First of all, let's take a look at which geographical position the bedside faces, which is good for the human body. It is generally believed that the bed should be placed in the north-south direction, because the geographical magnetic field is in the north-south direction, ensuring that the sleeping direction of the human body is consistent with the direction of the magnetic field lines can make people fall asleep more easily. The head of a bed is facing the taboo of geomantic omen, on the contrary, it is considered very unlucky to face the west. The west has always been regarded as a paradise, where people die after death, and it is very unfavorable for the living to face that direction. And the east-west direction is the direction of the earth's rotation. If you sleep in the west, your blood will often collide with your head, making your sleep unstable.
In addition, it is emphasized that the bedside of Feng Shui cannot be hedged with the door. If the head of the bed is facing the door, anyone who goes in will glance at the situation on the bed, and there is no privacy at all, which will affect the rest of the people on the bed. Moreover, the people in the bed can't see the situation at the door and feel unsafe. The head is often caught by the wind at the door, and it is also easy to induce headaches and other diseases. The head of the bed is facing the geomantic omen, and it is also important not to be empty, that is to say, it is better for the head of the bed to face the wall than the window, otherwise there is nothing behind it.
By the way, the bedside should not face the toilet, kitchen, sewer, stairs, etc. These places are either places where the airflow is very unstable or dirty and unsanitary, which is not conducive to human health.
