Lifestyle and home remedies

By Mayo Clinic staff
  • In hot weather, dress in loose, lightweight clothing that wicks moisture away from your skin.
  • Spend as much time as possible in air-conditioned buildings.
  • After bathing, let your skin air-dry, instead of toweling off.
  • Use calamine lotion or cool compresses to calm itchy, irritated skin.
  • Avoid using creams and ointments, which can block pores further.

If you keep your skin cool and dry, heat rash will usually clear up in seven to 10 days.
