ELI5: Why does a rug feel warmer than a tile floor when they are at the same temperature?
gpt
Because the rug (and especially all the gaps of air inside of it) transfer heat much slower than the ceramic tile does. The result is that when you are standing on the tile the heat quickly leeches out of your foot and spread out into the whole tile. On the other hand when you stand on the rug your body can quickly warm up the particular bit of rug you are standing on (since the heat can’t spread out as fast through all the air/fabric pockets) so it feels warmer.

This also works the other way too, and is why a hot piece of fabric out of the dryer can be comforting, but a piece of metal at the same temperature can be painful to touch.
