Miliaria (Heat Rash)

What is Miliaria (Heat Rash)?

Miliaria, commonly referred to as heat rash, is a skin condition characterized by small, itchy red bumps caused by the blockage of sweat ducts. The blockage traps sweat beneath the skin, leading to inflammation and rash.

What causes Miliaria?

Heat rash arises due to:

• Excessive sweating, often in hot, humid environments

• Immature sweat ducts in newborns, making them prone in their initial weeks of life

• Wearing tight or heavy clothing that traps sweat

• Intense physical activity that promotes heavy sweating

What are the symptoms of Miliaria?

Symptoms of heat rash include:

• Small, red bumps or blisters on the skin, commonly on the chest, neck, back, and folds of the skin

• Prickly or itchy sensation in the affected areas

• Redness and mild swelling

• Discomfort or a stinging sensation when sweating in the affected area

How do I treat Miliaria?

Miliaria usually resolves on its own, but the following can alleviate discomfort:

• Keeping the affected area cool and dry

• Applying cold compresses to the rash

• Wearing loose, lightweight clothing

• Using calamine lotion or topical steroids for itching relief

• Avoiding excessive sweating and humidity

How do I prevent Miliaria?

To minimize the risk of developing heat rash:

• Stay in air-conditioned or well-ventilated spaces during heatwaves or high humidity

• Wear lightweight, loose-fitting clothing, preferably made of natural fibers

• Shower with cool water after sweating heavily

• Refrain from applying thick creams or ointments that might block sweat ducts
