Ever caught a whiff of something and been transported straight back to a holiday, a childhood home or a person you haven't thought about in years? That's not your imagination. Scent has an unusually powerful connection to memory, emotion and how we experience the world around us.
Of all our senses, smell has a rather special relationship with the brain.
A familiar scent can make you feel comforted, energised, nostalgic, or suddenly transported somewhere else entirely.
Think of the smell of sunscreen and you're back on a beach. Freshly baked bread takes you into a kitchen. A particular perfume reminds you of someone before you've even consciously registered what you're smelling.
So what's going on?
Your nose has a direct line to emotion.
When you smell something, the information travels through the olfactory system to areas of the brain involved in emotion and memory, including the amygdala and hippocampus.
That's one reason smells can trigger such immediate emotional responses.
You don't necessarily think:
"That smells like my grandmother's kitchen, which reminds me of Sunday lunch..."
You simply feel something.
And that makes scent particularly interesting when we're thinking about everyday wellbeing routines.
We can use scent as a cue.
While scent isn't a magic switch for stress relief or anxiety, it can become part of a conditioned routine — a sensory reminder that tells your brain what happens next.
Think about how quickly certain sounds can put you into a particular mode.
The alarm means wake up.
Your laptop opening means work.
The school-run traffic means here we go again.
Scent can become another cue.
If you repeatedly use the same calming scent while winding down at night, for example, you're creating an association between that aroma and your bedtime routine.
Over time, the scent can become part of the ritual itself.
Try creating your own "scent anchors"
You don't need a different product for every problem. Start by choosing one moment you would like to change.
For switching off
Choose a scent you find calming and use it at the same point in your evening — perhaps when you put your phone away, change into pyjamas or make your last cup of tea.
For focus
Use the same scent whenever you sit down for concentrated work. Keep the ritual short: scent, breathe, decide what you're doing for the next 20 minutes.
For a transition
If you find yourself carrying work stress into the evening, use a familiar scent when you finish work. Step outside, breathe slowly and let the scent become your cue that work is finished.
For a moment of calm
When you notice your shoulders creeping up towards your ears, pause. Bring a scent to your pulse points, take a slow breath and simply notice how you're feeling.
There's no need to force yourself to feel different.
You're simply creating a moment to pause.
The important bit: repetition
The power isn't necessarily in finding a particular "perfect" scent.
It's in the association you build around it.
The more consistently you pair a scent with a particular activity or moment, the more meaningful that sensory cue can become.
That's why aromatherapy can be much more than simply making something smell nice.
It can become part of a ritual.
A reminder to slow down.
A cue to focus.
A signal that the day is ending.
A moment to come back to yourself.
And perhaps that's why scent is such a lovely addition to wellbeing:
It doesn't require another app, another screen or another thing to achieve.
Sometimes, you just need to stop.
Inhale.
And Reset.
