Sand dust out and don't forget dust mask

Studies have shown that every year from late April to late May is a period of high dust storms in northern China. Just in the "51" that just passed, the weather in Jansang unceremoniously swept everyone's interest on the first day of the small holiday. “Do not want to go out” is the strongest feeling of many people in such a weather. There are also many people who feel irritated and depressed. Some patients with chronic diseases even have respiratory, cardiovascular and other discomforts. However, such weather is not over. How much does it affect people's physical and mental health, and where do we go about protecting ourselves? In this issue, the reporter’s multi-pronged division of the military has asked the experts to do a detailed analysis for everyone.

Do not carelessly, sand and dust will also break the emotions

Dr. Fang Jianqun, Director of Psychosomatic Medicine, General Hospital of Ningxia Medical University

Causes of gray days, with air smell of soil, hair, eyes, disturbing sand and dust in the nostrils ... This kind of weather affects people's health, but also undermined people's good mood. Fang Jianqun analyzed that the appearance of special weather could easily lead to hormonal disorders secreted by the human brain, induce mental disorders, anxiety, chronic fatigue syndrome, depression and other psychological diseases, as well as the condition of patients with mental illness and mental illness. Aggravated, unusually disturbed. Fang Jianqun analyzed that the sky is full of yellow sand and winds are screaming. It will make people feel disagreeable to the wind and sound. The dusty weather will also cause a sharp drop in temperature, causing people to feel depressed and fearful. At the same time, dust weather will reduce people's ability to respond, and frequent traffic accidents are also closely related to mood.

Measures must be taken to cultivate a variety of interests and hobbies, and to carry out a number of colorful indoor activities, so that even in the event of sand and dust, you can also live in indoor happy life. For outdoor workers, work hours should be minimized to avoid prolonged contact with dust. If the mental health problems in sand and dust weather are more serious, psychological counseling agencies should be promptly consulted. (Reporter Jiang Yu Li Dongmei wrote)

Remember, respiratory diseases are "blowing"

Dr. Cui Liping, MD, Department of Respiratory and Critical Medicine, General Hospital of Ningxia Medical University

In dusty weather, the concentrations of total suspended particles and inhalable particles in the atmosphere increase. These dust particles enter human airways along with human breath. Especially particles with a diameter of 0.5-5 μm can enter the bronchi and bronchioles. The final settlement in the alveoli, resulting in a strong stimulating effect on the lung tissue, making people have shortness of breath, chest tightness, cough and other unwell reactions, causing acute and chronic respiratory diseases.

Countermeasures: “In the case of dusty weather, try to reduce the number of people out of doors and avoid contact with polluted air. People who must work outdoors must wear masks.” Cui Liping reminded the public that the impact of dusty weather on normal people was formed in a small amount, initially possible. There is no feeling of any discomfort, but human organs are pathologically consciously unknowingly. If they are in a contaminated air environment for a long time and do not take any protective measures, they may induce respiratory diseases for many years. Therefore, try to avoid going out in dusty weather. If you must go out, you must not take a deep breath and try to wear a professional dust mask.

Protected, sensitive skin is most injured

Dr. Zhu Xiangdong, Deputy Chief Physician, Department of Dermatology, Ningxia Academy of Traditional Chinese Medicine

The reason is that the spring weather is relatively dry, the surface of the skin's moisture can easily be taken away by the dust, which results in rough skin, large pores. When it encounters dusty weather, tiny dust, floating objects in the air carry some germs and viruses, and the pores are blocked when the skin contacts. If you do not remove it for a long time, it will cause acne, and people with allergies will also have red blood cells and pigmentation.

Measures of hydration, moisturizing, and cleansing are the primary lessons for protecting the skin from dusty weather. After returning home, apply warm water to wash your face and take a bath to keep your skin clean and hygienic. I wish Dongdong to remind everyone that people with allergic skin types should minimize their exposure to dusty weather. Remember to apply some lotion before you go out, and then wear masks, glasses, hats, shawls, and then go out after the "armed." If the skin and nose are allergic after returning home, you can take antihypersensitivity drugs such as loratadine

Carefully, middle-aged and elderly people are prone to cardiovascular and cerebrovascular diseases

Dialogue with Cardiology and Cardiology, General Hospital of Ningxia Medical University

Causes During dusty weather, the concentration of particles in the air will suddenly increase, adversely affecting health, and may even lead to the occurrence and worsening of various cardiovascular and cerebrovascular diseases such as heart disease, hypertension, coronary heart disease, angina pectoris, and cerebral infarction. Li Xi told reporters that dusty weather is often accompanied by cooling, combined with hot and cold spring weather, resulting in intense vascular contraction, blood pressure fluctuations, the elderly are sometimes difficult to adapt to, easily induced cardiovascular and cerebrovascular diseases.

Measures to remind the middle-aged and elderly people to encounter sandstorm weather, to minimize going out, to keep the diet light, to avoid large fluctuations in the mood, but also timely detection of blood pressure is normal, if the body appears unwell, must not be taken care of, to the hospital.

Did you know that before and after the May 1st, there were frequent dust storms?

According to meteorologists, sandstorms are likely to occur from late April to mid-May each year. Although the dust weather in the North has been significantly reduced in recent years, it can be prepared for preventive health care.

Studies have shown that, from late April to late May of each year, climate conditions in northern China where there is little or no rain and temperatures change can easily induce sandstorms and strong sandstorms. The source of sandstorms in the arid regions of China is experiencing an increase in surface temperature, and it is easy to form deep thermal convective boundary layers with a height of 3,000 to 4,000 meters. At this point, once there is a strong cold air transit, the power and heat conditions that induce strong sandstorms are extremely prone to occur.

Historical data shows that strong sandstorms in northern China are concentrated from late April to mid-May. In recent years, the frequency of dust weather in northern China has been significantly reduced, but this time period is undoubtedly the most prone to sandstorms, and is also a high dust storm period.
