Scientists have found that smelling the scent of roses while learning and during sleep helps increase memory and learning skills.
The study reports a significant increase in learning success by 30% if a person is exposed to the smell of roses during both learning and sleep phases.
For the study, researchers at the University of Freiburg in Germany recruited 54 students from two 6th grade classes who were learning English vocabulary — one group with scent sticks, and another group without the scent sticks. The students remembered the vocabulary much better with a scent, Neuroscience News reported.
"We showed that the supportive effect of fragrances works very reliably in everyday life and can be used in a targeted way," study leader PD Dr. Jürgen Kornmeier said.
