I. What is haze Haze, also known as haze, haze, is a cloudy phenomenon formed by a large number of particles such as smoke and dust suspended for unknown reasons. The core material of haze is the dust particles suspended in the air, known as aerosol particles in meteorology. In recent years, the frequency of the “haze” weather phenomenon has increased, leading to a gradual deterioration in air quality. Haze contains hundreds of atmospheric chemical particles that invade the human respiratory tract and lungs when people are unprepared, causing respiratory diseases, cardiovascular diseases, hematological diseases, such as pharyngitis, emphysema, asthma, rhinitis, bronchitis and other inflammatory diseases, as well as lung cancer, myocardial ischemia and damage when exposed to this environment for a long time. As a pathogenic evil, haze is a product of the industrial age, and traditional Chinese medical theory is all-encompassing and common to both ancient and modern times. What are the pathogenic characteristics and preventive measures? Second, the fog is wet and turbid, haze is dry and turbid turbidity, refers to all blockage of the clear orifice of the evil, fog and haze belong to the category of turbidity. However, fog is a damp and turbid gas, Yin, is a heavenly phenomenon, since ancient times; haze is a dry and turbid evil gas, Yang, more man-made, recent appearances. There are several reasons: 1. From the climatic conditions under which they are formed, the air is humid when fog appears; when haze appears, the air is relatively dry, and the relative humidity of the air is usually below 60%. Therefore, fog is wet and haze is dry. 2. From the manifestation of disease caused by both, feeling the evil of fog and dew will make people dizzy, chest tightness and nausea, and even diarrhea, a manifestation of disease caused by wet evil; feeling the evil of haze will cause dryness of mouth, nose and eyes, sore throat, dry throat, dry cough, little and sticky phlegm, etc., a manifestation of disease caused by dry evil. Therefore, we say that the essence of this haze evil created by modern humans should belong to the dryness evil among the six evil spirits. Some people may ask, “What are the properties of the evil qi when fog and haze are present together? In fact, the fog is a product of nature, less harmful to the human body, the most important is the haze to the human body, and now although the haze collectively, more haze. Therefore, haze causes disease, dry evil characteristics are more obvious. Third, the characteristics of the haze evil cause disease 1, haze evil is Yang, easy to hurt Yin. Yang evil tends to harm the body’s yin, leading to yin deficiency symptoms. For example, harming lung yin leads to dry cough without phlegm or little and sticky phlegm, dry nasal cavity and dry skin, harming stomach yin leads to dry mouth and throat and thirst, harming liver yin leads to dry eyes, etc. 2.Haze is a dry evil, easy to hurt the lungs. We know that “the lung is a delicate organ, like moistening but not dry”, dryness is most likely to hurt the lung, in addition to the symptoms belonging to the above article, long-term stimulation will appear impotence, canker sores or slow obstruction of the lung, forming a more serious disease. 3, haze is turbidity, easy to block the clear orifices. Turbidity is easy to block the clear orifices, resulting in dry eyes and blurred vision, dizziness and dizziness, and easy to obstruct the rise and fall of the clear qi in the body, resulting in nausea, chest tightness and other symptoms. Fourth, the haze of Chinese medicine prevention rules In addition to the traditional wear a mask, reduce outdoor activities, combined with Chinese medicine on the understanding of the haze caused by disease, in terms of dietary therapy meals, the following are recommended for use. 1, the method of nourishing Yin and preventing dryness – saxifrage and lily porridge, for the main evidence of dry mouth and throat, dry skin-based people.
