Sleeping during the day and working at night are all staying up late. . If you have to say that the biological clock sleeps at night, it doesn't count. Then don't we immigrants stay up late every day?

How to explain it? Clocks are caused by long-term living habits. If you work abroad during the day and rest at night, it's not called staying up late. Although black and white are reversed in foreign countries, as long as you work and rest in full accordance with the time there, it will not be called staying up late after a long time, and your body will be adjusted. But in China, I sleep during the day, work at night and even stay up late. Why do you say that? Because in 365, I couldn't sleep during the day and had to go to work at night. What about holidays? Doesn't that mean you have to work during the day and sleep at night? In this way, you can't arrange your sleep completely according to daytime sleep and night shift, and then your biological clock will go wrong. Moreover, sleeping during the day is very noisy, and someone looking for it will definitely affect the quality of sleep, which is definitely different from the quiet sleep quality at night. Therefore, sleeping during the day and going to work at night are counted as staying up late, and emigrating abroad during the day and going to work at night is not counted as staying up late, even if black and white are reversed at home and abroad.
