If you are under hazy weather for a long time, some harmful aerosol particles may directly enter and adhere to the upper and lower respiratory tracts and lung lobes of the human body, causing rhinitis, bronchitis and other diseases. With the low air pressure in hazy weather, the oxygen content in the air has decreased, and people can easily feel chest tightness, which, together with cold stimulation, can easily lead to blood vessel spasm, blood pressure fluctuation and increased heart load. So, I’ll introduce you to the hazy weather precautions, I hope to provide you with some help!
Hazy weather precautions
1, easy to cause cardiovascular disease
Hazy weather is a cardiovascular disease patients “health killer”, especially the elderly with respiratory and cardiovascular diseases, foggy days are best not to go out, more should not be morning exercise, otherwise it may trigger the disease, and even heart attack, causing life-threatening. The reason why foggy days are “dangerous days” for patients with cardiovascular disease is because of the low air pressure when foggy, the oxygen content in the air has decreased, people can easily feel chest tightness, the morning wet and cold fog will also cause cold stimulation, which can easily lead to vasospasm, blood pressure fluctuations, increased heart load, etc.. At the same time, some pathogens in the fog can cause headaches, and even induce hypertension, cerebral hemorrhage and other diseases. Therefore, people with cardiovascular disease, especially the elderly and frail, should not go out in the foggy days, and not in the foggy days of morning exercise, in order to avoid danger.
2, go out to do protective measures
If you go out, you can wear a mask, which can effectively prevent dust particles from entering the body. Mask to cotton mask is the best, because some people are allergic to non-woven fabrics, while cotton masks are generally not allergic to people, and easy to clean. When you return from an outing, you should immediately wash your face and exposed skin.
3, hazy weather less open windows
Hazy weather in the morning and evening try not to open the window ventilation, it is best to wait for the sun to come out, the fog is almost dissipated and then open the window ventilation.
4, drink more tangerine tea
Tongkatang tea has the function of clearing fire and filtering lung dust, which can effectively assist the body in discharging PM2.5 particles and other harmful substances accumulated in the body.
5, eat light and drink more water
Diet should choose light and easy to digest and vitamin-rich food, drink more water, eat more fresh vegetables and fruits, which can not only replenish various vitamins and inorganic salts, but also play a role in moistening the lungs and removing dryness, expectorant and cough, and strengthening the spleen and kidney. Eat less stimulating food, eat more pears, loquats, oranges, tangerines and other foods to clear the lungs and resolve phlegm.
6, stop the morning exercise
Like the morning exercise had to stop your morning exercise. The amount of oxygen required by the body increases during morning practice, and as breathing deepens, harmful substances in the fog will be inhaled into the respiratory tract, thus endangering health. You can change to morning exercise after the sun comes out. You can also change to indoor exercise. From the time the sun comes out, the better time to exercise outdoors in winter is 9:00 am.
7.Ventilation and ventilation
Do not think that the hazy weather, indoor ventilation is not needed. Don’t close the windows too tightly. Home will have kitchen fumes pollution, furniture additives pollution, etc., such as no ventilation, dirty indoor air will also be hazardous to health. You can choose to open the windows for a short time at noon when there is more sunshine and less pollutants. Of course, in the case of escalating foggy weather, try not to open the window; if you do need to open the window for ventilation, you should try to avoid the morning and evening haze peak hours, you can open the window a crack ventilation, not to let the wind blow directly in, ventilation time each time to half an hour to an hour is appropriate. At the same time, the residents of the home to air conditioning heating, especially to pay attention to open the windows for ventilation to ensure adequate indoor oxygen.
8.Wear a mask to keep warm
Winter is already a high incidence of respiratory diseases, coupled with the recent air pollution is very serious, the number of small patients coming to the clinic has increased greatly. In addition to keeping warm, wearing a mask is also a good way to prevent respiratory diseases in the “foggy days”.
9, try to stay away from the road
The concentration of pollutants is highest during rush hour and at night when large cars enter the city. If you have to walk on the road because of commuting, then try to talk less, or bring a mask.
10.Drink tea that clears the lungs and moistens them
It is recommended that you can drink more rooibos tea. Luo Han Guo tea can prevent the foggy day inhalation of dirty air caused by itching in the throat, there is a good effect of lung moistening. Especially in the afternoon to drink the effect is better. Because the fog is thickest in the early morning, almost dissipated at noon, people inhale more dust impurities in the morning, drink in time to clear the lungs in the afternoon.
11, try to reduce the number of people to go to places
Poor air circulation in some places is easy to cause respiratory disease cross-infection. Hazy weather as much as possible to reduce going out, when going out can wear a cotton mask to prevent respiratory tract by foggy days “pollution”. Wash your face and exposed skin when you return from a trip, and also rinse your nasal passages with water.
12.Reduce going out
The elderly and children with weak resistance and susceptible people with respiratory diseases should try to reduce going out, or reduce outdoor activities, wear a mask to protect the body when going out, to prevent pollutants from the nose, mouth invasion of the lungs, after returning from going out, should immediately wash the face and bare skin.
13.Good personal hygiene
Fog looks mild, but it contains various acids, alkalis, salts, amines, phenols, dust, pathogenic microorganisms and other harmful substances, so you should wash your face and bare skin immediately after returning from a foggy day.
14, pay attention to indoor hygiene
Foggy weather, especially to pay attention to indoor hygiene. Remember to open the windows every day to ensure that the air is fresh. Clean the room in a timely manner, clean up hygiene corners, do not give germs to breeding ground.
15.Take preventive measures
To prevent the harm of haze and increase body resistance, people can also make their own ginger and red dates soup (5-6 grams of ginger, 10 grams of red dates, plus two bowls of water with brown sugar) to drink. This can enhance the body’s resistance to prevent fog damage.
16.Walking and driving with extra care
In moderate and heavy haze, visibility is low, poor vision, people driving, cycling and walking should be more careful, especially through intersections and unattended railroad crossings, slow down and obey traffic rules to avoid traffic accidents.
Hazards of haze
1, affect the health of the body
More fog means more dust in the air, which is harmful to human health. The composition of the haze is very complex, including hundreds of atmospheric particulate matter. Among them, those harmful to human health are mainly aerosol particles less than 10μm in diameter, such as mineral particles, sea salt, sulfate, nitrate, organic aerosol particles, etc., which can directly enter and adhere to the human upper and lower respiratory tracts and lung lobes. As most of the atmospheric aerosols in haze can be inhaled by human respiratory tract, especially submicron particles will be deposited in upper and lower respiratory tracts and alveoli respectively, causing rhinitis, bronchitis and other diseases, and long-term exposure to this environment will also induce lung cancer. In addition, because the sun’s ultraviolet light is the only way for the body to synthesize vitamin D, the weakening of ultraviolet radiation directly leads to a high incidence of pediatric rickets. In addition, ultraviolet light is nature’s main weapon to kill atmospheric microorganisms such as bacteria and viruses.
2.Impact on mental health
Foggy weather is prone to pessimism, if not timely adjustment, it is easy to lose control.
3, affect traffic safety
When foggy weather occurs, outdoor visibility is low, pollution persists, traffic is blocked and accidents occur frequently.
4.Impact on regional climate
It makes regional extreme weather events frequent and meteorological disasters one after another. More worryingly, haze also accelerates the early arrival of photochemical smog pollution from cities. Photochemical smog is a light blue smog, car exhaust and factory waste gas contains a large amount of nitrogen oxides and hydrocarbons, these gases under the action of sunlight and ultraviolet light, photochemical reactions will occur, producing photochemical smog. Its main components are a series of oxidants, such as ozone, aldehydes, ketones, etc. It is very toxic and has a strong irritating effect on the human body, which can cause breathing difficulties, vision loss, hand and foot convulsions in severe cases.
