At least one-third of a person's life is spent in sleep. Infants and young children who stay in bed for a longer period of time are relatively longer. The shape, size, height, hardness and sleep posture of the pillow during this long period of time will have a great impact on human health.
The direct contact with the pillow is the cervical vertebrae of the human body, and the cervical vertebrae are closely related to the shoulder and lumbar muscles, ligaments, intervertebral discs, etc. of the human body, thereby showing the influence of a suitable pillow on human health. Students and computer families should pay more attention to the selection of pillows.
Determine the appropriate height and hardness
In addition to focusing on the internal filling of pillows with different characteristics, the most important thing is to determine the height and hardness of the pillow that best suits your body's actual situation. Sleep habits also have a subtle effect on the height of the pillow, and should be considered together. For normal people, the height and hardness of the pillow are related to each person's fat and thin, shoulder width, neck length, and comfort.
If a normal person sleeps too high on a pillow, whether it is lying on his or her back, it will change the physiological curvature of the cervical spine. Over time, the muscles of the neck will be strained and paralyzed, accelerate the deformation of the intervertebral joints, and promote the formation of bone spurs, leading to instability of the cervical spine. And other issues.
In addition, the high pillow will increase the angle between the neck and the chest, so that the tracheal ventilation is blocked, which may lead to dry throat, sore throat and snoring.
