Heat Rash
When your skin has been irritated by the heat and you develope a heat rash, the first order of business is to cool down. If you can, spend as much time as you can in an air conditioned environment. Take a cool bath or try these other remedies for heat rash:
Pack it with Ice
Anything that cools the temperature of your skin will reduce the itching and swelling of heat rash. So if you don’t have time for a bath, but an ice pack or a cool compress on the heat rash for 10 minutes every 4 to 6 hours.
Add the Magic Powder
Sometimes it seems as if baking soda is good for just about anything, an it’s certainly good for relieving heat rash. Soak in a tub to which you’ve added a few tablespoons of the powder. It will ease the itching and make you feel more comfortable while the rash heals. You can also add fine-ground oatmeal, which is sold under brand names such as Aveeno.
Apply baking soda or cornstarch directly to the heat rash site to absorb moisture and sweat. Some say cornstarch is better because it is softer on the skin. Reapply every few hours, rinsing and drying the skin beforehand.
Slather to Soothe
The sticky gel of the aloe vera leaf has long been used to relieve itching and promote healing. Apply the gel to the affected skin two or three times a day, washing the skin before each application. Aloe Vera gel is sold at your local pharmacy (over the counter).
Apply calamine lotion. A traditional home remedy for poison ivy, the pink stuff can also ease the itching and irritation of heat rash.
