Does foggy weather affect people's health?

Fog has an impact on people's health, and fog is harmful to people, mainly because the components of condensation nuclei in fog are harmful to people. The condensation nucleus of fog can contain a large number of impurities and chemical particles. In a sense, under certain atmospheric conditions, the pollution components in the atmosphere are the same as the harmful components in the fog, and the high degree of air pollution is often harmful in the fog.

Poisonous fog kills knives in autumn and winter. Fog is a condensation phenomenon, which occurs when water vapor is abundant in the air. Fog seems mild, but it contains various harmful substances such as acid, alkali, salt, amine, phenol, dust and pathogenic microorganisms. Its content is dozens of times that of ordinary atmospheric water droplets, which poses a great threat to human health.

Fog has the greatest influence on the respiratory system, which can cause acute upper respiratory tract infection, acute tracheitis, bronchitis, pneumonia, asthma and other diseases. In addition, persistent fog will increase the burden on the circulatory system of the elderly, which may induce angina pectoris, myocardial infarction and heart failure. And cause pulmonary heart disease in chronic bronchitis.

Heavy fog will aggravate the condition of cardiovascular patients. This is because, on the one hand, the air pressure in dense fog is relatively low, people will feel irritable and their blood pressure will naturally rise. On the other hand, in foggy days, the temperature is often low. Some patients with hypertension and coronary heart disease suddenly go from warm indoor to cold outdoor, and blood vessels expand with heat and contract with cold, which will also increase blood pressure, leading to stroke and myocardial infarction. The air pollution is serious in foggy days, the fog is getting thicker in early winter, the air quality is poor, and the diabetic patients with poor resistance are very likely to have lung and trachea infections, which will aggravate the condition.

In foggy days, due to the decrease of sunshine, insufficient ultraviolet radiation for children, insufficient production of vitamin D in the body, and greatly reduced absorption of calcium, rickets in infants and young children will be seriously caused, which will slow down the growth and development of children. In addition, due to the weak light and low air pressure in foggy days, some people will feel lazy and depressed in foggy days.
