Sandstorm is the most harmful to human respiratory system. A large number of suspended particles in sandstorms, especially fine particles below two microns, are most easily inhaled into the deep respiratory tract. With the increase of dust particles inhaled into nasal cavity, once it exceeds the clearance ability of nasal cavity and lung itself, it will lead to lung and pleural lesions. These dust particles will be deposited in alveoli through the respiratory tract, and then form silicon nodules, leading to "interstitial" lung diseases such as chronic respiratory inflammation and emphysema. Under normal circumstances, people's nasal cavity, lungs and other organs have a certain filtering effect on dust, but the dust storm, a disastrous weather phenomenon, brings too much and too dense fine dust, which is very likely to make patients with respiratory diseases relapse or aggravate their condition. Strong wind makes the surface evaporate strongly, driving away a lot of water vapor, which greatly reduces the humidity in the air, weakens the elasticity of nasal mucosa due to dryness, and is prone to tiny cracks, thus reducing the disease prevention function, and germs in the air will take advantage of it. In the season of frequent sandstorms, we should pay attention to the weather forecast in order to do a good job of protection in advance. When it is windy, close the doors and windows in time to minimize going out. If you have to be outdoors because of professional needs, you must wear a mask with dustproof and dust filtering functions to reduce the dust inhaled. But this simple protection can't stop fine particles with smaller particle size, so be sure to clean your nasal cavity carefully after you go home. When washing your face every morning and evening, you can gently inhale clean water through your nose, and then spit it out to keep your nasal cavity clean, which can not only clean the nasal cavity and prevent particles from entering the lungs, but also stimulate acupuncture points, regulate physiological functions and protect your nose.

If conditions permit, you can use a humidifier indoors, or sprinkle water and mop the floor with a wet mop. It is not suitable for outdoor sports or leisure activities at this time. When pedestrians go out, it is best to wear a mask or scarf to cover their heads, which can reduce the damage of sandstorm to respiratory tract and glasses. Pedestrians should avoid canals and reservoirs to avoid drowning accidents due to sight and wind. Pedestrians should also stay away from high-voltage wires, construction sites, billboards and ancient trees. , and try to be in the strong leeward without falling objects. Reading "San Zi Jing" is dusty, harmful to health and not sick. Dr. Zhao from the Department of Respiratory Medicine of the Fourth Hospital of Jilin University said that dusty weather has a great impact on people's health. Inhalation of respiratory dust can lead to asthma attack, rhinitis, tracheitis and allergic symptoms; In addition, dusty weather is also very harmful to eyes and skin. If you don't pay attention, it will cause problems such as redness, inflammation and large pores in the skin. Therefore, how to protect our health in dusty weather is also a course. It's not difficult. If you don't believe me, take a look at the "Three Classics of Dust Prevention"-dirty air, itchy throat, eating fruit and drinking some soup. The doctor said that cleft lip and glutinous rice balls are most likely to appear in dusty weather. Doctors suggest that you can drink more porridge and soup, drink more water and eat more fruits in such weather, which can increase the water content of the body and accelerate the discharge of various metabolic wastes in the body. It is a good habit not to try to be brave and love sports in dusty days. However, when there is a sandstorm, outdoor sports should be avoided as much as possible, especially for the elderly and infirm. You should cancel morning exercise and exercise indoors instead. When the wind blows, the skin is dry, delicate and clean, and it is often maintained in dusty weather. The moisture on the surface of human skin is easily taken away by the wind, which makes the skin rough. Therefore, you should wash your face in time and apply hydrating skin care products after you go home. Dust-proof, prevent germs from gargling frequently and dredge nasal cavity. In dusty weather, not only the wind and sand are fooling around, but also germs will join in the fun. Therefore, it is best to take protective measures when going out, such as wearing a mask. In addition, after you come back from the outside, rinse your mouth with clear water and clean your nasal cavity to reduce the chance of bacterial infection. When sand enters your eyes, your eyes are easily injured. Don't rub your hands. It is especially important to protect your eyes with water. If dust is blown into eyes, it will cause corneal abrasion, conjunctival congestion, dry eyes and tears. It is best not to wear contact lenses, and try to wear ordinary frame glasses. Once the dust blows into your eyes, you can't rub it with dirty hands. Rinse with running water or drop a few eye drops as soon as possible to fight infection. I can't see very far. I drive slowly in the yellow sky, avoiding the edge.

What are the hazards of sandstorms?

Hazards caused by sandstorms: 1. Environmental pollution: When sandstorms occur, there are dust and floating dust wrapped in strong winds everywhere, and the number of people passing through areas with frequent diseases such as air turbidity, choking nose and eyes, and respiratory diseases increases. For example,1A serious sandstorm occurred in Jinchang on May 5, 993. The dust content in outdoor air is 10 16 mm/cm3, and the dust content in indoor air is 80 mm/cm3, which is 40 times higher than the national standard for dust content in living quarters. 2. Production and life are affected. A lot of dust carried by sandstorm weather blocked the sun, and the weather was gloomy, which led to the decrease of solar radiation. A few hours to ten hours of poor visibility can easily make people feel depressed and reduce the efficiency of work and study. In light cases, a large number of livestock can be infected with respiratory and gastrointestinal diseases, and in severe cases, a large number of "spring-deficient" livestock will die, and fertile soil, seeds and seedlings in farmland will be scraped away. Sandstorm will also aggravate the wind erosion and desertification of the surface soil, cover thick dust on the leaves of plants, affect normal photosynthesis and cause crop yield reduction. Sandstorms also caused the temperature to drop sharply. The sky is like a parasol, and the ground becomes dark and cold in the shadow. 3. Loss of life and property 65,438+0,993 On May 5, 2003, severe sandstorms occurred in Jinchang, Wuwei, Minqin, Baiyin and other places in Gansu Province, affecting 2,535,500 mu of farmland, losing 42,800 trees, causing direct economic losses of 236 million yuan, 85 people died and 65,438 people were seriously injured. On April 12, 2000, serious sandstorms occurred in Yongchang, Jinchang, Wuwei and Minqin. According to incomplete statistics, the direct economic losses in Jinchang and Wuwei alone amounted to15.34 million yuan. Extended data:

Sandstorm is the most harmful to human respiratory system. A large number of suspended particles, especially fine particles, in floating dust are most easily inhaled into the deep respiratory tract. Strong wind makes the surface evaporate strongly, driving away a lot of water vapor, which greatly reduces the humidity in the air, weakens the elasticity of nasal mucosa due to dryness, and is prone to tiny cracks, thus reducing the disease prevention function, and germs in the air will take advantage of it. With the increase of dust particles inhaled into nasal cavity, once it exceeds the clearance ability of nasal cavity and lung itself, it will lead to lung and pleural lesions, and these dust particles will be deposited in alveoli through respiratory tract, causing lung diseases such as chronic respiratory inflammation and emphysema. It is also easy for people with respiratory diseases to relapse or aggravate. Sandstorm weather should first prevent dust from entering the body, and do the following protective work: 1, minimize travel, and close doors and windows indoors to avoid dust exposure. 2. When traveling, pay attention to wearing a mask with dustproof and dust filtering functions, and use it correctly to reduce the dust inhaled into the body. In addition, you can choose windproof glasses to protect your eyes. When choosing them, we should pay attention to the good transparency of glasses, which will not hinder the normal observation of road conditions. 3. Pedestrians should not walk or stay under billboards or trees. Don't drive in a hurry, turn on the width lights, fog lights and taillights, slow down the speed, and honk more to warn the front, rear, left and right vehicles. Some small cars, try to reduce parallel driving to prevent being blown off the road by strong winds. Pay attention to avoid big trucks, away from balconies and billboards, and use internal circulation mode for air conditioning. Once the dust blows into your eyes, you can't rub it with dirty hands. Wash or drop a few drops of eye drops with running water as soon as possible, which can not only keep your eyes moist, but also help dust flow out and play an anti-infection role. 5. Go back to your home and rinse your mouth with clear water, and carefully clean your nasal cavity. You can gently inhale clean water through your nose, and then spit it out to keep the nasal cavity clean. This can not only clean the nasal cavity and prevent particles from entering the lungs, but also stimulate acupuncture points, regulate physiological functions and protect your nose. Change clothes in time to keep your body clean and comfortable. Indoor dust should be cleaned in time and wiped with a wet rag to prevent dust from flying into the room and inhaling into the respiratory tract. 6, sandstorm weather is usually dry air, should pay attention to drink plenty of water, and strengthen skin moisturizing.
