If you want a good sleep, you must have a good pillow.
The height of the pillow has great influence on the quality of sleep.
As the old saying goes, "Sit back and relax". Is it true?/You don't say.
The answer is no, too high a pillow is the most unfavorable for cervical vertebrae.
Under normal circumstances, the entire spine of the human body maintains a certain physiological curvature. If the pillow is too high to bend, then the cervical vertebra, thoracic vertebra and lumbar vertebra are not on the same plane. After a long time, cervical spondylosis will occur.
Similarly, the pillow should not be too low, otherwise it will cause dizziness, eyelid edema and so on.
There is a saying in Lao Lao Heng Yan: "If you are high or low, you will feel comfortable lying on your side just at shoulder height, that is, lying on your back."
Tell us a standard principle of measuring pillow height, that is, when lying on your side, your head is flush with your shoulders, so as to ensure that the whole spine is on the same level and will not cause scoliosis.
The comfort and hardness of a pillow with moderate hardness have a great relationship.
Too soft pillows increase the contact area between the head and the pillow, which makes the blood flow in the brain blocked by oppression, thus reducing the quality of sleep and easily waking up when sleeping.
A pillow that is too hard will make the head feel uncomfortable because the contact area between the head and the pillow is too small. When you sleep, you will consciously contract the muscles of your neck, which will make your muscles tense and you can't get a good rest. If you catch a cold carelessly, it will easily lead to stiff neck.
In addition, the pillow should have a certain length, not too short, and it must be ensured that the head will not fall off when the two sides turn over.
There is a related discussion in The Old Man's Constant Speech Pillow: "The old man needs a long pillow when he sleeps alone, so he won't stay in one place opposite."
It can be seen that the pillows used by the elderly should be longer.
Pillow filler Pillow filler is very important because it is related to the health of the brain.
Pillow fillers commonly used by modern people include buckwheat husk, rice husk, memory cotton, latex, down, man-made fiber and so on.
What kind of pillow is good?
It varies from person to person.
A comfortable pillow must ensure that the head is closely combined with the pillow when people lie down, which is just suitable for the physiological bending of the cervical spine and helps them sleep.
Buckwheat skin pillow is the first choice for most people, because it can make a head shape at will and play a certain supporting role.
Memory cotton pillows, which are popular in the market in recent years, are also favored by some people, especially office workers with poor cervical vertebrae.
Memory cotton has viscoelasticity, which can fix the head well, prevent the head from sliding and reduce the possibility of stiff neck.
In the era of great health, people pay more attention to preventive health care products, and there is a market for medicinal pillows, such as lavender pillows, chrysanthemum pillows and cassia pillows. In fact, ancient health care practitioners and Taoist priests have long had the tradition of sleeping on medicine pillows.
There are many meridians and acupoints in the head. Adding medicine into pillow stuffing will make use of the temperature of the head during sleep to emit the effective components of the medicine, which will penetrate into the whole body through the meridians and acupoints of the head, thus achieving certain preventive, health-care and even therapeutic effects.
Ge Hong of Jin Dynasty recorded the function of cassia seed pillow in his book "Elbow Emergency Prescription": "Cassia seed is better than black beans as a pillow. Treat the wind and improve your eyesight. "
In Ming Dynasty, Li Shizhen recorded the dietotherapy function of mung bean pillow in Compendium of Materia Medica. "Mung beans are sweet, cold and non-toxic, and can be used as pillows to improve eyesight and treat head wind and headache."
Generally speaking, people without diseases can choose pillow fillers at will, and they can choose according to their own preferences without affecting sleep and cervical vertebrae.
