How to reduce the harm of haze to people
1. Supplement vitamins and microelements
Many vitamins and microelements, including vitamin C, e, a, β - carotene, selenium and zinc, play an important role in preventing air pollution and maintaining heart and lung health. They have the function of regulating immunity. Foods rich in these vitamins and trace elements include fresh fruits, vegetables, grains, meat and seafood.
2. Ensure drinking water
Full drinking water can timely supplement body fluids, increase blood circulation and promote metabolism. At the same time, maintaining adequate drinking water and body fluid balance will help the skin to form a complete sebum membrane, which has a certain resistance to air pollutants entering through skin contact.
3. Get enough sleep and exercise
High quality sleep can make the immune system get enough repair and adjustment, and help to improve the immune system of human body. After 10 o'clock at noon, you can exercise properly, strengthen your constitution and improve your immune function.
4. Improve self immunity
Improving our personal immunity is a more stable and powerful way to prevent and control haze damage. Immunity is the body's own defense mechanism, which is used to identify and eliminate any foreign body (virus, bacteria, etc.) that has the ability to recognize and deal with the mutant cells and virus infected cells in the body. Immune function is like a guardian of our health. Only when our immunity is improved can we effectively prevent the harm of haze, radiation and so on.
5. Try to reduce the harmful gas inhaled
Reducing going out in haze days is the most direct way to reduce haze damage, especially for those with cardiovascular and cerebrovascular diseases and respiratory system diseases, we should try to avoid going out as much as possible. When you have to go out, remember to wear a mask, do not open the window to reduce the pollution of the respiratory tract. Do not open the window as much as possible in case of heavy fog weather upgrading. If it is really necessary to open the window for ventilation, try to avoid the haze peak period in the morning and evening when opening the window. You can open the window with a seam for ventilation to prevent the wind from blowing in directly. The ventilation time should be half an hour to one hour at a time.
What are the hazards of haze to human body
1. Increased risk of cancer
As we all know, smokers are 60% more likely to develop lung cancer than ordinary people, and haze contains more harmful particles, so haze is more likely to cause cancer than smoking.
2. Causing various bacterial diseases
Because the sun can't reach the earth in the haze weather, or the sun is weak. In this way, the bacteria, viruses and microorganisms on the surface of the ground will rapidly multiply, causing allergies and other diseases.
3. Prone to traffic accidents
Haze weather will reduce the visibility, and only a few meters can be seen seriously. It is very dangerous for pedestrians and vehicles on the road.
4. Blood vessel injury
Dense fog weather pressure is relatively low, people will have a feeling of irritability, blood pressure will naturally increase. In addition, the temperature is often low in foggy days. Some patients with hypertension and coronary heart disease suddenly go from warm indoor to cold outdoor. The blood vessels expand and contract with heat, which can also increase blood pressure, leading to stroke and myocardial infarction.
5, hurt the brain
Haze not only damages organs, but also affects the nervous system. Experts have introduced that there is a conclusion at the 65th annual meeting of the American Geriatric Society that if PM2.5 in the air is increased by 10 μ g / m3, the brain function of people will age for 3 years.
6, lung injury
Haze days have the greatest impact on the respiratory system, which has become the consensus 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 lung lobes of the human body, and most of them will be inhaled by the human body. In the United States, 25000 people with heart disease or poor heart were investigated. It was found that the mortality of patients increased by 10% ~ 27% after PM2.5 increased by 10 μ g / m3.
