Heat rash affects patients of all ages. It may be more common among infants and toddlers, but children, teenagers, and even adults can get it too. Heat rash happens when pores get blocked due to trapped perspiration. They can cause blisters or deep red bumps, depending on their severity. Heat rash isn’t a serious medical condition and can be treated with at-home care.

Heat Rash Symptoms
Heat rash primarily shows up where the skin folds, so elbows, armpits, and knees. It can also happen where tighter clothing causes friction. In infants, heat rash may also show up on the neck, shoulders, and chest.
Symptoms depend on how severe the rash is. Mild cases often cause small fluid-filled blisters that break easily. More severe cases occur deeper in the skin and cause red bumps, itching, and prickling at the skin.
The most severe case of heat rash causes firm bumps that look like goosebumps. This affects an even deeper layer of skin. In some cases and at any stage, the bump can become filled with pus and inflamed.
Causes & Risk Factors
When sweat becomes trapped in the skin and pore ducts become clogged, that is when heat rash occurs. Living in tropical climates, exercising, and overheating in general are all the most common causes of heat rash.
An infant’s pore ducts are not properly developed, so in the first few weeks of life, an infant can experience heat rash. This is especially common if they have a fever, are in an incubator, or are dressed too warmly.
Treating Heat Rash
Doctors do not need to run any tests to diagnose heat rash. They can simply determine if a patient has it by looking at it. Avoiding overheating is the most effective way to treat heat rash.
Calamine lotions or a topical steroid can be prescribed to help treat more severe cases. Using non-drying soap while bathing can also help to keep the skin moisturized.
Preventing heat rash can be simple. In the summer, wear loose-fitting clothing that does not stick to the skin. Do not wear more layers than you need. Keep your bedroom and sleeping area cool and well-ventilated. Lastly, stay in an air-conditioned room or in the shade during the summer.
