Heat rashes, also known as prickly heat or miliaria, occur when sweat gets trapped in the pores of your skin. This blockage causes red, itchy, and sometimes painful bumps, often appearing in areas like the neck, back, chest, and folds of the skin.

Types of Heat Rashes

There are several types of heat rashes:

  • Miliaria Crystallina: The mildest form, causing clear, fluid-filled blisters.
  • Miliaria Rubra: The common form, causing red, itchy bumps.
  • Miliaria Pustulosa: A more severe form, where blisters become inflamed and pus-filled.
  • Miliaria Profunda: A rare form causing deep, flesh-colored lesions.

Causes of Heat Rashes

Hot and Humid Weather

High temperatures and humidity are primary culprits. When it's hot, sweat production increases, which can lead to blocked sweat glands.

Tight Clothing

Wearing tight or non-breathable clothing can trap sweat, exacerbating the issue.

Physical Activity

Intense exercise or physical labor increases sweating, which can contribute to the development of heat rashes.


Spending too much time in hot environments, such as a kitchen or a crowded room, can trigger heat rashes.
