Less than a month that spring has arrived, a season that, according to experts, this year will be "high risk" for allergy sufferers. Especially in terms of pollen allergy, the most common of all respiratory allergens. Pollen allergy is caused by pollen from plants, trees and grass and in the vast majority of cases, the disease has no cure and the only solution is to control symptoms with the help of medical treatment. But let's see exactly what is pollen allergy: Pollens are tiny grains that are produced by the male reproductive system of flowers and that carry sperm cells to fertilize the female reproductive system. Thus, a single plant can produce thousands of pollen grains. People with pollen allergy perceive this substance as a harmful agent in their body, which generates an immune response by histamine (a chemical released by the body itself), causing sneezing, itchy and watery eyes, congestion, asthma and other common symptoms of allergies. In addition to the proper effect of nature, climate change is contributing greatly to this problem because it is altering the flowering seasons and the pollution of the cities. It has been found that plants living in urban centers generate more aggressive polllen proteins due to pollution, bad news for allergy sufferers because this trend will probably increase. In fact, in the last 15 years they have doubled allergic diseases in the western world and it is estimated that their presence increases every year between 1 and 2%. If this continues, the European Academy of allergy and Clinical Immunology (EAACI) estimates that in less than two decades, half of Western population will duffer some form of allergy. It is important to be aware that although pollen allergy is not a serious disease, it can worsen with time in some cases if certain precautions are not taken.
