Heat Rash Babies

Most bumps and blotches on a newborn baby are harmless and clear up by themselves. A rash is any skin bumps or blotches. The rash can be red, skin-colored, or slightly lighter or darker than skin color. By far the most common skin problem in infants is diaper rash.

Another common skin problem that occurs with babies is heat rash. With heat rash babies pores of the sweat glands become blocked. This generally happens when the weather is hot or humid. As the infant sweats little red bumps and possibly tiny blisters form because the blocked glands cannot clear the sweat. When the weather is hot or humid, the infant sweats, but because of the blockage of the sweat glands, this sweat is held within the skin and forms little red bumps, or occasionally small blisters in young infants.

Some helpful suggestions to avoid heat rash are during the hot season dress your baby in light-weight, soft, cotton clothing. Cotton is very absorbent and keeps moisture away from the baby’s skin. If air conditioning is not available a fan may help evaporate moisture and cool the infant. Place the fan far enough away that there is only a gentle breeze drifting over the infant. Avoid the use of powders, creams, and ointments. Baby powders don’t improve or prevent heat rash. Creams and ointments tend to keep the skin warmer and block the pores. Most often, heat rash goes away on its own. Severe forms of heat rash may need medical care, but the best way to relieve symptoms is to cool your skin and prevent sweating.

Heat rash is also known as prickly heat and miliaria and it does not just affect babies. Though it’s most common in infants, heat rash affects up to a third of adults living in tropical climates and can bother anyone during hot, humid weather. Heat rash develops when your sweat ducts become blocked and perspiration is trapped under your skin. Symptoms range from superficial blisters to deep, red lumps. Some forms of heat rash can be intensely itchy or prickly.

Heat rash usually heals on its own and doesn’t require medical care. See your doctor if you or your child has symptoms that last longer than three or four days, the rash seems to be getting worse or there are signs of infection such as increased pain, swelling, redness or warmth around the affected area or pus draining from the sores. Swollen lymph nodes in the armpit, neck or groin and fever or chills are all warning signs of a more serious condition.
