It's allergy season again, and the real "culprit" is actually this! How to prevent it →

Every spring, many people will suffer from pollen allergies. What is the "culprit" of spring pollen allergies? How to get through the pollen allergy season? Let's find out together↓↓

There are two types of pollen transmission

Wind-borne pollen is the main allergen

Experts say that pollen is spread in nature mainly in two forms: wind-borne and insect-borne. The "culprit" of spring pollen allergies is often not brightly colored ornamental flowers, but trees and weeds that do not look like they will bloom.

Insect-pollinated pollen, such as pollen from rapeseed, peach and pear flowers, is spread by insects such as butterflies and bees. It is characterized by bright flowers with fragrance or other odors, large pollen grains, small amounts of pollen, and is not easily spread, and usually does not cause allergies.

Wind-borne pollen, such as pollen from cypress, poplar, willow, birch, sycamore, etc., is characterized by small flower shape, high pollen content, light weight, and can be flown to far places by the wind. Wind-borne pollen is the main allergen.

Li Lisha, from the Department of Allergy, Peking Union Medical College Hospital: Some sensitive patients may have symptoms in late February, but most patients have more severe symptoms in late March. In March, the main pollen trees are cypress and willow, while in April and May, the main pollen trees are birch, sycamore, and ash , all of which may cause pollen allergies.

Spring pollen allergy

Can cause a variety of adverse reactions

Spring pollen allergy is an allergic reaction disease. After contact with pollen, some patients usually experience eye symptoms such as itchy eyes, tearing, or conjunctival congestion, and may also suffer from photophobia.

Wang Lianglu, executive deputy director of the Department of Allergy at Peking Union Medical College Hospital: There are indeed some targeted preventive measures now, such as wearing masks and goggles during the pollen season. Goggles must be sealed to cover the eyes completely.

Experts say allergic rhinitis is a common disease caused by pollen. Nasal congestion, itchy nose, runny nose, sneezing, and itchy eyes are the main symptoms of allergic rhinitis.

Compared with colds, allergic rhinitis generally does not cause sore throat, fever or other systemic discomfort symptoms, and generally lasts for more than 2 weeks. Allergic rhinitis patients often develop the disease at a fixed time every year. At present, there is no way to completely cure allergic rhinitis, but early intervention can alleviate the patient's symptoms.

Wang Lianglu, executive deputy director of the Department of Allergy at Peking Union Medical College Hospital: When you wake up in the morning, you can first do nasal irrigation, then use nasal spray hormone, and then use pollen barrier. This can prolong and enhance the effect of nasal spray hormone, which can play a good preventive as well as therapeutic role.
