Prickly heat, ugh

Any other Pnetters familiar with it? I always thought it happened in hot AND humid climates, but since moving to the increasingly desertified SW, I find that it only needs the “hot” part if someone routinely plays or works outdoors.

I’m sure that neoprene, lycra, and other snug synthetics don’t help. It’s gotten so that now even loose-fitting clothes don’t prevent it.

Advice? Going naked is not an option, not that sunburn or skin cancer would be an acceptable alternative.
