Let's talk about taking a nap first, because people will feel sleepy after eating at noon because the stomach will peristalsis and blood will enter the stomach, so people will have great cerebral ischemia. Therefore, it is most appropriate to take a nap for half an hour after lunch at noon (it will lead to gastroptosis after eating), and it is generally appropriate to sleep for half an hour to an hour. In the afternoon, the manager is full. Long sleep can easily lead to confusion of thinking or insomnia at night.

In addition, sleeping at night usually starts at 9: 00, because the liver meridian is working from 9: 00 to 3: 00 in the morning. If you sleep during this time, even if you get up at 4 o'clock, you will be full of energy and not tired. If you stay up late, even a day's sleep can't make up for it. Now people in big cities have more nightlife. If you can't sleep at 9 o'clock, you must sleep at 1 1. Liver meridian purifies and produces blood. If you don't sleep during this time, the liver meridian will not work normally and the dirty blood will not be removed in time. This is why people who often stay up late look pale. Health preservation is not as good as health preservation, so pay more attention to health knowledge. I hope it helps you.
