From the Merck Website:
The condition is controlled by keeping the skin cool and dry. Use of powders and antiperspirants often helps. Conditions that increase sweating should be avoided, thus an air-conditioned environment is ideal.
What Causes Prickly Heat?
Prickly heat results when sweat glands are blocked and ruptured, and sweat is trapped below the skin.
Once the rash develops, corticosteroid creams or lotions are used, sometimes with a bit of menthol added. However, these topical treatments are not as effective as keeping the skin cool and dry.
Thanks to all. See the wise guys suggest beer, vodka and sex and the ladies (and a few guys) have more sensible but less fun suggestions. Thanks - it really is creepy.
