What kind of pillow height is suitable for people to spend their lives in sleep 1/3, pillows can be said to be our longest partners. The right partner can not only ensure our high-quality sleep, but also determine the quality of work and life for the remaining 2/3 hours. If you wake up and find that your neck can't move, and your back is sore and tired, you should consider whether the pillow is working. Choosing a pillow that conforms to human mechanics design is not only beneficial to the cervical spine, but also beneficial to the physiological bending of the whole spine and paravertebral muscles. The source of all diseases starts from the spine, and the spine can remain healthy forever. The function of the pillow is to ensure that the physiological curvature of the human neck does not deform during sleep. According to experts, the cervical vertebra is located at the top of the human spine, wrapped around the neck and composed of seven vertebrae. The so-called physiological radian is the smooth and forward arc formed by these seven vertebrae, and 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 height, hardness and size of the pillow. Improper pillow selection directly affects people's sleep. So what kind of pillow is suitable? The old saying "sit back and relax" is actually not scientific. The pillow is too high, no matter what position you sleep in, you can't keep the normal lordosis of the cervical vertebra, which will increase the burden of the cervical vertebra and may also lead to stiff neck. If you have neurasthenia symptoms such as neck pain, headache, dizziness, tinnitus and insomnia, or feel numb during sleep, it may be that the pillow is too high; If the pillow is too low, the head will be congested, which will easily lead to eyelid and facial edema, chin lift up, easy to open your mouth and breathe, leading to snoring. If the neck and shoulders are sore after waking up, it is because the pillow is too low, the pillow is not used or the pillow is too soft. Experts pointed out that whether sleeping on your back or on your side, it is best to choose a pillow that can keep the normal physiological curvature of your neck. The height of the pillow for adults is 15 ~ 20cm when lying on their back, and about 20 ~ 15cm when sleeping on their side. Because everyone's cervical vertebrae are different, it may be our best choice to tailor different healthy pillows. It takes some time to choose the right pillow, and having a good pillow adds a comfortable condition.
