In our daily life, sleep can be said to occupy most of our time. If there is no way to ensure adequate sleep, then whatever you do the next day will be very inefficient, so it is very necessary to keep adequate sleep, and modern people's life pressure is too great, and staying up late is becoming more and more common. But in fact, the harm of staying up late is very great. With the growth of age, body functions will begin to age slowly, and staying up late will accelerate the aging of body organs.

Old people often say that if you don't choose the right pillow, the more you sleep, the more tired you get. Sleep first, then sleep, and sleep beautifully. Head windward, warm, feet windward, please. Don't sleep in the alley, cross-flow is the most poisonous.

Don't turn on the light when you sleep, and don't get dizzy when you get up early. If you want to sleep easily, don't face west to east. Learn something when you sleep. You can't sleep with your feet facing west and your head facing east. There may be no scientific evidence to prove it directly for the time being, but the wisdom of working people should not be underestimated.

When people build houses, they will choose to build in the direction of north facing south. Such a house can maximize lighting and shelter from the wind. People in China are divided into yin and yang, and the mountains in the south and the water in the north are yang, and vice versa. Harmony between Yin and Yang is the behavioral characteristic of China people. Now in the northern countryside, the same is true of the heatable adobe sleeping platform built at home. Most of them are north-south oriented, and east-west oriented houses are rarely seen, because the magnetic field of the earth is distributed at the north and south poles. If something falls asleep, it will be disturbed by some kind of magnetic field.

It has certain influence on human cells and physiological functions. Some people who sleep in the right direction may have poor sleep quality and unstable sleep, which may lead to insomnia and so on.

However, our own magnetic field is very weak. If we sleep in the north and south, it is just along the geomagnetic direction, which is beneficial to human health. Maybe this is the magnetization effect of human body. Although we haven't fully understood nature and explained the strange phenomena in this world. But follow the laws of nature, live in harmony with nature and fear nature.

In order to better survive in the embrace of Mother Earth, the ancients have taught us this truth with their words and deeds, which is the crystallization of their wisdom and an invaluable treasure left to us.
