People can relieve the fatigue of cervical muscles and ligaments during sleep in one day.
In traditional pillows, the head rests on the top of the pillow and the cervical vertebra is suspended, which makes the muscles and ligaments around the neck tense and blocks the passage of vertebral artery, which can only lead to stiff neck and dizziness and fatigue after waking up. According to ergonomics, the shape of the pillow is "high at the front and low at the back", which is most beneficial to cervical health. This kind of pillow can keep the physiological curvature of cervical vertebra by using the protruding part in front. Traditional pillow: ergonomic pillow with suspended deformation of cervical vertebra: cervical vertebra supports and conforms to natural flexion.
In recent years, with the development of ergonomics, health experts have designed various more ergonomic "cervical vertebra repair pillows", of which the following two designs have been recognized by consumers.
How to choose the height:
As the saying goes, rest easy, but it's not. The high pillow makes the cervical vertebra lean forward too much, and the soft tissue of the neck is too tense and tired, which is easy to cause stiff neck; At the same time, too high pillow will lead to insufficient blood supply to the brain, which is especially unfavorable for cervical spondylosis of vertebral artery type. On the other hand, some people prefer not to have a pillow or the pillow is too low, which is not good. The cervical spine is easy to hang, the chin will be lifted up, and it is easy to open your mouth and breathe and snore.
It is considered that the pillow height of Asian adults is about 8- 12 cm.
How to choose quality:
According to the principle of cold head and hot feet in traditional Chinese medicine, the material of pillow should be different according to the changes of seasons to keep the head fresh and breathable during sleep.
Summer: Suitable for pillows with buckwheat shells and popcorn shells as the main fillers. This pillow has good air permeability, strong plasticity and cool feeling. meanwhile
This substance has the effects of clearing away heat, calming the nerves and helping sleep. Judging from the current use area, there are more pillows made of rice husk in the north and more pillows made of buckwheat husk in the south.
There are more pillows, mainly because buckwheat hulls are more mildew-proof and insect-proof than rice hulls in hot and humid weather. Meanwhile, buckwheat husk is very hot in summer.
Loss of appetite has a good regulatory effect.
Winter: pillows mainly made of kapok and cattail are more suitable. This material has soft texture, moderate elasticity and good thermal insulation performance. At the same time, it belongs to pure natural material, which has physical therapy function. Kapok can clear away heat, remove dampness and detoxify, with excellent elasticity and the best supporting force. Pu Rong has the effect of calming the heart and stopping spasm, and it is very light and breathable. At the same time, these two materials are especially suitable for the humid characteristics of winter in the south, which are not easy to get wet and rarely moldy.
