When people sleep, which direction should their heads face?

Sleeping with your head facing south or north and south is good for your health. Our traditional residential buildings pay attention to sitting north facing south; Indoor beds are usually placed in the east-west direction. Because the earth is a big magnetic field, the magnetic lines run through the north and south.

The water molecules in the human body are like a small compass, constantly swinging under the action of the earth's magnetic field lines. When the poles of water molecules are in the same direction as the magnetic field lines between the north and south of the earth, the water molecules stop swinging and tend to be stable; When the polarity orientation of water molecules is different from the magnetic field lines between the north and south of the earth, water molecules will be unstable. If people's sleeping direction is north-south, then the direction of water molecules, people's sleeping direction and the direction of magnetic lines in the north-south direction of the earth are the same, so people are the easiest to fall asleep and have the highest sleep quality.
