So having a cold shower has no effect on core temp? What about a cold bath? What about being in the sea after an accident at the higher latitudes??

Also I think you will find that returning your skin to a normal temperature after chilling in in any way (water, aircon, etc) temporarily decreases core temperature after which you expend energy to return it to normal.

We may have had thousands (if not millions) of years to evolve solutions to heat conservation but they aren't perfect, or people would never die in freezing water or conditions.

If your core temperature drops, it's probably because you're losing heat faster than you can generate it. That kind of points to how effective this could be in the limit of being nearly fatal - If you can lose more heat than your body can produce, you're surely doing a pretty good job of burning calories!

Yes, I agree we're far from perfect at conserving heat. We're optimized for other conflicting purposes instead. We don't even have fur.
