What diseases can smog cause? What diseases can smog cause?

Haze is an air pollution phenomenon! When you go out in foggy days, you must be well protected and wear an anti-fog mask. Otherwise, long-term inhalation of smog will easily lead to some diseases. Many people are confused. What diseases can smog cause? What diseases can smog cause? What diseases can smog cause? Let me answer them for you one by one!

What diseases can smog cause? 1. Upper respiratory tract infection: In foggy weather, a large number of harmful substances such as dust particles and smoke particles floating in the air will cause harm to human respiratory tract. Once inhaled by the human body, it will stimulate and destroy the respiratory mucosa, dry the nasal cavity and destroy the defense ability of the respiratory mucosa. Bacteria will enter the respiratory tract and easily cause upper respiratory tract infection. 2. Bronchial asthma: In smoggy weather, air pollution is heavier than usual, and there are often bacteria and viruses in the air, which can easily lead to the spread of infectious diseases and various diseases. In particular, air pollutants in cities are not easy to spread, 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 days, dust and smoke are floating in the air, and dust mites may also be suspended in the fog. Inhalation of these allergens by patients with bronchial asthma will stimulate the respiratory tract and cause asthma symptoms such as cough, sulking and poor breathing. 3. Lung cancer: Experts say that the incubation period of lung cancer ranges from several years to decades. Children with lung cancer at an early age are probably related to genetic factors and gene mutations. However, compared with adults, children's height determines that they are indeed more susceptible to automobile exhaust and road dust, which is recognized by the medical community. Because children's breathing zone is just close to the height of waste gas, at the same time, children's exposure per unit weight is higher than that of adults, which leads to their higher susceptibility, so they are more susceptible to pollution gases such as waste gas and smog. In addition, children's body organs are not fully developed, and the invasion of polluted gas causes more harm.

4. Conjunctivitis: According to experts, particulate matter attached to the cornea in foggy days may cause corneal conjunctivitis, or aggravate the condition of patients with keratitis and conjunctivitis. People also have the same situation, dry eyes, soreness, tingling, redness and allergies. 5, cardiovascular and cerebrovascular diseases: smog weather, low oxygen content in the air, will make the heart beat faster, making people feel chest tightness and shortness of breath. Especially the elderly. 6. Various bacterial diseases: Because of the foggy weather, the sun did not shine on the earth, or the sun was weak. This will cause bacteria, viruses and microorganisms on the ground to multiply rapidly, causing diseases such as allergies. 7. Children's rickets: In addition to the increase in the incidence of respiratory diseases and the rate of hospitalization, smog weather will also have some indirect effects on human health. Haze will weaken ultraviolet radiation. If smog often occurs, 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.

What diseases can smog cause 1. It may induce cardiovascular diseases:

Recently, the number of people who go to the hospital to see respiratory diseases has soared, especially those "old patients" with chronic respiratory diseases. A significant impact of smog on human health is that it can cause or aggravate respiratory diseases. Jiang, the chief physician of the Women and Children Medical Center, said that the recent patients were mainly acute respiratory infection, bronchitis and asthma, and the proportion of asthma in children doubled. At the same time, cloudy days may also induce cardiovascular diseases. It is suggested that if the elderly and children feel unwell in foggy days, especially those with respiratory tract or cardiovascular history, they should go to the hospital for examination and treatment immediately, and try to exercise indoors in foggy days.

2. Be careful not to get conjunctivitis:

The continuous smog days made many pedestrians wear masks. While protecting your mouth, have you neglected your eyes? The main components of smog are dust, sulfuric acid, nitric acid and other physical substances and chemical particles in the air, which are easy to cause irritation to the ocular mucosal system and lead to non-infectious conjunctivitis (chemically irritating conjunctivitis). As for conjunctivitis caused by smog, Professor Zhou said that it is quite difficult in the treatment process, so patients who live in smog areas for a long time should be reminded to pay enough attention. Experts reminded that after the smog weather returns, it is necessary to wash the skin in time and rinse the eyes with clean tap water to reduce the time for bacteria to attach; If your eyes are uncomfortable in foggy days, you must not buy eye drops at will, and you should seek medical advice in time.

3. It is easy to cause respiratory diseases:

According to physical examination experts, young people in smog weather often have symptoms of upper respiratory tract infection such as dry cough and sore throat, and allergic rhinitis also takes the opportunity to attack; Middle-aged people in their thirties and forties are mostly manifested as lung infection, pneumonia and bronchial asthma. Most elderly people show acute attack of chronic respiratory diseases, mainly chronic bronchitis and emphysema. The incidence of allergic respiratory diseases in foggy days is mainly because the respiratory resistance of patients with asthma and allergic rhinitis is weaker than that of ordinary people. Suspended substances such as dust, smoke and dust mites floating in the air will become allergens. Patients with bronchial asthma will irritate the respiratory tract and have symptoms such as coughing, sneezing, chest tightness and poor breathing.

Self-protection in severe fog 1. Stay at home in foggy days and go out less: Going out less in foggy days is the most effective way to protect yourself, especially for cardiovascular and cerebrovascular diseases, respiratory diseases, children and the elderly. Because pollutants such as industrial waste in smog, automobile exhaust, bacteria and viruses in the air will aggravate the condition of respiratory and cardiovascular diseases. In particular, children's respiratory tract, trachea and bronchial mucosa are tender and the number of alveoli is small, which is easy to lead to respiratory diseases. Because of poor physical resistance, the elderly are prone to lung infection and other problems. 2. Avoid outdoor sports in foggy days: Avoid outdoor sports in foggy days. It is easy to inhale dust particles in the air during exercise, especially not in the morning and evening, because the temperature is low in the morning and evening, which is the peak of smog. It is best to choose indoor exercise in foggy days. If you must go out for exercise, you can choose when the sun is shining at noon, wait for the pollution particles to rise to the sky, go for a walk in the park, and play Tai Chi. And be careful not to stay outdoors with severe smog for a long time.

3. Wash your face and mouth and nose frequently in foggy days: In foggy days, air particles have certain adhesiveness, which will be adsorbed on skin and hair, which will harm human health. Therefore, after going out, you should do a good job in time, wash your face, hands, gargle, clear your nose and remove smog particles with warm water. Pay attention to the use of facial cleanser when washing your face, and choose alkaline soap when washing your hands, because alkaline soap has a strong cleaning effect and is more conducive to washing off particles. 4. Don't ride a bike when you go out in foggy days: Because your body needs oxygen when riding a bike, it will inhale more air. In foggy days, the air pollution is serious. The faster you ride a bike, the more chemical components you inhale. Therefore, sometimes when going out, it is best not to ride bicycles and electric cars, but to take other means of transportation to reduce outdoor exposure.

5. Wear a mask when going out in foggy days: Wearing a mask in foggy days is essential. When you need to go out, you must wear a mask with good filtering material and good facial fitting effect, such as a professional N95 mask, which can help filter out the polluted particles in the air and effectively prevent harmful particles in the smog from entering the human body through breathing. In addition, pay attention to the mask to be cleaned every day. 6. Reasonable use of purifiers in foggy days: Many people will choose indoor air purifiers in foggy days. They should choose an air purifier that can remove particles, sterilize and disinfect, and pay attention to changing the filter regularly when using it. Keep a certain distance from the wall and keep the air circulating.

7. Pay attention to clearing the lung and protecting the lung in foggy days: The damage to the lungs in foggy days is enormous. If prevention is not strengthened, it is easy to induce diseases of the bronchus, respiratory tract and lungs. Therefore, to protect yourself in foggy days, we must pay attention to clearing away lung heat and protecting lung. You can eat some foods that clear and moisten the lungs, such as lily, lotus seed, tremella, pear, water chestnut, etc., and keep some pure heart at home. 8. Drink more boiled water in foggy days: Drink more boiled water in foggy days, because drinking water can help us enhance the vitality of respiratory cilia, improve self-purification ability and reduce the harm of smog particles to the respiratory tract. Therefore, drink more boiled water at ordinary times to discharge excess garbage and toxins from the body.
