What are the dangers of smog? Sharing on the dangers and prevention of smog

Harm to the cardiovascular and cerebrovascular systems: There are many pollutants in the air and low air pressure in haze days, which can easily induce acute attacks of cardiovascular diseases. When there is heavy fog, the water vapor content is very high. When people do outdoor activities and exercise, sweat is not easily discharged, causing chest tightness and increased blood pressure. Moreover, when the pressure is relatively low in dense fog, people will feel irritable and their blood pressure will naturally increase. Particulate pollutants in hazy days can not only cause myocardial infarction, but also cause myocardial ischemia or damage.

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 lung lobes of the human body, and most of them will be inhaled by the human body. Secondly, haze weather causes the weakening of ultraviolet rays near the ground, which can easily increase the activity of germs in the air. Fine particles can "carry" bacteria and viruses deep into the respiratory system, causing infection. It may cause lung infection, and in severe cases, it may induce lung cancer.

It affects traffic safety. The visibility in haze weather is very low and the air quality is poor, which can easily cause traffic accidents.

We can use the following methods to reduce the harm of smog.

Wear a mask. Masks have become a must-have for people in areas with severe smog. In order to prevent smog, you should first wear a mask before going out in heavy fog. From 6 to 11 o'clock every day, which is the time when pollution is more serious, you can reduce your outdoor activities. Relatively speaking, the air at night is cleaner.

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

In haze weather, you should choose foods that are light, easy to digest and rich in vitamins, drink more water, and eat more fresh vegetables and Fruits can not only supplement various vitamins and inorganic salts, but also have the functions of moistening the lungs and removing dryness, eliminating phlegm and relieving coughs, and strengthening the spleen and kidneys.

Reduce going out. The most direct way to reduce going out is also the most effective way, so go out in good weather.
