We must admit that even in today's highly developed science and technology, if we talk about health, we can't do without the wisdom of the ancients. Especially those summaries with Chinese medicine sources are still in use today. Withstanding the test of time, we are more convinced of the wisdom of the ancients in keeping in good health. Recently, a little friend mentioned a question related to the health of the ancients in the background: Why are the pillows of the ancients all made of ceramics or wood? Is it scary, or is a hard pillow really good for your health?

Why are ancient pillows mostly made of ceramics or wood?

Before solving this mystery, let's start with an equally old word:? People are not saints? . Yes, in fact, the ancients were also flesh and blood, and the pillows with ceramic pillows would be as flustered as we are. We have summarized several reasons for your reference:

First of all, hard pillows are really helpful for cervical vertebrae. Hard pillows can fit the physiological curvature of the body well, especially for people with cervical spine problems. But even so, we don't recommend that you really choose a hard pillow, because the pillow is too hard, but it will increase the pressure on the cervical spine because the contact surface becomes smaller, causing neck muscle fatigue.

Secondly, hard pillows are good for hair. As we all know, in ancient times, both men and women had the habit of keeping long hair, which faced two problems. The first is the problem of head cooling when sleeping, and the second is the problem of hair style. Let's start with the first one. Because the hard pillow is hard and high, it can help the head to dissipate heat. Here Li Qingzhao has poems as evidence. This festival is also the Double Ninth Festival, and Yu Zhen's screen is cool at midnight. ?

Let's talk about hair style again. Of course, it was not so convenient in ancient times. There are all kinds of shampoos, conditioners, hair dryers, etc. Was it troublesome for the ancients to wash their hair? Big deal? . For example, wrap the sludge in your hair with sawdust and fine sand, and then comb it repeatedly with a sieve. Or use natural plants that can remove oil stains (such as the fruits and leaves of Gleditsia sinensis), which is very troublesome in short. In order to save time in combing your hair and washing your hair in the morning, sleep on a hard pillow, throw your hair aside and try to keep your hairstyle.

Finally, other uses of hard pillows, such as students from poor families who participate in scientific research, use log pillows to prevent themselves from sleeping late. Police pillow? . Others hollowed out their pillows and hid some more valuable pictures, which is also commonly known as? The book in the pillow? . The book Take Care records Dan Shubo. As for the pillow, I think it is a treasure.

Of course, ancient people didn't always use hard pillows. After the Ming Dynasty, pillows made of ceramics and wood gradually declined, and some silk and cotton pillows became popular. As for why the pillows we see in museums are mostly hard materials such as ceramics or wood, it is also because pillows made of other materials are not easy to preserve.
