Are humans air cooled?

Are humans air cooled, because of... I guess breath, and airflow over the skin?

Water cooled, because of sweat and exhaled water vapor?

Cooled by vital fluids, like certain air cooled engines are really cooled by circulating engine oil (because our circulatory system dilates to dispel extra heat)?

Some humans are much more cool than others.

Exhibit A:

Exhibit B:

Fuck, these are some cool as fuck humans!

Air- and liquid-cooled. Air movement over skin, glands expelling sweat, cooled blood from extremities and from cool air in the lungs, and of course cool air in the lungs, as touched on.

But if you had to choose only one, which would you classify humans as? You know, for science.

Damn, you got me there

Liquid-cooled, then, because even liquid-cooled engines (and electronics) have air-cooled aspects just due to design and physics.

The skin itself is a radiator. We wear clothes to reduce its effectiveness.

Your body warms air before it hits your lungs, so breathing doesn’t really help cool you off if you’re overheating. If you’re body is overheating then the air around you is most likely hotter than your internal temperature (98.6F). That’s why people don’t pant. Other animals pant because they have very wet noses and mouths, so they get some cooling effect from evaporative cooling which they don’t get on account of not having sweat glands.

Liquid cooled. Our internal temperature is 98.6F. If you’re in need of cooling, then the air around you is most likely hotter than your internal temperature. The only reason air cools us is because we sweat. Our body heats up the sweat and it evaporates, taking the heat away with it (evaporative cooling). A breeze make you feel cooler only because it helps the sweat evaporate off your skin.

Blood plays a role in cooling as well. Certain blood vessels will dilate in order to shunt heat away from your core in order to help cool off. But again, without sweat it really wouldn’t work as the air around you will usually be hotter than your internal temperature if you’re in need of cooling.

And to keep bystanders from throwing up.

Our temperature is regulated using liquids, however there are aspects of air cooling in mammals, we just don’t use them as much.

If we had fur; I’d say our temperature would be dictated by the air around us, but since we don’t have much I think we’re liquid cooled.

Like others here, I’d liken the body to a radiator with liquid temperature regulation. I think even the old air-cooled engines in 911s still used oil for temperature regulation (to a point) but I know basically nothing about air-cooled engines.

If we were strictly air-cooled, I’d imagine that the more corpulent demographics would have long since expired due to excess insulation and lack of movement to keep airflow from cooling their bodies (although I guess A/C would work). Even the non-corpulent like myself would have passed since I’m so goddamn lazy, although the ethanol solution top-ups every weekend could help to keep temps down.

Those were a weird couple of paragraphs.
