Several key elements of buying a pillow
Many people buy pillows are rectangular flat pillows, this kind of pillow looks practical and generous, but long-term use will destroy the physiological curvature of the human cervical vertebrae, so that the neck can not get enough rest and strain. There are so many kinds of pillows on the market, how can consumers buy pillows from them?
The problem on the pillow: The cervical vertebra is located at the uppermost end of the human spine, wrapped in the neck, composed of 7 vertebrae. The so-called physiological curvature is a smooth, forward-facing arc formed by the seven vertebrae. The role of the pillow is to maintain this normal physiological curve. How to maintain a normal physiological curvature, it is necessary to see if you are really clear in the choice of the height and hardness of the pillow.
The height of the pillow: This is also different from person to person. Although there is a saying of "sit back and relax" in the old saying, it is not the higher the pillow, the better. Because the pillow is too high, no matter what position you sleep, it will affect your sleep. You can't maintain the normal lordosis of the cervical spine. Instead, it will go backwards, which will increase the burden on the cervical spine and may also cause a stiff neck. Similarly, the pillow is too low, because the pillow is too low, the head will be congested, and it will easily cause eyelids and facial swelling.
In general, our sleep posture is divided into three types: supine, side, and prone. Pillows are best chosen to maintain the normal physiological curvature of the neck, whether you are sleeping or sleeping sideways. Adults should have a height of 15 to 20 cm when lying on their back and a height of about 20 to 15 cm when sleeping on the side.
The hardness of the pillow: this is also appropriate. Because of the hard pillow, the contact area with the head is reduced, the pressure is increased, and the scalp will feel uncomfortable; in turn, the pillow is too soft and difficult to maintain a certain height, which will lead to excessive fatigue of the neck muscle and affect the smoothness of breathing, which is not conducive to sleep. . Only a little softer, without losing a certain hardness, can reduce the pressure between the pillow and the scalp, and maintain uneven pressure, so that blood circulation can pass from less pressure and maintain a certain height.
Pillow width: Under normal circumstances, it is better to be wider than the shoulder. Don't sleep too small a pillow, because when you turn over, the pillow can't support the neck, and the small pillow will affect the sense of safety during sleep.
The pillow core is a key factor in choosing a pillow. Here are a few common pillows, so you may wish to choose as needed.
Buckwheat pillows. The pillow core is made of buckwheat shell, which is a traditional folk pillow. The buckwheat husk is light in weight and has a tough and non-breakable rhombic structure. As a pillow core, it can change shape with the movement of the head, and it is warm in winter and cool in summer, and has the effect of clearing heat and bonfire. But the disadvantage is that it is not suitable for cleaning. It is best to dry in the sun regularly.
Ordinary man-made fiber pillows. Its advantage lies in easy cleaning, but due to the lack of elasticity and airtightness of chemical fiber materials, it will deform and agglomerate after a long time, making the pillows uneven, especially in some small manufacturers' inferior chemical fiber pillows.
Porous breathable fiber pillow. In the mall, we often see four-hole pillows, seven-hole pillows, nine-hole pillows, etc. of different brands. The filler inside is actually a chemical synthetic fiber commonly known as fluffy cotton. In the production process, the fiber center of the fluffy cotton will form a cavity, which is called a "hole". The process is different and the number of holes is different. In general, this pillow has high air permeability and good elasticity, which is very helpful for sleep.
Down pillows. The good down pillow has good bulkiness and will not be deformed due to the use of a long time. It has the advantages of light weight, breathability and no sultry heat. However, it is not easy to clean, and some people are allergic to down.
Natural latex pillow. It has the advantages of good elasticity, sterility, non-deformation, strong support, easy cleaning, etc., but the price is relatively expensive.
Natural cork pillows. Made of pure natural cork after dozens of special processes, the softwood particles have the characteristics of softness, good elasticity, light weight, good sweat absorption and high air permeability. Users can also change the shape of the pillow as needed, which is more beneficial to the cervical vertebrae. Health care.
Although many pillows look beautiful, they are not comfortable to use. Therefore, to choose a suitable pillow, in addition to "face", we must consider "lizi", hardness, height, size, so we must consider these "parameters" when choosing.
