EXPLAINER
Smell & Season
Season changes temperature, plants, food, clothing, ventilation and routine—so the smell world changes with it.
Summer
Heat intensifies food, skin products, vegetation, asphalt and coastal experiences.
Autumn and winter
Dry leaves, smoke, spices, indoor fabrics and cold-air experiences become more salient.
Seasonal associations depend on geography, climate and culture; they are not globally universal.
