Abstract: One-third of a person's life is spent sleeping. People who do not sleep for 4 days will die. It can be seen that sleep is a normal physiological phenomenon of human beings. Relatively speaking, middle school students have to work hard until midnight every day to rest due to heavy academic work. Many middle school students do not get enough sleep, which not only affects the next day's study and reduces the efficiency of listening to lectures, but also affects appetite, thereby affecting the healthy development of the body. To this end, through investigation and research, the author discusses the current sleep problems of middle school students, as well as some countermeasures and suggestions to solve this problem.

Introduction Adequate sleep, balanced diet and appropriate exercise are three health standards recognized by the international community. But there is a general lack of awareness of the importance of sleep. Animal experiments show that if mice do not sleep for more than 6 days, they will develop symptoms of movement disorder until the brain wave voltage decreases and disappears, and they die. In comparison, a person can survive for 7 days with only water and no food, and only 4 days without sleep. Insomnia disorder has become a prominent problem threatening the public around the world. Medical research shows that occasional insomnia can cause fatigue and lack of coordination the next day, while long-term insomnia can lead to consequences such as inability to concentrate, memory impairment, and inability to work as expected. 2. Sleep problems among middle school students (1) Questionnaire survey Some people say that students are the most “sleepy” group. In order to understand the sleep status of middle school students, the author recently conducted a survey on the sleep of middle school students in our school and three nearby township middle schools. 300 questionnaires were distributed, and the 282 valid answers returned showed that 78.7% of students had sleep problems. Sleep disturbance or insufficient sleep time. The survey results showed that including lunch break, 146 of the 282 middle school students had sleep disorders, 86 of whom slept less than 8 hours, and all 136 high school students slept less than 8 hours, that is, 222 students did not sleep enough. Accounting for 78.7% of the surveyed people. (2) Analysis and Thoughts on Survey Results The author conducted statistics and analysis on the survey results, and found that 80% of students have sleep disorders, and nearly 60% of students have daytime dysfunction (feeling tired and energetic during the day) due to sleep quality problems. Insufficient), which will directly affect student performance and lead to psychological problems. Through surveys, it has been found that serious lack of sleep among middle school students has become a common phenomenon. Most students get up around 6 o'clock and go to bed around 11 to 12 o'clock. They do not get enough sleep due to too much homework. Very few students can guarantee the standard 8 hours of sleep. few. The self-control ability of middle school students has not yet reached an adult state, and there are mainly problems in the following aspects: 1. The higher the grade, the more sleep deprivation. Statistics show that the rates of sleep deprivation among junior high school students and high school students are 30.5% and 78.7% respectively. The rate of insufficiency was significantly higher than that of junior high school students. The average sleep time of 93 junior high school students was 8.2 hours, while the average sleep time of 81 high school students was only 7.4 hours. 2. Graduating students sleep significantly less. Among the four schools surveyed, the average sleep time of students in the first grade of junior high school was 7.9 hours, while the average sleep time of students in the first grade of junior high school was 8.6 hours. The contrast in high school is even more obvious. The average sleep time of a class in the first year of high school is 7.7 hours, while the average sleep time of a class in the third year of high school is only 6.9 hours. Excluding lunch breaks, the average sleep time of 53 high school seniors at night was only 6 hours. 3. A survey of the main factors affecting sleep shows that the main factors affecting students’ sleep quality are excessive academic load, environmental influence and personal emotions. Students who sleep less are mainly due to going to bed late. Statistics show that 95% of senior high school students, 80% of senior high school students and 81% of junior high school students often go to bed later than 23:00, and 61% of junior high school students go to bed later than 23:00 at least 4 days a week.
