There is an old saying in China called "Rest easy", but Rambo is here to tell you that it would be wrong for us to understand this saying from a professional perspective. The correct expression should be "comfortable pillow", so what is a good pillow?
In ancient times, there was a word to describe pillows: "If you lie on your side at shoulder height, you will feel comfortable." Rambo Sleep Research Institute tells you directly that the height of the pillow can keep the cervical spine neutral whether sleeping on your side or not. Practically speaking, when lying on your back, the pillow is about your fist, the top of your head is slightly tilted, and your neck feels supportive. This posture is the healthiest when sleeping.

Now, Rambo Sleep Research Institute will choose pillows for everyone. Opinion is to pay attention to the "three degrees":
1, height
A high pillow is not necessarily ok, and a flat pillow is not necessarily suitable. Generally, the height of the pillow is 10 cm ~ 15 cm, and the specific size depends on the physiological radian of each person. The general principle is that after sleeping, the pillow supports the curved part of the cervical spine, which is 3~5 cm higher than the part supporting the back of the head, and can support the head with the same height as the neck.

2. Difficulties
The pillow is moderate in hardness and hard, with small contact area with the head, increased pressure and uncomfortable scalp. On the contrary, the pillow is soft, it is difficult to maintain a certain height, the neck muscles are easy to fatigue, which is not conducive to sleep, and the head collapses, affecting blood circulation.
3. Width
Tossing and turning requires pillow width, which is generally wider than the shoulder, at least 1.5 times the shoulder width. Don't sleep with a narrow pillow, or your head will fall off when you turn the pillow, which will affect your sleep safety.
Now there are all kinds of pillow cores on the market, both high-end and ordinary. Today I will teach you what pillows to choose.
1. According to years of research, Rambo Sleep Research Institute found that goose down is the common filler in traditional pillows in high-end sleeping environment, and there are many people to choose from. It can well support the curvature of human cervical vertebra, is not easy to collapse, and can keep fresh and breathable, ensure smooth blood flow and relax tense muscles.
2. With the addition of breathable down, this pillow core has health care functions such as promoting sleep. However, it is very important that this kind of traditional pillow should be put in a ventilated place to dry regularly when it is maintained after use, so as to prevent bacteria and mites from breeding and not to be exposed to the sun.
