Smells <—> Memory
Smells can often trigger and be associated with one’s personal memories. Why? Science. The anatomy of our body and organ structure allows smells to get routed through the olfactory bulb (the smell analysing region in the brain), then triggering familiar memories.
Before reaching your thalamus, smells first wind their way through other regions of your brain, including areas controlling memory and emotion. So with scents, you have all this extra processing even before you have conscious awareness of the scent.
Your body also contains far more receptors for smells (at least 1,000) than it does for other senses, like sight (four) and touch (at least four).3 What this means is you can discern between many different types of smells, even those you may not have the words to describe.
Individual perception to scents is different due to visual or audio memories one has personally experienced. Because of this, one scent may trigger pleasant memory in one and unpleasant memory in the other.
Specific scents can help in therapy using the connection between smell and memory. For eg, green apple scent can help in treating migranes, and lavendar for pain relief.
- Strengthening sense of smell
The more we exercise, the less likely we are to develop problems with smelling.
