Heat Urticaria

Heat urticaria is a type of hives that occurs when your skin is exposed to heat or warmth. This can happen from activities like exercising, taking a hot shower, or spending time in the sun. The body responds to the heat by releasing chemicals like histamine, which leads to the development of itchy, red welts on the skin. These welts can appear quickly and may disappear within hours. While uncomfortable, heat urticaria is usually temporary and can be managed by avoiding triggers and using antihistamines to reduce symptoms. If it persists, seeking medical advice is recommended.
