I just watched TV and said that due to the relationship between the earth's magnetic field, people can grow taller by placing their beds in the north-south direction. Is this true?

In home feng shui, the most talked about is the direction. When it comes to this topic, many people will think of words such as green dragon and white tiger. In fact, this involves a geographical issue, and there is nothing too deep. secret.

1) The orientation of the azimuth is related to the earth's magnetic field. We know that the earth is not completely round, but has a slightly rounded shape, and the magnetic field has an impact on the blood flow of the human body. This will have an impact on human health.

2) The direction of the azimuth is also related to the angle of light between the sun and the earth. Under certain conditions, it will also affect indoor lighting and have an impact on people's psychology.

In fact, some very common Feng Shui teachings are correct to a certain extent. As long as people with a high school education, it is not difficult to analyze the reasons from a scientific perspective. Let’s try to analyze it using very simple scientific knowledge:

1) The headboard of the bed should not be placed in the opposite direction. This is obvious, because the earth rotates from west to east, which will affect the blood flow to the brain, thereby affecting sleep health.

2) It is not suitable to press the beam on top. This is a psychological question. There is a saying in Chinese painting that the sky is thin and the earth is thick. There is a beam above the head, which obviously creates a sense of oppression in people.

3) Don’t get too close to the window. In fact, there are two problems when approaching windows. One is that the sound insulation performance of windows is lower than that of brick walls. When sleeping at night, the noise heard by people will be louder than if they are farther away from the window. Another window is a source of light, which can affect a person's sleep.

4) It is not advisable to face the mirror. This is actually an obvious psychological problem. Looking in the mirror in the bedroom at night will always give you an eerie feeling, which is even more obvious when the bedroom uses table lamps instead of fluorescent lamps.

5) It is not suitable to face the door. What problems will occur if a person sleeps facing the door? This involves an issue of psychological safety. Just as we sit on a stool with our back to the door, and we sit with our side facing the door, the feeling is different.
