1. Maintain good eating habits and work and rest habits. Eat on time and don't let your stomach get hungry or full. Eat until seven or eight points are full. You must have a good breakfast and avoid overeating. Try to eat less sugar and spicy food, don't overdo alcohol and tobacco, mix meat and vegetables, and have a balanced nutrition. Work and rest should be regular, you can go to bed early and get up early, or you can go to bed late and get up late, but stay up as little as possible, and go to bed before 10 at night to ensure seven or eight hours of sleep every day.

2. Keep exercising. If you have time, you can exercise properly in the morning and evening and do aerobic breathing. Playing ball, running, walking, practicing yoga and dancing are all options. Go out for a walk, climb mountains and breathe fresh air during the holidays.

3. Regular physical examination. Go to the hospital for a comprehensive physical examination regularly for half a year or a year to understand all aspects of your body and seek medical treatment in time to improve.
