Heat Allergy

Home   >   Allergies   >   Heat Allergy

Heat allergy or heat urticaria is not an allergy to the heat, but rather a reaction to something that may be activated by heat. That is, heat is an indirect cause of the reaction.

The reaction is not well understood, but a possible cause may have to do with how sweat and heat make your body or the allergens themselves more reactive. Certain reactions may not be an allergy at all, but instead a reaction to the sun, or irritation of the skin by clothing fibers. Skin on hot, sweaty parts of the body which may rub against clothing can be more susceptible to this type of reaction.
