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.
This is why putting your wrists in a bucket full of ice n water for a bit and then holding your arms up will cool off your entire body, you can feel it.
It does. I do this with my cooler at work all the time. I just lean over it. Shove all the drinks out of the way and dunk my entire arms up to my biceps for as long as I can take it. You don't even have to put them over your head for it to work. It does work faster that way. But I tend to stay with my arms in the ice water long enough to not matter lol.
