1 . As we all know, it isn’t healthy to stay up late and poor sleep quality can leave us feeling low. However, many people still cannot get enough sleep, especially the young.
Over 60% Chinese youths aged 6 to 17 sleep less than eight hours a day, according to a report released by the Chinese Sleep Research Society (CSRS). Among 13-to 17-year-olds, the figure is more than 81%.
According to the study, too much school homework is a major cause for sleep loss among young people. For example, from Monday to Thursday, 8.4% of them would still be busy with their homework after 11 pm. Another major cause of young people’s inadequate sleep is the frequent use of electronic devices (电子设备). More than 41% children and teenagers who sleep too little use electronic devices such as computer tablets and mobile phones, the survey found.
Lack of sleep among children and teenagers has raised concern. “Sleep loss can lead to weakened immunity (免疫力) and memory, and can also prevent physical growth,” Wang Zan, a member of the CSRS, told People’s Daily.
To reduce students’ academic burden, the Ministry of Education and eight other departments released a guideline (指南) on Dec 28. For example, it says that junior high students should spend no more than 90 minutes on homework and senior high students must do their homework in a proper time limit. Local education authorities across China should also take more steps to help students get more sleep, including delaying the start of morning classes by half an hour.
