Last week we talked about dust mites and how these affect our health. We know that mites are a type of arachnids found in the dust and that can produce respiratory allergy and asthma problems. But, let's see concretely what is allergy to dust mites: First, it is important to note that respiratory mite allergy is one of the most widespread. Erroneously it is called dust allergy but what actually causes allergies are proteins present in the feces of the dead bodies. These antibodies, by binding to antigens, are the trigger of allergic reaction, causing inflammation and irritation of the upper and lower airways, leading to the typical symptoms: rhino-conjunctivitis and asthma. Most commonly in allergy it is to suffer itchy nose and eyes, runny nose, sneezing, dry cough and shortness of breath. The main problem of dust mite allergy is that it is very difficult to avoid, because dust mites are everywhere and it is almost impossible to escape from them. They nestle in beds and especially in mattresses, pillows, comforters and bedspreads and are invisible to our eyes. Dust mite allergy, besides being the most common domestic allergy, is one of the causes of asthma more common in children. It is therefore important to take certain precautions, as this disease can end up deteriorating the quality of life of people if it worsens. Thus, it is important to avoid exposure to the allergen as much as possible. There are devices with specialized technologies that reduce these effects and become a necessary tool for allergic people in their fight against dust mites. In addition, it is able to create an environmental health at home that is beneficial for all its inhabitants, whether or not allergic to dust mites.
