What harm does sandstorm do to human body?

Yesterday, Shenyang people spent a day in foggy sky and foggy ground. Covered with a yellow filter, it looks lovely everywhere. People, rubbing around with broken steps. The car was driving with its headlights on.

The reporter interviewed an old man: "Grandpa, do you think that dusty days have any impact on our lives?" Grandpa said: "First of all, it has an impact on the eyes. Take a closer look. I am your aunt. "

According to experts, in the past ten years, the average number of sandstorms in China 1 month to March was four. Among them, the frequency of strong sandstorms is less than once.

But this year, Tokar is very noisy. 1-In March, there were six sandstorms in the northern part of our province. Both were strong sandstorms, the most in the last fifteen years.

Dust storms cause air turbidity, which is harmful to human respiratory tract, especially to patients with cardiovascular, cardiopulmonary, tracheal and laryngeal diseases.

Sandstorms can also cause soil erosion and hardening of rural crops. The leaves of crops and plants are covered with dust, which affects normal photosynthesis and water absorption and leads to crop failure.

Dust covers the sun, and tiny particles in the air are sucked into the nostrils and lungs. Many susceptible people have a feeling that if there is a sandstorm for a long time, that person will feel great discomfort.

1990, I lived in Kashgar, Xinjiang for half a year. Because I live in the desert and have experienced the scene of sandstorm personally, I am very aware of the harm of sandstorm to human body. The harm of sandstorm to human body mainly includes the following aspects. First, the human body will seriously damage the respiratory organs because of inhaling a lot of dust, and it is easy to suffer from various types of respiratory diseases. Second, a lot of dust is suspended in the air, which forms a foggy day, which affects people's eyesight and can't see things in the distance clearly. Because the air contains a lot of dust, it will damage people's eyes for a long time. Thirdly, the air is very dry because of the harm of sandstorm. If people live in dry air for a long time, the human body will have chapped lips and bleeding, and the skin will be very rough and chapped. These are my personal experiences in the desert.

Sandstorm [covering your face] It's hard to breathe at the thought of yellow sand all over the sky.

It's better for us Cantonese. Although the air is humid in spring, at least there is no dusty weather.
