Why touching the cold metal?

When winter hits a metal object, it feels cold to touch a piece of wood even though their temperature is the same.

When you touch the metal you feel colder (Photo: Mathis) It is because the metal conducts heat better than wood: the heat of our hand has been transferred to the metal faster than from our hands to wood.

In other words, our hands lose heat, and the metal itself makes us feel cold.

Metal objects can easily transmit heat. The skin of our hand is the hottest place, the movement of heat will take place from the hand to the metal. That's why we feel cold when touching metal. In contrast, wood and fabrics are poor thermal conductors so they do not "absorb" the heat emitted by our hands. So they don't make us feel cold.

A similar way you will explain why touching a metal bar when it is hot feels hotter when touching a piece of wood next to it!
