Due to the high academic pressure, high school students should get about 7-8 hours of sleep a day to ensure adequate mental state and study efficiency during the day. High school students are in the stage of development, and it is vital to ensure sufficient sleep for growth and development. When sleep at night is not enough, you can rest for half an hour at noon every day, which not only can ensure the needs of normal development, but also can promote the normal function of the brain and avoid the degradation of brain cell function and cause memory loss. When the study task is heavy, high school students can timely supplement nutrition, such as walnuts, pine nuts, fish and shrimp and other foods, but also can take brain tonic drugs, such as tranquilizer, vitamin B, etc.. Also some physical exercise can be a good way to improve sleep. Parents and teachers should pay attention to the situation of high school students, communicate with them in time, and not give them too much pressure to avoid anxiety that affects their sleep.
