Heat Allergy: Is It Rare?
Heat allergy, or solar urticaria, is a rare condition in which exposure to ultraviolet (UV) or visible light causes an allergic reaction in the skin. This reaction is typically experienced as a red, itchy rash that can be quite uncomfortable. Although heat allergy is rare, it can affect anyone of any age.
Symptoms of Heat Allergy
Symptoms of heat allergy can vary, but typically include a red, itchy rash on the areas of the skin that were exposed to the light. This rash may be accompanied by swelling, burning, or stinging sensations. In more severe cases, the rash can spread to other parts of the body.
Diagnosing Heat Allergy
The best way to diagnose heat allergy is through a physical exam and a review of the patient's medical history. Doctors may also use a phototest, which involves exposing a small area of the skin to light and then observing it for signs of an allergic reaction.
Treating Heat Allergy
Treatment for heat allergy typically involves avoiding exposure to UV or visible light as much as possible. Other treatments may include the use of antihistamines or corticosteroids, as well as phototherapy. In some cases, a doctor may prescribe an immunosuppressant medication.
Living with Heat Allergy
Living with heat allergy can be difficult, as avoiding exposure to UV or visible light is essential. People with this condition should wear protective clothing, use sunscreen, and avoid direct sunlight as much as possible. Limiting outdoor activities and finding ways to stay cool can also help manage symptoms.
