In home feng shui, the most talked about is orientation. When it comes to this topic, many people will think of words like Qinglong and Baihu. In fact, this involves a regional issue, nothing too deep. 1) is related to the earth's magnetic field. We know that the earth is not pure round, but a little round, and the magnetic field has an influence on the blood flow of the human body. This will have an impact on human health. 2) The orientation is also related to the light angle between the sun and the earth. Under a certain degree of goodwill, it will also affect indoor lighting and affect people's psychology. In fact, some very popular geomantic sayings are correct to some extent. As long as you are a person with high school culture, it is not difficult to analyze the reasons from a scientific point of view. Let's try to analyze it with very simple scientific knowledge: 1) Don't put the bedside in the west. This is obvious, because the earth turns from west to east, which will affect the blood flow in the brain, thus affecting sleep health. 2) Not applicable to beam coping. This is a psychological problem. There are clouds in Chinese painting, and the sky is thin and the ground is thick. There is a beam on the top of the head, which obviously produces a sense of oppression. 3) Don't be too close to the window. In fact, there are two problems when approaching the window. One is that the sound insulation performance of windows is lower than that of brick walls. When sleeping at night, people will hear louder noise than the sound away from the window. The other window is a light source, which will affect people's sleep. 4) Not suitable for looking in the mirror. This is actually an obvious psychological problem. In the bedroom at night, there is always a gloomy feeling in front of the mirror, especially when the bedroom uses a desk lamp instead of a fluorescent lamp. 5) It is not appropriate to face the door. What's wrong when people sleep in front of the door? This involves a problem of psychological security, just like sitting on a stool with our back to the door and our side to the door, we feel different. We can test it in a very simple way, sleeping in a place where you sleep soundly. The next night, you can blow the fan of the computer case at home directly at you, and then sleep with the fluorescent lamp on, and you will feel what Feng Shui is. There really isn't. You can find a room with mosquitoes without hanging mosquito nets, lighting mosquito incense and spraying mosquitoes for fear of water. I promise you will look pale in a few days. In short, the bed is the most scientific in the north and south. Head south and feet north or head north and feet south. Secondly, the head faces east and the foot faces west. "From a scientific point of view, the bed should not be placed in the east-west direction, because the earth itself has a geomagnetic field, which is north-south (divided into the South Pole and the North Pole). Magnetic field has the property of attracting iron, cobalt and nickel. The human body contains these three elements, especially the blood contains a lot of iron, so sleeping will change the distribution of blood in the body, especially in the brain, which will cause insomnia or dreaming and affect the quality of sleep.
