What are allergies?

Allergic reactions are messages that the immune system sends to the body. The messages can be almost unnoticeable and appear suddenly, e.g. when we use lotions or eat food we cannot tolerate.

In order to develop allergies you have to be exposed to one or more allergens for a period of time. It is not possible to develop an allergic reaction to an allergen the first time you come into contact with it. However, if you have been exposed to an allergen over an extended period of time, even short contact with the allergen can bring out an allergic reaction. The most common allergens in Denmark are birch pollen, grass pollen, wormwood, horses, dogs, cats, dust mites, outdoor mould fungus, which most often cause symptoms of the airways, and certain fragrances, which cause contact eczema. If you suspect that you or someone in your family suffers from contact eczema (also known as contact dermatitis), we advise you to contact your physician.
