OIfactory Fatigue is a name for the common experience of losing sensitivity to odors after prolonged exposure. If you work around the same odors all day, your body will adapt and the smell will weaken over time. Eventually, you will no longer be able to recognize the smell because you are experiencing Olfactory Fatigue. Olfactory Fatigue will go away if you have extended time away from a smell, but will soon after you return to it, come back.
Olfactory Fatigue is a sensory adaptation. It enables your body to adapt to prolonged exposure to smells so that your nervous systems doesn’t become overloaded, as it needs to be ready to respond to new smells. The human body and our senses work in curious ways. If we have an alert of something dangerous to our health for a while, our body decides to shut it off if we choose to do nothing about it. We begin to tolerate the pain/ occurrence as if it is not even there.
