1, reduce the number of trains.
In foggy days, indoor air quality is better than outdoor air quality. We should reduce the frequency of going out. If you must go out, you should avoid the rush hour of traffic jam and the road with many cars and avoid inhaling more chemicals. It is also best not to drive a private car, but to take public transportation to contribute to reducing PM2.5
Step 2 wear a mask when you go out
It is essential to wear a mask in foggy days. Wearing a mask can prevent the nose and mouth from directly contacting the smog, which can effectively prevent dust particles from entering the body.
Choose the right mask. Ordinary masks have little effect on 2.5 micron airborne particles. To stop PM2.5, a medical N95 mask is needed, which can resist 95% of 0.3 micron particles and play a certain role. To buy a formal and qualified N95 mask that matches your face size, you should wait until it is dry and fold it in half to prevent the breathing moisture from breeding bacteria on the mask. It should not be worn for too long, and the elderly and patients with cardiovascular diseases should avoid wearing it to avoid dizziness caused by dyspnea.
3. Do a good job in personal hygiene
In foggy days, it is also essential to do a good job of cleaning, especially when you come in from the outside, and you need to clean your face and nose. Some pollutants will enter these two parts, causing harm. It is best to use warm water when washing your face, which is beneficial to wash off the particles on your face. When cleaning the nasal cavity, you can repeatedly clean it with a clean cotton swab dipped in water, or repeatedly absorb water with your nose to blow your nose quickly and avoid choking. In addition to face cleaning, bare parts of the body should also be cleaned.
4. Open the window less in foggy days
Try not to open the window in foggy weather. If you really need to open the window for air, don't open the window immediately after getting up in the morning. You can wait until noon, when the sun rises, and open the window, so as to avoid the harm of smog to your body. Try to avoid the morning and evening smog peak hours, and the ventilation time should be half an hour to one hour at a time. At the same time, friends who use air conditioning for heating at home should pay attention to window ventilation to ensure adequate indoor oxygen. You can plant a variety of green plants on your balcony, terrace and indoors, such as green crown-leaf plants such as green radish, evergreen and tiger orchid, because of their large leaves and strong adsorption capacity. You can also use an air purifier or something.
5, light diet, drink plenty of water, eat more fruits and vegetables.
The diet in foggy days should choose light and digestible foods rich in vitamins, drink plenty of water and eat more fresh vegetables and fruits, which can not only supplement various vitamins and inorganic salts, but also play a role in moistening the lungs, resolving phlegm, relieving cough, strengthening the spleen and tonifying the kidney. Eat less irritating food and eat more pears, loquats, oranges, oranges and other foods. In foggy days, a light diet can better regulate the body.
Step 6 smoke less
Cigars, cigars and pipes will produce a large number of fine particles belonging to the category of PM2.5 if they are not completely burned. Tobacco smoke contains more than 7000 compounds, including 69 carcinogens and 172 harmful substances, which will seriously harm the health of smokers themselves and those who inhale "second-hand smoke", especially in this smog weather. Therefore, smokers should smoke as little as possible whether they go out or stay indoors.
I hope the above contents will help everyone's health. This winter, we should reasonably prevent smog, do a good job of protection and prevent diseases. May you have a healthy body and have a pleasant winter!
