Far better would be to cool the face, the palms of the hands or the bottoms the feet for the reasons that I described up until now.

The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.

ice packs delivered to the face are something that they actually use in order to dump heat quickly.
And of course, if you want to heat up for whatever reason, like you're camping or you're lost in the environment, remember these three surfaces are going to be the best way to heat your as well.
So you cool the hot stuff heading toward the core? - That's essentially what the standard operating procedure is. That you hit the arteries. - Amazing. - And the veins. Arteries and veins.
So face, hands and bottoms of feet will cool you twice as fast as putting cold packs into your armpits, your groin, or back of neck?
The cooling rate was double.
You can just get a thing of ice water or just very cold water. And I know it sounds trivially easy, but you're actually just cooling your core by putting your hands or even one hand on a relatively cold thing of water or ice. But not so cold that it constricts the vasculature there.
The Palmer cooling, which is essentially placing-- you can cool the core of the body most quickly by placing cold objects on the hands, the bottoms of the feet, or on the top of the face, because of the arrangement of vasculature.
Those three areas are your face, the palms of your hands, and the bottoms of your feet. Now the skin on your hands and on the bottoms of your feet, and to some extent on your face are called glaborous skin. And what's special about those areas of your body and the glaborous skin is that the arrangement of vasculature, of blood vessels, capillaries, and arteries that serve those regions is very different than it is elsewhere in your body.
The cooling rate was double. Wow. So face, hands, and bottoms of feet will cool you twice as fast as putting cold packs into your armpits, your groin or back of neck.
so the the best way is to dump heat core temp through your body is through your face your upper face where there's no uh hair and then also through your hands and the bottom of your feet so they developed like this uh glove and they've had this for years like this was there at Stan you put your hands in this glove and you dump Heat
