Prickly Heat

Prickly heat or miliaria rubra is the most common type of heat rash. In this form of heat rash, the sweat duct becomes red and inflamed, and may cause a 'prickling' or stinging sensation. This type of heat rash may also cause mild hitching.

The inflamed sweat ducts look like small bumps with a red halo around them and can usually be found grouped together under a child's clothing and inside the folds of his skin, such as his neck, armpits, and groin. Infants who wear a hat may also get a heat rash on their forehead and scalp.

Miliaria Crystallina

Just like prickly heat, this type of heat rash occurs when the sweat ducts become blocked and rupture. These sweat ducts are closer to the skin surface though and don't get inflamed, leading to the classic appearance of small clear vesicles on the child's skin, without any redness or other symptoms, typically on their neck, head, or upper chest.

Preventing Heat Rash

Most methods of preventing heat rash have the goal of not allowing your child to get overheated and include:

• dressing your child in weather appropriate, loose fitting clothing, so that he doesn't get overheated.
• avoiding excessive heat and humidity when possible.
• avoiding occlusive ointments, including moisturizers, or oil based products on a child's skin, which can also block the sweat ducts.
