You smell the flowers in the sunny south, and I suck the sand in the strong wind in Beijing.

These two days, the sandstorm in the imperial city is huge and full of flavor. Look at this day.

Tadpole Jun, for the health of friends, today's "recommended pavilion" column is suspended.

After all, going out is too expensive, which not only affects your external image, but also affects your menu:)

However, spit spit, such a serious meteorological disaster, you still have to learn to protect yourself. After all, eating dirt is not a long-term solution, and you have to go out sooner or later.

Dust weather refers to a weather phenomenon that strong winds roll up a lot of dust from the ground, which makes the air turbid and the horizontal visibility drops obviously.

Graphic self-watermarking

Sandstorm weather can be divided into three categories: floating dust, sand blowing and sandstorm.

Floating dust: sand or soil particles uniformly suspended in the atmosphere (mostly from other places, or left in the air after local sand blowing and sandstorm weather), so that the horizontal visibility is less than 10 km.

Sand blowing: the wind blows up the dust on the ground, making the air quite turbid, and the horizontal visibility is in the range of 1 km to1km.

Sandstorm: Strong wind blows up dust on the ground, making the air very turbid, and the horizontal visibility is less than 1 km. When the horizontal visibility is less than 500m, it is defined as a strong sandstorm.

When a sandstorm strikes, the lungs are most damaged.

Skin, nose, eyes, trachea and lungs are the first places to contact dust, so the victims are the most obvious.

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.

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.

Dust falling on the skin or eyes can also lead to blockage of sebaceous glands and sweat glands, leading to skin inflammation and conjunctivitis.

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.

Some studies have found that the immune function of primary school students who live in a particulate pollution environment for a long time will be significantly inhibited, resulting in a decline in the anti-infection ability of the respiratory system and an increase in 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.

Not long ago, a survey in China showed that non-occupational pneumoconiosis accounts for a certain proportion of residents who have lived in some areas of Xinjiang for more than 30 years, and it is closely related to their living in the environment of sandstorm and floating dust, so this disease is called aeolian pneumoconiosis.

In addition, a large number of dust particles diffuse in the air, which will scatter and absorb sunlight and reduce the intensity of ultraviolet rays on the ground, thus reducing the bactericidal and anti-rickets effects of ultraviolet rays.

Therefore, in areas with serious particulate pollution, the incidence of rickets in children is getting higher and higher, and the incidence of air-borne diseases such as tonsillitis and colds is also high.

Wear a mask and drink plenty of water to deal with sandstorms.

First of all, when there are chronic cough, expectoration or shortness of breath, paroxysmal dyspnea and chest pain, you should see a doctor as soon as possible, seek the help of professional medical staff and carry out corresponding treatment under their guidance.

Second, do personal protection.

When it is windy, you must reduce the chance of going out to contact with dust and close the doors and windows in time.

If outdoor activities are necessary due to professional needs, it is best to use dust-proof and dust-filtering masks to effectively reduce the dust inhaled.

Wet towels and gauze towels can be used to protect eyes, mouth and nose, but this simple protection can't stop fine particles with smaller particle size. Other protective measures include wearing appropriate glasses, dust-proof gloves, shoes and socks and clothes to protect eyes and skin, and washing hands and faces frequently (especially before eating).

Before the dust storm receded, construction workers, cleaners, etc. Outdoor work should be temporarily stopped.

Third, drink more water.

Graphical self-network

Sandstorm-prone season, dry weather, plus dust, the water on the skin surface is easy to lose, leading to rough skin, and dust is easy to block after entering pores. If it is not removed in time, it may cause acne, and people with allergies are prone to various allergic dermatitis and rashes.

Drinking plenty of water can replenish lost water in time and accelerate the discharge of various metabolic wastes in the body, which is very beneficial to skin care and general health.

It is worth mentioning that the elderly, infants and people with respiratory allergic diseases with poor physical resistance are "fragile". In the sandstorm season, we should pay more attention to health care and stay away from dust as much as possible.

Once you find obvious discomfort, you should go to the hospital immediately.

How to deal with sandstorms?

1. Prevention in advance

Prevention is better than cure. In windy, dry and dusty weather, bacteria, viruses, mycoplasma and other microorganisms are active frequently, which is beneficial to spread and easily induces pharyngitis, nosebleeds, dry eye, keratitis, tracheitis and asthma.

Usually delicious with throat lozenges to keep your throat cool and comfortable; Drop eye drops several times to avoid dry eyes; Ten thousand first-class nosebleeds, you can often drop a few drops of drying oil around the nostrils to keep the nasal cavity moist and prevent capillary rupture and bleeding.

2. Drink more water and eat more fruits.

Dry dusty weather is prone to cleft lip, dry throat and snuff. , that is, what the people call getting angry. Lack of water can also cause difficulty in defecation, causing hemorrhoids, anal fissure and bloody stool.

Drink more porridge, soup, tea and fruit juice to increase body water content, replenish lost water and accelerate the discharge of various metabolic wastes in the body.

3. Sheltering from the wind and sand

Exercise to increase the body's resistance is the main way to avoid colds, especially to prevent the recurrence of respiratory diseases.

When there is a sandstorm, outdoor sports should be avoided as much as possible, especially for the elderly and the infirm. You should cancel morning exercises and exercise indoors.

4. Keep indoor humidity

Experiments show that 50% ~ 60% relative humidity is the most comfortable for human body.

In windy and dusty weather, the air is very dry and the relative humidity is low, so people's throat is dry and their mouth is dry, which is easy to get angry, which can easily lead to or aggravate respiratory diseases, and also make their skin dry and lose moisture.

In this regard, humidifiers can be used indoors, and methods such as sprinkling water and mopping the floor can be used to keep the air humidity appropriate.

5. Pay attention to skin care

In dusty weather, the moisture on the surface of human skin is easily taken away by wind and dust, and the skin becomes rough.

Therefore, after going home, you should wash your face in time and apply hydrating skin care products.

6. Clean the dust in time

After entering the house from the outside in windy and dusty weather, you can rinse your mouth with clear water to clean your nose and reduce the chance of infection. If you can, take a shower and change clothes in time to keep your body clean and comfortable. Indoor dust should be cleaned in time and wiped with a wet rag to prevent dust from flying into the room and inhaling into the respiratory tract.

7. Pay attention to blocking dust when going out.

Mask: The main function is to prevent harmful gases from being inhaled into the respiratory tract. Wearing a mask can effectively prevent dry mouth and nose, itchy throat, excessive phlegm and dry cough.

Hat, silk scarf or hood: can prevent hair and exposed parts of the body from falling on dust and sand, and solve the unhappiness caused by itchy skin.

Goggles: It can reduce the probability of wind-blown sand entering the eyes, which will cause corneal abrasion, conjunctival congestion, dry eyes and tears.

Once the dust blows into your eyes, don't rub it with dirty hands. Wash or drop a few drops of eye drops with running water as soon as possible, which can not only keep your eyes moist, but also help dust flow out and play an anti-infection role.

8. It is particularly important to protect your eyes on dusty days.

Don't wear contact lenses.

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.

9. Slow down and make way.

In windy weather, drivers should slow down a little. In this weather, pedestrians and cyclists are most vulnerable to the influence of sandstorms, resulting in unclear or impatient vision, and are likely to frequently compete with motor vehicles for lanes, which is prone to danger.

10. Pay attention to personal safety

Pay attention to personal safety in sandstorm weather, try to stay away from tall buildings, and don't walk or stay under billboards or trees.

When encountering strong sandstorm weather, drivers and friends on the road should not worry, park their cars in low-lying places and wait until the strong wind has passed before driving.

1 1. Try to avoid going out.

Meteorologists remind the public that inhaling too much dust can easily lead to lung diseases, especially children, so people should try to reduce travel in dusty weather.

Finally, remember to have a good relationship with chubby friends at ordinary times, and only at critical moments can you save your life.
