Ensure adequate sleep time every day, primary school students, junior high school students and senior high school students.

Primary school students, junior high school students and senior high school students should ensure adequate sleep time every day as follows:

1, the first is the necessary sleep time. Pupils sleep 10 hours a day, junior high school students sleep for 9 hours and senior high school students sleep for 8 hours.

2. The second is the school schedule. Primary school starts at 8: 20 in the morning and middle school starts at 8: 00. At the same time, it is emphasized that the school should not require students to arrive at school in advance, and it is necessary to ensure the necessary lunch break if conditions permit.

3. The third is the time to sleep at night. Pupils are generally no later than 2 1: 20, junior high school students are generally no later than 22: 00, and senior high school students are generally no later than 23: 00.

At the same time, guide parents and students, make schedules for students' work and rest, implement self-management, work and rest rules, and go to bed on time. Only by controlling the school schedule and students' bedtime at night can students effectively ensure the necessary sleep time.

In view of the external factors affecting students' sleep, the Notice puts forward three "interruption mechanisms", requiring homework, off-campus training and games to make way for students' sleep.

The first is the "interruption" of homework, which requires primary school students to basically complete their written homework at school, while middle school students complete most of their written homework at school. If individual students fail to finish their homework before bedtime after efforts, parents should urge them to go to bed on time, don't stay up late and ensure adequate sleep.

The influence of sleep on children;

First of all, we should strengthen sleep propaganda and coordinate management at all levels. The majority of primary and secondary schools, teachers, parents and students should fully raise their awareness of the importance of sleep health, enhance their understanding of sleep time requirements and healthy sleep habits of different age groups, set class hours and schedules that meet the physiological characteristics of primary and secondary school students, and ask them not to arrive at school too early in the morning and arrange lunch breaks reasonably at noon.

Secondly, respect individual differences and strengthen independent management. The daily sleep demand of primary school students is 9- 12 hours, and that of middle school students is 8- 10 hours. Teachers and parents can strengthen communication with children, work out a schedule suitable for individual students together, and at the same time, they can know whether they sleep well from the aspects of children's mental state and self-feeling, and adjust the schedule according to the actual situation.
