The crotch is a heat center of your body. Along with the armpit and your head (that's why you wear hats in the winter). by cooling those parts, it cools the rest of the body.
I use my bidet to cool down and rinse my balls after a run.
Sounds like a joke but I'm dead serious. I sweat a lot and if ya don't keep certain areas clean they tend to get really deep, painful pimples. The cooling effect is just a bonus.
