Avoid heat and clean the affected area
As soon as you witness heat rashes developing on some parts of your body, you should immediately get out of the heat and find some shade or an air conditioned room. You should dry the area softly and expose it to air. You can now clean the affected area with a mild cleanser or a non-deodorant soap.
Use a cotton towel
Now grab a cotton towel, rinse and pat dry the damaged skin. However, you should use the towel very softly otherwise you will end up irritating your skin even further.
Apply calamine lotion
Once the affected area has sufficiently dried up, apply calamine lotion on the rash to get rid of or minimise the itching. If calamine lotion is not available, you can use one percent of hydrocortisone, a non-ointment cream or any other lotion which contains dimethicone like Cetaphil Moisturizing Lotion or Moisturel. While applying the lotion or a cream, you need to follow the instructions on the product.
Take an oatmeal or baking soda bath
If you are really struggling with itching, you should take an oatmeal or baking soda bath, which should help you feel comfortable. Grind a cup of dry oatmeal in a blender and add that to the bath water. If oatmeal is not available, you may dissolve three tablespoons of baking soda in the bath water. It is recommended that you soak for about 20 minutes and rinse everything off.
Wear lose clothing
While suffering from heat rashes, you must wear lose clothing in order to avoid worsening the situation. Natural fibres like polypropylene and cotton are recommended by the experts in such a scenario.
