1. the difference between fog and haze
smog, fog and haze are collectively referred to. 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 near-surface air, which mostly appears in autumn and winter and is the product of water vapor condensation (or condensation) in the near-surface air. The existence of fog will reduce the air transparency and worsen the visibility. If the' horizontal visibility of the target is reduced to less than 1 meters, the weather phenomenon of water vapor condensation (or condensation) suspended in the air near the ground is called fog; The phenomenon that the horizontal visibility of the target is 1-1 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 reach 1%. Because the light scattered by fog composed of liquid water or ice crystals has a great 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 the vision and worsen the visibility. If the horizontal visibility is less than 1, meters, the visual range obstacle caused by this non-aquatic aerosol system is called haze or haze.
2. Haze-related diseases
(1) Upper respiratory tract infection
Persistent smog weather hangs over more than 1 provinces in China. In smog weather, a large number of harmful substances such as dust particles and smoke particles float in the air, which will do harm to the human respiratory tract. Once inhaled by the human body, a large number of particles, dust, pollutants and viruses float in the air, which will stimulate and destroy the respiratory mucosa, make the nasal cavity dry and destroy the respiratory mucosa.
(2) Bronchial asthma
In haze weather, the air pollution is heavier than usual, and bacteria and viruses often appear in the air, which may easily lead to the spread of infectious diseases and various diseases. Especially, air pollutants in cities are not easy to diffuse, which aggravates the toxicity of sulfur dioxide, carbon monoxide, nitrogen oxides and other substances and will seriously threaten people's lives and health. In foggy weather, dust and smoke are floating in the air, and dust mites may also be suspended in the fog. Patients with bronchial asthma inhale these allergens, which will stimulate the respiratory tract and cause asthma symptoms such as cough, sulking and poor breathing.
(3) Lung Cancer
Professor Kan Haidong from Fudan University School of Public Health said that the incubation period of lung cancer ranges from several years to decades, and the onset of lung cancer in young children is probably related to genetic factors and gene mutations. However, compared with adults, children's height determines that they are really more affected by automobile exhaust and road dust, which is recognized by the medical profession. Because children's breathing zone is just near the height of exhaust gas, at the same time, children's respiratory exposure per unit weight is higher than that of adults, which leads to their higher susceptibility, so they are more affected by polluted gases such as exhaust gas and smog. In addition, children's body organs are not fully developed, and the damage caused by the invasion of polluted gas is even greater.
(4) Conjunctivitis
According to experts, particles in the air attached to the cornea in foggy days may cause keratitis and conjunctivitis, or aggravate the condition of patients with keratitis and conjunctivitis. The number of patients with keratitis and conjunctivitis < P > has increased significantly, including the elderly and children, as well as office workers who are facing the computer all day. People have the same situation: dry eyes, soreness, tingling, redness and allergies.
(5) Children's rickets
The preliminary study found that haze weather not only caused an increase in the incidence/hospitalization rate of respiratory diseases, but also had some indirect effects on human health. Haze will weaken ultraviolet radiation. If haze occurs frequently, it will affect the synthesis of vitamin D in human body, lead to a high incidence of rickets in children, and enhance the activity of infectious bacteria in the air.
3. Self-prevention in foggy weather
(1) Less window opening in foggy weather
It is not recommended to open the window for ventilation in the morning and evening in foggy weather, so it is better to wait until the sun comes out.
(2) Wear a mask when going out
If you go out, you can wear a mask
, which can effectively prevent dust particles from entering the body. Cotton masks are the best because some people are allergic to non-woven fabrics, while cotton masks are generally not allergic and easy to clean. When you come back from going out, you should wash your face and bare skin immediately.
(3) Drink more Tongplatycodon grandiflorum tea, Tongshen tea, Tongplatycodon grandiflorum granules, orange stem soup, etc.
Tongplatycodon grandiflorum tea has the function of clearing away fire and filtering lung dust, can significantly enhance the ability of alveolar cells to discharge toxic fine particles, and can effectively assist the human body to discharge PM2.5 particles and other harmful substances accumulated in the body. For details, please refer to Baidu Encyclopedia of Tongplatycodon grandiflorum tea and orange stem soup.
(4) Appropriate vitamin D supplementation
In winter, there is much fog and little sunshine. Due to insufficient ultraviolet radiation, vitamin D production in the human body is insufficient, and some people may feel lazy and depressed. If necessary, some vitamin D can be supplemented.
(5) Eat light and drink plenty of water
In foggy days, you 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 the roles of moistening the lungs, eliminating phlegm and relieving cough, strengthening the spleen and tonifying the kidney. Eat less irritating food, and eat more foods such as pears, loquats, oranges, oranges, etc.
(6), it is best not to go out or do morning exercises
Smoggy weather is a "health killer" for patients with cardiovascular diseases, especially for the elderly with respiratory diseases and cardiovascular diseases. It is best not to go out in foggy weather, let alone do morning exercises, otherwise it may induce illness, even heart attack, and cause life-threatening. Experts pointed out that foggy days are "dangerous days" for patients with cardiovascular diseases because the air pressure is low when foggy, and the oxygen content in the air drops, which makes people feel chest tightness easily. The humid and cold fog in the morning can also cause cold stimulation, which can easily lead to vasospasm, blood pressure fluctuation and increased heart load. At the same time, some pathogens in fog can cause headaches and even induce diseases such as hypertension and cerebral hemorrhage. Therefore, people with cardiovascular diseases, especially the elderly and infirm, should not go out in foggy days, let alone do morning exercises in foggy days to avoid danger.
