How to reduce the harm of haze to people? Now many cities across the country have been affected by the haze disaster, haze serious people can not see the road conditions, inhale too much particulate matter, but also affect our respiratory tract, threatening our health. So in the case of serious haze, how can we reduce the harm of haze to people?
1. Supplement vitamins and trace elements
Many vitamins and trace elements play an important role in preventing air pollution and maintaining cardiopulmonary health, including vitamin C, e, a, & beta; - carotene, and trace elements such as selenium and zinc. 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
Sufficient drinking water can replenish body fluid in time, increase blood circulation and promote metabolism. At the same time, keeping adequate drinking water and body fluid balance is helpful to form a complete sebum membrane on the skin and 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, help to improve the body's immune system. After 10 o'clock at noon, we can exercise properly to strengthen the physique and improve the immune function of the body.
4. Improve 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.) invaded by foreign bodies, and has the ability to identify and deal with mutant cells and virus infected cells in the body. Immune function is like the guardian of our human health. Only when our immunity is improved can we effectively prevent haze, radiation and other harm to us.
5. Reduce harmful gas as much as possible
It is the most direct way to reduce haze damage to reduce going out in haze days, especially for people with cardiovascular, cerebrovascular and respiratory diseases. When you must go out, remember to wear a mask, do not open the window, reduce the pollution to the respiratory tract. In the case of fog weather upgrade, try not to open the window. If you really need to open the window for ventilation, try to avoid the morning and evening haze peak hours when opening the window. You can open a seam of the window 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 have a 60% higher risk of lung cancer than ordinary people, and haze contains more harmful particles, so haze is more likely to cause cancer than smoking.
2. A variety of bacterial diseases
Because of the haze weather, the sun can not reach the earth, or the sun is weak. This will make the bacteria, viruses and microorganisms on the ground surface multiply rapidly, causing diseases such as allergy.
3. Prone to traffic accidents
Haze weather will reduce visibility, serious can only see a few meters away. It is very dangerous for pedestrians and vehicles on the road.
4. Injured blood vessel
Fog weather pressure is relatively low, people will have a restless feeling, blood pressure will naturally increase. In addition, in foggy days, the temperature is often low, and some patients with hypertension and coronary heart disease suddenly walk from warm indoor to cold outdoor. Blood vessels expand and contract with heat, which can also increase blood pressure, leading to stroke and myocardial infarction.
5. Brain injury
Haze not only damages organs, but also affects the nervous system. Experts have said that the 65th annual meeting of the American Geriatrics Association has come to a conclusion that if PM2.5 in the air increases by 10 μ g / m3, people's brain function will age for three years.
6. Lung injury
Haze has 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 lungs 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 condition were investigated. It was found that when PM2.5 increased by 10 μ g / m3, the mortality rate of patients would increase by 10% ~ 27%.
