Before introducing the correct sleeping posture, we first understand two common sense concepts: first, the human spine has its own special physiological curvature, including cervical and lumbar curvature; second, under normal circumstances, the human muscles, tissues and bones should avoid prolonged incorrect posture to prevent repetitive compression injury (RSI). On the basis of these two concepts, we introduce the concept of correct sleeping posture: the ideal sleeping position should maintain the normal physiological curvature of the spine and ensure the natural relaxation of the muscles of the whole body. Otherwise, 8 hours of sleep plus years of repetition can cause spinal pathology or acute injury or discomfort, such as the fallen pillow. Correct supine sleeping position Sleeping on your back is the sleeping position recommended by many doctors, because it can better maintain the natural curvature of the spine, suitable for people with cervical or spinal pain. Flat sleep (supine), the pillow should be just from the whole head to the neck, not to the shoulders, not only to the back of the head half of the place, it is best to place a small pillow under the knee; correct side sleeper side sleep height should be doubled, between the two knees should also be a small pillow. Right-side sleeping position: the heart is located on the left, it is true that the pressure on the heart is less, conducive to blood flow and digestion of food in the stomach, but it is also said to be easy to cause acid reflux and sagging skin. Left-sided sleeping position: Although it is conducive to the discharge of gastric contents into the lower digestive tract to help digestion, however, the left-sided lying position compresses the heart and stomach, which can easily make people sleep unstable. In the choice of side lying position, should often change the side lying left and right direction. As a result of long-term taking a side lying position, it will make the spine force imbalance, and is not conducive to the treatment and rehabilitation of cervical spondylosis. Prone sleeping position As the body lies on its back, the head to one side, which is obviously extremely unfavorable to the balance of the neck and physiological curvature, and affect breathing. Therefore, prone sleeping is not a healthy and unscientific sleeping position, must be corrected. How to properly nap for many white-collar workers, nap is a luxury, most companies do not provide lunch break time and conditions, can only lie on the table to take a nap. Can wake up, hazy eyes, blurred mind, neck pain and back pain, so uncomfortable. To avoid the occurrence of cervical and lumbar spondylosis, really need to nap, it is best to sleep on the table pad a soft pillow; or adjust the height of the chair, reduce the upper body down amplitude; and should not sleep for a long time. In addition, you can train to sit and sleep, sit and sleep better than sleeping on your back, it is best to choose a high-backed chair, bring a U-shaped cervical pillow, so that the cervical spine has to rely on, that’s better. The choice of pillow when sleeping How to properly pad the pillow is very important when sleeping, the pillow must be padded to the neck. We can self-test, when lying down, the lowest chin if towards the sky, that the pillow is too low, if the chin downward pressure, that is, the pillow is too high, the chin should remain horizontal, is comfortable and the correct pillow height. There are many people used to not pad the pillow, when sleeping head will be tilted back, the cervical spine to bear the pressure than when tilted forward is twice as high, long-term down, will certainly be a problem. As for the height of the pillow, young people can be slightly lower, older to slightly higher.
