Why are there four pillows in the hotel?

When we usually stay in a hotel, we will find that the hotel has four pillows, and most people will not pay attention to the extra pillows. In fact, these four pillows are very useful and can be used to adjust sleeping posture. The standard supine sleeping position should be to keep the chin level, which is the most comfortable time and can be adjusted with a pillow.

In addition, for our health, if the pillow exceeds our shoulders, it will make our shoulders and cervical vertebrae uncomfortable. At this time, we can put a pillow under the cervical vertebra, so that the cervical vertebra will not fail and it will be more comfortable to sleep. Another pillow can be placed under the knee, so that our legs can be slightly bent and relaxed.

When lying on your side, if you feel your neck dangling, you can put a pillow under it. You can also put a pillow between your legs at this time. This sleeping position will be more comfortable. Let's give you some knowledge about popular science. When we sleep, we should try to avoid sleeping on our stomach, because sleeping on our stomach is not good for the cervical spine and the heart, and we will feel very tired after waking up after a night's sleep.
