Why pollen allergy?

Pollen allergy is a common phenomenon, especially during the blooming season. Allergic reactions occur because the immune system recognizes pollen as a foreign particle that has entered the body and needs to be destroyed. The release of substances that kill pollen causes allergy symptoms that are uncomfortable for many people.

1. Causes of pollen allergy

Pollen is one of the most common allergens. Allergic reactions to pollen come from the immune system. Instead of recognizing pollen as harmless particles when entering the body, the immune system sees it as a foreign object that needs to be destroyed. The reason for this false identification is because the composition of pollen contains substances such as protein, cellulose, pentose, dextrin, phosphorus that easily stimulate immune responses.
Allergenic pollens are usually very small in size, usually less than 0.5mm. Pollen from plants, wind-pollinated plants are more likely to cause allergies than other flowering plants. Pollen allergies usually don't cause serious health problems, but they can be frustrating due to immune system reactions.
