Heat rash: Causes, symptoms, and treatment

Heat rash is nothing more than a red or pink rash mainly appears on your body which is covered by clothing. Mostly it happens because of the blockage and swelling of the sweat ducts. It causes itching and discomfort.

Babies get heat rashes easily but in a humid, hot climate even adults can have it. In medical terms, it is known as Miliaria. In this condition, one can witness small, pink pinpointed bumps on their face, neck or other parts of the body.

Miliaria can be classified into three types, which are as follows:

  • Miliaria Crystallina or Clear: this is the mildest of all, and in this condition, the bumps are neither painful nor itchy.
  • Miliaria Rubra or Red: One can see these on the outer skin layer though they occur deep in the skin. They are quite itchy and looks red, mainly found in babies as well as in adults.
  • Miliaria Profunda or Deep: Rarely occur and can be seen in adults. They occur only after repeated events of heat rashes.

If the weather is hot, and the clothes are warm, chances of having a heat rash are quite high in babies as well as in adults.

  • If you notice a heat rash on your baby’s skin, loosen your baby’s clothes or remove them and take your little one to a cool place.
  • Do not rub the skin with a towel. Let it dry on its own.
  • Do not use ointments or lotions in the sore areas. It may further irritate the skin.
