Heat is more than just a number on a thermometer—it’s a sensation that pulses, presses, and radiates, wrapping itself around the skin, the air, and even emotions. Whether it’s the blistering summer sun or the fire of a heated argument, hotness can be physical, emotional, or symbolic. But how do we put that feeling into words?
Metaphors give us a powerful way to describe heat in a way that resonates.
