Unfortunately, all this progress has come at a price - namely, the degradation of the environment. In major cities around the world, including Seoul and other Korean cities, the air quality is almost intolerable. It is undeniable that this poor quality of air has taken its toll on our health. Because the nose tickles and people constantly sneeze when coryza arises, it is commonly thought that it is the nose that is in need of a cure. Therefore, in order to eliminate nose-related problems, the lungs should be thoroughly checked out as well.
Coryza develops as a result of cold air coming into contact with lungs weakened by polluted air.
Second, coryza strikes those who generally feel lethargic. They may look like they are in good shape from the outside, but the presence of coryza betrays poor health, and in turn, a poor immune system. For these people, improving the immune system should be the number one priority. Third, coryza also can arise when the spleen, stomach and kidneys fail to function properly. If the spleen stomach or kidneys are in bad shape, their temperatures rise, causing nasal inflammation.
