What are the hazards of sandstorms to humans

The weather nowadays is changeable. Sandstorms are one of the worse weather types, which can shock us greatly because there will be hundreds of meters of sand and dust rolling around. In such bad weather, it is easy for us to suffer from some respiratory diseases. Therefore, we must do a good job of health care in our lives. So what are the hazards of sandstorms to humans?

The combination of dust and wind storms leads to sandstorms. The northwest region of the mainland is arid and desert-rich. Once strong cold air passes through, strong winds are generated close to the surface, which can easily cause sandstorms. This is the special condition that causes sandstorms, so the northern region of the mainland is a high-incidence area of ​​sandstorms. The sandstorms originate from the Gobi Desert in eastern Xinjiang, the northern plateau and the Hangai Basin in Mongolia. It usually occurs in spring because the soil in the desert thaws and the surface is softer. In addition, the temperature difference between morning and evening is very large, which creates strong winds and carries sand and dust southward. Affected by the westerly circulation, the sandstorm advanced eastward along the wind erosion desertification area on the northern slope of Yinshan Mountain, continuing to stir up large amounts of sand and dust along the way. According to US satellite photos, sandstorms on the mainland can "invade" all the way from North China to the west coast of the United States within seven days.

Because sandstorms can easily cause respiratory diseases, the Environmental Protection Agency set up an observation station in Matsu for early warning two years ago. Generally speaking, healthy people do not need to worry too much about sandstorms, but if the concentration of suspended particles in the air is too high, normal people will also feel irritated and unbearable, such as coughing, dry eyes or itchy throat, etc. When the PSI value exceeds 200 (in cities with serious air pollution, the suspended particles in the air are usually between 100-200), even healthy people should reduce outdoor activities.

How to prevent respiratory diseases?

In sandstorm weather, the elderly and children are more likely to develop respiratory diseases, because this group of people have relatively weak constitutions and poor resistance. They usually inhale particles in the air into our bodies, causing respiratory diseases, and sometimes triggering recurrence of old diseases. Therefore, this group of people should do a good job of health care in time, and should strengthen the balance of nutrition in diet to improve our body's resistance. We should eat more eggs, fish, and soy products such as the common ones, fungus, loofah, walnuts, honey, kelp and other foods, which have a good effect on our body's expectoration and asthma, moistening the lungs and relieving coughs. In daily care, if you encounter a sandstorm, you should close the doors and windows, reduce outdoor exercise, disinfect, clean and purify the air in your home, and open the windows to keep the air flow unobstructed for one to two hours a day. If you have to go outdoors for exercise, you should bring various protective measures to prevent sand and dust from being inhaled into your body. However, in sandstorm weather, if you find that you have adverse symptoms, you should seek medical treatment in time to avoid delaying the disease.

The above is an introduction to the harm of sandstorms to humans. We should do some disease prevention work in our daily lives. When there are some bad weather conditions, it is best to wear a mask when going out to prevent some bad substances from being inhaled into the human body, which will have a certain impact on the body.
