Easy learning in sleep is a dream for many people, and a new study published in Scientific Reports by a team of researchers at the University of Freiburg in Germany has shown for the first time that odor sits in support of learning success in learning and sleep,media reported.
The researchers conducted several experiments with 54 students in two sixth-grade schools in southern Germany. Participants in the first group were asked to place rose-scented incense on the table at home and on the bedside table while learning English vocabulary at night.
In another group, the researchers placed incense on a table next to them while the school tested English vocabulary. The result is eventually compared to test results in one or more stages that do not use incense.
The results showed that if aromatherapy was used during both study and sleep, the student’s learning success rate would be significantly increased by about 30%. The researchers also found that the use of incense in vocabulary tests boosted memory.
Previous studies have suggested that this scent only needs to be present during the particularly sensitive sleep phase. But because this sleep phase requires effective measurements of brain activity in the sleep lab using an electroencephalogram, the finding is not suitable for everyday use.
In addition to the initial ground-breaking findings, the researchers say, the new study has a particular finding that the scent also works when it exists all night, making it suitable for everyday use.
