# Doctor Explains Heat Rash (Miliaria) in a Baby: Causes, Symptoms, Treatment, and Prevention
Heat rash, also known as miliaria, is a common skin condition in babies, particularly during hot and humid weather. It occurs when sweat ducts become blocked and sweat gets trapped under the skin. Understanding the causes and symptoms of heat rash can help in managing and preventing this uncomfortable condition.
## Causes of Heat Rash in Babies
Heat rash is most common in babies because their sweat glands are not fully developed. When a baby gets too hot, the sweat glands can become clogged, leading to a rash. It often occurs in areas where skin can become warm and moist, such as the neck, diaper area, or skin folds.
## Symptoms of Heat Rash
The hallmark of heat rash is small, red bumps on the skin that may feel prickly or itchy. Sometimes, the rash may appear as clear, fluid-filled blisters or deeper, red lumps. Babies might appear irritable or uncomfortable due to the itchiness associated with the rash.
## Treatment and Prevention
The best way to treat heat rash is to cool your baby’s skin and prevent further sweating. Dress your baby in loose, light clothing and keep them in a cool, shaded, or air-conditioned area. Keep the affected skin dry and avoid creams or ointments that could block the pores. If needed, calamine lotion can provide some relief from itching.
Preventing heat rash involves keeping your baby cool and dry, especially during hot weather. Ensure your baby stays hydrated and avoid overdressing them. Regular baths with cool water can also help in maintaining a comfortable body temperature.
