Cold allergy, also known as cold urticaria, is a medical condition in which exposure to cold temperatures causes an allergic reaction in the skin. The symptoms of cold allergy include itching, hives, swelling, and redness of the skin. In some cases, exposure to cold temperatures can also cause systemic symptoms, such as difficulty breathing, chest tightness, and fainting.
Cold allergy is caused by an abnormal immune response to cold temperatures. When the skin is exposed to cold temperatures, the immune system releases histamine and other chemicals that cause the symptoms of an allergic reaction. Cold allergy can be triggered by a variety of cold stimuli, including cold air, cold water, and even holding cold objects.
Diagnosis of cold allergy is typically based on a physical exam, a medical history, and sometimes, allergy testing. Treatment for cold allergy typically involves avoiding exposure to cold temperatures and taking medications such as antihistamines to reduce symptoms. In severe cases, a healthcare professional may prescribe epinephrine, a medication used to treat severe allergic reactions.
It is important to consult a healthcare professional if you experience symptoms of cold allergy, as the condition can be potentially life-threatening in some cases. With proper management and treatment, most people with cold allergy can avoid triggering factors and live normal, healthy lives.
