The height of the most suitable pillow for sleep is more suitable in the range of 6~10cm. The specific size should be determined according to the physiological characteristics of each person and the physiological curvature of the neck, so as not to twist the neck.
Generally speaking, for people who are accustomed to sleeping on their backs, the pillow should be the same height as their fist after compression; for people who are accustomed to sleeping on the side, the pillow should be the same height as their shoulder width after compression.
From a health point of view, the phrase “sit back and relax” is incorrect. A pillow that is too high cannot maintain the curvature of the cervical spine, which not only affects the quality of sleep, but also increases the burden on the cervical spine. In fact, a pillow that is too high or too low is not good for your health.
