Haze Haze Harm and Prevention and Cure: With the over-exploitation and construction of the natural environment, the environment we live in has become smog. Especially in some big cities, smog is more common. Let's take a look at the harm of smog and our views on the prevention and control of smog.
Haze and its prevention and control 1 haze
1, affecting respiratory tract
Harmful fine particles and toxic substances contained in smog are easily inhaled into the human body, and directly enter the throat and bronchus from the nostrils, which interferes with the gas exchange in the human lungs. When it enters the throat, it is easy to cause inflammation. When it affects the bronchi, it will affect the normal gas exchange in the lungs and easily lead to respiratory diseases such as acute rhinitis, bronchitis and bronchial asthma. Patients with respiratory diseases themselves are easy to relapse and aggravate their illness in foggy days.
2, affecting the cardiovascular and cerebrovascular systems.
There are many pollutants in the air in haze weather, especially in low-pressure weather, which easily affects the normal blood circulation of human body and easily induces diseases such as heart disease, hypertension and coronary heart disease. Especially when going out, outdoor cold is easy to cause blood vessels to expand with heat and contract with cold, leading to an increase in blood pressure.
3. Carcinogenesis
There are as many as 20 kinds of harmful fine particles and toxic substances in haze weather. Among them, many carcinogenic substances, such as aromatic hydrocarbons, may lead to cancers such as lung cancer, especially in places with serious industrial pollution, and people are at higher risk of cancer.
4. Affect mental health
Hazy weather with poor light and low air pressure on people's heads can easily lead to mental fatigue, depression and pessimism, and easily lead to mild depression.
5. Impact on traffic
Hazy weather is characterized by heavy fog in the atmosphere, low visibility and poor air quality, which can easily lead to traffic jams and even traffic accidents.
Preventive measures of smoke
1 to ensure indoor air quality. If people stay indoors for a long time, the indoor air quality will seriously affect people's health. Negative ion air purification device can be selected, and negative ions can be combined with particulate pollutants in the air to coagulate and settle. Ecological negative ion generation chip technology can improve purification efficiency and realize ultra-micro purification. The pollutants entering the room are mainly ultrafine particles such as PM2, 5, PM 1, which are difficult to be filtered by ordinary air purifiers.
2, wear a mask when going out, it is best to avoid staying outdoors for a long time in foggy days, and wear a mask if you need to go out. Mask can prevent poisonous fog from invading human body through nose and mouth to a certain extent, and reduce the harm of smog to human body. Try to choose a cotton mask, and you can wash your nose with clean water when you come back.
3. Reduce the ventilation of doors and windows to prevent the harm of smog. Usually, we should pay attention to reducing the ventilation time of windows, and close the doors and windows if possible. This is because a large number of pollutants in the air are not easy to disperse in foggy days. If you open the doors and windows, it is easy to cause pollutants to enter the room and cause physical discomfort.
My opinion on haze and its prevention and control 2 haze haze.
1, lung injury
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.
2. Hurt my heart
Harvard University School of Public Health has proved that particulate pollutants on cloudy days will not only cause myocardial infarction, but also cause myocardial ischemia or injury. The United States investigated 20,000 to 50,000 people with heart disease or poor heart condition, and found that with the increase of PM2 and 5, the mortality rate of patients would increase by 10 μ g cubic meter.
Step 3 damage blood vessels
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. When the fog is heavy, the water vapor content is high. When people exercise outdoors, sweat is not easy to be discharged, which makes people feel chest tightness and blood pressure rise.
4, hurt the skin
Skin also has respiratory function. In clean air, the skin will be very comfortable and moist, but in a dirty environment, the skin will be very uncomfortable.
5. Brain injury
Smog not only harms organs, but also affects the nervous system invisibly. Zhong Nanshan once introduced that the 65th annual meeting of the American Geriatrics Association came to a conclusion that if PM2 and PM5 in the air increase by 10 μ g cubic meter, people's brain function will age for three years.
6. Injury of reproductive system and urinary system
The influence of smog on semen quality is mainly manifested in the later stage. Inhalable substances in smog enter human blood circulation and gradually accumulate in various organs of human body, including scrotum in semen factory.
Prevention methods of smoke
1, go out less: going out less is the most effective way to protect yourself. If you must go out, don't ride a bike, avoid the rush hour of traffic jam and the sections where you drive a lot, and avoid inhaling more chemicals. It's best not to drive a private car, but to take public transport to contribute to reducing PM2 and PM5.
2. Wear a mask when going out: If you can wear a mask when going out, it can effectively prevent dust particles from entering the body. Cotton masks are the best because some people are allergic to non-woven fabrics, while cotton masks are generally not allergic and easy to clean.
3. Personal hygiene: wash your face, rinse your mouth and clean your nasal cavity in time after going out, and remove the pollution residue attached to your body to prevent the harm of PM2 and 5 to human body.
4. Open the window less in foggy days: Experts say that in foggy weather, try not to open the window. If you really need to open the window for ventilation, you should try to avoid the morning and evening smog peak hours, and open the window for ventilation for half an hour to one hour at a time.
Haze prevention and control 3 10 It is recommended to help you resist smog.
1, try not to go out, especially avoid outdoor morning exercises.
When the fog comes, the air pressure is low, and the oxygen content in the air drops, which makes people feel chest tightness and discomfort. Wet and cold fog in the morning can easily lead to vasospasm, blood pressure fluctuation and increased heart load. It is best not to go out in foggy days, and it is not suitable for exercise, so as not to induce angina pectoris, cerebral hemorrhage and other diseases.
2. Wear professional dust mask when going out.
Because the fine particles are too small, cotton gauze masks on the market only have dust-proof function, which can't stop PM2 and PM5. The nationally recognized dust masks of KN90, KN95 and N95 can filter fine particles to a certain extent and play a good role in protecting most bacteria and germs.
3. Clean up after going out.
When you come back from foggy days, you should immediately clean your face, nose and bare skin, and put on clean clothes to avoid bringing fine particles into the room and aggravating indoor air pollution.
4. Have a light diet and drink plenty of water
In the smog season, patients with cardiovascular diseases should eat light food, drink more water, eat more fresh fruits and vegetables, and eat less irritating food. You can eat pears, oranges, radishes, loquats, lilies, lotus seeds and other foods that clear the lungs and resolve phlegm.
5. Drink "Qingfei Dusting" tea properly.
Tung Platycodon Tea, Tung Ginseng Tea, Tung Platycodon Granules and Tanggeng Decoction have the functions of clearing fire and filtering lung dust, which can enhance the ability of alveolar cells to expel toxic fine particles and effectively assist the human body to expel harmful substances such as PM2 and PM5 particles accumulated in the body.
Step 6 take medicine properly
Under the guidance of doctors, patients with cardiovascular diseases can take some cardiovascular drugs to protect vascular endothelium, inhibit vasospasm, stabilize plaque, prevent plaque rupture, prevent myocardial infarction and stroke, and protect heart health from dense fog.
7. Open the window less in foggy days
People spend 70% ~ 90% of their time indoors every day, so indoor PM2 and PM5 are more harmful. It is wrong to close doors and windows in foggy weather, because indoor air needs to be circulated. But don't open the window in the morning and evening for ventilation, because the pollution is the heaviest at this time. It is best to open the window for ventilation after the sun comes out (around noon).
8. Smoke less or not.
Cigarette smoke contains a lot of PM2 and PM5, which are directly and indirectly harmful to human body, and should be smoked less or not. If you can't stop people around you from smoking, try to stay away from the smoky environment.
9. Appropriate planting of green plants
Green plants with large leaf area, such as radish, Solanum nigrum, Evergreen and bamboo, can absorb harmful gases and PM2 and PM5, and reduce the concentration of inhalable particles in indoor environment.
10, using dust removal equipment.
Air purifiers can be used to filter PM2 and PM5, and ultrasonic atomizers, indoor water curtains, pools and fish tanks can also be used to absorb hydrophilic PM2 and PM5 in the air and purify the air.
