How to prevent haze weather

Countermeasure 1: Go out less

Going less is the most effective way to protect yourself. According to the PM2.5-related epidemiological study conducted in Xi'an by Huang Wei, a researcher at the Center for Environment and Health, a cutting-edge interdisciplinary researcher at Peking University, and others published in the top international epidemiological journal "American Epidemiology" in 2012, after excluding After adjusting for factors such as age, gender, time effect and meteorological factors, when the PM2.5 concentration increases by 103 micrograms/cubic meter, the excess mortality risk of residents from all causes of death will increase by 2.29%, with a lag time of 1-2 days. The excess risk of death increased by cardiovascular and cerebrovascular diseases is even higher, at 3.08%.

If you must go out, do not ride a bicycle, avoid rush hour traffic and roads with a lot of driving, to avoid inhaling more chemical components. It is also best not to drive a private car and take public transportation more often to contribute to reducing PM2.5.

Countermeasure 2: Smoking less

Cigarettes, cigars and pipes will produce a lot of fine particulate matter in the PM2.5 category when they are not completely burned. Tobacco smoke contains more than 7,000 compounds. , including 69 carcinogens and 172 harmful substances, which will seriously harm the health of smokers themselves and those who inhale "second-hand smoke". In this hazy weather, it is even worse. Therefore, smokers should try to smoke as little as possible in recent days, whether they go out or stay indoors.

Countermeasure 3: Open fewer windows

Experts say that in hazy weather, try not to open windows. If you really need to open a window for ventilation, you should try to avoid the peak hours of morning and evening smog. You can open the window a little for ventilation, and the time is preferably half an hour to an hour at a time. At the same time, residents whose homes are heated by air conditioners should open windows for ventilation to ensure sufficient indoor oxygen. You can plant more green plants on your balcony, terrace, or indoors. Green crown-leaf plants such as pothos, dieffenbachia, and tiger orchid have relatively strong adsorption capacity because of their larger leaves. You can also use an air purifier. 80% of the air purifiers on the market mainly purify fine particles in the air and have a good adsorption effect on PM2.5, but you should pay attention to changing the filter element frequently when using it.

Countermeasure 4: Choose the right mask

Ordinary masks have little effect on air particles of 2.5 microns. To block PM2.5, medical N95 masks are needed, which are effective on 0.3 micron air particles. The particles can resist 95%, and can also have a certain effect in weather with explosive PM2.5 levels.

You must purchase a regular and qualified N95 mask that matches your face size. After taking it off, wait until the inside is dry and then fold it in half to prevent the moisture in the mask from breeding bacteria. It should not be worn for too long, and the elderly and people with cardiovascular disease should avoid wearing it to avoid difficulty breathing and causing dizziness.

Countermeasure 5: Good personal hygiene

After going out and entering indoors, wash your face, rinse your mouth, clean your nasal cavity in time, and remove the pollutant residues attached to your body to prevent PM2.5 from affecting the environment. Hazards to the human body. It is best to use warm water when washing your face to help wash away the particles on your face. When cleaning the nasal cavity, you can use a clean cotton swab dipped in water to clean it repeatedly, or you can repeatedly use your nose to gently absorb water and blow your nose quickly, and avoid choking. In addition to facial cleansing, exposed parts of the body should also be washed.

Countermeasure 6: Eat a light diet

You can also eat more tofu, milk and other foods. In addition, homemade throat tea is also a good choice, which can solve the problems of dry throat and cough while reducing the harm of air pollution to the lungs. The raw materials are: 3 grams each of dendrobium, lily, and Ophiopogon japonicus, 2 jujubes, and 2 rock sugar. Usage: Add 150 ml of boiling water and drink. One ingredient can be brewed 2-3 times.

That’s it, dear...
