In the clinic, often encountered many cervical spondylosis patients said: “doctor, I originally sleep relatively high pillow, and then after the emergence of neck pain, read newspapers and books or listen to friends said that sleeping on a high pillow will get cervical spondylosis, changed to a lower pillow, and even spent hundreds of dollars to buy a health pillow, but now the neck pain not only did not reduce, and often in the middle of the night hand paralysis “. Why is this? We first understand the physiological structure of the normal human spine, the normal human spine from the front is straight, if curved, it is not normal, medically called scoliosis, is in need of treatment. From the side, however, it is not straight, but consists of many curves, of which the physiological curvature of the neck is forward curvature, the chest is backward curvature, and the waist is also forward curvature. If the physiological curvature of the neck becomes straight, it is also abnormal. This is why when many cervical spine patients go for cervical spine X-ray, the report sheet often says that the physiological curvature of the cervical spine is straightened. In modern society, due to the application of computers and the increase in the time spent working and studying, we often bow our heads, and often bowing our heads can easily straighten the cervical spine. The straightened cervical spine is prone to neck pain and weakness, and even dizziness and hand numbness. So can the often straightened cervical spine return to normal bending? The answer is that it is possible, but not for everyone. Generally speaking young people, such as under 30 years old, cervical spondylosis is not serious, through treatment, exercise and daily reduce the time of head down, it is possible to straighten the cervical spine to restore the normal bending. The choice of pillow is very important. For normal people, if long-term sleep high pillow, equivalent to when we sleep low, will cause the cervical spine physiological curvature straightening, and easy to get cervical spondylosis. Low pillow, supine about 10cm high (according to each person’s body type to determine the appropriate increase or decrease,) is in line with the normal cervical physiological curvature, more healthy, the current market popular health pillow can also be. But note that this is for normal people, healthy people without cervical spondylosis or young people with mild cervical spondylosis. For the middle-aged and elderly who have cervical spondylosis (these people are often a high incidence of cervical spondylosis), how to choose a pillow? In addition to straightening of the physiological curvature, these people often have cervical spine osteophytes, narrowing of the spinal space and other manifestations when they take cervical spine X-ray. This kind of person cervical spine straightening, is formed over the years, has been relatively stiff, reversible poor, it is not suitable to sleep low pillow again. This kind of people sleep low pillow or health pillow is quite artificially caused by the head back. We often see in the clinic many cervical spondylosis patients are most afraid of head back, head back will cause neck pain hand numbness aggravated, and low head instead of pain. Why is this so? From the anatomical point of view, we know that for the cervical spine with degeneration, such as cervical spine osteophytes, the narrowing of the intervertebral space caused by disc degeneration and herniation, if the head is tilted back, it will cause the nerve root canal (the exit of the nerve root, where the narrowing will cause the hand paralysis we usually see) or the spinal canal accommodating the spinal cord to become even narrower, thus aggravating the clinical symptoms, so for such patients, I often teach the patients to increase the height of the pillow or maintain the original Therefore, for such patients, I often teach them to increase the height of the pillow or maintain the original pillow height, which can make the nerve root canal and spinal canal wider and thus can relieve clinical symptoms, and it is not appropriate to lower the pillow again. There is also a part of the middle-aged and elderly people without cervical spondylosis, may take X-rays will have cervical physiological curve straightening, but no discomfort, such people also do not need to adjust the height of the pillow to prevent cervical spondylosis, you just need to maintain your original pillow height, unless the special high pillow people, can gradually reduce the height of the pillow, but never too much at once, otherwise you may get cervical spondylosis. For people who sleep mainly on the side, the height of the pillow for your shoulder to the height of the head, that is, when sleeping neck to maintain a neutral position can, in general, will be higher than the supine people pillow. As for the hardness of the pillow, generally speaking, the best soft and hard, too soft and too hard pillow are not very suitable. Many people and even orthopedic surgeons are not clear on the above, often think that a simple low pillow can prevent or treat cervical spondylosis, in fact, from the above we can know, if you are still young, and no obvious cervical spondylosis, choose a low pillow or health pillow it; but if you are not young, or already obvious cervical spondylosis, low pillow may not necessarily suit you, ” The “high pillow” straight can make you worry-free.
