Why did Yang Guo and Little Dragon Girl live in seclusion in the cave after the third Huashan sword talk?

Friends who have seen The Condor Heroes know that after the Third Huashan Sword War, Little Dragon Girl and Yang Guo lived in seclusion in the killing game of Zhong Nanshan Mountain and never left their graves. The so-called ancient tomb is actually a cave villa converted from a cave. In fact, it is difficult for the little dragon girl to go back to the tomb with Yang Guo to live in seclusion. In fact, she is a patient with respiratory diseases. I have been in the ancient tomb in my early years, so I am not completely ill.

Since being taken out of the tomb by Yang Guo, she often vomited blood, coughed and looked pale. After the war in Xiangyang, the little dragon girl's breathing problem became more serious. After the third Huashan dispute, she can no longer walk the rivers and lakes. In fact, Yang Guo had to take her back to the grave cave to live in seclusion and heal her. Why can caves rest? In ancient times, no one gave a scientific view. People think that caves are very powerful, because monks, Taoists and other practitioners will choose the ancient Xianshan caves, which are called "Neanderthals".

With the development of modern science and technology, people have discovered the secrets in caves. There is a scientific basis for the little dragon girl to choose a cave for recuperation. Let's start with cave medicine.

The so-called cave medicine refers to a medical method that uses the special properties of caves to make patients gradually recover after entering caves. It is mainly used for treating respiratory diseases such as bronchitis and chronic bronchial asthma. Cave medicine is a new research field, which permeates many disciplines such as geology, environmental science, chemistry, medicine and tourism.

Early caves were mainly used for life and sacrifice, and there have been long-term records of cave medicine abroad. Later, it was found that asthma patients who stayed in caves for a long time would have symptoms such as dyspnea, cough, and reduced phlegm, and patients would also take less medicine, so the physical rehabilitation effect was obvious.

During World War II, the inhabitants of Tutu, antipas, Germany always regarded this natural cave as a refuge. Dr. Carl Herman was surprised to find that the health status of asthma patients who stayed in caves for a long time has been greatly improved. After the war, the influence of caves on asthma, chronic bronchitis and whooping cough was studied, and the medical effect of caves on some respiratory diseases was published in 1949. Some eastern European countries also began to establish cave medical centers after World War II to explore the use of caves to treat certain diseases. Now more and more European countries use caves (mainly caves) to carry out medical activities. This underground cave therapy is often called "cave therapy" abroad. Through the study of the disease phenomenon, it is found that saturated salt particles in the air are the main therapeutic factors. Later, some countries in Eastern Europe also developed local artificial salt caves. Due to the harsh external natural conditions, the microclimate in the cave is difficult to control. It was not until 1982 that people successfully built a salt therapy room and used the air conditioning technology of space flight to control the microclimate. The salt therapy room is not limited by time and space. It can provide medical, rehabilitation and leisure services for patients in special buildings. This method of treating diseases in artificial salt spots or salt therapy rooms is generally called "salt therapy" abroad and "aerosol salt therapy" at home.
