The following is the More than 80% of Chinese primary and secondary school students fall asleep recommended by recordtrend.com. And this article belongs to the classification: Life data.

According to the report on the development of China’s national mental health (2019-2020), the lack of sleep among Chinese adolescents continues to worsen, with 95.5% of primary school students, 90.8% of junior high school students and 84.1% of senior high school students falling short of the standard. There are two main aspects of teenagers’ lack of sleep: first, the proportion of less than 8 hours of sleep on school day increased by 1 percentage point.

In 2009, 47.4% of teenagers sleep 8 hours or more on school day, while only 46.4% in 2020; the average sleep time of teenagers in 2020 is 7.8 hours, 0.3 hours lower than that in 2009.

Segment analysis shows that 95.5% of primary school students sleep less than 10 hours a day, with an average of 8.7 hours; 90.8% of junior high school students sleep less than 9 hours a day, with an average of 7.6 hours; 84.1% of senior high school students sleep less than 8 hours a day, with an average of 7.2 hours.

Second, the sleep duration on school days showed a downward trend with the increase of grade, and the phenomenon of weekend supplementary sleep showed the differentiation of school periods. Compared with more than ten years ago, in 2020, the sleep duration of adolescents in each period of school presents a downward trend. The average sleep duration of primary school and junior high school is reduced by about 40 minutes on school day, and that of senior one and senior two is reduced by 10 to 20 minutes. The average sleep duration of primary school students on weekends is reduced by about 12 to 25.2 minutes, that of junior one and junior two is reduced by about 20 minutes, and that of junior three and senior high school is more serious, with a decrease of 40.2 minutes To 51.3 minutes.

In the latest mental health blue book released on the same day, the sub report of “mental health status and needs of college students in 2020” shows that in the survey, college students also generally have the problem of insufficient sleep. Nearly 70% of undergraduates and nearly 50% of college students sometimes report insufficient sleep.

The report surveyed 8447 college students (3631 undergraduates and 4816 junior college students) in the first half of 2020, and found that 90% of them thought their mental health was good. The evaluation shows that more than 70% of undergraduates have no depression, and about 90% of college students have no depression. Part of the reason for this difference is that college students use interpersonal support to regulate emotions better than undergraduates.

In addition, the report also reminds that the survey found that college students’ mental health is generally good, but a certain proportion of depression, anxiety and other problems can not be ignored.
