why do you stop smelling the perfume on your clothes while a person approaching you percives its smell?
Answers
Pamela Dalton, a cognitive psychologist at Monell Chemical Senses Center, who has spent more than 20 years of her life researching scent memory and “nose blindness”, claims that the idea of your nose getting used to a particular smell is quite valid and has played an instrumental role in how humans have evolved over tens of thousands of years.
The process of smelling is pretty straightforward; when you first smell a scent, the smell receptors in your nose transmit a signal to the limbic system of your brain. There, how the smell is going to be perceived will be decided, which obviously affects how you are going to feel about the particular smell. However, as you continue to stay in the presence of that smell, your brain becomes used to the smell, and you gradually stop noticing that aroma.
Take a moment right now. Literally, stop reading this and smell your surroundings… do you smell anything unusual? Probably not, because your brain has gotten used to whatever smell is around you.
