Almond
Dear Almond: Actually, it disappears faster when it’s warm — but you’re not crazy if you think it’s easier to get away with smoking outside or in a garage when it’s cold out. Odor molecules move more slowly as the air gets colder, so your nose doesn’t pick up as much activity during the winter. (This is also why the smell of garbage or barbecue seems to float through the air so easily in the summer.) On top of that, studies conducted at the Monell Chemical Senses Center in Philadelphia discovered that olfactory receptors in our nostrils essentially bury themselves deeper when the air gets colder.
