Junior high school students have poor sleep because of heavy review tasks, and some students even go to bed after midnight. Staying up late for a long time will cause metabolic disorder, and junior high school students are at a critical stage of physical and mental development, which is not only bad for their health, but also bad for their studies. Junior high school students should form a regular routine of going to bed early and getting up early. Regular work and rest can make students form a biological clock, sleep until they wake up, and quickly enter a state of sleep and study.
