Cholinergic Urticaria

Cholinergic urticaria is a type of hives triggered by an increase in body temperature. This can happen during exercise, hot baths, sweating, or stress. When the body temperature rises, small welts or itchy bumps appear on the skin. This reaction is caused by the release of histamine, a chemical in the body that causes inflammation. While it can be uncomfortable, cholinergic urticaria is usually not serious and can often be managed with antihistamines or by avoiding triggers. If symptoms are severe or persistent, it's advisable to consult a healthcare professional.
