Why do you get sleepy at five or six in the morning when you work the night shift? I get off work at eight.

Normal people sleep soundly around three in the morning.

People who work the night shift, around five or six in the morning, their biological clocks have reached the brink of collapse, and they are sleepy at this time! If you have a bed, or don't go to work directly, you fall asleep and no one wakes up!

Once you get through five or six o'clock and seven or eight o'clock, people will recover. However, at this time, I feel that my mind is not clear enough and my resistance is seriously reduced!
