What are the hazards of smog? Haze Harm and Prevention Sharing

Harm to cardiovascular and cerebrovascular systems: there are many pollutants in the air in foggy days and the air pressure is low, which is easy to induce acute attacks of cardiovascular diseases. When the fog is heavy, the moisture content is high. When people exercise outdoors, sweat is not easy to be discharged, which makes people feel chest tightness and blood pressure rise. Moreover, in foggy weather, the air pressure is relatively low, and people will feel irritable and their blood pressure will naturally rise. Particulate pollutants on cloudy days will not only cause myocardial infarction, but also cause myocardial ischemia or injury.

There is no doubt that smog is the most harmful to the respiratory system. The respiratory system has the most frequent contact with the external environment and the contact area is large. Hundreds of atmospheric particles can directly enter and adhere to the upper and lower respiratory tract and lungs of the human body, most of which will be inhaled by the human body. Secondly, the haze weather weakens the surface ultraviolet rays, which easily increases the activity of bacteria in the air. Fine particles can "carry" bacteria and viruses deep into the respiratory system, causing infection. May cause lung infection, and in severe cases may induce lung cancer.

It affects traffic safety, the visibility is very low in foggy days, and the air quality is poor, which is easy to cause traffic accidents.

We can reduce the harm of smog in the following ways.

Wearing masks has become a necessity for people in areas with severe smog. In order to prevent smog, wear a mask before going out in foggy days. Every day from 6: 00 to 1 1 is a time with serious pollution, which can reduce outdoor activities. Relatively speaking, the air at night is cleaner.

Eat more fruits and vegetables to enhance the body's self-detoxification function.

The diet in haze weather should choose light and digestible foods rich in vitamins, drink plenty of water and eat more fresh vegetables and fruits, which can not only supplement various vitamins and inorganic salts, but also moisten the lungs, remove dryness, eliminate phlegm and relieve cough, strengthen the spleen and tonify the kidney.

The most direct and effective way to reduce going out is to reduce going out, so choose the right weather to go out.
