1. It is best to place the head of the bed facing the south. According to science and Feng Shui, there are positive and negative yin and yang magnetic fields at the north and south poles of the earth, which will affect the blood circulation of the human body. When a person sleeps with his head facing the south, it is often the most beneficial time for blood circulation. On the one hand, it can improve people's rest quality and get the best sleep.
2. On the other hand, it is also beneficial to human health. But if the south is a window, it cannot be facing the south, otherwise it is easy to get sick from the wind.
