Risk factors

By Mayo Clinic staff

Factors that make you more prone to heat rash include:

  • Being a newborn. Though heat rash can affect anyone, newborns are most susceptible.
  • Being in a tropical climate. People living in the tropics are far more likely to have heat rash than are people in temperate climates.
  • Participating in intense physical activities. Anything that makes you sweat profusely, especially if you're not wearing moisture-wicking clothing, can trigger heat rash.
