Physiologically speaking, people are not nocturnal creatures, that is to say, even if you use jet lag to make your life black and white, sunlight will still make your brain judge day and night, and then your body will make your functions more active during the day and more sluggish at night according to time. And you work at night and sleep during the day. This inversion will lead to physical dysfunction and endocrine disorders. If you can't change jobs, I suggest adjusting the time of eating and drinking. For example, three meals should be served as soon as possible, and midnight snack should be served as soon as possible. For example, don't work immediately before one o'clock and after midnight snack, rest for half an hour to relax, sleep as tightly as possible during the day, and don't rest immediately after Chinese food with a shade cloth. It is best to stand 15 to 30 minutes. In short, this kind of life is still unhealthy. I hope you can get rid of it as soon as possible.
