Why do you stop smelling fragrances after a while e.g. room fresheners after you’ve been in the same room

Question

For example you open a new air freshener and you smell it and it lasts for a few days but does your nose ‘get used’ to the fragrance and you stop smelling it?

Answer 1

This goes with every sensory perception you have by the way:

1. New sensations always feel the strongest
2. If you felt the same way each time, you would be in a constant state of “oh no! What is that? Fight or flight?”
3. Ie. Jumping into a pool of cold water. If your brain did not desensitize you to this perception, you would be constantly in a state of shock.
