Anonymous users2024-02-06According to experts, the fog seems to be mild, but it contains more than 20 kinds of fine particles and toxic substances that are harmful to the human body, including acids, alkalis, salts, amines, phenols, etc., as well as dust, pollen, mites, influenza viruses, tuberculosis bacilli, pneumococcus, etc., and its content is dozens of times that of ordinary atmospheric water droplets. What are the effects of fog on human health? How should we respond?
1. Foggy weather is prone to respiratory diseases Winter fog is known as the "winter killer", coupled with pollutants such as industrial exhaust, automobile exhaust, dust in the air, bacteria and viruses in the air, attached to these water droplets, people in daily life and travel, these substances will have an impact on the human respiratory tract, may cause acute upper respiratory tract infection (cold), acute tracheobronchitis and pneumonia, asthma attack, induce or aggravate chronic bronchitis, etc. In particular, the mucous membranes of the respiratory tract, nose, trachea and bronchi are soft, and the number of alveoli is small, the development of elastic fibers is poor, and the interstitial development is vigorous, making them more susceptible to respiratory virus infection. Being in foggy weather for a long time can cause tracheitis, laryngitis, pneumonia, asthma, rhinitis, ocular conjunctivitis and allergic diseases, which have a certain impact on the growth and development of young children and adolescents and their physique.
In addition, diabetic patients with poor air quality and poor immunity in foggy weather are very likely to have lung and tracheal infections that will aggravate their condition. 2. Hazy weather is more likely to cause cancer than cigarettes Zhong Nanshan, academician of the Chinese Academy of Engineering and director of the Guangzhou Institute of Respiratory Diseases, once pointed out at a forum that in the past 30 years, the smoking rate of the public in China has been declining, but the prevalence of lung cancer has increased by more than four times. This may have something to do with the increase in smog days.
Not only can dense fog and very poor visibility affect human health, but sometimes foggy and sometimes cloudy weather can also have the same problem. 3. Haze weather induces cardiovascular and cerebrovascular diseases Haze days have a very serious impact on human cardiovascular and cerebrovascular diseases, which will hinder normal blood circulation, lead to cardiovascular disease, hypertension, coronary heart disease, cerebral hemorrhage, may induce angina, myocardial infarction, heart failure, etc., and cause chronic bronchitis to cause cor pulmonale. In addition, the pressure in dense fog weather is relatively low, and people will have a feeling of irritability, and blood pressure will naturally increase.
On the other hand, foggy days tend to have low temperatures, and some patients with hypertension and coronary heart disease suddenly walk from the warm indoor to the cold outdoors, and the blood vessels expand and contract, which can also increase blood pressure, leading to stroke and myocardial infarction. Therefore, patients with cardiovascular and cerebrohematologic diseases must take medicine on time and deal with it carefully, this answer is taken from "Shiyang Electromechanical", if there is any infringement, please contact to delete.
