Every time I get up in the morning, I say I should go to bed early tonight, but I can't go to bed until one or two every night. How to change it?

This kind of situation exists in many people and is a bad habit. The main reason is that the biological clock has been changed and a good schedule has not been formed. I suggest you go to bed on time and try to control the habit of watching your mobile phone before going to bed. Even if you can't sleep, close your eyes and lie in bed. Stick to it for a few days and you will gradually form the habit of falling asleep. In addition, you can also relieve fatigue through proper physical exercise, which makes it easier to fall asleep as soon as possible.
