A team of scientists from the Technical University of Dresden (Germany) found that different scents can affect a person’s health. The results of the researchers’ work were published at: area Nature.
The authors planned to evaluate the effect of odors on sleep quality. The team worked on laurine, orange scent and specially produced scents.
The study included 139 people who evaluated the quality of their sleep for two weeks, the authors also collected data on physiological parameters. The experiment was then repeated, but this time the participants slept with a special device that fed the aforementioned scents into their noses. Odor measurements and various cognitive and non-cognitive measurements were also taken before, after, and after the first experiment.
The results showed that some aromas had a positive effect on sleep and overall health, while some aromas, on the contrary, worsened health. At the same time, we are talking about the self-confidence of the participants – the smells did not affect the physiological parameters.
