A new study has found that certain scents can help improve memory and potentially deter dementia while you sleep.
The study tested three scents: rose, lavender, and frankincense.
Participants were exposed to the scents while they slept and then tested on their memory recall.
The results showed that those exposed to the scents had improved memory recall compared to those who were not exposed.
The study suggests that these scents could potentially be used as a non-invasive way to improve memory and prevent dementia.
Further research is needed to fully understand the potential benefits of these scents.
