natural insulation
Body's heat retention
Natural insulation refers to materials from plant, animal, or mineral sources used to reduce heat transfer in buildings—wool, cotton, cork, straw, or cellulose.
The term also describes insulation provided by nature itself: The thick forest canopy provides natural insulation from the summer heat.
Fat serves as natural insulation in marine mammals.
