First of all, we should know that there were no cooling tools in ancient times. Unlike our current cooling tools, they use air conditioners and eat popsicles, so they want to sleep more comfortably in hot summer, so they can only do something on their pillows, so they use porcelain pillows as their own pillows to cool down.

Secondly, the ancient people's research on Chinese medicine can be said to have risen to a very advanced level. For example, many previously circulated remedies have been lost, but we can still find fragments from some historical materials. For example, some data show that sleeping with this porcelain pillow for a long time is conducive to promoting blood circulation and even treating your cervical spondylosis, so this porcelain pillow was very popular at that time.

But then again, not everyone can use this kind of pillow. It can be said that those who can use porcelain pillows are either dignitaries or relatives, and ordinary people do not have this opportunity.

In addition, porcelain pillows look beautiful on the surface, and ancient people also have a high pursuit of beauty. For example, they like to pursue some flashy things, which is a big reason why many emperors like exquisite palaces. So can they be unhappy with such beautiful things on their heads?

Not only that, in ancient times, most men and women had long hair, but there was no convenient way to take care of it. If you sleep with pillows made of other materials, you will find that your whole hair will be in a mess overnight, but porcelain pillows are different.
