Heat Rash in Babies (Miliaria)
Heat rash occurs when babies are overdressed or during hot weather. Sweat glands become blocked, forming small red bumps — usually on the neck, in skin folds, and on the upper body. Although harmless, they itch and make your baby fussy.
Possíveis Causas
- 1Overheating from too many layers of clothing (most common reason!)
- 2High humidity and heat in summer
- 3Immature sweat glands in newborns
- 4Synthetic clothing that doesn't wick away sweat
- 5Fever — elevated body temperature can trigger heat rash
O Que Você Pode Fazer
- Remove excess clothing — rule of thumb: one layer more than you're wearing
- Move to a cool room or use a fan (not pointed directly at baby)
- Light, airy cotton clothing
- Lukewarm bath — NO soap or bath additives
- Let affected areas air dry, no powders or creams
Quando Ir ao Médico?
- Bumps become pustular or crusted (bacterial superinfection)
- Baby has fever along with the rash
- Rash spreads and worsens despite cooling
- Baby is unusually sleepy or feeds poorly (heat stroke signs)
Notas por Faixa Etária
Newborns are most susceptible as their sweat glands are still immature. Particularly common in the first year. Well-meaning grandparent advice ('The child is cold!') often leads to overheating. The neck test reveals if your baby is too warm: if the back of the neck feels sweaty and hot, your baby is overheated. Cool hands and feet are NORMAL and not a sign of being cold.
