Why Does Metal Feel Colder Than Wood?

In winter, touching a metal doorknob often feels painfully cold, but a wooden desk in the same room doesn't feel as chilly. Interestingly, even when metal and wood are at the same temperature, metal usually feels colder. The reason lies in their different abilities to conduct heat. Metal generally conducts heat much better than wood. When your hand touches metal, heat transfers away from your hand more quickly, making your brain perceive a distinct coldness. Wood has lower thermal conductivity, so heat dissipates more slowly, making it feel less cold. This is also why a metal spoon gets hot quickly in hot soup, while wooden utensils typically don't transfer heat as fast. However, this doesn't mean the metal itself is necessarily at a lower temperature; it's just that the rate of heat exchange with our skin is different. Sometimes, the difference we feel in touch isn't entirely about how cold an object is, but how quickly heat moves.
