What is the manifestation of pollen allergy? How to effectively prevent pollen allergy?

Allergy refers to respiratory tract and eye allergy caused by pollen allergy. It is also an allergic reaction of specific individuals to pollen. There has been a so-called "hot cold" in China for a long time, which means that patients can suddenly have respiratory catarrh symptoms when the weather is hot in summer and autumn. So what are the manifestations of pollen allergy? How to effectively prevent pollen allergy?

What about pollen allergy?

The treatment of pollen allergy is generally antihistamine treatment.

Antihistamine treatment is the use of antihistamines, such as chlorpheniramine, chlorpheniramine, mink, kairuitan and so on.

Its disadvantage is that antihistamine therapy only works on histamine, an allergic medium, and has little effect on allergies caused by other allergic media. Antihistamines temporarily solved allergic symptoms, but the basis of allergic occurrence has not changed. Stimulated by allergens, allergic mediators are still released, so even if antihistamines are cured for a period of time, they will still recur.

Moreover, the use of various hormones, antihistamines, antibiotics and other drugs will make the patient's regulatory mechanism more onerous, which will seriously interfere with the patient's original accurate endocrine system, and will also cause the imbalance of normal intestinal flora, further affecting the patient's intestinal absorption function, vitamins and various trace elements. Heterogeneous substances are easily absorbed into the body, which makes the patient enter a vicious circle. After stopping the drug, the patient's condition will be repeated, and sometimes injection desensitization will trigger the allergic reaction of the patient.

The negative effects of this antagonistic therapy have been recognized by more and more patients and clinicians.

For a long time, traditional medicine has not found an effective way to cure allergic diseases. The extensive use of flavanolamine and hormones only plays a role in relieving symptoms, with great side effects, especially on the development of infants, children and adolescents. Allergic patients relieve symptoms after repeated attacks for many years, and their immune ability is getting lower and lower, which is extremely painful.

The most effective measure to treat intractable allergy is to find out allergens, but it is like finding a needle in a haystack to accurately find the pathogenic factors among the different inducers of 3000 common plant pollen.

Pollen allergy symptoms

Pollen is generally about 30 ~ 50 microns in diameter. When they float in the air, they are easily inhaled into the respiratory tract. People with a history of pollen allergy will have allergic reactions after inhaling these pollen, which is pollen allergy.

In nature, pollen is a major allergen. Whenever it is in full bloom in spring, seed trees, such as holly, castor, Kochia scoparia and Platanus acerifolia, are most likely to cause pollen allergy. These plants have a large amount of pollen, small volume and high content in the air, which is easier to spread in windy days, so there are more people who are allergic to pollen when they travel in spring.

Pollen can cause human allergy because it is rich in protein, and some protein ingredients are the main allergens.

Pollen allergy has three main manifestations.

1, "Pollen allergic rhinitis", itchy nose, sneezing, runny nose, stuffy nose, poor breathing, etc.

2, it is "pollen allergic asthma", which is characterized by paroxysmal cough, dyspnea, white foam-like mucus, and sudden onset and aggravation of asthma, which is no different from normal people;

3, it is "pollen allergic conjunctivitis", which is characterized by itchy eyes and swollen eyelids in children, often accompanied by watery or purulent mucus secretions.

According to the research data, each plant can produce hundreds of millions of pollen, and in some areas, the pollen produced per square kilometer exceeds 10 ton. In windy and dry weather, pollen concentration in the air is higher. Pollen floating in the air can easily cause allergic symptoms in sensitive people. China has a vast territory, and allergic pollen in different regions is not consistent. Wild Artemisia pollen is the main pollen in the north, but ragweed is distributed in the north and south of the Yangtze River, which should be paid attention to.

How to effectively prevent pollen allergy

1. Don't stay outdoors for a long time: stay outdoors as little as possible during the day, especially when the pollen index is high every day, such as on a sunny night. When doing outdoor activities and various sports, try to choose the time with the lowest pollen index, such as early morning, late at night or after a shower.

2. Wear glasses: Wearing glasses can reduce the chance of eyes being affected, so you might as well change your contact lenses into glasses with lenses, or take sunglasses when you go out.

3. Change clothes: If you go out when the pollen index is high, remember to put on clean clothes when you come back.

4. Close doors and windows: Close doors and windows during the day to prevent pollen from flying.

5. Avoid allergy season: If possible, arrange your holiday in your hay fever season as much as possible and seize the opportunity to avoid it. Consider going to the seaside for a holiday, because the sea breeze will leave almost no pollen in the air, or you can consider choosing a country without allergic factors.

6. Don't dry clothes outdoors: Try to dry clothes indoors (it is best to use a dryer), and don't dry clothes outdoors, otherwise clothes, sheets, sheets, etc. will be sunburned. It is easily contaminated by pollen.

7. Install vehicle-mounted filter: Consider purchasing vehicle-mounted air filter. If you are considering buying a new car, you might as well buy a car with a pollen filter in the air conditioner. This kind of small filter element has become more and more common, not only in luxury cars, but also in cars.

8. Avoid pollutants: Avoid anything that will aggravate symptoms, such as dust and various smells on the road.

9. medication: in the season when flowers are in full bloom, allergies are sometimes inevitable. At this time, antihistamines sold in pharmacies will be of great help to your allergic symptoms. If the symptoms are serious, you should seek medical attention as soon as possible. Generally speaking, the doctor will give you cromoglycine, oral hormone and other drugs with stronger efficacy.

10, quit smoking: smokers with allergies should stop smoking.
