Study Reveals Rose Scent Improves Learning During Sleep
Fun learning during sleep is the dream of many people. The supportive impact of smells on learning success when offered both throughout learning and sleep was first confirmed in an extensive sleep laboratory research.
Researchers at the University of Freiburg— the Faculty of Biology at the Freiburg University and Medical Center, the Freiburg Institute for Frontier Areas of Psychology and Mental Health have now proven that this effect could be achieved very simply outside the lab.
For the research, pupils in two school lessons realized English vocabulary—with and without scent sticks through the learning interval and also at night.
The scholars remembered the vocabulary significantly better with a scent. The research was printed in the Nature Group’s Open Access journal Scientific Stories on 27 January 2020.
For the study, the lead author and teacher Franziska Neumann conducted a number of tests with 54 participants from two 6th grade classes of a southern German school.
The young members from the test group had been asked to place rose-scented incense sticks on their desks at home while studying English vocabulary and on the bedside table beside the mattress at night.
In another experiment, they placed the incense sticks on the table after them during a vocabulary test at college throughout an English test. The outcomes had been in contrast with test outcomes in which no incense sticks have been used during a number of phases.
The results further suggest that the additional use of the incense sticks during the vocabulary test improves memory.
