In today's fast-paced lifestyles when our sleep cycles have gone for a toss, it is difficult to get a sound sleep. However, it isn't impossible at the same time.
If you also happen to be someone who isn't able to wake up fresh due to lack of sleep or disturbed sleep, here is a bit of good news for you. According to a latest study, published in the journal—Nature Group's Open Access journal Scientific Reports, smelling the scent of rose can improve your quality of learning and can also help you in sleeping better.
The study was conducted within pupils of two classes that learned English vocabulary, one of which learned it with the scent sticks while the other one did it without it.
At the end of the study, it was found that students were able to remember the vocabulary better in the presence of the scent.
"We showed that the supportive effect of fragrances works very reliably in everyday life and can be used in a targeted way," the lead researchers, Dr. Jurgen Kornmeier said.
One of the authors of the study Franziska Neumann conducted several experiments with a group of 54 students belonging to two classes of grade six.
The participants were asked to place rose-scented incense sticks on their desks while learning English vocabulary and were also asked to put a stick at the table next to their bed.
In another test, the participants were asked to add incense sticks on the table next to them during the vocabulary test. The results were then compared with the results where no incense sticks were used in one or more phases.
"The students showed a significant increase in learning success by about 30% if the incense sticks were used during both the learning and sleeping phases," said Neumann.
"One particular finding beyond the seminal initial study was that the fragrance also works when it is present all night. This makes the findings suitable for everyday use," says Kornmeier.
"Our study shows that we can make learning during sleep easier. And who would have thought that our nose could help considerably in this," adds Kornmeier.
