What should I pay attention to in foggy days?

Smog weather has the greatest impact on the respiratory system, which has become the common sense of most people. 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. Zhong Nanshan pointed out that the annual increase of lung cancer in Beijing is 2.42%, which is the fastest among all tumors. Among them, Chaoyang District, Fengtai District and Shijingshan District have the highest incidence of lung cancer, which is consistent with the regional pollution level, indicating that smog is related to the incidence of lung cancer.

Injured blood vessel

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. For example, when the fog is heavy, the water vapor content is high. If people exercise outdoors, sweat is not easy to be discharged, which causes people to feel chest tightness and blood pressure to rise. Moreover, in foggy weather, the air pressure is relatively low, and people will feel irritable and their blood pressure will naturally rise. In addition, 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, people who encounter smog weather, the elderly and cardiovascular diseases should be less outdoors and eat less irritating food.

Harm the skin

Because the skin also has breathing function, it will be very comfortable and moist in clean air, but it will be very uncomfortable in dirty environment. If you are in foggy weather for a long time, you can apply some protective cream, cream and the like, and then wash it off after work. Moreover, it is necessary to wash your face frequently.
