The perception of temperature in materials is affected by thermal conductivity and specific heat capacity. For instance, metals feel cooler than wood at the same temperature due to their higher thermal conductivity, drawing more heat from the hand. Similarly, water feels colder than air at the same temperature because of its greater heat capacity. Blankets serve as insulators that prevent heat loss in cold environments but can raise body temperature if the ambient temperature exceeds body temperature. The ability of a blanket to cool depends on its mass and thermal interaction with the body.
When you touch objects at the same temperature, the one that feels cooler often has a higher thermal conductivity, leading to greater energy loss from your hand.
A blanket works as an insulator, slowing heat transfer. This keeps you warm in cold conditions, but can trap heat if the environment is too warm.
