2 . Children and teens in China do not get enough sleep, which can put their health at risk. Nearly 63 percent of Chinese youths at 6 to 17 sleep less than eight hours a day. Among 13- to 17-year-olds the figure is more than 81 percent, according to a survey covering nearly 70,000 children and teens across the Chinese mainland, Hong Kong, Macao and Taiwan.

The report found that the heavy school homework and the use of electronic devices (设备) were the two top causes for the lack of sleep. From Monday to Thursday, 8.4 percent of the group would still be busy with their homework after 11 pm. More than 41 percent of children and teenagers who sleep too little use electronic devices such as computers and mobile phones. Other than that, youths whose parents use smartphones in front of them are more likely to have less sleep. Other factors, such as noise and increasing light pollution, contributed to the problem, the report said.

The survey also suggests that good sleep results in higher efficiency (效率) in study. Students who sleep longer generally finish homework in two and three hours per day, while those who sleep less require four to six hours.

Gao Xuemei, vice-president of Chinese Sleep Research Society, said studies have shown that decreasing sleeping time for children and teenagers has been a global trend in the past 10 years, but the problem appears to be worse in East Asia, including China, largely due to a heavier load of school homework. Besides, the overuse of electronics devices in China is responsible for teenagers’ sleeping problems as well.

“Lack of sleep among children and teenagers needs more attention, because it can seriously affect their health and growth,” Gao said. She also suggested that local education officials take measures to help students get more sleep, including putting off the start of morning classes by half an hour.
