Temperature: After people fall asleep, the head temperature is generally 34-34.5 degrees Celsius, which is several degrees lower than the body temperature. If the head temperature is too high, it is not easy to fall asleep. Therefore, people choose cool pillows and warm pillows at different latitudes and seasons. In summer, most people often add a cushion to their pillows. Therefore, the choice of pillows should conform to the regional and seasonal characteristics, so that the head can keep the best sleeping temperature.

Height: Whether sleeping on your back or on your side, it is best to choose a pillow that can keep the normal physiological curvature of your neck. The height of the pillow is 15 cm when an adult lies on his back or side. 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 stiff neck. Over time, it will also cause morphological changes of the neck bones, such as physiological bending and straightening. Some people like to sleep without a pillow or the pillow is too low, which is not good. Will make the head congestion, easy to cause eyelid and facial edema, chin up high, easy to open your mouth to breathe and snore.

Hardness: A hard pillow will reduce the contact area with the head, increase the pressure, and make the scalp uncomfortable, while the pillow is too soft to maintain a certain height, which will lead to excessive fatigue of the neck muscles, affect the smooth breathing, and is not conducive to sleep. Only when the pillow is soft and does not lose a certain hardness can the pressure between the pillow and the scalp be reduced, the uneven pressure be maintained, and the blood can circulate through the place with less pressure. In addition, people's head shape is also related to the initial use of pillows. Neonatal pillows are moderate in hardness. Pay attention to adjusting the head angle from time to time to avoid bad shape when you grow up.

How to choose a pillow that suits you?

People spend13 of their life in sleep, and pillows can be said to be the longest companionship. Choosing an ergonomically designed pillow can not only ensure high-quality sleep, but also affect two-thirds of life's work, study and life quality.

Physicians say that all diseases originate from the spine. The function of the pillow is to ensure that the physiological curvature of the human neck does not deform during sleep.

Experts pointed out that the cervical vertebra is located at the top of the human spine, wrapped around the neck and composed of seven vertebrae. The so-called physiological radian is the smooth convex arc formed by these seven vertebrae.

Improper pillow selection directly affects sleep. According to the statistics of relevant departments, insomnia accounts for more than 35% of the total population in China. 60% of traffic accidents are caused by drivers sleeping less than 3.5 hours. The so-called "sit back and relax" argument is actually not scientific. The pillow is too high, no matter what position you sleep in, you can't keep the normal lordosis of the cervical vertebra, which will increase the burden of the cervical vertebra. If you have neurasthenia symptoms such as neck pain, headache, dizziness, tinnitus, insomnia, or feel numb after sleeping in the middle of the night, it may be that the pillow is too high; If the pillow is too low, the head will be congested, leading to edema of eyelids and face, chin lifting up, and it is easy to open your mouth and breathe and snore. Too low pillow, no pillow or too soft pillow can also cause neck and shoulder pain. Experts believe that whether sleeping on your back or on your side, it is best to choose a pillow that can keep the normal physiological curvature of your neck.
