NASA EVA suits have liquid (water) cooling systems to avoid cooking the astronaut while outside the ISS.

I don't know how they actually work though. The only way to shed the heat is to radiate it away or to sink it into warming something else up.

Found this on Wikipedia:

In an independent space suit, the heat is ultimately transferred to a thin sheet of ice (formed by a separate feed water source). Due to the extremely low pressure in space, the heated ice sublimates directly to water vapor, which is then vented away from the suit.

The ice sublimator consists of sintered nickel plates with microscopic pores which are sized to permit the water to freeze in the plate without damaging it. When heat needs to be removed, the ice in the pores melts and the water passes through them to form a thin sheet which sublimates. When there is no need for heat to be removed, this water refreezes, sealing the plate. The rate of sublimation of the ice is directly proportional to the amount of heat needing to be removed, so the system is self-regulating and needs no moving parts. During EVA on the Moon, this system had an outlet gas temperature of 44 °F (7 °C),[1] As an example, during the Apollo 12 commander's first EVA (of 3 hrs, 44 minutes), 4.75 lb (2.15 kg) of feedwater were sublimated, and this dissipated 894.4 BTU/h (262.1 W).[2] The pores eventually get clogged through contamination and the plates need to be replaced.[3]

Though I think that's specifically for removing the astronaut's body heat.

There are glacier fed lakes when i live. You can float in incredibly cold water and if you have just the right equilibrium you can half float in freezing cold water while half getting a nice sun bath. And it IS very weird.

One spot I camped at for many years had nice sandy area that was about 200 meters out into the lake before a drop off. As it was only about a meter deep it used to warm up the top foot or so of the water when it was fairly still and you could stick your arm down into the water and actually feel the temperature drop like there was a line underneath the water.

Was great place to camp before it got overwhelmed by mosquitos

What if we spin around like a spit roast so the heat gets evenly distributed?

How fast should we spin as well?

Why can some objects exist in space without getting ripped apart like a human would. Is that what actually happens to a human anyways?

This uneven heat distribution confuses the brain and is perceived as pain. Veritasium (or maybe vsauce) did a video on it. Putting frozen and warm hotdog against the skin.

But imagine the side facing the sun is comfortable. Then it keeps warming up. And it keeps warming up. And you try to cool down, but it doesn't cool, it just stays the same temperature or keeps warming up.

the uneven heating would likely feel like being next to a fireplace

The thing about temperature is that it's not instant. Radiation from the sun heats stuff up, and that heat is absorbed by whatever the radiation hits according to its reflectivity and shape, and then lost from conduction, convection, and radiation. The characteristics of what's being heated by the sun and the environment it's in are what determine how hot it gets.

The photons would directly excite the molecules in your body.

There's convective and radiative heat, while the first one needs some medium to transmit energy (air...), the second one simply beams it onto you

Temperature is how much movement there is at the molecular or atomic level(depending on how you are measuring.

There is a lower limit, but no upper limit on how much heat can be measured.

This is the basis of the Kelvin scale and starts at absolute zero or the temperature at which all movement (energy) stops

Air is a medium. Flowing air is a decent heat exchanger, still air is bad at it

Okay, thank you. I’m not a very smart man, and had always wondered how planets can be heated by the sun but not space itself. It never occurred to me it’s because of the vacuum of space that keeps it cold.
