Heat Exhaustion in Newborns: What to Watch For This Summer

It’s no surprise that summer temperatures are on the rise! And while you’re getting hot and sweaty, so is your newborn. With fall temperatures nowhere in sight (at least here in Texas), we want to take a moment to talk about heat exhaustion in newborns. 

Today’s blog covers what to look for, when to seek help, and how to prevent your little one from getting heat exhaustion.

Heat Exhaustion Signs to Watch For in Newborns

Newborns are more susceptible to extreme heat because their bodies haven’t quite figured out how to regulate their body temperature. And because babies have a higher surface area to body mass ratio, they absorb heat exponentially faster than adults.

Here’s how to spot heat exhaustion in newborns:

• Pale skin

• Profuse sweating or nausea

• Dizziness

• Fainting 

• Weakness 

• Mild fever 

So, what causes heat exhaustion in newborns? Well, most cases are caused by dehydration from profuse sweating. As long as symptoms are mild, you can treat heat exhaustion at home by…

• Moving your baby to a cooler environment immediately

• Giving them milk or formula to hydrate

• Using a cool compress or drawing a lukewarm bath to lower body temperate

• Removing excess clothing

However, make sure to seek emergency care if your little one develops a fever, faints, or if symptoms persist for more than 2 hours. 

What is Prickly Heat?

When sweat ducts are blocked, perspiration gets stuck under the skin – causing a rash and mild irritation (aka prickly heat). 

Prickly heat in newborns is common because, as we mentioned, their bodies aren’t able to regulate temperature easily (causing them to potentially sweat excessively.) If you notice a prickly heat rash – with or without the symptoms of heat exhaustion in your newborn – focus on treating the rash by:

• Cooling down. Keep your newborn in a cooler environment and use fans and lightweight clothing to help regulate their temperature.

• Keeping skin dry. Gently pat the skin dry whenever your little one starts to sweat, but avoid vigorous rubbing.

• Taking cool baths. Draw a cool or lukewarm bath for your newborn and avoid using soap on the rash.

• Avoiding ointments or creams. Ointments, creams or lotions can further block the sweat ducts. 

• Staying hydrated. Keep up with feeding times to ensure your baby is hydrated to recover from the rash. 

  
  

Tips for Avoiding Heat Exhaustion in Newborns

Maintaining your newborn’s body temperature is vital for avoiding heat exhaustion. Here are some tips from our infant care experts:

• Frequent feedings in the warmer months keep your newborn hydrated

• Lightweight clothing allows for better airflow

• Sun protection is non-negotiable when you go outside (even if just for a minute)

• Try not to stay outside for an extended period of time

• Always have cool air and ventilation around the crib

• Make sure to fully dry them off after bath time to keep body temperature regulated.
