Everybody’s house smells in some way.
You almost never even notice the way your own place smells. You notice the way everyone else’s place smells as soon as you walk in. There are their cats, and the soap, and the new furniture they just got. And those all add up to the way their house smells.
But you can only smell your own house after you’ve been away for a while—like, a long while. Not just a workday, but like a week.
It has to do with sensory adaptation (感觉适应). That’s the scientific way to say that you just get used to it. And it’s more pronounced for our sense of smell than for any other sense, like our hearing, for example.
Researcher Pamela Dalton at the Monell Chemical Senses Center has done a lot of work on sensory adaptation. She and her team say that adaptation means you respond (做出反应) less when a stimulus (刺激物) is repeated. So when you’re at home, the smell of your house is all around you. It never goes away. It’s not just repeated—you’re swimming in it. So you become adapted to the way it smells.
The thing with smell, though, is that you adapt to smells really quickly. After “even a few breaths” of a smell, Dalton says, you begin to acclimate to it.
You start to experience that smell as being less strong and finally take no note of it at all. That’s why you can smell your friend’s house when you walk in, but you don’t really notice it all the time you’re there.
Being able to detect (探测) smells is important. It might warn you of danger, like an approaching (接近的) tiger or something gone bad in your drinks. Or it might mean something pleasant, like that fresh bread or the blooming flowers.
Your nose can stay on the lookout for new smells that are dangerous or delicious.
It might be a simple housekeeping thing, like a dishwasher in the kitchen or towels in the bathroom that needs to be cleaned .
Then, if you still want to change the way your house smells, many things might do the trick, like a million candles, fresh fruits, or a bottle of perfume.

Clara Daly was sitting on a flight from Boston to Los Angeles when she heard a worried voice over the loudspeaker: “Does anyone on board know American Sign Language?”
Clara, 15 at the time, pressed the call button. An air hostess came by and explained the situation. “We have a passenger on the plane who’s blind and deaf,” she said. The passenger seemed to want something, but he was traveling alone and the air hostesses couldn’t understand what he needed.
Clara had been studying ASL for the past year to help blind and deaf people and she knew she’d be able to finger spell into the man’s palm (手掌). So she rose from her seat, walked toward the front of the plane, and knelt (跪下) by the seat of Tim Cook, then 64. Gently taking his hand, she signed, “How are you? Are you OK?” Cook asked for some water.
When it arrived, Clara returned to her seat. She came by again a bit later because he wanted to know the time. On her third visit, she stopped and stayed for a while.
“He didn’t need anything. He was lonely and wanted to talk,” Clara said.
So for the next hour, she talked about her family and her plans for the future. Cook told Clara how he had become blind over time and shared stories of his days as a traveling salesman. Even though he couldn’t see her, she “looked attentively at his face with such kindness,” a passenger reported.
“Clara was amazing,” an air hostess told Alaska Airlines in an interview. “You could tell Cook was very excited to have someone he could speak to, and she was such an angel.”
Cook’s reply: “Best trip I’ve ever had.”
