The steps for choosing a special pillow for pregnant women are as follows

  1. The shape of the pillow:
    The problem on the pillow The cervical spine is located at the uppermost part of the human spine, wrapped in the neck and composed 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 curvature depends on whether you are really clear about the choice of pillow height and softness.
    How to choose:
    The height and softness of the pillow are the key. According to analysis, when a person lies on his back, the cervical spine is most suitable for bending about 3 cm. Pillows that are too high or too low, too soft or too hard, will affect both the quality of sleep and health. It also causes and aggravates the hidden dangers of cervical spondylosis. A good pillow should be able to support the head and neck at the best angle, moderate in hardness, and quickly return to its original shape after being compressed, and it is not easy to deform after long-term use.
    In traditional pillows, the head is placed on the highest part of the pillow, and the cervical spine is suspended, which makes the neck muscles and ligament joint bundles in a tense state, and the passage of the vertebral artery is blocked. Only after waking up, the neck becomes stiff and dizzy. According to ergonomics, the shape of the pillow with a “high front and low back” shape is most conducive to cervical spine health. This pillow can use the front protruding part to maintain the physiological curvature of the cervical spine. Pillow replacement self-examination criteria: In the absence of other physical diseases, I often feel numbness in my neck after getting up in the morning. This is the shape of the pillow is wrong
  2. The height of the pillow:
    The height of the pillow also varies from person to person. Although there is an old saying that “sit back and relax”, it is not that the higher the pillow, the better. Because the pillow is too high, no matter what posture you sleep in, it will affect your sleep. It will not maintain the normal curvature of the cervical spine, but will go backwards, which will increase the burden of the cervical spine and may also cause stiff neck. Similarly, a pillow that is too low is not good, because a pillow that is too low will congest the head and easily cause swelling of the eyelids and face.
    How to choose high:
    As the saying goes, sitting back and worry-free, in fact, high pillows make the cervical spine too forward, and the soft tissues of the neck are over-tightened and fatigued, which may cause stiff neck. At the same time, too high pillows can cause insufficient blood supply to the brain, which is particularly detrimental to vertebral artery cervical spondylosis. On the contrary, some people like to sleep without a pillow or the pillow is too low. This is not good. The cervical spine is easily suspended, and the lower jaw will be lifted up. It is easy to breathe and snore.
