What is the Heat Rash or Prickly Heat?

Heat rash or prickly heat is a skin condition that troubles both children and adults. It occurs due to clogged sweat glands. The baby’s skin gets warmer and then sweat is released. There will be no skin rash if sweat flows out of the skin. Tiny blisters can appear on the baby’s skin if sweat gets trapped into the skin.

It is a discomforting situation for babies. Most newborns cry when they get skin rashes. You can choose different treatments to cure this skin condition and comfort your baby. Let’s learn more about prickly heat treatment.

Why Do Babies Get Heat Rashes?

Hot weather is the main culprit behind the prickly heat issue. It worsens the situation when accompanied by humidity. Skin temperature increases when humidity levels increase in the atmosphere. The baby’s body sweats to cool down the skin temperature.

When it is quite hot and humid out there, the baby’s body will release more sweat to control the body temperature. This action overwhelms your child’s sweat glands and they get clogged.

Sweat gets trapped underneath the skin and it tries to escape through the thin layer of skin. Consequently, tiny red blisters appear on the skin, which we call heat rashes. This issue mostly troubles babies during the summer season. However, babies can get heat rashes any time of the year.

The baby may experience this issue when the room temperature is hotter than usual. Other things that may trigger this skin reaction are:

  • A baby can get heat rashes due to wearing too many hot clothes. He won’t face the risk of skin rashes if his clothing is appropriate according to the weather.
  • Since an infant’s body can’t regulate temperature effectively, he might get heat rashes whenever the temperature is hotter. You should condition his room temperature to prevent this problem.
  • Your baby’s skin folds can trap heat and cause skin rashes.

You can easily control the temperature in the baby’s room to protect him against heat rashes. Constantly monitor the room temperature to avoid both cold and heat rashes.
