According to New York Magazine, we are unable to smell our own home, even when it smells like a "high school boys’ locker room," due to "nose-blindness." Reportedly, once our brain determines that the smell is non-threatening, "the receptors in your nose sort of switch off."
Is there anything you can do to “refocus” your brain, so it does pick up those environmental odors?
This phenomenon is known as sensory adaptation, and it’s something we experience most intensely with smells. “That’s not as true for any other sensory experience,” Dalton said. The closest comparison, she says, is hearing. If you’re working near a construction site, for example, you can tune out the noise after a while. “But if I ask you, ‘Do you hear that?’ you can refocus that part of your brain. That’s not so true with odor,” Dalton said.
