New research shows that wearing just 1-3 drops of rose essential oil daily for one month increased gray matter volume in key areas of the brain including the whole brain and the posterior cingulate cortex (used for memory, self-reflection, determining emotional importance). 🌹🧠
No changes were seen in the amygdala or orbitofrontal cortex (taste and odor, reward and punishment, motivation), but this is the first study to demonstrate that continuous scent inhalation can reshape brain structure.
This study was done exclusively in women, so it is unclear if benefits are seen in men.
The brain is always responding to our environment… even to what you smell.
