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 worst 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 pillows 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.
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. For sub-healthy or sick people, you can choose a medicine pillow, or add symptomatic drugs to buckwheat skin yourself. For example, patients with hypertension can choose chrysanthemum pillow and cassia seed pillow; Insomnia patients can choose lavender pillows or add sedatives; For patients with headache, drugs such as Ligusticum Chuanxiong, Radix Angelicae Dahuricae and Cortex Moutan can be added into the pillow core to dispel wind, relieve exterior syndrome, clear heat and cool blood, and promote blood circulation to remove blood stasis.
