Miliaria, also called heat rash, is a skin disease that presents as small clear blisters or bumps. Itchiness and redness may also be present. Complications may include subsequent bacterial skin infection, increased sweating, or poor ability to temperature regulate.

Risk factors include a hot and humid environment, exercise, fever, and poorly breathable material against the skin. The underlying mechanism involves sweat gland blockage. There are three types crystallina, rubra, and profunda. Diagnosis is based on symptoms.

Treatment involves a cooler and dryer environment and loose fitting clothing. Calamine lotion may also help. Occasionally corticosteroid or antibiotic creams may be used. The condition generally resolves after a few days of cooler temperatures.

Miliaria is common. Up to 10% of newborns are affected, often around the first few week of life. Up to 30% of people who newly move to the tropics are also affected. The term is named for the small seeds known as millet.
