What are the hazards of haze weather?

It is easy to get respiratory diseases in foggy days.

Winter fog is called "winter killer", and pollutants such as industrial waste gas, automobile exhaust, dust in the air, bacteria and viruses in the air attach to these water droplets. In people's daily life and travel, these substances will have an impact on the human respiratory tract, which may cause acute upper respiratory tract infection (cold), acute tracheobronchitis, pneumonia and asthma attacks, and induce or aggravate chronic bronchitis. In particular, children's respiratory mucosa of nose, trachea and bronchus is tender, and the number of alveoli is small, the development of elastic fibers is poor, and the interstitial development is vigorous, which makes them more susceptible to respiratory viruses. Being in foggy weather for a long time will cause tracheitis, laryngitis, pneumonia, asthma, rhinitis, conjunctivitis, allergic diseases, etc., which will have a certain impact on the growth and physique of children and adolescents. In addition, diabetic patients with poor air quality and poor resistance in foggy days are very likely to have lung and trachea infections, which will aggravate their condition.

Hazy weather is more likely to cause cancer than cigarettes.

In the past 30 years, the public smoking rate in China has been declining, but the prevalence of lung cancer has increased by more than four times. This may be related to the increase in haze days. Not only foggy days with very low visibility will have an impact on human health, but also foggy days and cloudy days will have the same problem.

Cloudy days induce cardiovascular and cerebrovascular diseases.

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.

Long-term haze is easy to induce psychological depression.

Hazy days also have a serious impact on 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. And cause pulmonary heart disease in chronic bronchitis. 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, 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. Therefore, patients with cardiovascular and cerebrovascular diseases must take medicine on time and handle it carefully.
