What kind of harm will dusty weather bring to people?

Whenever sandstorms hit northern cities, the number of eye patients in otolaryngology department of local hospitals will increase sharply. Sandstorms can directly cause eye pain and tears. If you don't clean the dust, or rub your eyes with your hands, it will cause bacterial or viral eye diseases. Therefore, when there is sand-blowing weather, wear dust-proof glasses when going out; If dust gets into your eyes, don't rub it with your hands. Wipe gently with a clean wet towel. If not, go to an eye hospital.

Sandstorms can also cause respiratory diseases. Poor air quality causes some people with unhealthy respiratory tract to have symptoms of dry cough, expectoration and hemoptysis, and may also be accompanied by high fever. In addition, the strong wind makes the surface evaporate strongly, driving away a lot of water vapor, greatly reducing the humidity in the air, chapping people, weakening the elasticity of nasal mucosa due to drying, prone to micro-cracks, reducing the disease prevention function, and germs in the air will take advantage of it.

In terms of physical attributes, sandstorms also have a great negative impact on people's mental health. First of all, when sandstorms appear, the collision and friction noise between air and dust will make people feel uncomfortable; Especially the low audio frequency of strong wind can directly affect the nervous system of human body, causing headache, nausea and irritability. Secondly, strong winds and dust often seriously reduce the "vitamins" in the air, that is, negative oxygen ions, leading to changes in some people who are sensitive to weather changes, making people feel nervous and tired. Thirdly, when the sandstorm strikes, the visibility is low and the light is dark, which limits people's vision and gives people a feeling of depression and fear.
