1, too high or too low pillow will be bad for cervical spine.
Too high a pillow will cause the cervical spine to lean forward, and a certain part of the cervical spine will be excessively compressed, which will destroy the normal physiological forward bending angle of the cervical spine and compress the cervical nerve and vertebral artery, causing brain neurasthenia such as neck pain, head hypoxia, headache, dizziness, tinnitus and insomnia.
2, high pillows will affect the quality of sleep.
If the head is too high on the soles of the feet during sleep, the blood supply to the brain will be reduced, the blood oxygen supply will be poor, and the brain will not get enough rest. Over time, there will be adverse consequences such as mental fatigue, decreased energy and reduced work efficiency.
3, the pillow is too high to be stiff.
Too high a pillow is not only easy to cause cervical spondylosis, but also easy to cause stiff neck during sleep. Many patients with stiff neck are because the pillows they sleep on are too high.
4, low pillow is prone to blood supply imbalance.
Putting a pillow on the ground or not putting a pillow will make people lean back too much when lying on their backs, which will easily lead to uneven blood supply, congestion and swelling of nasal mucosa, which is very sensitive and will affect breathing when swelling. And it is easy to open your mouth and breathe, which leads to dry mouth, sore throat and snoring.
If you don't lie on your side with a pillow, the neck muscles on one side will cramp and ache due to overstretching and fatigue, resulting in "stiff neck".
5, the pillow is too low and prone to bone hyperplasia.
If the pillow is too low, the neck will not relax, but will destroy the normal curvature of the cervical spine. Therefore, too high or too low a pillow will affect the cervical spine and cause various neck symptoms.
6. Optimum height of pillow
Generally speaking, the height of the pillow is 10- 15 cm, and the specific size depends on the physiological radian of each person, especially the physiological radian of the neck. People with broad shoulders and fat bodies can have a slightly higher pillow, while thin people can have a slightly lower pillow.
7. How to judge whether the pillow is too high or too low?
If the pillow is too high, it is likely that your pillow is too high, such as neck pain, headache, dizziness, tinnitus, insomnia, or numbness in your hands and feet during sleep.
If the pillow is too low, if you don't drink water before going to bed, but you wake up and find your face swollen, it may be that the pillow is too low and your head is slightly congested. If the pillow is too low, the chin will be lifted up, and it is easy to open your mouth and breathe, leading to snoring.
8, the hardness and elasticity of the pillow
An excellent pillow, the contact area between the head and the pillow is small, the local pressure is high, and it is uncomfortable to sleep.
If the pillow is too soft, the head will sink in, which will affect blood circulation, make the head numb and easily cause neck muscle fatigue.
The elasticity of the pillow should not be too large, otherwise the neck will be very tired and it will easily cause neck muscle damage.
