Will the headboard of the bed affect my health?

Generally speaking, it is good to face the north-south direction, so that it follows the direction of the magnetic field lines of the earth's magnetic field, which is good for the human body. But what are the benefits, and how much they are, no one seems to have really studied them.

Generally, in the northern region, most of the buildings are oriented to the north and south, and this layout determines that the bed can only be placed in the east-west direction, which is contrary to the saying that it follows the magnetic field line, but I have not heard of anyone who is so bad.

So, you can face wherever you like, as the little monkey said, generally not facing doors and windows, this is just to prevent the head and feet from the wind, and there is no other reason.
