Can cold weather trigger an allergic reaction? Here's what experts say
Woman develops painful, itchy reaction after exposure to cold aisle. Experts explain causes and treatment
Cold weather may bring more than just a chill—some people experience allergic reactions triggered by exposure to cold conditions.
Kirsten Evans shared a video on social media showcasing her reaction, which occurred after simply walking down the fridge aisle at a supermarket.
"These rashes are called hives or urticaria. They cause an intensely itchy rash and, in some cases, may be accompanied by angioedema (swelling)," explains Mariam Hanna, allergist and clinical immunologist with CSACI.

Canadians accustomed to extreme winter weather are not immune to this issue. For some, symptoms may only last a few months or years, though rare cases could persist for over a decade. According to Hanna, this reaction is an immune response, and medications can help manage symptoms.
Testing for cold urticaria can be done at an allergist's office, where an ice cube is placed on the skin to check for a reaction.
For simple relief, reduce cold exposure and dress warmly while outdoors. If symptoms continue, consider consulting a healthcare provider to explore treatment options.
While uncommon, cold urticaria can significantly impact daily life, but solutions are available to alleviate symptoms effectively.
