At present, we may know the importance of the cervical health pillow, many people have begun to use the cervical health pillow, but the market is full of cervical health pillow which is more suitable for you, you pillow in the end the pillow did not, the following we will come one by one. The first question: why do we need to pillow cervical health pillow? For the cervical spine, one of the most important things is called curvature, because our normal cervical spine is like the right side of the picture below, and many of us go to the medical checkup may have often heard of physiological curvature straightening of the word, the so-called physiological curvature straightening is like the middle of the picture below and the left side of the same. Why there will be so many physiological curvature straightening, the biggest reason is that with the emergence of smart phones, we have developed the habit of often low head, often low maximum harm will make the cervical spine to withstand greater pressure, someone once did a test, when the cervical spine flexion of 60 degrees, the cervical spine will be subjected to nearly four times the weight of the head, which is the cervical spine in advance of the aging of the intervertebral discs, an important reason for the protrusion of the discs. And one-third of our life are sleeping, so through the sleep posture adjustment to restore the cervical curvature becomes very important, the following Dr. Zhu will tell you how to choose the right pillow for yourself? First of all, we sleep in three positions, one is lying on the back, one is lying on the side, and one is lying on the top, we adopt the sleeping habit of lying on the top position should be a minority, and it is not recommended to sleep on the top, because lying on the top will make your cervical vertebrae rotate in one direction, causing excessive pressure on the cervical vertebrae small joints, so the recommended sleeping positions are lying on the back or on the side. When lying on the back, the most important thing is like the picture on the left, the pillow to the shoulders below, not to the back of the head position, you can imagine, when the pillow to the back of the head after the cervical spine is still in the low position, and can not restore the curvature of the cervical vertebrae, so only when the pillow to the shoulders below the cervical vertebrae curvature can be restored. When lying on the side, the most important thing is the height of the cervical spine, according to my observation, a lot of pillows in the side when lying on the height will be too low, when the height of the cervical spine is too low when the cervical vertebrae will form a sideways curved posture, which is also extremely incorrect, will make the cervical vertebrae on both sides of the muscle strength of the long term is not balanced, inducing a variety of cervical spine diseases, and the most appropriate height is half of the width of the shoulders, and the best way to lie down in their own pillows to try it out, so lie down! And side lying for the pillow is equally important. A good pillow will allow your cervical spine to get enough rest, and can correct your cervical problems during sleep, so the right pillow is very very important.
