Prickly heat or heat rash is an irritating eruption of the skin due to obstruction of the sweat glands over certain areas of the body. In this condition many tin pin-head-size swellings occur in the skin, accompanied by severe itching. The areas most involved are the chest, back, waistline, armpits, and groins. Infants and overweight persons often suffer from heat rash.
Prickly heat occurs most often in hot, humid conditions, but it can also be developed in cool weather if you are overdressed. The condition usually appears a few days to a few months after exposure to a hot, humid environment. It's most common in infants. Newborns are particularly vulnerable to prickly heat because their sweat ducts are not mature, which makes it easier for the beads of moisture to be trapped.
When a baby gets hot, sweat must evaporate off the skin in order to cool her body down. If you interfere with this process by covering the skin with lots of clothing, plastic pants or even heavy moisturizers, the sweat that needs to get out becomes trapped beneath the surfaceof the skin, resulting in an itchy rash.
Prickly heat usually starts around the neck. If it is bad, it can spread down onto the chest and back and up around the ears and face, but it seldom produces any discomfort for a baby.
Prickly heat is due the sweat glands becoming blocked when the weather is hot and humid. Dead skin cells and bacteria may block the sweat glands, leading to sweat being retained and building up on the skin leading to inflammation, which causes the rash.
