It is generally recommended to face north and south, because the earth's geomagnetic field will attract some metal substances, which are contained in the human body, especially in the blood. So if you sleep from east to west, it will lead to insomnia and dreaminess, which will affect the quality of sleep. Generally, it is in the north-south direction, which can make the body organs in an orderly state and improve the function of organs. After a long time, qi and blood can run smoothly, and it can also coordinate the slow-wave fast broadcast of sleep, which can deepen the sleep depth.

As for the direction of sleep expressed by professional medical experts, there is generally no corresponding statement in the professional field, and no research paper shows that it will affect the quality of sleep. Even if it has an impact, it is still very small. This is just a psychological hint. Generally speaking, environmental factors, psychological factors and physiological factors will affect the quality of sleep. Although there will be a wide range of magnetic fields around us, for example, in thunderstorm weather, electric fields will be generated in the air, and the earth's geomagnetic field will generally face north and south, but this will not have much impact on personal health.

If you sleep in the north-south direction, it will contribute to human health, effectively avoid insomnia and dreaminess, and will not affect the quality of sleep. However, after investigation by professional doctors, it was found that this was nothing more than a psychological suggestion. Even if there is a magnetic field, it has little effect on sleep, and the factors affecting sleep quality are mainly psychological factors, environmental factors and psychological factors.
