Because the human cervical spine itself has a certain curvature, just like a curved banana, when the head is low, the cervical spine will lose its curvature and become straight. Experiments show that when the human body stands upright, the pressure on the neck is about 4~5 kg, and once the head is lowered, the pressure on the neck will increase sharply with the increase of bending angle, and when it is bent to 60, the pressure will almost reach 30 kg.
