For some, winter becomes a reason for joy: snow, New Year holidays, bright garlands and home comfort. And for some, the cold snap becomes a real test. This applies to those whose body is exposed to an increased reaction of the body to low temperatures. We talk about the main symptoms of cold allergies and effective treatment tactics.
Cold allergy is a pathological condition, which is characterized by the development of a reaction of the skin to low air temperature.
The development of cold allergy is associated with a gene mutation — more precisely, genes that are responsible for skin sensitivity to cold. As with normal allergies, exposure to a specific allergic trigger creates immune complexes. They trigger several reactions (from itching to hyperemia). Accordingly, in the case of an allergy to cold, low air temperature becomes a trigger. But specifically in this situation, they are not persistent, as they disappear after warming up.
Depending on the course, allergies can be primary, acute, recurrent (manifested every year in winter), reflex (rashes appear around the cooled area of the skin) and domestic (transmitted at the genetic level.
