People spend at least one-third of their lives in sleep. Infants and children and patients who are bedridden for a long time are relatively longer. In this long years pillow shape, size, height, hardness and sleep posture will have a great impact on human health. Pillow, the necessary thing to sleep. Everyone is used from childhood to grow up, anyone who feels they are “experienced”, know what pillow they are used to, know what pillow they like. But the habit and favorite may not be the most suitable. The second Chinese hospital in Guangdong Province, acupuncturist Nie Bin said, long-term use of unsuitable pillows will cause a series of chronic strain injury, and even develop into cervical spondylosis. Therefore, know how to scientifically select the right pillow, only really in line with the way to sleep and health. A pillow “head” also pillow “neck” “long-term use of unsuitable pillows, cervical curvature changes, resulting in cervical instability, ligament damage, joint misalignment and other chronic strain injury, and over time develop into cervical spondylosis. ” Xu Xuemang said that a suitable pillow is conducive to maintaining the normal cervical curvature of the human body, improve the quality of people’s sleep, to ensure that the next day energetic. In daily life, on the cervical spondylosis caused by pillow discomfort is a frequent occurrence. One day a patient came to the hospital to see me, said neck pain for a long time, often wake up in the morning and feel sore neck, asked her some habits, as well as the emergence of neck pain time and way, ruled out some related diseases, probably more sure in mind because the pillow is not suitable to cause, asked her pillow is not too high, her answer is also as I guessed, and her long-term high pillow also So that the physiological curvature of her cervical spine straightened, can not help but feel sorry, because this situation is completely avoidable. Then people can not help but ask, what is suitable for their own pillow, is not the more expensive the better, or the lower the pillow the better? First of all, it should be clear that the pillow is not literally understood only pillow “head”. Interpretation of the name” said “pillow, check also, so check the item also”, meaning that the pillow is used to support the cushion, restraint neck. So the pillow, not only the pillow, pillow neck also. In supine, the highest point of the pillow (pivot point) should be in the middle of the neck (equivalent to the 4th cervical vertebrae), so that the pillow, the neck while the pillow to support the neck curve, maintain the physiological curvature of the pillow neck, stabilize the cervical spine; side lying, the pivot point of the pillow is located in the middle of the side of the neck, the head should be slightly lower, so that people feel comfortable and easy to sleep. Second, the size and height should be appropriate pillow size: on the one hand, the pillow filling is not too full, about one seventh or eighth of the capacity of the pillow can be, in order to facilitate the adjustment of the height, easy to use when supine, side lying change position; on the other hand, the area should be moderate, the general length of about slightly wider than two shoulder spacing, the width of about from the occipital bone to the first thoracic vertebrae, that is, to maintain the physiological curvature of the cervical vertebrae convexity, but also play a braking effect. Pillow height: pillow height should not be too high or too low. The pillow is too high to cause cervical spine recoil, will make the neck pressure is too large, causing insufficient blood supply to the head and neck, hypoxia ischemia, headache, dizziness, tinnitus, insomnia and other symptoms, in fact, high pillow is not worry; pillow is too low to cause cervical spine straightening, also easy to cause blood supply imbalance, causing congestion and swelling of the nasal mucosa, and then affect breathing, easy to appear chest discomfort, and even induce cardiovascular accidents. The appropriate pillow height to maintain the normal physiological curvature of the cervical spine. Some studies have shown that, according to the Chinese physique, the appropriate height of the pillow should be – three, supine position → head back pillow 6 ±, neck pillow 11 ± side lying position → side of the face pillow 13 ±. Of course, this is not absolute, there are also individual differences, should be fine-tuned according to individual differences. Fourth, the pillow material selection to science Generally speaking, the pillowcase fabric to cotton is optimal, that is, soft, dry, breathable, warm, can fully absorb sleep sweat, moisture, keep the neck dry, comfortable. And science, good pillow core texture should be soft feeling, moisture absorption, and can cushion the head constantly subject to the role of the applied elasticity. Pillow commonly used materials are quite a few, such as duck down, buckwheat bark, green tea, Chinese herbs, etc.. But the market choice of pillows, there are strict indications, should be used under the guidance of a physician to choose. Such as chrysanthemum pillow, chrysanthemum sex pungent cool, the function of pacifying the liver and submerged Yang, clearing the liver, dispersing wind heat, for liver Yang hyperactivity type hypertension see headache, dizziness, etc.; and Chuanxiong pillow, Chuanxiong sex pungent warm, moving qi and blood, adapt to qi stagnation blood stasis type cervical spondylosis see neck pain, dizziness, hand numbness, etc.. In general, the so-called good pillow, not expensive pillow, high pillow. The scientific appropriate pillow comfortable when sleeping, no discomfort after waking up, is to prevent cervical spondylosis “simple, convenient, inexpensive, test” method.
