heat retention
Keeping warmth inside
Heat retention is the ability of a material, object, or system to hold thermal energy rather than releasing it quickly.
Materials with good heat retention—like cast iron or ceramic—stay warm long after the heat source is removed: Cast iron pans are prized for their heat retention.
The concept applies to cooking, building insulation, and body temperature regulation.
