I had a conversation with some of the folks that I work with yesterday. During the course of this conversation one of my employees mentioned that he had a runny nose earlier and had used peppermint oil dabbed under his nose to clear out his sinuses. While this worked, he also made the mistake of sniffing some up his nostril which immediately caused an uncomfortable burning sensation. As it turns out, you can also dab a little peppermint oil onto the roof of your mouth for the same effect. Of course, this results in the concentrated essence of peppermint boring a hole through your soft palate and directly into your brain. Next thing you know you’re running around the office, clutching your skull and screaming “My medulla oblongata is on fire!”
But what it did get me thinking about is how it is always said that the sense of smell is one of the major triggers for memory. I wonder if this is true for everyone or just certain people, or perhaps the in order for the memory trigger to occur, the scent must be attached to a particularly powerful or vivid memory. Maybe the smell of cotton candy and popcorn brings back the memory of your sixth grade crush that you finally built up the courage to kiss at the county fair. The smell of baking cookies allows you to recall happy, peaceful times spent in your grandmother’s kitchen. The smell of wet asphalt and exhaust reminds you of the weird guy in the trench coat and the windowless white van that always wanted to give you a puppy.
Of course, scientists will tell you that most new scents are experienced while we are children, which explains why most scent-associated memories are from childhood. I am certain I smelled a ton of things when I was a kid, but those scents now do not act as particularly strong memory triggers for me, at least not memories where I am flooded by imagery of my past. More often than not certain scents will invoke an emotional response or invoke a certain mood. For instance, the smell of roasting green chilies will always bring my back to growing up in New Mexico.
Interestingly enough, the human sense of smell is not particularly effective in differentiating scents if we cannot see the object making the smell.
Is that a dead possum or a nice aged Brie?
Let’s face it, we’re a long way away from having the police hook us up to leashes and having us track an escaped convict through the woods.
Of course, the sense of smell has been harnessed by marketers and advertisers to draw us in. Malls smell like fresh baked cookies, realtors will have cookies of pies sitting on the counter of the house they want to sell, all to make you feel more at home and comfortable. Be honest with yourself. You’re way more likely to buy a house if it smells like a fresh-from-the-oven apple pie than one that smells like dead-hooker-rotting-under-the-sleeper-sofa. There’s a reason that scent never took off at the perfume counter at Macy’s.
My one challenge with scent and memory being inexorably linked (and they are. I don’t argue with scientists since the Great Nerd Uprising of ‘83, also known as Nerdageddon.) is how does my mind determine which memory should be linked to a particular scent. Does there come a point where I have smelled a certain odor so many times in so many different context’s that my brains just stops linking memories to it?
Of course, we all have our favorite smells, things that will always hold a special place in our nasal passage.
1. Frying Bacon – Always reminds me of Sunday breakfast as a kid, after church, when mom would fry up bacon and eggs for the family, usually before we’d take a trip up to the mountains to hike or pick raspberries.
2. Fresh Ground Coffee – No particular memory here. Just love the smell of fresh ground coffee.
3. The smell of the desert after a rain storm – Wet sage, damp earth. It just smells clean and fresh and wild.
4. Anything baking – Bread, cake, cookies. Baked goods baking automatically smell delicious.
5. Roasting green chilies – A reminder of life growing up in New Mexico.
There are other smells, of course, that are delightful but do not harbor a particularly strong emotional response for me, at least on a conscious level. Perhaps when I smell the cinnamon-imbued pine cones at the local grocery, I love the smell so much because on a subconscious level it reminds me of something, of a happier time, perhaps, when life was full of less stress, less responsibility, and more time to play and be free.
A time when pine cones were made out of cinnamon.
