Do you know what kind of pillow is most comfortable for sleeping？
Many people are using a pillow that is close to a rectangular flat pillow. Although this pillow has a long history and looks practical and generous, it does not meet the physiological requirements of the human body. Long-term use will destroy the physiological curvature of the human cervical spine, resulting The neck muscles and ligaments are in a state of stress for a long time, so that the neck is not fully rested and strained.
There is usually such a feeling: when I wake up, I suddenly find that my neck is so stiff that I ca n’t move, and my back is sore and sore. Is n’t it obvious that I ’ve been sleeping all night? At this time, you need to carefully check whether your pillow conforms to the physiological curvature of the human neck.
The problem on the pillow: The cervical spine is located at the uppermost end of the human spine, wrapped in the neck, and consists of 7 vertebrae. The so-called physiological arc is a smooth, forward-facing arc formed by these 7 vertebrae. The function of the pillow is to maintain this normal physiological curve. How to maintain a normal physiological radian depends on whether you are really clear about the choice of pillow height and softness.
Height of pillow: This is also different from person to person. Although there is an old saying "sit up and relax", it is not that the higher the pillow the better. Because the pillow is too high, no matter what position you sleep in, it will affect your sleep. It cannot maintain the normal curvature of the cervical spine, but will move backwards.
Similarly, a pillow that is too low is not good, because a pillow that is too low can congest the head, which can easily cause puffiness of the eyelids and face, and the jaw will therefore lift upward, making it easy to open your mouth to breathe and snoring. Generally speaking, our sleeping postures are divided into supine, lateral and prone positions. It is best to choose a pillow that can maintain the normal physiological curvature of the neck regardless of whether you sleep on your back or side. Adults should have a pillow height of 15-20 cm when lying on their back, and a height of about 10-15 cm when sleeping on their side.
Pillow hardness: This is also suitable for moderate. Because the pillow is too strong, the area of contact with the head is reduced, the pressure is increased, and the scalp will feel uncomfortable; in turn, the pillow is too soft to maintain a certain height, which will cause excessive fatigue of the cervical muscles and affect the smoothness of breathing, which is not conducive to sleep . Only a little softer, without losing a certain hardness, can not only reduce the pressure between the pillow and the scalp, but also maintain uneven pressure, so that the blood circulation can pass through the place with less pressure and maintain a certain height.
Width of pillow: Under normal circumstances, it is better to be wider than the shoulder. Do n’t sleep too small pillow, because when you turn over, the pillow ca n’t support the neck. In addition, too small pillow will affect the sense of security during sleep.
