Why did the dusty weather in Beijing also lead to the appearance of the blue sun?

I think the recent dusty weather has troubled many netizens. Shashi has appeared in most parts of China, which has seriously affected people's travel and respiratory tract. When there is dusty weather, the blue sun appears in the sky, which aroused the curiosity of netizens. This spectacle is mainly due to the scattering and absorption of red light with longer wavelength by particles in dust, which leads to the reduction of red light and makes the sun look blue!

Severe dusty weather has a very serious impact on people's travel, and it may also make it more difficult for some patients with rhinitis and some patients with respiratory problems to travel. Artificial snowfall has also been carried out in some areas of China to prevent the harm of dusty weather to people's travel. This reduces a lot of yellow sand floating in the air, effectively reduces floating dust and facilitates people's travel!

First, large-scale ups and downs in China have affected travel. It can be said that this dusty weather has attracted the attention of netizens, because the cities and regions affected by this dusty weather are very large, and almost all areas in China have been affected by this dusty weather. The scene we can see is full of yellow sand, and the substances floating in the air are also very harmful to the human body. Even some schools have decided to suspend classes.

The reason why the sandstorm weather in China is so serious is mainly because the sandstorm weather in Mongolia has spread to China. The sandstorm weather in Mongolia is extremely harmful, resulting in ten deaths and even many people missing. This also makes tens of thousands of livestock still missing and some houses destroyed, which can be said to be extremely harmful to Mongolia!

Some yellow sand floating in the air is also harmful to the human body from a long distance, so many primary and secondary school students have also suspended classes, and a large number of people will wear masks when they go out to protect themselves!

Second, take protective measures in dusty weather. Dust weather is more harmful to the elderly, pregnant children and people with respiratory diseases and cardiovascular diseases, because some people who are sensitive to particulate matter in dust weather are likely to be accompanied by chronic cough and shortness of breath and chest tightness. If this happens, they should seek medical treatment in time, and people who are outdoors should also take care of themselves. For example, some sanitation workers and construction workers should wear masks to protect themselves!

In dusty weather, first of all, if you need to go out, you must wear a mask to prevent some dust and floating dust in the air from causing certain harm to the human body. Secondly, you can wear goggles, so that dust in the air cannot enter people's eyes. Secondly, if your eyes are uncomfortable, you can drop some eye drops. Also, you can wear a hat when you go out to protect your face, skin and vulnerable places. When you get home, you should wash your face and brush your teeth in time, and you can take a shower if you have the conditions.

Dust weather is harmful to human body. If this happens, people's skin may be dry and have cleft lip. In case of dry and itchy throat, drink plenty of water and take some vitamins to reduce the harm of floating dust to human body!
