Cold Urticaria

Cold urticaria is a type of hives that occurs when the skin is exposed to cold temperatures. It can happen when you are in cold weather, swim in cold water, or even touch cold objects. When exposed to cold, the body reacts by developing itchy, red welts on the skin. This reaction can vary in severity; in some cases, it may lead to swelling and discomfort. Cold urticaria is caused by an abnormal response of the immune system, and management typically involves avoiding cold exposure and possibly using medications to help control symptoms.
