Do they literally just disappear or what happens to them
In: Chemistry
Smells are entirely in your brain. (According to *The Body: A Guide for Occupants* by Bill Bryson, which I am currently reading.)
A smell is your brain’s reaction to the affect of airborne molecules on the nerves in your nose.
When you can’t smell the smell any longer, it’s because your brain has become habituated to that smell and ignores it. Chances are, though, that the molecules are still around.
So… your house still smells, just like it did when you first returned home. You just can’t smell it anymore. But someone new coming into your house will still smell that smell until they, in turn, become habituated to it.
