Height of pillow: The height of pillow should be appropriate, and the best height for lying flat is the height of one's palm. This height is the best height for a healthy person to be comfortable. This height refers to the height that a person can keep after lying down. Generally, most products sold in the market are divided into two types, one is silky, which instantly becomes lower when lying down, and the other is fixed height. When choosing a fixed height, be sure to pay attention to whether the deviation is too large.

Curve of pillow: Generally, the pillow is lower in the middle and slightly higher on both sides, which is more in line with the physiological curve of the neck. You must pay attention to the details when choosing a pillow. If the middle of the pillow is as high as the sides, it will be uncomfortable to lie down.

Material of pillow core: Because the function of pillow is to relieve the physiological curve of neck, the material of pillow core must have a certain hardness, and the pillow core with too soft material can't solve this problem. The traditional pillow core is generally made of buckwheat skin or other materials. Although it is hard enough, it will reduce the height of pillows, because they can't remain fixed during turning over. Therefore, it is recommended to choose a pillow with a fixed height.

Breathability of pillow: An airtight pillow will make your hair wet after a night's sleep, and the pillow will feel uncomfortable. This is also a very important detail in choosing a pillow. This mainly depends on the material of pillow core and pillowcase. Pure cotton pillowcase is the choice of most people.

Comfort of pillowcases: pure cotton pillowcases in winter and cold pillowcases in summer are the best choice for the season. Although there is air conditioning in summer, the combination of air conditioning and mat is a perfect match.

Choosing a good pillow is conducive to improving the quality of sleep: a pillow with a suitable height can effectively solve the fatigue during a night's sleep, especially when the neck is very uncomfortable.

Under the premise of no disease, I always turn over when I sleep at night, snore when I sleep, and I can't find the reason when I'm not tired, so I have to consider whether the pillow is not suitable or not. For people with poor cervical vertebrae, the requirements for pillows are even higher.
