At the same time, choose the shape of the pillow. The ideal pillow shape should be low in the middle and high around, so as to maintain the normal curve of the cervical vertebra, thus protecting the cervical vertebra and keeping it relaxed.
Long-term use of the pillow is too high, which will change the physiological curvature of the cervical spine, make the neck muscles in a state of fatigue for a long time, and may also cause traction strain of ligaments, resulting in spasm or inflammation, which will cause patients to have numbness in their hands, neck and shoulder pain, dizziness and other symptoms. At the same time, high pillows can also cause cervical spondylosis and stiff neck.
Some people don't choose pillows, their heads are tilted back too much, and when they sleep, they will open their mouths and breathe, resulting in sore throat, dry mouth or snoring. If you lie on your side for a long time without a pillow, your neck muscles will be in a state of fatigue and spasm for a long time, which will cause neck pain.
Too low a pillow will lead to uneven blood supply, which will easily make the patient's sick facial membrane in a state of congestion and swelling for a long time, which will affect breathing and make the neck and shoulders ache.
