Medically Reviewed by Renee A. Alli, MD on November 05, 2019

Heat rash in young children can look uncomfortable, but it's usually not serious.

Call Doctor If:

  • The heat rash is still visible after 3 or 4 days.
  • The rash gets worse.
  • The rash causes serious itching.
  • The rash oozes pus or swells.
  • The rash is red or purple or looks like bruises.
  • The rash is tender.
  • The child has a fever.

1. Treat Symptoms

  • Give your child a cool bath.
  • Put your child in an air conditioned room, or position a fan so that a gentle breeze blows over them.
  • Avoid creams or ointments that may irritate the skin.

2. Dress for the Heat

  • Dress your child in soft, lightweight, cotton clothing to help absorb moisture.

3. Keep Your Child Hydrated

  • Make sure your child is getting enough fluids when the weather is hot.
  • Your child should hydrate before and during prolonged outdoor activity.
  • Your child should take frequent breaks from intense exercise when the weather is hot.
