Why are there four pillows in the hotel room?

Why put four pillows in the hotel room? To this end, I also called my sister for advice. After all, the internship place is in a five-star hotel ~

First of all, I personally like to sleep with soft beds and hard pillows, or I will feel very comfortable if you give us pillows to sleep with. But the hotel is very particular about putting four pillows ~

Sleep accounts for one third of life, so you can't ignore your posture. Medicine believes that the pillow is too high or too low when sleeping, which will affect the physiological curvature of cervical spine and chest. Too high a pillow can easily lead to respiratory diseases, such as snoring (although I haven't snored here yet just because I am too fat and the parallel position is higher than one of my pillows, so I will choose a hard pillow or two pillows superimposed); Too low a pillow can easily make the brain in a state of congestion during sleep, leading to dizziness and other discomfort the next day. Stiff neck is mostly caused by improper use of sleeping pillow, improper sleeping posture or catching cold.

Have any friends staying in the hotel found that the bed is particularly soft and short, and people will not be uncomfortable sleeping in parallel.

So many people sleep with one pillow and the other pillow under their knees, which can reduce stress.

There is a saying in folk proverbs that "live three inches long and have no worries about four inches", which means that if you want to live a long life, you should always rest on a pillow three inches (about 9 cm) high; If you want to sleep comfortably, you often use a pillow four inches (about 12 cm) high.
