Can Pillow Height Effect the Body Pressure Distribution and Sleep Comfort: a Study of Quinquagenarian Women

A proper sleeping pillow can relax the neck muscles during sleep, yet does not impose stress on the spine or other tissues. By analyzing the different body pressure and subjective comfort evaluation of quinquagenarian women with different pillow heights (3cm, 7cm, 11cm and 15cm), this paper found that as the pillow height increased, the neck contact pressure, contact area and force increased at the same time, as well as the peak force and peak contact pressure gradually shifted from the head to the hip area. It was shown that the pillow with a height of 7cm was the most comfortable for supine positions.
