Urticaria, commonly known as hives, is a skin condition that affects millions of people worldwide. It is characterized by the sudden appearance of raised, red, itchy bumps on the skin that can vary in size and shape. While there are many different types of urticaria, two of the most common are urticaria due to cold and heat.
Urticaria due to cold, also known as cold urticaria, is a type of urticaria that occurs when the skin is exposed to cold temperatures. This can be caused by exposure to cold air, cold water, or even cold objects. Symptoms of cold urticaria can include itching, redness, and swelling of the skin.
Urticaria due to heat, also known as cholinergic urticaria, is a type of urticaria that occurs when the body temperature rises. This can be caused by exercise, emotional stress, or even hot showers. Symptoms of cholinergic urticaria can include small, itchy bumps on the skin, sweating, and flushing of the skin.
The exact cause of urticaria due to cold is not known, but it is thought to be an immune system reaction. Cold urticaria can be triggered by exposure to cold temperatures, such as being outside in cold weather or swimming in cold water. Some people may also develop cold urticaria as a result of an underlying medical condition, such as an infection or autoimmune disorder.
The exact cause of cholinergic urticaria is also not known, but it is thought to be related to the release of histamine in response to elevated body temperature. This can be triggered by a variety of factors, including exercise, emotional stress, and exposure to hot water or steam.
If you suspect that you have urticaria due to cold or heat, it is important to see a dermatologist for a proper diagnosis. Your dermatologist may perform a skin prick test or blood test to help determine the underlying cause of your symptoms.
Preventing urticaria due to cold and heat can be challenging, but there are some steps you can take to reduce your risk. For cold urticaria, it is important to avoid exposure to cold temperatures whenever possible. For cholinergic urticaria, avoiding triggers such as exercise, hot showers, and emotional stress can help prevent symptoms.
