What are the four diseases easily induced by dusty weather?

The abnormal weather with strong winds and dust makes many people feel unwell.

People should not take the weather changes lightly, and the elderly and children should be the key protection groups, because the resistance of the elderly and children is weaker than that of ordinary people, and some elderly people have already suffered from chronic bronchitis. If you don't pay attention to protection in windy and dusty days, the old disease will recur or cause other diseases. There are many kinds of diseases directly caused by abnormal weather, especially the direct contact parts such as eyes, nose, throat and skin. Among them, the damage of eyes, nose, throat, skin and other direct contact parts mainly shows irritation symptoms and allergic reactions, while the damage of lungs is more serious and extensive.

Dust hurts the lungs first.

When people encounter high-density dust without taking preventive measures, it will first cause various irritating symptoms, such as runny nose, tears, cough and expectoration, as well as systemic reactions such as shortness of breath, fatigue, fever and night sweats. These are mostly short-term symptoms, which are self-protection ways for the human body to remove foreign bodies, and the general injury will not last. But sometimes the reaction will be very serious, especially when exposed to high-density dust for the first time or suddenly, which can be manifested as sudden shortness of breath, chest pain, chest tightness, headache, dizziness and so on. Especially patients with asthma, chronic lung disease and heart disease. Therefore, people with respiratory diseases and weak resistance had better not go out in windy and dusty days.

Particulate matter entering the lungs can lead to the decline of bronchial ventilation function and the loss of alveolar ventilation function, which can further cause many hazards. Living in an environment polluted by particulate matter for a long time will obviously inhibit the immune function, leading to the decline of the resistance of the respiratory system to infection and the increase of the prevalence of respiratory diseases.

American scientists have also found that there is a correlation between fine dust particles and mortality from lung disease and heart disease. Studies in Australia show that sandstorms may be closely related to the high incidence of asthma in that country. Our country has also made a survey. Residents who have lived in some areas of Xinjiang for more than 30 years account for a certain proportion of non-occupational pneumoconiosis, and it is closely related to their living in a dusty environment, so this disease is called aeolian pneumoconiosis.

Dust weather to minimize going out, it is recommended to wear masks when you have to travel.

Nasopharyngitis looking for office workers

It is understood that the number of outpatients in the otolaryngology department of China-Japan Friendship Hospital has increased by more than 20% in one week. Yang Dazhang, chief physician of the Department of Otolaryngology, said that the number of patients with allergic rhinitis, acute rhinitis, pharyngitis and asthma increased significantly, and most of them were office workers.

Yang Dazhang of China-Japan Friendship Hospital said that in spring, the temperature is getting warmer and bacteria are becoming very active. If there is dusty weather, many sundries and germs will enter the body with breathing, which will stimulate the human body to have symptoms such as runny nose, itchy nose and continuous sneezing. When the sandstorm is too strong, the dust will directly invade the throat along the nasal cavity and oral cavity, and may even cause otitis media. He suggested that everyone wear masks, scarves or hats when they go out, pay attention to keep warm, and at the same time, because there are more patients with respiratory diseases recently, they should go to crowded places less to avoid cross-infection of diseases.

Su Nan, deputy director of the Respiratory Department of China-Japan Friendship Hospital, reminded everyone that under normal circumstances, people's nasal cavity has a certain filtering effect on dust, but the fine dust brought by dusty weather is too much and too dense, which is easy to make people with respiratory tract and allergic history relapse or aggravate. Even people who have no history of respiratory tract are prone to cough, asthma and other discomfort symptoms when inhaling a lot of dust. For the elderly and infirm, respiratory diseases may become an important cause of pneumonia and cor pulmonale, so we must not treat them lightly.

"Invisible" people beware of conjunctivitis

The change of temperature and the decline of air quality make people easy to catch a cold, which leads to viral conjunctivitis and viral keratitis. At this time, the eye environment is very fragile.

Short-sighted people try to wear ordinary glasses in dusty weather. On the one hand, glasses play a protective role to prevent dust from entering the eyes; On the other hand, once the dust particles enter the eyes, the tears secreted by the lacrimal gland can also wash away the particles in time. Contact lenses are relatively fixed on the surface of the eyeball when worn. Dust accidentally enters the eyes and easily adheres to contact lenses, leading to the growth of germs. If you often wear contact lenses and do not pay attention to eye hygiene, it is easy to aggravate inflammation.

Chen Shu, chief physician of ophthalmology department of China-Japan Friendship Hospital, reminded that when dust and foreign objects enter the eyes, it is forbidden to rub the eyes by hand, which may easily cause injury to the eyes, pain, blurred vision and even keratitis in severe cases. When the wind-blown sand enters the eyes, it should be properly handled in the lee. Some dust can flow out with tears, so blink your eyes or lift your eyelids and shake them gently to increase the secretion of tears. Be sure to go to the hospital in time if necessary.

Fight allergic dermatitis

Wang Chen, chief physician of dermatology department of China-Japan Friendship Hospital, thinks that the wind is dry in spring, and the moisture on the skin surface is easily lost, which leads to rough, red and even chapped skin on the face and hands. After a long time, it may also cause bacterial infection. After all kinds of dust and debris enter the pores, if they are not removed in time, it is easy to appear acne, acne and itchy skin. And people with allergies are also prone to all kinds of allergic dermatitis and rashes.

Wang Chen suggested that protective measures should be taken when going out for activities or work, such as wearing masks or scarves. After returning indoors, wash your hands and face often to keep your skin clean. Also pay attention to properly rubbing some skin care products with high moisturizing degree and gentleness to avoid chapped skin injury. In addition, for women who often use cosmetics, it is best not to wear heavy makeup when going out, because dust and pollutants in the air are easy to mix with cosmetics, resulting in chemical reactions and aggravating skin irritation. Once the facial skin is red, swollen, itchy and rash, patients should not blindly take medicine or take medicine, and should go to the hospital to consult a dermatologist.

According to medical experts, early spring is the season of allergic dermatitis. Eating seafood allergy, food poisoning and taking the wrong medicine can all cause local skin allergy.
