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

01

Dust weather refers to a weather phenomenon in which strong winds stir up a large amount of dust and sand from the ground, making the air turbid and horizontal visibility significantly reduced.

Sand and dust weather is divided into three categories: floating dust, blowing sand, and sandstorms.

Floating dust: Sand or soil particles evenly suspended in the atmosphere (mostly from other places, or left in the air after local blowing sand or sandstorms), making horizontal visibility less than 10 kilometers.

Blowing sand: The wind blows up the dust and sand on the ground, making the air quite turbid, and the horizontal visibility is within 1 km to 10 km.

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

02

When sandstorms hit, the lungs are most injured

The skin, nose, eyes, trachea and lungs are the first parts to be exposed to sand and dust. Therefore, they are affected The most obvious.

Among them, damage to direct contact parts such as eyes, nose, throat, skin, etc. mainly manifests as irritation symptoms and allergic reactions, while damage to the lungs is more serious and extensive.

When people encounter high-density sand and dust without taking precautions, it will first cause various irritating symptoms, such as runny nose, tears, cough, sputum, etc., as well as systemic reactions such as shortness of breath, fatigue, fever, and night sweats. .

These are mostly short-term symptoms, which are the body’s self-protection method of removing foreign matter. Generally, the damage will not persist.

However, sometimes the reaction can be severe, especially when exposed to high-density sand and dust for the first time or suddenly in large quantities, which can manifest as sudden shortness of breath, chest pain, chest tightness, headache, dizziness, etc. People with existing asthma, It will be more obvious in patients with chronic lung disease and heart disease.

Sand dust landing on the skin or eyes can also cause obstruction of sebaceous glands and sweat glands, leading to skin inflammation, conjunctivitis, etc.

Particles entering the lungs can lead to a decrease in the ventilation function of the bronchus and a loss of alveolar ventilation function, and can further cause various hazards.

Some studies have found that the immune function of primary school students who live in an environment polluted by particulate matter for a long time will be significantly suppressed, resulting in a decrease in the respiratory system's resistance to infection and an increase in the prevalence of respiratory diseases.

American scientists also found a correlation between fine dust particles and mortality from lung disease and heart disease. Research in Australia shows that sandstorms may be closely related to the high incidence of asthma in the country.

Not long ago, a survey in my country showed that among residents who have lived in some areas of Xinjiang for more than 30 years, a certain proportion of patients with non-occupational pneumoconiosis are closely related to the environment in which they live in blowing sand and dust. Therefore, This disease is called sand pneumoconiosis.

In addition, a large number of sand and dust particles dispersed in the air will also scatter and absorb sunlight, reducing the intensity of ground ultraviolet rays, thus reducing the effect of ultraviolet sterilization and anti-rickets.

Therefore, in areas with severe particulate matter pollution, the incidence of rickets in children increases, and the incidence of airborne diseases such as tonsillitis and colds is also higher.

To deal with sandstorms, wear a mask and drink more water

First of all, when chronic cough with sputum or shortness of breath, episodic wheezing and chest pain occurs, You need to seek medical attention as soon as possible, seek help from professional medical staff, and carry out corresponding treatment under their guidance.

Secondly, take personal protection.

When sand blows, you must reduce the chance of exposure to sand and dust when going out and close doors and windows in time.

If you must do outdoor activities due to occupational needs, it is best to use dust-proof and dust-filtering masks to effectively reduce the dust inhaled into the body.

You can use wet towels, gauze towels, etc. to protect your eyes, mouth, and nose, but this simple protection cannot block fine particles with small particle sizes. Other protective measures include wearing appropriate glasses, dust-proof gloves, footwear, and clothing to protect your eyes and skin, and washing your face frequently (especially before eating).

Construction workers, cleaning workers, etc. should temporarily stop outdoor work until the sandstorm recedes.

Third, drink more water.

During the season when sandstorms are common, the weather is dry and dusty, and the moisture on the surface of the skin is easily lost, resulting in rough skin, and dust entering the pores is prone to clogging. If it is not removed in time, it may cause acne, and people with allergies are also prone to various allergic dermatitis and rashes.

Drinking more water can replenish lost water in time and speed up 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 children with poor physical resistance, and those with respiratory allergic diseases are "vulnerable" and should pay more attention to health care during the sandstorm season and stay away from sand and dust as much as possible.

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

How to deal with sandstorms?

1. Early prevention

Prevention is better than cure. In windy, dry and dusty weather, microorganisms such as bacteria, viruses and mycoplasma are active and conducive to spread, which can easily induce pharyngitis, Nosebleeds, dry eyes, keratitis, tracheitis, asthma, etc.

You can usually take throat lozenges to keep your throat cool and comfortable; drop eye drops several times to prevent dry eyes; in case of nosebleeds, you can often apply a few drops of dry oil around the nostrils to keep the nasal cavity clear Moisturizing to prevent capillary rupture and bleeding.

2. Drink more water and eat more fruits

Dry and dusty weather is prone to cleft lips, dry and itchy throat, smoke from the nose, etc., which is what people call getting angry and causing the body to suffer from internal heat. Lack of water can also cause difficulty in defecation, causing hemorrhoids, anal fissures, and bloody stools.

Drink more porridge, soup, tea, and juice to increase the body's water content, replenish lost water, and speed up the discharge of various metabolic wastes in the body.

3. Exercise to avoid wind and sand

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

When there is wind and sand, you should try to avoid outdoor exercise, especially the elderly and the infirm. They should cancel morning exercises and exercise indoors.

4. Maintain indoor humidity

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

In windy and sandy weather, the air is very dry and the relative humidity is low. People have dry throats and mouths and are prone to getting angry, which can easily cause or aggravate respiratory diseases. It can also make the skin dry and lose moisture.

In this regard, humidifiers can be used indoors, as well as methods such as sprinkling water and mopping with wet mops to maintain appropriate air humidity.

Hat, scarf or hood: It can prevent hair and exposed parts of the body from dust and solve the discomfort caused by itchy skin.

Goggles: It can reduce the probability of wind and sand entering the eyes. Wind and sand blowing into the eyes can cause corneal abrasions, conjunctival congestion, dry eyes, and tearing.

Once dust and dust are blown into the eyes, do not rub them with dirty hands. You should rinse them with running water or apply a few drops of eye drops as soon as possible. This will not only keep the eyes moist and make it easy for dust to flow out, but also can prevent infection. role.

8. It is especially important to protect your eyes on sandy days

Do not wear contact lenses.

The sudden high and low temperature changes and declining air quality make it easy for people to catch colds, which can lead to viral conjunctivitis and viral keratitis. The eye environment at this time is very fragile.

Myopic people should try to wear ordinary frame glasses in dusty weather. On the one hand, the glasses play a protective role and prevent dust from entering the eyes. On the other hand, once sand particles enter the eyes, , the tears secreted by the tear glands can also wash away the particles in time.

Contact lenses are relatively fixed to the surface of the eyeball when worn. When dust accidentally enters the eyes, it can easily adhere to the contact lenses, causing bacteria to breed. If you wear contact lenses frequently and do not pay attention to eye hygiene, , which can easily aggravate inflammation.

9. Slow down and give way when driving

In sandy weather, drivers should slow down slightly. In this kind of weather, pedestrians and cyclists are most likely to be affected by the blowing sand, causing blurred vision or impatient mood. They are likely to frequently compete with motor vehicles for the road, which is prone to danger.

10. Pay attention to personal safety

Pay attention to personal safety during blowing sand weather. Stay away from tall buildings as much as possible, and do not walk or stay under billboards or trees.

When encountering strong sandstorm weather, drivers on the road should not rush. They should park their cars in low-lying areas and wait until the strong winds pass before driving.

11. Try to avoid going out

Meteorological experts remind the public that inhaling too much sand and dust can easily cause lung diseases, especially for children The greatest harm is caused, so people should try to reduce travel during sand and dust weather.

Finally, remember to have a good relationship with your chubby friends, which can save your life at critical moments.
