Sweating-induced pruritus (itching) may be caused by cholinergic urticaria, which is commonly associated with factors such as physical exercise, heat sensitivity, or emotional stress. Symptoms—including sweating and itching—may occur when body temperature rises slightly due to exercise, consumption of hot food, emotional changes, alcohol intake, hot showers, or febrile illnesses; this is typically related to thermoregulatory dysfunction. It is recommended that appropriate treatment be undertaken under the guidance of a physician.
