Heat rash (miliaria) is a fine rash caused by blockage of the sweat ducts, which worsens in hot, humid weather. Because babies' sweat glands are not yet fully mature, it is very common especially in newborns and infants. In hot climates such as the summers of Gaziantep, families encounter heat rash frequently.

What Does It Look Like?

  • Pinhead-sized red bumps or tiny blisters filled with clear fluid on the neck, nape, armpits, groin, back and chest
  • Itching and a stinging sensation; restlessness in the baby

Things That Make Heat Rash Worse

Overdressing (very typical in babies dressed in layer upon layer out of fear that "the baby will get cold"), synthetic fabrics, heavy use of creams/oils, and periods of febrile illness.

How Does It Clear Up?

  • Keep the environment cool (room at 22–24°C); do not let the baby sweat
  • A single layer of thin cotton clothing is enough — the rule is one layer more than an adult, not more
  • Give a lukewarm bath and gently dry the skin; keep skin folds dry
  • Avoid greasy, heavy creams; do not use powder unless a doctor recommends it
  • Heat rash usually fades on its own within a few days

When Should You See a Doctor?

A medical exam is needed if the rash becomes infected (yellow blisters), the surrounding area turns red, fever accompanies it, or there is no improvement within 3–4 days; it must be distinguished from other rashes that look similar.
