Risk factors

By Mayo Clinic staff

Factors that make you more prone to heat rash include:

  • Age. Though heat rash can affect anyone, newborns are most susceptible.
  • Tropical climates. People living in the tropics are far more likely to have heat rash than are people in temperate climates.
  • Physical activity. Anything that makes you sweat profusely, especially if you're not wearing moisture-wicking clothing, can trigger heat rash.
