As soon as you open the door of your hotel room, it's hard not to notice the big white soft bed, but have you ever wondered why there are usually four pillows on the bed? The extra pillow, did you just put it away? In fact, this extra pillow is not prepared in thin air, there is a lot of knowledge.

I should think so! Of course, you go to the hotel to sleep, but don't think about it! Because the extra "they" are for your health.

The ancients say: "rest easy"; However, contemporary medicine believes that the pillow is too high or too low, it is not good for the cervical spine, the wrong position of the pad will cause problems, and it may be sore and uncomfortable in the short term, and it cannot escape major surgery for a long time.

Today, Tai Tang Xiaobian shares with you why hotel beds need 4 pillows:

It is very important to use the right pillow when you go to bed, and the pillow must be padded to the neck. Each person can self-test, when lying down, if the lowest part of the chin is in the air, it implies that the pillow is too low, if the chin is pressed down, that is, the pillow is too high, the degree of jaw should be maintained, is the comfortable and correct pillow height.

Sleep is a third of your life, and your posture is poor. Like some parents think that when their children sleep on a hard bed, their bones will grow right. There are many differences in the flesh of the buttocks, waist and shoulders of the human body, and the hard bed will make the curve of the body not stick to the bed surface, or even relax, not comfortable and not healthy. There are still many people who do not have pillows, and when they sleep, their heads will lean back, and the pressure on their cervical vertebrae will span twice as much as when they lean forward. As for the pillow bumpy, young people can be slightly lower, older to be slightly higher, because the flexibility of the cervical spine will change with the number of years, the older the more rigid, it is necessary to more support.

When sleeping flat (on the back), the pillow should be exactly from the entire head to the neck, not to the shoulders, not only to the back of the head half, it is best to place a small pillow under the knee; When sleeping on your side, double your height and tuck a small pillow between your knees. It is best to stop sleeping on your stomach, because the cervical vertebrae will suffer too much pressure; When you get up, remember to first side position, hand up, and then get out of bed, do not sit directly on your back and start straight. No matter how correct the posture is, it is not appropriate to be reliable for too long, it is necessary to change for a long time, to roll over when sleeping, to stand up and move for a long time, and the spine can be nurtures well.
