Why do hotel rooms have more pillows?

As soon as you open the door of a hotel room, it's hard not to notice the soft white big bed, but have you ever wondered why there are usually four pillows on the bed? Did you just put this extra pillow aside? In fact, this extra pillow is not prepared out of thin air, but has certain health considerations and is very knowledgeable.

1, when lying on your back, if your shoulders exceed the pillow, it will easily cause pressure on the cervical spine; If only half of the head is attached to the pillow, the cervical vertebra will be suspended, which is also an inappropriate sleeping position. At this time, you can put a pillow under your head and neck to make a real pillow. The pillow should be just padded to the whole head to the neck, not to the shoulders, and not only to the half of the back of the head. The other pillow is placed under the knee, which can make the knee joint in a state of mild flexion and relaxation.

If you lie on your side, the width of your shoulders will cause your head and neck to droop. If the pillow is low, you can stack two pillows together and put a small pillow between your knees, which will make you feel very comfortable. In addition, the doctor suggested that it is best to avoid sleeping, because the cervical vertebra will bear too much pressure; Remember to stand on your side when you get up, raise your hands, and then get out of bed. Don't just sit up straight on your back.
