This is why a piece of metal feels cooler than a piece of plastic or wood at the same exact temperature - the metal conducts heat away from the higher body temperature than a good insulator does. |
So in warm weather, it's not just the temperature that matters for comfort. The humidity and wind speed also factor into it. When humidity is high, sweat evaporation is less effective at cooling us off than in a "dry heat" with low humidity. | So in warm weather, it's not just the temperature that matters for comfort.
