What kind of harm will sand and dust weather bring to people?
Whenever sandstorms hit northern cities, the number of patients with eye diseases in the ENT department of local hospitals will increase sharply. Sandstorms can directly cause eye pain and tearing. If the dust is not removed or the eyes are rubbed with hands, bacterial or viral eye diseases can occur. Therefore, when there is sand blowing, you should wear dust-proof glasses when going out; if sand and dust enter your eyes, do not rub them with your hands. You can wipe them gently with a clean wet towel. If there is no effect, you should go to an eye hospital for treatment.
Sandstorms can also cause respiratory diseases. Poor air quality causes some people with unhealthy respiratory tracts to develop symptoms of dry cough, sputum, and hemoptysis, which may also be accompanied by high fever. In addition, strong winds cause the surface to evaporate strongly, driving away a large amount of water vapor. The humidity in the air is greatly reduced, causing dry lips and cracked lips. The elasticity of the nasal mucosa is weakened due to dryness, and micro cracks are prone to appear. The disease prevention function is subsequently reduced, and the germs in the air are 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 a sandstorm occurs, the collision and friction noise of air and sand will make people feel uncomfortable; especially the low audio frequency of strong winds can directly affect the human nervous system, causing headaches, nausea, and irritability. Secondly, strong winds and dust often severely reduce the "vitamins" or negative oxygen ions in the air, causing changes in the bodies of some people who are sensitive to weather changes, making people feel nervous and fatigued. Third, when a sandstorm strikes, the visibility is low and the light is dark, which limits people's vision and creates a sense of depression and fear.
