doing any exercise. And they might not eat healthily. As a result, they might be out of shape.

Next, game players might have trouble with their lessons. Many of them spend more time playing games than working on their homework. In the end, they fail in the exams.   

Finally, it is always possible that the gamers become addicted. Some people play four or five hours a day or even all day. This happened to a 28 - year - old Korean man. He spent about 50 hours playing an online game without sleeping or eating well. He died while gaming!

This is one example of the dangers of video gaming. It tells us that video gaming, like everything else, should not be done too much. A few hours a week should not hurt, but several hours a day just might be dangerous to your health.
