Pad lumbar pillow sleep is not good, the reasons are as follows: First, pad lumbar pillow sleep need patients always keep supine position, lumbar pillow can support lumbar vertebrae, so that lumbar vertebrae always maintain the normal physiological curvature, can relieve the lumbar muscle tension, better support lumbar vertebrae. But anyone in the sleep can not do long time supine position, and not change the sleep position, normal people in the sleep will regularly change the sleep position, from the flat position to the side position, and then from the side position to the flat position, the whole sleep process will continue to change the position, so the pad lumbar pillow can not achieve the purpose of the initial protection of the lumbar vertebrae; Secondly, the lumbar pillow will be in the side sleep position on the abdominal muscles caused by the undesirable squeeze, can cause abdominal muscle soreness, distension and swelling, and can be used as a support to the lumbar vertebrae. Can cause abdominal muscle soreness, pain, and even squeeze the internal organs caused by increased intra-abdominal pressure, causing digestive system dysfunction.
