How to 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 heart and lung health, including vitamin C, e, a, β - 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
Adequate drinking water can timely supplement body fluid, increase blood circulation and promote metabolism. At the same time, maintaining adequate drinking water and body fluid balance can 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 adequate repair and adjustment, which is helpful to improve the human immune system. After 10 o'clock in the afternoon, you can exercise properly to enhance your physique and improve your immune function.
4. Improve self immunity
Improving our personal immunity is a more reliable and powerful way to prevent and control haze damage. Immunity is the human body's own defense mechanism, which is used to identify and eliminate any foreign matter (virus, bacteria, etc.) invaded by foreign bodies. It has the ability to identify and deal with mutated cells and virus infected cells in the body. Immune function is like a guard to protect our health. Only when immunity is improved can we effectively prevent haze, radiation and other harm to us.
5. Try to reduce harmful breath
The most direct way to reduce the harm of haze is to reduce going out in haze days, especially for those with cardiovascular and respiratory diseases. When you have to go out, remember to wear a mask, do not open the window, reduce the pollution of the respiratory tract. When the fog weather is upgraded, try not to open the window. If it is really necessary to open the window for ventilation, try to avoid the fog and haze peak time in the morning and evening. You can open the window to ventilate without letting the wind blow in directly. The ventilation time should be half an hour to one hour each time.
What is the harm 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. Causing various bacterial diseases
Because of haze weather, the sun can not reach the earth, or the sun is weak. This will make the surface of the bacteria, viruses and microorganisms rapidly propagate, causing allergies and other diseases.
3. Prone to traffic accidents
Haze can reduce visibility, and can only see a few meters away. It is very dangerous to pedestrians and vehicles on the road.
4. Injured blood vessels
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 out of the warm room to the cold outdoor, and the blood vessels are hot and cold, which can also make the blood pressure rise and lead to the occurrence of stroke and myocardial infarction.
5. Brain injury
Haze not only damages organs, but also affects the nervous system invisibly. Experts have introduced that the 65th annual meeting of the American Geriatrics Association has concluded that if PM2.5 in the air increases by 10 μ g / m3, the brain function of people will be aging for three years.
6. Lung injury
It has become a consensus that haze has the greatest impact on 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, 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 if PM2.5 increased by 10 μ g / m3, the mortality of patients would increase by 10% ~ 27%.
