Spring is the season of blooming flowers, which makes us enjoy our eyes, but also encounter some small problems, such as pollen allergy. At present, the number of people allergic to pollen around the world is increasing year by year, so how to prevent pollen allergy in spring? The following tells you some common pollen allergy prevention measures. How can you tell if you are allergic to pollen? Firstly, pollen allergy is gradually identified from the usual colds; secondly, people’s health care awareness is gradually increasing and allergen testing technology is becoming more accurate. Of course, there are still many people with pollen allergy who mistakenly think they have a cold or rhinitis and repeatedly use anti-cold medicine or rhinitis drops to treat them, thus delaying the best time for treatment. Therefore, identifying the correct symptoms is the first step. Pollen is generally about 30 to 50 microns in diameter, and when they are dispersed in the air, they are easily inhaled into the respiratory tract. When people with pollen allergy inhale these pollen, they will have an allergic reaction, which is called pollen allergy. The main symptoms of pollen allergy are sneezing, runny nose, watery eyes, itchy nose, eyes and external ear canal, and in severe cases, bronchitis, bronchial asthma and pulmonary heart disease (mostly in summer and autumn). The reason why pollen causes allergies in humans is that pollen is rich in proteins, and certain protein components are the main allergens that produce allergies. The symptoms of skin contact pollen allergy are erythema, papules, fine scales, itching or burning sensation on the skin, mostly caused by sun exposure after skin contact with pollen in the wild. So, how to prevent pollen allergy? First, avoid all suspected or known allergens, such as: a large amount of pollen floating in the air during the pollen season; Second, for some known allergens, once identified, immediately transfer the patient’s living environment, such as: around the patient’s housing planted with some flowers, trees, allergic people should remove these allergens. Children should not be allowed to stay and play for long periods of time in grassy areas, very leafy yards or forests. These are only passive preventive measures. To really cure pollen allergy, one must desensitize. Preventive measures for pollen allergy: 1. Do not stay outdoors for long periods of time. Stay outdoors as little as possible during the day, especially at times of the day when the pollen index is high, such as in the evening on sunny days. If you want to do outdoor activities and sports, choose the time when the pollen index is lowest, such as early in the morning, late at night, or after a rain shower. 2. Close windows and doors tightly. Close windows and doors during the day to prevent pollen from flying in. 3.Don’t dry clothes outside of the house If possible, dry your clothes inside the house (using a clothes dryer is better), and don’t dry your clothes outside, otherwise your clothes, sheets and bed sheets will be easily contaminated with pollen. 4.Change your clothes If you go out when the pollen index is very high, remember to change into clean clothes when you come back. 5. Wear glasses Wearing glasses can reduce the chance of your eyes being affected, so you may want to use glasses with lenses instead of contact lenses, or bring sunglasses when you go out. 6. Avoid allergy season If possible, schedule your vacation during your hay fever season and take the opportunity to avoid it. Consider a vacation to the beach, as the sea breeze will make the air almost pollen-free, or consider choosing a vacation to a country where there are no triggers that will cause your allergies.
