Heat rash also known as prickly heat and miliaria isn't just for babies. Heat rash affects adults, too, especially during hot, humid weather.

Heat rash develops when blocked pores (sweat ducts) trap perspiration under your skin. Symptoms range from superficial blisters to deep, red lumps. Some forms of heat rash feel prickly or intensely itchy.

Heat rash usually clears on its own. Severe forms of heat rash may need medical care, but the best way to relieve symptoms is to cool your skin and prevent sweating.

Heat rash develops when some of your sweat ducts clog. Instead of evaporating, perspiration gets trapped beneath the skin, causing inflammation and rash.

It's not always clear why the sweat ducts become blocked, but certain factors seem to play a role, including:

  • Immature sweat ducts. A newborn's sweat ducts aren't fully developed. They can rupture more easily, trapping perspiration beneath the skin. Heat rash can develop in the first week of life, especially if the infant is being warmed in an incubator, is dressed too warmly or has a fever.
  • Tropical climates. Hot, humid weather can cause heat rash. Physical activity. Intense exercise, hard work or any activity that causes you to sweat heavily can lead to heat rash.
  • Overheating in general — dressing too warmly or sleeping under an electric blanket — can lead to heat rash.
  • Prolonged bed rest. Heat rash can also occur in people who are confined to bed for long periods, especially if they have a fever.

Adults usually develop heat rash in skin folds and where clothing causes friction. In infants, the rash is mainly found on the neck, shoulders and chest. It can also show up in the armpits, elbow creases and groin.
