The so-called "environmental pollution" refers to the existence of substances harmful to human body in the surrounding environment. Some harmful substances can be seen with the naked eye, but most of them are invisible. Therefore, "pollution" does not mean "dirty". A clean place There may also be pollutants. Most of the harmful substances that pollute the environment come from chemical by-products of industrial production, chemical fertilizers, pesticides and herbicides of agricultural production, gaseous products of fuel, domestic waste, scientific research and medical sites Waste, etc.
Environmental pollution is closely related to asthma. There are many harmful irritants that can induce asthma in the living environment. Most of them act on people's respiratory tract in gaseous form, and the most common ones are gas and oil Smoke, passive smoking, insecticide sprays, mosquito smoke incense, etc. In addition, the broad sense of environmental pollution should also include occupational exposure and some physical factors. However, some asthmatics may not be harmful to the general population, but their "antigenicity" or Irritation can cause disease in patients with asthma.
1. Gas, oil fume, etc
Gas and lampblack are common inducements for asthma attack of housewives, especially in winter when coal burners (honeycomb briquette Sulfur dioxide can be produced when coal balls or coal pieces are burned), gas stoves, but the oil smoke stimulation during cooking and frying, especially when frying food with high volatility such as pepper, is also easy to induce asthma attacks. Those induced by irritating smoke, many For patients living in the downwind. If there are smokers in the family, the smoke emitted by them is
Psychologists believe that asthma patients have strong dependence, more passive, cowardly and sensitive, emotional instability and self-centered personality characteristics. In clinical practice, we often see some stubborn and irritable patients who are not easy to accept the doctor's advice and prevention guidance. These patients often take large amounts of medicine, but the curative effect is poor. However, if these patients taste the benefits of certain drugs or therapies, it is extremely difficult for doctors to change their minds and accept new treatments. If there is a patient who has asked for antibiotics for a long time, in fact, his condition is very stable, and there is no sign of infection. How to explain it is no good. Ask him why? He said that once his asthma attack was very serious, and it was only good to use Fudaxin (Ceftazidime) for infusion (in fact, he also used glucocorticoid). This shows that antibiotics have formed a strong exciting focus in his brain, and he believes that the specific drug for his disease is antibiotics. Psychologists also found that mothers of asthmatic children often have a "neurotic" personality, and their anxiety, nervousness, nagging and annoyance affect children.

(1) Bronchial tree structure and lung function: the basic lung function of infants has an important impact on the severity of asthma attacks. The early airway conductivity of infants is low, so the chance of suffering from wheezing disease within 1 year old is 3 to 6 times higher than that of normal children, and this risk factor can last until 3 years old. Preschool children are prone to viral respiratory infection. One of the important factors is that small airways are relatively narrow, so it is easy to cause airway obstruction after infection, leading to wheezing and hyperventilation.
