Apply aloe vera gel two to three times per day, wash the affected areas in between applications.
Apply ice cubes to the affected areas for five to ten minutes at a time. Repeat every four to six hours.

Apply sliced cucumbers to the affected area as often as needed for relief.
Stick to natural fabrics, like cotton, and avoid synthetic clothes altogether. At the same time, wear loose-fitting clothes.
If you have developed blisters due to a severe heat rash, do not bandage or cover them. Instead, expose the rash as often as you can to fresh air. This helps the skin to heal more quickly.
Simply apply cooled Chamomile tea bags to the affected area.
Whenever you go out in the sun, try to carry an umbrella with you, to avoid the direct, harsh rays of the sun.
