Sleep direction. Sleep with your head facing north and your feet facing south. The human body is influenced by the earth's magnetic field anytime and anywhere, and the brain is also disturbed by the magnetic field when sleeping. When people sleep, they take the posture of head north and feet south, so that the magnetic field lines can pass through the human body smoothly and minimize the interference of the earth's magnetic field.

Sleeping posture. Sleeping like a bow is effective, and lying on your side is light. Studies have shown that "sleeping like a bow" can just reduce the force of the center of the earth on the human body. Because people's hearts are mostly on the left side of the body, lying to the right side can reduce the pressure on the heart.

As for Chinese medicine, there are countless phenomena that are contrary to modern scientific explanations. Traditional Chinese medicine and western medicine have different theoretical bases, so they cannot be required to have the same specific views at any time and at any level. In addition, we should not just look at one sentence of TCM, but understand it in the whole theoretical system. In short, this is a question that puzzles scientists. The development level of modern science is not enough to clearly explain who is the best, and the earth's magnetic field is just a general speculation without strict argumentation. What we ordinary people have to do is to sleep where there is no wind.
