Heat Rash
Heat rash, sometimes called miliaria, often happens when people sweat a lot. It is frequently seen in humid and hot weather like summer. Based on the depth of sweat trapped in the skin, heat rash has several types.
Miliaria crystalline is the mildest type characterized by tiny and fluid-filled bumps on the skin. It appears when sweat blocks the opening of the sweat ducts.
Miliaria Rubra (prickly heat) is trigged by blockage of the eccrine sweat gland. The eccrine sweat gland locates deeper than sweat pores, so miliaria rubra is more severe than miliaria crystalline. Its symptoms include small blister-like bumps along with stinging pain and itchiness. Occasionally, miliaria rubra progresses to miliaria pustulosa, where inflamed bumps fill with pus.
A rare variant of miliaria is miliaria profunda. When the sweat leaks from sweat glands to the dermis, firm and painful bumps appear on the skin as a result of obstruction. [5]
