Allergies which can coexist with cold allergies:

Atopy
A predisposition toward developing certain allergic hypersensitivity reactions with a hereditary component. Contact with the allergen must occur before a reaction can develop.  A person with atopy typically presents with one or more of the following: eczema (atopic dermatitis), allergic rhinitis (hay fever), and/or allergic asthma.

Food Allergies
Any food may cause an allergic reaction, but 90% of food allergies in children are caused by just 6 common foods or food groups—milk, eggs, peanuts, tree nuts, soy, and wheat. In adults, a similar percentage of serious allergies are caused by just 4 foods—peanuts, tree nuts, fish, and shellfish

Physical Allergies
Physical allergies are allergic reactions to cold, sunlight, heat, or minor injury.

Asthmas
Asthma is a chronic lung condition. Inflammation, increased mucus, and muscle tightening cause the airways to narrow, and as a result, air can’t move through the lungs as well as it should, which makes it difficult to breathe.

Nuggets of Wisdom

Yes, there is such a thing as having an allergic type reaction to temperatures. This is defined as a physical urticaria. Other physical urticarias include Solar, Aquagenic, Pressure, Vibration and Exercise.

Most reactions are pseudo-allergic. By definition, an allergy involves inhaling or consuming an allergen. Physical urticarias have no known allergen. Despite the terminology and medical definitions, systemic reactions can be life threatening.

Cold has an arbitrary definition based on an individual feeling. For a person with a cold urticaria, cold can be defined as any temperature cooler than their own body temperature.

You do not have to be cold to have a reaction to the cold; contact with cold can trigger a reaction.

You can have an allergic type reaction to both cold and heat simultaneously.

Most reactions considered anaphylactic are really anaphylactoid by definition.

Moving to a warmer climate as a treatment for Cold Urticaria is a myth. Warmer climates present their own issues for those with Cold Urticaria.
