How to buy a pillow is the most beneficial to health
Usually there is such a feeling: When I wake up, I suddenly find that my neck is stiff and unable to move. The whole body is sore and sore, is it not a sleepy night? How can I sleep more and more tired? If you have had similar experience. Then, you need to carefully check to see if your pillow fits the physiological curvature of the human neck.
Problem on the pillow
The cervical vertebra is located at the uppermost end of the human spine and is wrapped in the neck and consists of 7 vertebrae. The so-called physiological curvature is a smooth, forward-facing arc formed by the seven vertebrae. The role of the pillow is to maintain this normal physiological curve. How to maintain a normal physiological curvature, it is necessary to see if you are really clear in the choice of the height and hardness of the pillow.
Pillow height
This is also different from person to person. Although there is a saying of "sit back and relax" in the old saying, it is not the higher the pillow, the better. Because the pillow is too high, no matter what position you sleep, it will affect your sleep. You can't maintain the normal lordosis of the cervical spine. Instead, it will go backwards, which will increase the burden on the cervical spine and may also cause a stiff neck. Similarly, the pillow is too low, because the pillow is too low, the head will be congested, it will easily cause eyelids and facial swelling, and the lower jaw will lift upwards, it is easy to breathe and snoring. In general, our sleep posture is divided into three types: supine, side, and prone. Pillows are best chosen to maintain the normal physiological curvature of the neck, whether you are sleeping or sleeping sideways. Adults should have a height of 15 to 20 cm when lying on their back and a height of about 20 to 15 cm when sleeping on the side.
Pillow hardness
This is also appropriate to moderate. Because of the hard pillow, the contact area with the head is reduced, the pressure is increased, and the scalp will feel uncomfortable; in turn, the pillow is too soft and difficult to maintain a certain height, which will lead to excessive fatigue of the neck muscle and affect the smoothness of breathing, which is not conducive to sleep. . Only a little softer, without losing a certain hardness, can reduce the pressure between the pillow and the scalp, and maintain uneven pressure, so that blood circulation can pass from less pressure and maintain a certain height.
Pillow width: Under normal circumstances, it is better to be wider than the shoulder. Don't sleep too small a pillow, because when you turn over, the pillow can't support the neck, and the small pillow will affect the sense of safety during sleep.
