eli5: How come when we sit down where someone else has been sitting, it feels warm. Yet when we sit down where we have been sitting already, you don’t feel anything.

Potentially dumb question but I’ve been curious about this for a while.

Your ass is already the same temperature as the seat if you sat there previously.

When someone else was sitting there before you, your ass is less warmer than the seat so your ass feels the temperature difference, even though it’s a bad thermometer.

If two people sit on a bench and exchange their ass spots, their asses won’t feel the difference in bench warmth. Hope it helps.

our body is stupid it doesn’t know whAt the real temperature is which is why when daddy takes drugs in the summers he sometimes thinks he’s freezing his ass off

Your ass is not a thermometer. It senses changes, not real absolute values.

Here is an experiment anyone can do. 3 buckets. (1) gets hot water on your tap. (2) gets normal temp. (3) gets cold water plus some ice if youre feeling spicy.

Dunk your hands in 1 and 3 for a minute. Then duck both into 2 and see how the temperature feels. Same temperature, different change.

Anyway, your ass is the same.

New warm seat feels warm because your ass cold and not used to the seat.

Because if we were just sitting there, we already know what the temperature is and are already acclimated to it.

When we sit where someone else is, however, we do not expect that and it’s the fact that it does not match what we were expected to feel that gets our attention.

It has nothing to do with the question who has sat there before, if it was yourself or somebody else. The point is the temperature difference between your ass and the seat. If they have about the same temperature you don’t feel anything, if the seat is colder than your ass it feels cold, if it’s warmer than your ass it feels warm. Regardless of who caused the ‘seat temperature’.
