This is because the direction of the earth's geomagnetic field is north-south, and the magnetic field has the property of attracting metals such as iron, cobalt and nickel. The human body contains these three elements, especially the blood contains a lot of iron. Therefore, east-west sleep will change the distribution of blood in the body, especially in the brain, causing insomnia or dreaminess and affecting the quality of sleep.
Pay attention to the position of the bed.
It is best to put it on the bedside, which is close to the wall or physical objects. Because if there is a gap by the bed, there is nothing to rely on, and there is no backer. It is easy for people to feel insecure, and their mood will gradually decrease, which will affect their normal life.
Windows are the best place for air circulation. If you put the bedside against the window, it is bad for your health and easy to catch a cold. If the bedside is close to the window, people's energy is easily lost with the window, which is very unfavorable to the body. If you can't change the position of the bed, you can cover the window with thick curtains or shading cloth to reduce some influence.
