1, the earth's magnetic field is north-south, so when sleeping, the human body should also be north-south, so no matter whether the head faces south or north, as long as the body keeps the north-south direction and conforms to the magnetic field, the blood circulation in the body will be smoother and the brain will be calmer, so the quality of sleep will be higher.
2. Although from a scientific point of view, it is higher to sleep with your head facing south or north, from the actual situation, the human magnetic field is relatively weak. When sleeping, the earth's magnetic field will not have a strong interference with the human magnetic field, and its influence is relatively weak, which is basically in a negligible state. That is to say, the north-south orientation is better when sleeping, but if you really don't like sleeping in the north-south orientation, you can't sleep, feel uncomfortable and can't sleep.
3. The orientation of the head will also affect the quality of sleep. If your sleep quality has been poor and you can't find the specific reason, you can try to change the orientation of your head.
