It is said that sleeping the next day after staying up late can't make up for it. What about the sleep time of those who emigrated in reverse?

There is a biological clock in the human body. If you don't sleep at night, sleeping during the day will disrupt the adjustment of the biological clock. It makes people feel tired.

But when you immigrate, the first day and the second day, you have to get jet lag.

After the jet lag, you will feel at home.

Although it's daytime on the other side of the earth, it's night here, which is a fact. You're not. You fly around every day.
