On the basis of what you can, keep a good routine, exercise every day (30 minutes-1 hour), eat nutritious and healthy food, refuse junk food, and have some leisure time, such as reading books and magazines. Of course, there is time limit, and you are not fascinated or interested, so that you can feel happy. When there is an exam, adapt to the pressure and continue to maintain the previous life rules. I am a medical student, comparable to a high school student. I used to see a doctor because I was too tired for exams. The doctor said there was nothing wrong with me. The second thing was to follow the above instructions and relax! Young people have strong adaptability and self-healing ability. And living well is a kind of health!
