A few words of thanks would be greatly appreciated.

Dust allergy


A dust allergy is an abnormal reaction of the body when it comes in contact with certain substances found in house dust. These allergens are diverse: mites, hairs, fibers, fungi, molds, pollen ... Therefore, dust allergies can be identified and for the most part refer to an allergy to dust mites, a major component of dust. These kinds of microscopic spiders, invisible to the naked eye, feed on animal or plant debris and evolve by thousands in every house (carpets, bedding, curtains...).


The symptoms that occur are often the same as those of a common cold: stuffy nose, sneezing, red eyes, cough, or common allergic asthma. Rashes and itching and types of eczema can also be symptoms of an allergic reaction. If the allergy has significant impact on daily life, an allergist will be able to confirm the diagnosis of an allergy to dust mites by skin tests or blood tests.


Antiallergic drug (including antihistamines that fight against the release of histamine, a molecule involved in allergic reactions) solutions exist, but as with any allergy, one should first and foremost get rid of allergens in the daily home environment. This requires of course that furniture be dust with a damp cloth, your rooms be vacuumed regularly and ventilated to avoid excessive heating, as mites tend to proliferate within heat and humidity. Getting rid of mites also requires optimal hygiene of one's bed, with regular washing at 60°C and the use of pillowcases and mattress covers impervious to dust mite allergens.
