A recent study has found that using a scent diffuser with rosemary essential oil at night can improve memory in older adults.
150 adults aged 65 and above were randomly split into three groups: one used rosemary essential oil, another used lavender essential oil, and the third used a placebo.
After four weeks, the group using the rosemary essential oil showed significant improvement in memory compared to the other two groups.
Rosemary essential oil is believed to have cognitive benefits due to its ability to increase blood flow to the brain and its antioxidant properties.
The study suggests that using a scent diffuser with rosemary essential oil at night could be a simple and natural way to improve cognitive function in older adults.
However, more research is needed to confirm these findings and determine the optimal dosage and duration of use.
