Pillow too high is not conducive to sleep and health reasons is that the human neck has a certain natural curvature, if the pillow is too high, will make the neck muscles, ligaments in a state of tension for a long time, easy to cause fatigue, leading to pillow. And if long-term use of high pillow, easy to aggravate the cervical spine osteophytes, causing numbness and soreness in the neck and shoulders, and even affect the blood supply to the brain, dizziness, vertigo and other symptoms, so cervical spondylosis patients especially should not use too high pillow.

The pillow is slightly longer than appropriate, the length of the pillow should be enough for the head to turn over a body position during sleep. Pillow should not be too wide, to 15 ~ 20 cm is appropriate, too wide easily lead to the head and neck joints, muscle tension.

Soft and hard suitable

Pillow suitable for soft and hard moderate, to slightly elastic for good. Pillow is too hard, will make the head and neck and pillow contact relative pressure becomes large, causing head discomfort; pillow is too soft to maintain the normal height, the head and neck can not support easy fatigue.

Filling material suitable

Pillow raw material variety. For example, stone, bamboo, board, fabric, cotton, cotton, mung bean bark, buckwheat bark, cassia seeds, down, chemical fiber products, etc..

Most people are willing to use down pillow, because of its soft, comfortable, durable, but the breathability is not good, easy to sweat people should not use, with a long time easy to plate, not fluffy. Cassia pillow can be massaged on the head and neck, long-term use has a laxative, bright eyes, anti-insomnia effect.
