Main hazards of smog

In people's daily life and travel, some suspended substances will have an impact on human respiratory tract, which may cause acute upper respiratory tract infection, acute tracheobronchitis and pneumonia, asthma attack, induce or aggravate chronic bronchitis and so on. In particular, children's respiratory tract, trachea and bronchial mucosa are tender, 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.

If you stay in such foggy days for a long time, it will cause tracheitis, laryngitis, pneumonia, wheezing, rhinitis, conjunctivitis, allergic diseases and so on, which will have a certain impact on the growth, development 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.

1, harm to respiratory system

The composition of smog is very complex and small, which is invisible to the naked eye, but it is very lethal, mainly mineral particles, sea salt, sulfate, nitrate, organic aerosol particles, fuel and automobile exhaust. It will directly enter and adhere to the human respiratory tract and alveoli. Once it enters the human body, it will attack the human body, especially parents with chronic respiratory diseases such as bronchial asthma, chronic bronchitis, obstructive emphysema and chronic obstructive pulmonary disease, which can cause acute attack or acute exacerbation. Long-term exposure to this environment will also induce lung cancer.

2. Harm to cardiovascular system

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. In addition, the low pressure in dense fog will also affect people's mood, giving people a feeling of irritability. With the fluctuation of mood, blood pressure will also rise, which may also lead to stroke and myocardial infarction. Therefore, patients with cardiovascular and cerebrovascular diseases must take medicine on time and be careful to deal with this "environmental enemy".

3. Weakening ultraviolet rays leads to calcium deficiency.

Hazy weather will lead to layers of suspended matter in the air, which will weaken the intensity of ultraviolet rays reaching the ground. Some people are thinking, isn't this better? You can stop tanning. On the other hand, the weakening of ultraviolet rays, insufficient ultraviolet irradiation and insufficient vitamin D production in the body greatly reduce the absorption of calcium, which has the greatest impact on children. If it is serious, it may cause rickets in infants and slow down the growth and development of children. Do you still think this is a good thing?

4, causing bacterial diseases

Because of the smog, the sun can't shine on the earth, or the sunlight is very weak. We all know that the sun has a certain bactericidal effect. Once Grandpa Sun is away from our grandmother, bacteria, viruses and microorganisms on the surface of the earth will multiply rapidly, and their wanton behavior will cause some allergic diseases to the human body.

5, affect mental health

Ask yourself, will your mood follow the weather? I believe many people are no exception, because many things complement each other. If it is sunny that day, people's mood will suddenly get better. This is not speculation, but people's real thoughts and elegance! 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, stimulate or aggravate the state of psychological depression, and lack vitality in doing things.

6. The risk of cancer will increase.

As we all know, the probability of smokers suffering from lung cancer is 60% higher than that of ordinary people, which is a very shocking figure; But today's smog is even more terrible. Expert data show that smog contains more harmful particles, and smog is more likely to cause cancer than smoking. You can imagine what kind of concept this is!

7, affecting traffic safety

It is believed that when haze weather occurs, the visual visibility is very low, which will lead to many traffic accidents. At the same time, it is easy to cause traffic jams.
