Quizplus · Accepted Answer

Olfactory fatigue, also known as olfactory adaptation, is a real phenomenon where the receptors in the nose become less sensitive to a particular odor over time, leading to a decreased perception of the odor. This is an adaptive response to persistent or constant exposure to an odor, allowing us to focus more on new or changing scents in the environment.
