What are the suitable remedies for prickly heat rash?

Fact Checked

Prickly heat rash or miliaria most often develops on infants whose sweat glands are easily blocked but can also occur in older children and even adults. Take note that prickly heat rash develops once the sweat glands that are responsible for cooling the skin rupture from being clogged up and the sweat seeps into the tissues, resulting to rashes.

The two forms of miliaria most often occur frequently – miliaria crystallina and miliaria rubra. When it comes to miliaria crystallina, it leads to the production of small-sized blisters that do not cause the reddening of the skin. As for miliaria rubra, it causes red-colored, itchy bumps. There are simple remedies that usually treat prickly heat rashes effectively without requiring medical care but in some cases, a secondary infection or severe discomfort would require medical attention as soon as possible.
