"Nose blindness," also known as olfactory fatigue or olfactory adaptation
It is the phenomenon where a person becomes less sensitive or completely unresponsive to certain smells,
It happens after being exposed to them for a prolonged period of time.
Essentially, your nose gets "used to" the smell, and you stop noticing it.
This happens because the sensory cells in your nose (specifically, olfactory receptors) become less responsive when exposed to a consistent odor over time.
It's your body's way of preventing sensory overload.
For example, if you're in a room with a strong odor, you might stop noticing the scent after a few minutes or hours, even though others can still smell it.
