I bought a lotion on vacation.
Nothing fancy. Just something that smelled like sunshine and calm and not having 47 things to do before 8 a.m.
I used it every single day while we were away. After the shower. Before dinner. Sometimes just because.
Now it sits in my bathroom at home and every once in a while, I take it out and use it after a shower. Instantly I’m back there, our beach house we rent each year that holds many amazing memories.
The slower mornings.
The sunshine and waves.
The version of me that wasn’t juggling schedules and snack bags and notifications.
It’s wild how a simple scent can do that.
But it turns out… it’s not random.
It’s science.
Why Smells Trigger Memories and Emotions
There’s actually research behind this.
Our sense of smell is directly connected to two powerful parts of the brain:
- The amygdala (which processes emotion)
- The hippocampus (which processes memory)
Unlike sight or sound, smells don’t take a long route through the brain’s filtering system. They go straight to the emotional and memory centers.
That’s why scent memories often feel:
- More vivid
- More emotional
- Older and deeply rooted
- Almost physical
Scientists have studied how smells connect directly to the brain’s emotional and memory centers, which is why scent memories can be so powerful (Cleveland Clinic).
When a Spray Can Take You Back 20 Years
Years ago, I came across an old stash of sprays from my high school and college years old favorites from Bath & Body Works and Victoria’s Secret.
I opened one.
And just like that I wasn’t in my bathroom as a mom with two kids and a packed calendar.
I was 17 again.
Or 20.
Or getting ready with friends before going out.
The emotions weren’t just memories. They were feelings. The excitement. The insecurity. The freedom. The simplicity of that season of life.
It honestly caught me off guard.
I didn’t expect a body spray to unlock that much.
But scent doesn’t ask permission. It just opens the door.
The Most Powerful Bottle on My Shelf
There’s another bottle I keep.
My dad’s cologne.
He passed away 14 years ago.
And every once in a while, I’ll open it and breathe it in.
And for a second he’s there.
Not physically, of course. But the feeling is immediate. The comfort. The familiarity. The safety.
And yes the emotions come with it. Sometimes it can hit me harder than others and I don’t smell it often, maybe once a year.
That’s the thing about scent.
It doesn’t just remind you.
It reconnects you.
Because smell is wired straight into emotion, it can pull grief, love, nostalgia, and warmth to the surface before you even have time to brace yourself.
Sometimes it makes me smile.
Sometimes it makes me cry.
But it always reminds me that memory lives deeper than we think.
Why Scent Feels So Emotional
Smell developed early in human evolution. It helped humans detect danger, food, and safety.
So our brains wired scent directly into survival systems.
Which means when you smell something familiar, your brain doesn’t just think about it.
It feels it.
That’s why:
- A perfume can instantly remind you of a person.
- Sunscreen smells like summer before you see the beach.
- A hospital scent can make your stomach tighten.
- A loved one’s cologne can bring you to tears.
Smell bypasses logic.
It goes straight to the heart.
How to Use Scent to Trigger Positive Feelings
This year on vacation I intentionally created a scent anchor with the lotion. I purchased it in the gift shop in the beach town we stay in. I used it everyday.
Every day on vacation, my brain linked that smell to:
- Rest
- Slower mornings
- Laughter
- No pressure
Now I use it at home when I feel down and my brain recognizes it.
“Oh. We’ve felt calm before.”
Recently I wore a fall scent I bought around Halloween “Evil Queen” from Bath & Body Works and my daughter immediately said, “You smell like fall. I like that scent.”
It made me realize something. The same way scents take me back, they’re quietly becoming part of her memories too. That prompted me to share this with others.
How You Can Use Scent in Your Daily Life
You don’t need a special occasion to start or wait until vacation. However I do fully recommend when you do take that vacation, you select a vacation scent.
For now try this:
Choose one scent for one purpose.
- Use one lotion only before bed to signal rest.
- Light one candle only during journaling or quiet time.
- Wear one perfume only on vacations or special family days.
Be consistent.
Use it every time you’re in that moment. Your brain will start linking the scent to that feeling.
Then use it when you need a reset.
Feeling overwhelmed? Smell your “calm” scent.
Missing someone? Open a bottle that reminds you of them.
Need motivation? Use the scent you associate with focus.
You’re not just smelling something.
You’re training your brain to remember peace.
To remember joy.
To remember love.
And sometimes, in the middle of chaos, that small anchor is everything.
