One third of one's life is spent in bed. So from ancient times to today, people pay attention to the quality of sleep, for the pillows used in sleep also carry out a variety of research, there are pillows of different shapes and materials. The quality and shape of pillows are directly related to the quality of sleep at night. The direct contact with the pillow is the cervical spine of the human body, and the cervical spine is closely related to the shoulder, back and waist muscles, ligaments, intervertebral discs and so on. It can be seen that the appropriate pillow has an impact on human health.

So how to choose a comfortable pillow?

Hardness and elasticity in the choice of pillow softness and hardness, too hard pillow makes the head and pillow contact area small, local pressure, sleep very uncomfortable. Pillow is too soft, the head will sink in, affecting blood circulation, numbness the head, but also easy to cause neck muscle fatigue, pillow elasticity can not be too large, otherwise the neck is very tired, easy to cause neck muscle damage. Therefore, consumers should choose pillows with moderate hardness, resilience and good support when purchasing.

The height of the pillow is related to the quality of sleep and the Department of physical health. If the pillow is too high, the cervical spine will be slowly deformed, the muscles of the neck will be strained, and bone spurs may be formed. When pillow high pillow, breathing will not be smooth, prone to dry mouth, sore throat, snoring and other conditions, wake up will feel neck pain, headache, dizziness, tinnitus. Pillow low is also not good, also unfavorable to the cervical spine, easy to open mouth breathing, snoring, wake up will appear head swelling, irritability, facial edema.

The appropriate height of the pillow is generally 10 - 15 centimeters, shoulder width, body fat, long neck of the person's pillow should be slightly higher. The height of pillow should be the same as the height of one's own fist (the height of clenching tiger's mouth upward) after compression, while the height of pillow should be the same as the width of one's shoulder after compression for those who are used to sleeping on one side.

When the pillow filler sleeps, it almost touches people at the nearest distance, so the quality of the pillow filler has a great impact on our health. There are many kinds of pillow fillers. Only by clearly understanding the advantages and disadvantages of different fillers, can we choose the most suitable pillow type according to the individual situation.

Flexible feathers. Down fibers have good resilience, temperature and humidity adjusting functions, high permeability, and can provide a "small environment" for the human body to dry and comfortable. But the down pillow can not be washed, it is easy to breed bacteria and mites, allergic people had better avoid using this pillow, in order to avoid causing respiratory discomfort.

Common man-made fibers for easy cleaning. The filler is made of chemical fibers and cotton floss, which is easy to wash, and can even be washed by washing machine. It can also be compressed and collected by vacuum compression bag, and the price is cheap. However, chemical fibers and cotton floss are not very breathable and easy to cake and pellet over a long period of time, thus lacking elasticity and shortening the life of cotton floss.

Natural environmental friendly natural fillers, such as natural latex, buckwheat husk, rice husk and so on. Compared with man-made chemical fibers, modern people prefer to use pillows filled with healthy and environmentally friendly natural materials. Buckwheat skin with moderate hardness and softness is the most common pillow filler. It is moderate in hardness and softness, good in moulding and water absorption, and relatively light. The disadvantage is that the elasticity is poor and the pillow sounds when the head and neck move. For insomniacs, it may affect falling asleep. And long-term application will cake the pillow, leading to cervical spondylosis.

The pillow core made of natural latex not only combines the advantages of the above fillers, but also improves their disadvantages. Because natural latex comes from natural materials, it is non-toxic and tasteless, and has no adverse effects on human body. The integral structure of latex eliminates the interference of fine fibers to human body, and is especially suitable for allergic constitution and asthmatic patients. In addition, natural latex has good air permeability, supportability, durability, is not easy to deform and easy to shape, and can provide more appropriate support for cervical spine, thereby alleviating the pain and discomfort of neck and shoulder.
