Whenever someone comes back from a walk outside on a crisp day, they have an odor that’s distinctive of outside. My nose is not the best, but I’d say somewhat metallic. What is causing that smell?

All of these “air out your house more” comments are annoying, I know exactly what you’re talking about. Whenever someone comes in from outside, particularly when it’s cold, they have that smell. I wonder if its something to do with temperature affecting what smells are most prominent?
