What's with the dusty weather?

Soil and sand grains on bare ground can be carried into the air by wind and turbulence, and carried to non-bare ground by airflow. In arid and desert areas, dusty weather will occur due to strong winds and strong turbulence, and dust particles will be carried to high altitude and transported to far places with high-altitude airflow. In the dust source, dust storm walls tens of meters high can be formed, which makes the atmosphere in some places have very high dust particle concentration.

The harm degree of floating dust mainly depends on the size of particles and the time of floating dust influence: particles larger than 10 micron can almost be captured by nasal cavity and throat. Particles below 10 micron can be directly driven into organs and tissues such as eyes, nose, throat and skin, and deposited in alveoli through respiratory tract.

If there is floating dust weather for a long time, once the dust particles in the lungs exceed the clearance ability of the lungs themselves, they will be deposited in the chest cavity, leading to lung and pleural lesions, leading to bronchitis, pneumonia, emphysema and other diseases. In dusty weather, people's eyes, nose, throat, skin and other direct contact parts will be damaged to a certain extent, mainly manifested as runny nose, tears, cough, expectoration, allergic reactions and other irritating symptoms, which will seriously lead to skin inflammation and conjunctivitis.

Protection guide

When there is dusty weather, you should try to reduce going out and close the doors and windows at home in time, especially the patients with chronic bronchitis and the elderly and children with relatively weak resistance. If you don't pay attention to protection in dusty days, it will recur or cause other diseases.

If you go out, it is best to use dust masks and glasses as protection, which can effectively block the stimulation of sandstorms to the respiratory tract and reduce or prevent dust from entering the respiratory tract and lung organs.

When people go home, they can rinse their mouths with clear water, clean their nasal cavity, reduce the chance of infection, and drink more water to speed up the discharge of metabolic waste in their bodies.
