"internal heat"?

[visceral]

How come under certain conditions like if you're hyperactive or out walking in the cold, your skin can be cold on the surface but you still feel overheated?

 

Is it just that the blood withdraws from the skin?

[Mokele]

Pretty much, yeah.

There's a condition where people suffering from hypothermia feel too hot, so they take off their clothes and freeze to death even faster.

 

Paradoxical undressing

No these is different from hypothermia . i think we need to relate it with transpiration . As in case of plants , transpiration results outer surface little cooler but internal temp. remain same . Same observed in humans when irritating sweat irritate .

More specifically, your body's "temperature sense" is most strongly tied to your core body temperature - your limbs aren't as vital to keep warm as your organs, after all. So if you've been running, which generates a lot of heat, you'll feel warm and sweat. If it's a cold day, the sweat will evaporate rapidly, making your skin cold, while your core still hasn't dropped to a low enough temperature yet to stop the sweating and feeling of warmth.
