Did you know our sense of smell is closely connected to memory?
I love discovering the science behind something as simple as our sense of smell, and this study really caught my attention.
Researchers looked at whether using different aromas at bedtime could make a difference to memory in adults aged 60–85.
For six months, one group experienced seven different aromas, using one each night for two hours. The other group had the same routine but without the scented oils.
The researchers reported a significant improvement in memory test performance in the group exposed to the aromas, alongside changes in a brain pathway linked to memory and decision-making. Essential oils used were: rose, orange, eucalyptus, lemon, peppermint, rosemary and lavender.
As a mum, I love finding simple ways to make everyday routines feel special. A familiar bedtime scent, a calming story and a little time to wind down can become lovely moments of connection at the end of a busy day.
I’m always curious about the science behind the little things we often take for granted.
Have you ever noticed how a particular smell can take you straight back to a memory? I’d love to hear yours.
