In theory, memory foam pillows are good for sleep, so why would someone feel uncomfortable sleeping on a memory cotton pillow? In fact, no one is not suitable for memory foam pillows!
Based on our understanding of cervical and cervical spondylosis, a good pillow needs to meet two basic conditions:
1. It conforms to the physiological curvature of the human cervical vertebrae and satisfies the curvature. It satisfies the free extension of the muscles without distortion, thus creating a basic environment with smooth blood circulation.
2. No pressure on the muscles. Only the pillow does not oppress the muscles, so as to ensure the smooth circulation of the blood as much as possible, and improve the comfort of the neck during sleep. Imagine that the pillow is pressed against the neck and the blood circulation in the neck can be comfortable?
Since ancient times, people have had the consciousness to satisfy the physiological curve of the human cervical vertebrae, and they have begun to make pillows of various shapes in order to conform to the physiological curvature of the cervical vertebrae.
For not stressing the muscles. This is more difficult. Generally speaking, the pillow is softer and does not compress the muscles, but the pillow is too soft, and the supporting force is not good. Once the pressure is deformed, the neck is distorted, and the natural extension of the cervical vertebra can not be maintained. Therefore, it is soft and supportive. This problem has always been solved badly. It is even an anti-physical concept. Because it can be supported physically, there must be a fulcrum. If there is a fulcrum, there will be a reaction force. unit.
However, the appearance of the memory cotton pillow is a good solution to the muscles without pressure – that is, to have support, to ensure that the physiological curvature is natural, and that there is no pressure on the muscles. Of course, what is said here is the kind of high-density memory cotton pillow. Generally, the inferior quality and low density are not much different from ordinary silk cotton pillows and down pillows. Those who have learned about high-density memory foam pillows know that high-density memory cotton pillows have good support, but they are very soft to lay on, and basically have no reaction force on the neck.
For a person with healthy cervical vertebrae, the pillows are very poor, and they can sleep very well, but we all know that in the past few years, because of lack of exercise, with more computers, cervical spondylosis and discomfort have begun to appear. Called “cervical muscle cervical spondylosis”, which is the initial stage of cervical spondylosis).
Once the person with problems with the cervical vertebrae is particularly picky about the pillow, it is the level that requires the pillow to “support and not force the muscles”. Therefore, with the experience of pon pillows, memory foam pillows are the most comfortable material pillows on the market.
Finally, the height of the pillow is very important for the individual. If you think that your pillow is not suitable, in addition to the soft and hard shape, the most important thing is the height. Be sure to choose a pillow of the right height.
