What harm does smog do to our health?
1. Smoky weather can easily make asthma relapse. Including bronchial asthma, bronchitis, allergic rhinitis, variant cough, etc., which are mostly related to the recent temperature drop and haze weather. In foggy days, dust and smoke are floating in the air, and dust mites may also be suspended in the fog. Inhalation of these allergens by patients with bronchial asthma will stimulate the respiratory tract and cause asthma symptoms such as cough, sulking and poor breathing. Every time a person breathes, about 500,000 particles are inhaled into the depths of the lungs, but in polluted air, the inhaled particles are 100 times more than this.
2. Smog weather is a "health killer" for patients with cardiovascular diseases, especially the elderly with respiratory diseases and cardiovascular diseases. It is best not to go out in foggy days, and it is not suitable for morning exercise, otherwise it may induce diseases and even heart attacks, which may be life-threatening.
3. The smog weather continues, and the air quality decline is not a new phenomenon this year. In recent years, every autumn and winter, especially after winter, the central and eastern regions of China will encounter similar situations from time to time. Although there are some meteorological factors, the most important thing is the consequences of extensive and disorderly development. It should be noted that smog is not ordinary air pollution, but it may pose a great threat to the public's life and health. According to official statistics, from 65438 to 0952, more than 4000 people were killed in heavy fog in London. According to environmental experts, smog may replace smoking as the primary cause of lung cancer.
4. Hazy days have a serious impact on human cardiovascular and cerebrovascular diseases, which will hinder normal blood circulation, lead to cardiovascular diseases, hypertension, coronary heart disease, cerebral hemorrhage, and may also induce angina pectoris, myocardial infarction and heart failure.
Chronic bronchitis is caused by cor pulmonale. In addition, when the air pressure is relatively low in foggy weather, people will feel irritable and their blood pressure will naturally rise. On the other hand, the temperature is often low in foggy days, and some people have high blood pressure and coronary heart disease.
When a patient suddenly walks from a warm room to a cold room, blood vessels expand with heat and contract with cold, which will also increase blood pressure, leading to stroke and myocardial infarction. Therefore, patients with cardiovascular and cerebrovascular diseases must take medicine on time and handle it carefully.
Experts point out that continuous foggy days have an impact on people's psychology and body. Psychologically speaking, foggy days will give people a feeling of depression, which will stimulate or aggravate the state of psychological depression. In addition, due to the weak light and low air pressure in foggy days, some people will feel lazy and depressed in foggy days.
