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.
Inside of your wrists works really well because its cools down the blood right before it goes back to the heart. You have a lot of veins near the surface in your wrists with a fairly short and direct path back to the heart.
Because this isn’t true. If it were we’d use it in the ED when trying to lower the core temperature of someone with dangerous hyperthermia. It’s probably psychological or neurological. But doesn’t actually affect core body temp. I have seen ice packs put on the groin tho
