Countermeasure 1: Reducing the exit at home is the most effective way to protect yourself. According to the international top-level epidemiological journal "American Epidemiology" published in 2012, the research and development of PM2.5 related epidemiology in Xi'an, a researcher at the Center for Environmental and Health Research at Peking University's Frontier Interdisciplinary Research Institute, was excluded. After the influencing factors such as age, gender, time effect and meteorological factors, when the PM2.5 concentration increases by 103 μg/m3, the excess death risk of all deaths of residents will increase by 2.29%, and the lag time is 1-2 days. The increased risk of excess death from cardiovascular and cerebrovascular disease is higher at 3.08%.
If you must go out, don't ride a bicycle, avoid the peak of traffic congestion and drive more roads to avoid inhaling more chemicals. It is also best not to drive private cars, take public transport, and contribute to reducing PM2.5.
Countermeasure 2: Less smoke, cigars and pipes will produce a lot of fine particles belonging to PM2.5 in the case of incomplete combustion. Tobacco smoke contains more than 7,000 compounds, including 69 carcinogens and 172 harmful substances. It will seriously harm the smokers themselves and the physical health of the inhaled "second-hand smoke" audience. Under such ashes, it is even worse. Therefore, smokers should smoke as little as possible in the past few days, whether they are going out or staying indoors.
Countermeasure 3: Close the door and window experts said that in the ashes weather, try not to open the window. If you really need to open the window and breathe, you should try to avoid the smog peak hours in the morning and evening. You can open the window and ventilate the window for half an hour to one hour. At the same time, residents who use air-conditioning to warm their homes should pay attention to the ventilation of the windows to ensure sufficient oxygen in the room. Green crown plants such as green plants, green radish, evergreen, and tiger peony can be planted in their own balconies, terraces and indoors. Because of their large leaves, the adsorption capacity is relatively strong. It is also possible to use an air purifier. 80% of the air purifiers on the market are mainly used to purify fine particles in the air, and have a good adsorption effect on PM2.5, but it is necessary to pay attention to changing the filter core during use.
Countermeasure 4: Pay attention to hygiene. When you go out indoors, you should wash your face, rinse your mouth, clean your nose, and remove the pollution residue attached to your body to prevent PM2.5 from harming the human body. It is best to use warm water when washing your face, which is good for washing off the particles on your face. When cleaning the nasal cavity, you can use a clean cotton swab to wash the water repeatedly, or repeatedly use the nose to gently absorb water and quickly rub your nose, while avoiding coughing. In addition to facial cleansing, the exposed parts of the body are also cleaned.
Countermeasure 5: Eat light and eat less irritating foods, eat more fresh vegetables and fruits, can supplement various vitamins and inorganic salts, and also can moisten the lungs to remove dryness, relieve cough, spleen and kidney. You can also eat more food such as tofu, milk and so on. In addition, homemade throat tea is also a good choice to solve the problem of dry and coughing of the throat, while reducing the harm of air pollution to the lungs. The raw materials are: 3 grams of stone carp, lily, and Ophiopogon japonicus, 2 jujubes, and 2 crystal sugar. Usage: Add 150 ml of boiling water and soak. One can be brewed 2 to 3 times.
Responding to PM2.5
Core Tip: PM2.5 is once again making a comeback. Facing the sky and the loess, the home is at home, paying attention to hygiene, and smoking is the most basic and effective method.
