First of all, we should eat a balanced diet, second, we should have high-quality sleep, and third, we should keep regular physical exercise. Maintain physical exercise 3-4 times a week 1 hour or more, and consciously increase the chances of getting up and walking at work (for example, change the water cup to a trumpet, get up and receive water many times). Consciously cultivate a regular biological clock, if external interference (sound source, light source, poor ability to resist the temptation of mobile phones, etc. ) can not be ruled out, you can try to supplement exogenous pineal hormone and follow the doctor's advice without causing extra burden to your body.
