What is Cold Urticaria?
What is Cold Urticaria? Cold urticaria is a skin reaction to cold which causes the appearance of itching wounds and the skin becomes reddish. The severity of cold allergy symptoms that appear on each person is different. Some people may lose consciousness, have very low blood pressure, and even the worst can cause death. Teen age is the age most commonly affected by cold allergies, but usually disappears completely within a few years.
Cold Urticaria Symptoms
Usually cold allergy symptoms appear when the skin is exposed to cold water or cold weather (below 4 degrees Celsius). Cold allergy is also more risky to appear in conditions that are windy and moist. The following are some of the cold allergy symptoms that can occur:
- Hands feel swollen when holding a cold object.
- Appearing itchy rays on the skin area exposed to cold air.
- Lips and throat feel swollen when eating cold food or drink.
- Reddish skin.
Allergic reactions are usually most severe when the entire body is exposed to cold temperatures, such as when swimming in cold water. The reactions can potentially endanger life, such as swelling of the throat and tongue making breathing difficult, blood pressure dropped dramatically, heart palpitations, fainting, and swelling of the arms and legs.
In general, cold allergies will disappear by itself after a few weeks or months, but some are lasting longer. If the throat or tongue feels swollen, feeling dizzy, and difficulty breathing, see a doctor immediately.

Cold allergic reactions occur when the release of histamine and other chemicals into the bloodstream triggered by cold weather. Some things are suspected to be the cause of cold allergies, including genetic factors have too sensitive skin cells, viruses or certain diseases. But the exact cause why the body reacts so to the cold is unknown.
There are several factors that can increase the risk of cold allergies, namely:
