Let's start with what a cave is. Cave dwelling is an ancient way of life for the residents of the Loess Plateau in northwest China. Cave style? The history of folk houses can be traced back to more than four thousand years ago. Cave dwellings are widely distributed in Shanxi, Shaanxi, Henan, Hebei, Inner Mongolia, Gansu, Ningxia and other provinces on the Loess Plateau. In the Shaanxi-Gansu-Ningxia region of China, the loess layer is very thick, some of which are tens of kilometers thick. The people of China creatively used the favorable terrain of the plateau to dig holes to live, and created cave buildings called green buildings. Cave dwellings generally include cliff cave dwellings, sunken cave dwellings, independent cave dwellings, etc., among which backer kiln is widely used. In the past, a farmer worked hard all his life, and his basic wish was to build several caves. Marrying a wife in a kiln is a family business. Men dig in the yellow soil, and women do housework and have children in caves. Cave dwelling is a product of the Loess Plateau and a symbol of the people in northern Shaanxi, which has precipitated an ancient and profound yellow land culture.
In fact, what are the benefits of living in caves to our health?
The temperature in the cave changes little in winter and summer. Because of its good thermal insulation performance, it is warm in winter and cool in summer. The cave was dug on the hillside, so its "roof" and "wall" are quite thick. When people dig caves, they choose places with hard soil. This thick and hard "wall" is not easy to transfer heat. Therefore, the top and wall of the cave can neither directly absorb heat from the atmosphere nor directly dissipate heat to the atmosphere, only the hole is in direct contact with the outside world. Therefore, the temperature change in the cave always lags behind the external temperature change, and the temperature difference changes little.
So the temperature in the cave is warm in winter and cool in summer, which is good for the body, so it will be healthier and have a longer life.
