Olfactory fatigue, also known as odor fatigue, odor habituation, olfactory adaptation, or noseblindness, is the temporary, normal inability to distinguish a particular odor after a prolonged exposure to that airborne compound. For example, when entering a restaurant initially the odor of food is often perceived as being very strong, but after time passes the awareness of the odor normally fades to the point where the smell is not perceptible or is much weaker.
