Environmental Rash
Among the most common types of skin rashes, heat rash, also known as miliaria and prickly heat, isn't a condition that only affects babies. It affects adults, too, particularly during hot, humid weather. Heat rash develops when blocked sweat ducts, or pores, trap perspiration under the skin, resulting in the skin producing superficial blisters and deep, red lumps. Some types of heat rash feel prickly, while others may feel intensely itchy. Heat rash occurs most often in hot and humid climates, and it is most common in infants, though patients of any age can experience it. Patients who are active, newborns in incubators, and people on bed rest with fever have a high likelihood of developing heat rash.
Sweat ducts become blocked and trap sweat beneath the skin, causing inflammation and tiny, itchy bumps.
Wear loose, breathable fabrics (like cotton) and avoid heavy sweating in hot, humid environments.
Cooling the skin, calamine lotion, and mild topical steroids to reduce inflammation.
Myth: You only get heat rash in the summer. Fact: You can get it in winter if you overdress or use heavy blankets.
If the rash lasts more than a few days, worsens, or shows signs of infection like pus.
