Does the cold water pillow hurt people?
If the water pillow temperature (for example, it is electronic constant temperature water bed can be used for a long time, especially in winter. People can help you can use preheating vessel).
Healthy use of pillow RaidersDirect contact with the pillow is the body's cervical spine, and the cervical spine and the shoulders of the human body, and the waist muscles, ligaments, intervertebral disc and so closely related, it can be seen that the right pillow for human health impact.The cervical spine has a lordosis, called physiological lordosis, which is the most comfortable in any case to maintain the natural physiological radian. When sleeping, the normal physiological lordosis of the cervical vertebra should be maintained so as to meet the physiological requirements of the cervical spine. The role of the pillow while sleeping mat in the head and neck below, so that the cervical vertebra to maintain normal physiological radian when people sleep can, and make the neck skin, muscle, ligament, intervertebral disc, intervertebral joint and through the neck of the trachea, esophagus, nerve tissue and organs during sleep, together with the entire body to relax and rest.The pillow can not only well supporting the neck lordosis, but also can well accommodate the head occipital (back) kyphosis, because of backward protruding occipital skull, only in this way, the various tissues and organs would in a relaxed state of rest. Improper pillows and incorrect sleep positions can cause neck ligaments and muscle tension to increase, accelerate the degeneration of the intervertebral joints and cause functional disturbances.
The water pillow without constant temperature protection, use for a long time, will cause the blood vessels of the head temperature is too low, a long time even the head will produce paralysis effect (I have tried), and will produce what disease, temporarily don't seem to study the mechanism. Therefore, recommend the use of time not to exceed 8 hours (if it is not flesh Wang, the use of time not more than 3 hours).
