“A fragrance is like a cat burglar in your brain, it has the key with which to pick the lock and unleash your memories.” – Roja Dove
All our senses give us a window onto the world, but the sense of smell is different. Looking at old photographs can evoke flashbacks, just as hearing a long-forgotten song can. However, smells have a uniquely powerful way of piercing straight to the core—the place we keep our recollections—like an arrow shot to the centre of memory lane.
Most people have smell ‘triggers’—aromas which, as soon as they are sensed, bring a particular memory flooding back. These triggers are deeply personal and unique to each individual.
For me, it’s the smell of freshly laid tar. As a child, I likely hadn’t experienced it before. Now, decades later, one sniff takes me straight back to a warm summer day, surrounded by the sound of machinery and a sense of happiness. That memory makes it a pleasant scent to me.
How are emotions and memories triggered by smell?
The answer lies in how the brain is organised. When scent particles enter the nose, they are processed by the olfactory bulb, which has direct connections to the limbic system—the area responsible for emotion and memory. Unlike other senses such as sight or sound, smell takes a direct path, making it uniquely powerful.
Scents can have a dramatic effect on well-being. They have been shown to positively influence stress, sleep, confidence, and even physical and mental performance. Choosing the right scent at the right time can enhance daily life in meaningful ways.
A list of fragrances and their emotional effects:
-

Finally, a brief note on perception:
When you smell a flower, like a rose, it’s easy to assume the scent exists within the plant itself. In reality, the brain creates the perception of smell. Scents, like sounds and colours, are interpretations formed by the brain to help us understand and navigate the world.
