A 2023 study out of the University of California, Irvine exposed older adults to specific scents during sleep, over several months (keep reading to find out which ones).
The result?
Participants showed a 226% greater improvement in memory tests compared to a control group. Even more interesting… this wasn’t just about memory recall.
The repeated exposure to different scents appeared to stimulate and strengthen the neural pathways involved in cognition, supporting the brain’s ability to adapt and change—what scientists call brain plasticity.
Not medication. Not invasive treatments. Just the consistent, gentle stimulation of a pathway God already designed.
Does this make you think differently about the tools we’ve been given? If scent can trigger memories…what might it do when used consistently, and with intention?
What are you diffusing tonight?
If this got your attention, the next question is…
What scents would you even use?
In the study, participants were exposed to different natural scents (rose, orange, eucalyptus, lemon, peppermint, rosemary, and lavender) over several months. Notice the variety?
Different scents stimulate different pathways in the brain, and rotating them appears to help strengthen those neural connections more effectively—supporting brain plasticity over time.
So instead of trying to find one oil that does everything… it actually makes more sense to use a few intentionally.
Here are a couple of simple options:
Young Living’s Harmony Essential Oil Blend
Contains: lavender, orange, lemon, rosemary, and rose (along with other supporting oils)
→ This is one of the closest “all-in-one” blends and a beautiful place to start
Young Living’s Brain Power Essential Oil Blend
Contains: rosemary, peppermint, and citrus oils
→ More focused on clarity, memory, and mental sharpness
Young Living’s Raven Essential Oil Blend
Contains: eucalyptus and peppermint
→ Cooling, refreshing, and supportive for clear breathing
And then… you can keep it simple with a few single oils:
Rose → deeply calming, emotionally grounding
Orange → uplifting and mood-brightening
Lemon → fresh, energizing, and clarifying
Lavender → calming and supportive for sleep
Eucalyptus → opens the airways and refreshes
Peppermint → stimulating and mentally awakening
Rosemary → strongly associated with memory and recall
And here’s the key. You don’t need to use them all at once. Rotate them.
Night 1: something calming (like lavender or Harmony)
Night 2: something bright (like lemon or orange)
Night 3: something stimulating (like rosemary or peppermint)
Night 4: something refreshing (like eucalyptus or Raven)
Then repeat.
Simple, consistent variation—working with the pathways God already designed.
No extremes. No complicated routines. Just small, intentional inputs over time.
