Why cooking pots are provided with wooden or plastic handles

Metal cooking pots and pans often have wooden handles. Wood has a higher specific heat than metal, so it takes more energy to heat a wooden handle than a metal handle. As a result, a wooden handle would heat up more slowly and be less likely to burn your hand when you touch it.
