If you are a worker, you must have a sense of self-protection, wear it yourself, mobilize workers to wear it, and put forward requirements to the factory in order to improve the working environment and strengthen labor protection measures.
If you are an office worker, you should not only appeal for workers to strengthen labor protection and improve production conditions, but also strengthen ventilation in the office and wear a mask when the dust is serious.
Food can only be eaten in the stomach, which can't stop air pollution. Even a little effect is minimal. Just like Chinese medicine says persimmon moistens the lungs, but it can't cure silicosis.
Expedient measure: Sprinkle more water on the ground to keep the air moist. Gently stuffing two balls of cotton wool into your nostrils can also stop the dust. I used to be allergic to my nose, and I kept sneezing when there was dust in the air. At that time, I often stuffed two cotton balls in my nostrils.
Note: the nostril cotton ball is not too deep, so be careful not to take it out.
