1. The difference between fog and haze
Smog is the collective name for fog and haze. But fog is fog, haze is haze, and the difference between fog and haze is very big. Fog is an aerosol system composed of a large number of tiny water droplets or ice crystals suspended in the air near the ground. It mostly appears in autumn and winter and is the product of condensation (or sublimation) of water vapor in the air near the ground. The existence of fog will reduce the transparency of the air and worsen the visibility. If the horizontal visibility of the target object is reduced to less than 1000 meters, the weather phenomenon of water vapor condensation (or sublimation) suspended in the air near the ground is called fog; and This phenomenon when the horizontal visibility of the target object is between 1,000 and 10,000 meters is called light fog or haze. When fog is formed, the atmospheric humidity should be saturated. If there are a large number of condensation nuclei, the relative humidity may not necessarily reach 100%, and saturation may occur. Since the light scattered by fog composed of liquid water or ice crystals has a large relationship with wavelength, the fog looks milky white. Or bluish white and gray.
Haze is composed of dust, sulfuric acid, nitric acid, organic hydrocarbons and other particles in the air. It can also make the atmosphere turbid, blur vision and cause visibility to deteriorate. If the horizontal visibility is less than 10,000 meters, the visual range obstruction caused by this non-aqueous aerosol system is called haze or haze.
2. Haze-related diseases
(1) Upper respiratory tract infection
The persistent haze weather has enveloped more than 10 provinces across the country. A large number of harmful substances such as dust particles and smoke particles floating in the air can cause harm to the human respiratory tract. A large number of particles, dust, pollutant viruses, etc. floating in the air, once inhaled by the human body, will irritate and destroy the respiratory mucosa, causing nasal cavity changes. It gets dry, destroys the defense ability of respiratory mucosa, and bacteria enters the respiratory tract, easily causing upper respiratory tract infection.
(2) Bronchial Asthma
During haze weather, the level of air pollution is heavier than usual, and bacteria and viruses are often contained in the air, which can easily lead to the spread of infectious diseases and various diseases. occur. In particular, air pollutants in cities are not easy to diffuse, which aggravates the toxicity of sulfur dioxide, carbon monoxide, nitrogen oxides and other substances, which will seriously threaten human life and health. During haze weather, dust and smoke float in the air, and dust mites may also be suspended in the mist. Bronchial asthma patients inhale these allergens, which will irritate the respiratory tract and cause asthma symptoms such as coughing, stuffiness, and difficulty breathing.
(3) Lung cancer
Professor Kan Haidong from the School of Public Health of Fudan University said that the incubation period of lung cancer ranges from a few years to decades. Young children suffering from lung cancer will It is likely to be related to genetic factors and gene mutations. However, compared with adults, children's height determines that they are indeed more affected by car exhaust and road dust. This is fully recognized by the medical community. Because children's breathing zone is just around the height of exhaust gas, and at the same time, children's respiratory exposure per unit weight is higher than that of adults, which makes them more susceptible, so they are more affected by pollution gases such as exhaust gas and smog. In addition, children's body organs are not fully developed, and the damage caused by pollution gas invasion is also greater.
(4) Conjunctivitis
Experts say that particles in the air in haze days adhere to the cornea, which may cause corneal and conjunctivitis, or aggravate the patient's keratitis and conjunctivitis. illness. The number of patients with keratitis and conjunctivitis has increased significantly, including the elderly and children, as well as office workers who spend all day in front of computers. People experience much the same symptoms: dry eyes, soreness, stinging, redness, and irritation.
(5) Rickets in children
Preliminary research has found that in addition to causing an increase in the incidence/hospitalization rate of respiratory diseases, haze weather can also have some indirect effects on human health. The occurrence of haze will weaken ultraviolet radiation. If haze occurs frequently, it will affect the body's synthesis of vitamin D, leading to a high incidence of rickets in children and increasing the activity of infectious bacteria in the air.
3. Self-prevention in haze weather
(1) Open windows less often in haze weather
It is not recommended to open windows in the morning and evening for ventilation in haze weather. It is best to Wait until the sun comes out before opening the windows for ventilation.
(2) Wear a mask when going out
If you go out, you can wear a mask
This can effectively prevent dust particles from entering the body. Cotton masks are best because some people are allergic to non-woven fabrics, while most people are not allergic to cotton masks and they are easy to clean. After returning from going out, you should wash your face and exposed skin immediately.
(3) Drink more Tong Platycodon tea, Tung ginseng tea, Tong Platycodon granules, Platycodon soup, etc.
"Lung-clearing and dust-removing" tea drinking Tong Platycodon tea can clear fire and filter the lungs The dust function can significantly enhance the ability of alveolar cells to expel toxic fine particles, and can effectively assist the human body in expelling PM2.5 particles and other harmful substances accumulated in the body.
For details, please refer to the Baidu Encyclopedia introduction of Tong Platycodon tea and Platycodon soup.
(4) Appropriate supplement of vitamin D
In winter, there is a lot of fog and less sunshine. Due to insufficient ultraviolet exposure, the production of vitamin D in the human body is insufficient, and some people will suffer from mental laziness and moodiness. If you feel depressed and other symptoms, you can supplement some vitamin D if necessary.
(5) Eat a light diet and drink more water
In foggy days, you should choose foods that are light, easy to digest and rich in vitamins, drink more water, and eat more fresh vegetables and fruits. Not only can it supplement various vitamins and inorganic salts, it can also moisten the lungs and remove dryness, eliminate phlegm and relieve cough, and strengthen the spleen and kidneys. Eat less irritating food and eat more pears, loquats, oranges, tangerines and other lung-clearing and phlegm-clearing foods.
(6) It is best not to go out or do morning exercises
Smoggy weather is a "health killer" for patients with cardiovascular diseases, especially the elderly with respiratory diseases and cardiovascular diseases. It is best not to go out on foggy days, and it is not advisable to do morning exercises, otherwise it may induce illness, or even a heart attack, which may be life-threatening. Experts point out that the reason why foggy days are "dangerous days" for patients with cardiovascular disease is because the air pressure is low when fogging, and the oxygen content in the air drops. People can easily feel chest tightness, and the morning is wet and cold
The mist can 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 diseases such as high blood pressure and cerebral hemorrhage. Therefore, people with cardiovascular disease, especially the elderly and infirm, should not go out on foggy days, let alone morning exercises on foggy days, to avoid danger.
