Atmospheric pollution is one of the main environmental pollution factors in China, along with the rapid development of industrialization and urbanization, the environmental quality of many cities in China, especially the quality of the air environment has deteriorated to varying degrees, “haze” heavy pollution days continue to increase. Because of its close relationship with health, this year has become one of the hot issues of concern to the general public. Atmospheric particulate matter (PM), nitrogen dioxide (NO2), sulfur dioxide (SO2) are the main pollutants of the current urban air quality, of which the concentration of fine particulate matter (PM2.5) with an aerodynamic diameter less than or equal to 2.5um is closely related to respiratory diseases, cardiovascular diseases and immune function damage, as the saying goes, “people As the saying goes, “People are like fish in water when they are in the air. If the water is turbid, the fish will be thin; if the air is faint, people will be sick”. Serious air pollution events occur frequently, and the scope of impact is getting bigger and bigger, which brings great harm to the people’s health, social progress and economic development and poses a serious threat. ”The lungs are the main gas, the division of breathing”, in a serious air pollution environment, atmospheric pollutants in the PM2.5, NO2, SO2 and other “poisonous evil” can enter through the mouth and nose with breathing; “the lungs outside together with the skin and hair “, “poisonous evil” invasion from its combination, can be from the skin and hair of the Xuanfu and enter; “(five organs and six bowels of the cough) this are gathered in the stomach, about the lungs”, and “the lungs and large intestine in the surface “, “poisonous evil” can also enter through the mouth from the intestines and stomach through diet. These poisonous evils come from the outside, through breathing, skin and hair, diet and other ways, invade the body from the outside and inside, take the qi and blood as the carrier, and do nothing to block the qi, defeat the blood, damage the lungs, and produce different pathological damage. Respiratory diseases caused by atmospheric pollution include acute bronchial, asthma, chronic obstructive pulmonary disease (chronic obstructive pulmonary disease), chronic bronchitis (chronic bronchitis), lung cancer, etc., which are related to atmospheric pollutants and other “poisonous evil” causing disease: “poisonous evil” causing disease is easy to corrupt the body. Atmospheric pollutants have serious inflammatory damage and oxidative damage to the respiratory tract and lung tissue, which can cause organic lesions in the respiratory tract and lung tissue; “toxic evil” invades the human body, leading to the internal growth of toxic evil, stagnation of toxic evil, which damages the vital energy over time, and if the vital energy is insufficient, it is unable to resist the evil, which makes the organism constantly feel the “toxic evil”. Toxic evil”, recurrent attacks are difficult to cure. During atmospheric pollution, patients may suffer from upper respiratory tract infections, acute tracheobronchitis, acute attacks of asthma, chronic obstructive pulmonary disease and chronic bronchial disease, resulting in coughing, breathing difficulties, nasal congestion and runny nose, eye and throat irritation, rash and other symptoms. Therefore, in hazy weather, doors and windows should be closed, indoor activities should be carried out as much as possible, and if you have to go out, it is best to bring N95 masks; clean your mouth, nose, face, hands and body when you return from going out; patients with a history of eczema should moisturize their skin several times a day; reduce the use of contact lenses; drink more water to help the kidneys excrete toxins absorbed through the skin and lung tissue; increase the intake of foods rich in vitamin C, vitamin E, OMEGA- 3 fatty acids, etc. If the haze causes significant physical discomfort, immediate medical attention is required. Chinese medicine “treats from toxins”, applying “detoxification method”, “detoxification method” and “anti-toxic method”, etc., for It provides a new theory and way to prevent and treat respiratory diseases caused by air pollution.
