Cold exposure is more than a seasonal nuisance for some people. Cold urticaria occurs when the immune system treats cold as a threat, releasing histamine that leads to rashes, swelling, itching, and in severe cases, anaphylactic shock.
Research shows women are affected twice as often as men, typically starting in the early twenties, though it can appear at any age. There are two types:
-
Primary cold urticaria: the most common, usually with no known cause.
-
Secondary cold urticaria: linked to underlying conditions like Epstein-Barr virus, HIV, hepatitis C, or certain blood cancers.
Symptoms may appear from exposure to cold air, swimming in cold water, consuming icy foods or drinks, or touching cold surfaces. Common signs include skin bumps, itching, redness, swelling, fatigue, fever, and joint pain.
Diagnosis is often done via a simple ice test, but this must be performed under medical supervision to avoid anaphylaxis.
Treatment generally involves antihistamines, and severe cases may require advanced medications or adrenaline as a life-saving measure.
Prevention tips:
-
Exercise caution in cold environments or during swimming.
-
Inform your doctor before surgeries due to lowered body temperature risks.
-
Monitor symptoms regularly and consult a specialist if severe reactions occur.
Experts emphasize that for some, cold is not just harsh weather but a serious health risk requiring awareness and early diagnosis.
