As we explore perfumes over the years, we tend to collect not just bottles but also fascinating details about them. Whether it’s something about ingredients, chemistry or history, those little bits of trivia add even more charm to our hobby.
Saturday Question #283:
What’s the Most Interesting Perfume Fact You’ve Learned?
It doesn’t have to be an obscure or groundbreaking fact – just something that surprised or intrigued you when you first learned it. Maybe it’s something many perfumistas learn sooner or later, but most people outside our hobby wouldn’t know.
My Answer
I recently came across something called “olfactory training” or “smell training,” which involves regularly smelling some distinct scents (e.g., rose, lemon, clove and eucalyptus) and consciously trying to identify them. Research shows that these simple exercises act like a workout for the brain, helping to keep memory and thinking skills sharper over time. Clinical trials with older participants and patients with early Alzheimer’s suggest that this kind of mental engagement can have measurable benefits.
For example, in one recent study, participants aged 60–85 in an “enriched” group were exposed to seven different pleasant scents each week, one per night, for two hours using diffusers, while a control group received only tiny amounts of the scents. After six months, the enriched group showed significantly greater improvement on a word‑list recall test, and brain scans revealed changes in a neural pathway known to decline with age.
It’s not a treatment for dementia, of course, but at least our perfume habit has an excuse for being indulgent: it’s brain exercise! Time for round two: let’s see if I can finally pick out a few notes in the latest batch of samples.
