At present, the serious lack of sleep among middle school students has become a common social phenomenon. The survey found that most students get up from 6 am to 6: 30 am or after 6: 30 am. If getting up before 6: 30 means getting up early, most students get up early. Some students say that they would rather not eat breakfast in order to sleep for five more minutes in the morning. It can be seen that students still want to have enough sleep, after all, this is a physiological need. In addition, some students said that their parents forced them to get up early and told them to get up early and read books in the morning. Most students sleep from 10: 30 to 1 1: 30. If they sleep after 10: 30 in the evening, most of them can't reach the standard sleep time (the Ministry of Education stipulates that junior high school students should sleep for 9 hours every day) and are prone to fatigue. The survey found that most students don't take a nap at noon, and the reason for not taking a rest is that they don't have the habit of taking a nap or have too much homework at noon. Statistics show that on average, 40% of students stay up late because of too much homework every day, and by the third grade, it is as high as 50% or more. Only about 20% students have the habit of taking a nap, which shows that most students don't realize the importance of taking a nap. In addition, with the increase of grade (from grade one to grade three), the number of students who can guarantee 9 hours' sleep gradually decreases. Lack of sleep among middle school students also has a bad influence on students themselves. It will not only reduce the body's resistance, make it prone to various diseases, but also lead to inattention and decreased attention during learning, thus affecting the learning effect. Long-term lack of sleep will cause psychological problems and pose a potential threat to the physical and mental health of teenagers. Because our middle school students' self-control ability is not yet adult, we hope that parents will let their children go to bed early, and also ask them to go to bed early to urge and help them save time. At the same time, teachers should make students realize the importance of sleep and give them the greatest help.
