Week Eleven Medical Issues - Heat Rash
Parents are often used to the fact that their babies are going to have less than perfect skin by now, what with baby acne, diaper rashes, cradle cap, etc.

They aren't always prepared for the first time that their baby gets a heat rash though, as they often confuse heat rashes with an allergy, infection, or other baby skin rashes.

Heat Rash Symptoms

With a typical heat rash, a baby's sweat ducts become red and inflamed, and may cause a "prickling" or stinging sensation, which may lead to mild itching.

The inflamed sweat ducts look like small bumps with a red halo around them and can usually be found grouped together under a baby's clothing and inside the folds of her skin. Affected areas typically include a baby's neck, armpits, and groin. Babies who wear a hat may also get a heat rash on their forehead and scalp.

Preventing Heat Rash

Most methods of preventing heat rash have the goal of not allowing your baby to get overheated and include:
  • dressing your baby in weather appropriate, loose fitting clothing, so that she doesn't get overheated.
  • avoiding excessive heat and humidity when possible.
  • avoiding thick occlusive ointments, including moisturizers, or oil based products on a baby's skin, which can block the sweat ducts.

Heat Rash Treatments

Although heat rash usually goes away on its own in a few days, some children do require treatment, which can include:
  • removing the child from the triggering environment, such as dressing in less clothing, moving inside to a cooler, air-conditioned environment
  • mild strength topical steroids, although these usually aren't needed
  • calamine lotion
  • compresses with cool water
  • antibiotics for secondary infections
