I choose this according to my physical condition. I used to work in shifts. I have a normal meal in the morning, then go to bed and have lunch after waking up. Usually eat a little at 8 pm, not much. I eat some bread and biscuits at one or two in the middle of the night. In short, long-term night shift will also form your own biological clock. It is most important to find a way that suits you, but it is not recommended to work all the time at night, because it is really tiring and not conducive to your health.
