Correct pillow method

In the use of pillows, the most important aspects are: the height, height, hardness and breathability of the pillow core.

Reasonable height

Generally speaking, people with high blood pressure, heart disease and asthma need to sleep on high pillows; People with low blood pressure and anemia need to sleep on low pillows. Too high or too low a pillow is not good for human health. So how high is the height of the pillow for normal people?

The general understanding is that it is more appropriate for people who are used to lying on their backs to have a punch on their pillows, and it is more appropriate for people who are used to sleeping on their sides to have a punch and a half on their pillows. However, according to a recent medical survey, healthy people change their posture about 20-45 times during 8 hours of sleep, and half of them change their posture in less than 5 minutes, of which 60% are supine, 35% are lateral and 5% are prone. Therefore, although people's pillow height often varies from person to person, it is related to everyone's height, fat and thin, shoulder width and narrow, head circumference and neck curvature. There is no certain standard, but the average person spends more time sleeping on his back, and the average doctor will suggest that the height of one punch is more appropriate, not the height of one punch and a half.

Reasonable hardness

Generally speaking, hard pillows are beneficial to human health, but hard pillows make the contact surface between the head and the pillow too small, and the local pressure is too large, which makes people feel uncomfortable, and it is likely to cause too much pressure on local nerves, leading to numbness or pain in the head, neck, back, arms and hands the next morning. Too soft a pillow is difficult to keep the height of the pillow, because too soft will oppress the scalp and is not conducive to blood circulation. At the same time, there is also the problem of poor air permeability, which can not ensure adequate breathing during sleep, and there may be potential safety hazards.

Therefore, the hardness of the pillow should be moderate, and the height of the pillow is different in different sleeping positions. It must be noted that when we lie on our back and side, the height of the pillow is about 15-20cm. For the health of cervical vertebrae, please choose pillows rationally.

Permeability and elasticity

The breathability and elasticity of pillows are mainly aimed at pillows with soft pillow core materials, because other filling materials, such as cassia seed, silkworm excrement, grain, elastic tubes, etc., can ensure good breathability of pillows and will not collapse without elasticity. However, soft materials such as vacuum cotton, cotton, sponge, etc. Generally, it may have poor air permeability and elasticity. According to medical investigation, prone posture occupies a certain proportion in everyone's sleep process. Pillows with poor air permeability will make people breathe poorly during sleep, which will seriously affect people's health and may even cause safety problems. At present, most pillow manufacturers in the market have considered this problem and adopted porous fiber to solve this problem.

Good elasticity mainly means that the soft pillow core material can prevent the pillow from collapsing, ensure the pillow to be used comfortably for a long time, and increase the supporting force of the neck bending, but the pillow with good elasticity also has the disadvantage of unstable sleeping position. The best pillow needs moderate elasticity and support.

Reasonable position

When sleeping, it is very important that the head is in a reasonable position on the pillow. Generally speaking, it is best to put your head in the middle of the pillow, so as to stabilize your sleeping position and avoid stiff neck caused by frequent posture changes at night. Second, it can make the neck have a certain supporting force and maintain the normal physiological curve of the body. The normal sleeping position is supine, with the head in the middle of the pillow and the neck on the edge of the pillow. The pillow will support your neck and will not put pressure on the cervical vertebra.

If the pillow core is made of inelastic material, you can flatten the middle of the pillow, raise the place where the neck rests on the pillow, so that the cervical vertebra does not bend forward or sideways, and maintain a proper backward extension position, so that the cervical vertebra will not be sore in the morning.

Extended data:

Change time

Simple introspection criteria for judging whether to change pillows;

1, in the absence of other physical diseases, I often feel numb and sour in my neck after getting up in the morning.

2. The pillow has lost its elasticity, and it takes a while to recover some elasticity.

3. After the pillow is finally adjusted, it will soon be flat.

4. Pillow caking is uneven, and the filler has a damp smell.

How long does it take to change the pillow?

Many people change their pillows only once every four years. In fact, pillows should be changed every 1 ~ 3 years.
