Warmth can amplify
Hot food, sun-warmed materials and heated rooms can make some smells feel more present.
EXPLAINER
Smell & Temperature
Temperature can change volatility, intensity, airflow and what a smell feels like perceptually.
Cold can simplify
Cold outdoor air can feel sparse or clean partly because fewer odor sources dominate perception.
Temperature is also language
People describe smells as warm or cool even when they are talking about emotional or stylistic character.
Temperature descriptors in SmellBook can be perceptual metaphors unless a specific physical context is stated.
