Humid tetter is a dermatological condition characterized by red, itchy, and inflamed patches of skin that occur due to excessive humidity or moisture. Also known as intertrigo or intertriginous dermatitis, it primarily affects skin folds and areas of the body where skin surfaces come into contact with each other, such as under the breasts, in the groin, armpits, and between the toes.
Humid tetter occurs when sweat or other bodily fluids accumulate in these moist environments, creating a favorable condition for the growth of microorganisms like bacteria, fungi, or yeasts. The resulting infection and inflammation can lead to symptoms like itching, burning, soreness, and the development of a rash.
The condition is most common in warm and humid climates, or during hotter months, when sweating is increased. It can also be triggered by wearing tight or restrictive clothing that traps moisture against the skin, obesity, poor hygiene, or underlying medical conditions that cause excessive sweating or affect immune function.
Prevention and treatment of humid tetter include keeping the affected areas clean and dry, using powder or antifungal medications to inhibit microbial growth, wearing loose-fitting clothes made of breathable fabrics, and maintaining a healthy weight. In severe cases, consulting a dermatologist may be necessary for prescription-strength treatments such as topical steroids or oral medications.
