The height of the pillow varies from person to person, and the height of each person's fist is generally the height of the pillow for himself.This height coincides with the physiological flexion of the person left bed. When the person stands, the cervical vertebra has forward physiological radian, so if the head is too high or too low after lying down, it will cause the neck to be straight or inverted.The pillow is too high: the impact of sleep, and can not maintain normal cervical curvature, but also easy to add to the burden of cervical spine, stiff neck.Pillow is too low: can make head hyperaemia, cause eyelid and facial oedema easily, snore.
A large number of survey results show that, due to different shapes, when lying on the side, the difference of pillow height requirements of different people can reach more than 10cm. Even the same height, the shoulder width, head width, neck length varies, while lateral to the height of the pillow and the angle of the requirements are different. Therefore, it is very important to have an accurate sleeping pillow which can adjust the height and the angle exactly according to the different body types! The height adjustable sleeping pillow is the world's only accurate precise matching of different size, and physiological curvature of cervical vertebra gradual adjustment, while the general pillow height can not be adjusted, easy to cause cervical spine injury.
When you lie on your back and on your side, the height of the pillow can not be the same. Medical anatomy and X light medicine clinical research shows that: Based on the people in the supine head does not need a pillow, but need to hold the neck to maintain cervical curvature, but the side, to make up for the distance between the shoulder to the head, you will need up to 12-25cm (due to different size and different height) and the height of the pillow. Must be use compressed height, such as height of 160-170cm adults need about 18cm height in the side, height 150-160cm adult side need about 16cm height, otherwise, it will inevitably lead to the insufficient height of cervical lateral distortion. So far, all the pillows sold on the market in the world, except for China's accurate sleeping pillow, do not have a high degree of compression when using 10cm. When lying on the side, it will inevitably lead to lateral distortion of the cervical spine!
