A metal door handle and the wooden door are in the same room all night. In the morning the handle feels much colder, even though a thermometer would probably give a similar temperature for both. My guess is metal transfers heat away from my hand faster, so my skin interprets that as ‘colder.’ Is that essentially the whole story? And would the reverse happen if both materials were warmer than my hand?

And the reverse works too. If both objects are warmer than your hand, the metal can feel hotter faster because it pushes heat into you more quickly.

The key detail is not the thermometer reading but the rate of heat flow. Wood slows that transfer, metal speeds it up.

That’s why a metal bench in the sun can be miserable and a wooden one nearby feels less intense, even when they’ve both baked all afternoon.
