How it's used
Primarily used when discussing clothing, blankets, or household items like thermoses that prevent heat loss. It focuses on the action of maintaining existing warmth rather than generating new heat. You will often hear it used as a compound noun or adjective when describing products designed for insulation.
Examples
The weather is turning cold, remember to wear an extra layer to keep warm.
Is the heat retention effect of this thermos good?

Common mistake
Do not confuse this with heating up something cold, such as using a microwave to heat food. 保暖 is specifically about maintaining a temperature that is already warm, not increasing it.
