First of all, Xi's residential culture originated in the pre-Qin period, which is almost equivalent to the present desk and chair lifestyle. There is a hard floor below, so it must be uncomfortable to sleep. However, this culture has a history of more than 7,000 years in China. According to the available data, it was probably from the Western Zhou Dynasty to the Han Dynasty. In the following thousands of years, although we had more comfortable soft beds and beds in China, this culture influenced it.
Second, ancient pillows According to expert archaeology, people began to use pillows in the Neolithic Age of about 65,438+/kloc-0.0 million years. The earliest use was only to raise people's heads to sleep, mainly to prevent bugs from crawling into their ears, mouths and noses. At that time, most of them were hard objects such as sticks and stones, and later they became soft pillows. However, most of us will find out why ancient people used such hard porcelain pillows when watching costume dramas.
Li Shizhen mentioned the explanation in Compendium of Materia Medica. ? Long-term use of porcelain pillows can clear the heart and improve eyesight, and even fight against various shoulder and neck diseases? . Third, the life expectancy of ancient people is generally not high, but even though ancient people paid more attention to sleep and health preservation, they did not live as long as modern people. This still stems from some external factors in ancient times. In the farming society, almost all people depend on the weather for food, but in case of a little accident and no other preventive measures, there is a lot of drought every year, and it is a problem to eat enough and wear warm clothes. Coupled with occasional wars, some diseases can not be treated in time, and the life expectancy of ordinary people is generally not high.
