A. Allergy is skin bumps When it comes to allergy, people are often the first to think of skin allergy, bumps, but in fact, especially when pollen allergy, mainly in the five senses, appear continuous sneezing, runny nose, nose blockage, itchy, red eyes, itchy ears, palate, throat, etc., in serious cases will appear paroxysmal cough, wheezing, breathing difficulties, that is, suffering from allergic rhinitis, allergic Conjunctivitis, bronchial asthma, etc. Second, pollen is only allergic to contact In the cartoon “Snow White” there is a dwarf who is allergic to pollen, he smelled a beautiful bouquet of flowers and immediately wanted to sneeze and eventually burst into a huge sneeze. In real life, there are people who get goose bumps when they stand under a tree where peach blossoms are in full bloom. But in most cases, how can people be allergic to pollen when they are not exposed to flowers? It turns out that it is caused by the pollen of wind-borne flowers. Wind-borne flowers are pollen that is spread by the wind as a medium. These flowers are small, inconspicuous, and unscented, and their pollen is light, with a large amount of pollen that can be dispersed hundreds or even thousands of kilometers by the wind. And the flowers are large and showy is the insect vector flowers, there are nectar glands, not easy to drift, if not deliberately contact, generally do not cause the disease. Third, there is no pollen in autumn, so you will not be allergic to pollen. In spring, when flowers are in bloom, there is pollen; in autumn, when fruits are harvested, there should be no pollen, right? This is not the case. In spring, it is mainly tree pollen that makes people allergic, while in autumn, weed pollen is the main cause. Moreover, autumn pollen has a long flowering period, which lasts for 1-2 months. Every year, after autumn, a small amount of pollen begins to drift, gradually reaching a peak by the end of summer, and then maintaining a high concentration. In late August and early September, when pollen allergy symptoms are at their worst, most pollen allergy sufferers will develop bronchial asthma if it coincides with thunderstorms, and in mid to late September, after the bloom period, symptoms will gradually ease and heal around the National Day. In the north, common allergic pollens come from artemisia, grasses, quinoa and amaranth. Artemisia spp., including Artemisia absinthium, wild artemisia, large-seeded artemisia, and yellow-flowered artemisia, are rare in the south. After crossing the Yangtze River, people with otherwise severe pollen allergies will suddenly feel relieved and free of illness. The grass, also known as Lala vine, is distributed throughout the country. Artemisia spp. and grass are the two main allergenic pollen plants in the Shijiazhuang area. They are extremely vigorous, and the wilderness, fields, and the front of the house are all places for them to survive. Attachment: Medical knowledge of pollen allergy prevention and control What should I do if I am allergic to pollen? First, we should try to avoid allergens, such as not going to the countryside, wearing masks, or moving to the south if you are allergic to pollen. Second, apply medications to reduce symptoms, such as antihistamines and topical glucocorticoids. Pollen allergy comes and goes every year, and the cycle goes on and on. Because allergies are related to body composition, pollen allergy sufferers should be treated with specific immunotherapy based on the identification of allergens, i.e. desensitization therapy. It is the only treatment recommended by the World Health Organization that can affect the underlying mechanism of allergic diseases and thus change their natural course.
