Miliaria, commonly known as heat rash or prickly heat, is a dermatological condition characterized by the development of small, itchy, red bumps on the skin. It occurs when sweat glands become blocked or clogged, resulting in the retention of sweat beneath the surface of the skin. The condition typically emerges in hot and humid climates, or when the body is exposed to excessive heat.
The signs and symptoms of miliaria can vary, but commonly include clusters of tiny, fluid-filled blisters or raised red bumps on the affected areas, such as the face, neck, underarms, chest, back, or groin. These eruptions are often accompanied by intense itching or a prickling sensation, hence the name "prickly heat." In some cases, miliaria may also lead to a stinging or burning sensation.
Miliaria is caused by the inability of the sweat glands to release sweat properly, leading to the inflammation of the affected skin. Factors such as excessive sweating, occlusive clothing, certain medications, or prolonged bed rest can contribute to the development of miliaria.
Treatment for miliaria involves relieving the symptoms and addressing the underlying cause. This may include taking measures to keep the affected areas cool and dry, wearing loose-fitting clothing, avoiding excessive heat exposure, and using mild, non-irritating soaps. In some cases, over-the-counter hydrocortisone creams or calamine lotion may help alleviate the itching and inflammation associated with miliaria.
In summary, miliaria is a heat-induced dermatological condition characterized by the formation of itchy, small red bumps due to blocked sweat glands. It commonly occurs in hot and humid environments, and treatment involves keeping the affected areas cool and dry while addressing the underlying cause.
