1. Oatmeal-crush it up and put about a cup in a warm bath and sit in it for about 15-20 minutes. It feels wonderful. I forgot I had Aveeno oatmeal bath and boy did that feel good.
2. Baking soda-put a fair amount in your tub (1/4 cup) of warm water let dissolve. Sit in your tub for about 15-20 minutes. Let the skin air dry it will feel a lot better.
3. Oddly enough Ice Cubes applied directly to the heat rash will reduce swelling.
My favourite standby once the skin starts to dry out is Noxzema will keep it moist and a good antibiotic cream to help it heal further.
I plan on picking up this tool that my neighbor doused me with when she picked me up from my son's graduation Wal-mart has a motorized water bottle fan sprayer that is a great idea.
Hope this helps, keep cool and don't do what I did.
