What do pillows do for people?
The so-called physiological radian is a smooth, front facing arc formed by the 7 vertebrae, and the function of the pillow is to maintain the normal physiological curve. How to maintain normal physiological radian, it is necessary to see whether you choose the pillow height, soft and hard size is really clear. Improper choice of pillow, directly affect people's sleep. So what kind of pillow is the right size? The old saying that "sit back and relax" is not scientific. The pillow is too high, no matter what position to sleep, can not maintain the normal cervical lordosis of cervical curvature, will increase the burden, may lead to stiff neck.
I feel the same way, but it is said that pillow without pillow is bad for health. A pillow designed for human mechanics is not only beneficial to the cervical spine, but also to the physiological curvature of the spine and the muscles around the spine. The disease comes from the spine, spine, and regular care, so as to maintain good health. The role of pillows is to ensure that the physiological curvature of the neck does not change during sleep. Experts, the cervical spine is located in the upper end of the body spine, wrapped in the neck, composed of 7 vertebrae.
If the neck pain, headache, dizziness, tinnitus and insomnia neurasthenia and so on, or sleeping until half feel numb hands and feet, it will be your pillow is too high; can make the head congestion pillow is too low, easy to cause the eyelid and facial edema, and the jaw will therefore lift up, easy to mouth breathing, snoring. If your neck and shoulders become sore after waking up, it's too low and not too soft to use pillows or pillows. Experts pointed out that the best choice regardless of supine sleep, side sleep can maintain the normal physiological curvature of the neck pillow. Adults with supine height of 15~20 cm pillow, side sleeping pillow height of about 20~15 cm height is appropriate. Since each person has different cervical vertebrae, it is probably our best choice to tailor different health pillows. It takes time to choose a pillow that fits, and a good pillow adds a safe pillow.
