Relaxation can be found as a significant factor that promotes a higher level of sleeping quality. To explore the correlation between relaxation and aroma, this experiment was conducted in University of British Columbia to measure people’s relaxation levels after providing three different scent conditions. The three scents includes lavender, yuzu, and neutral scent, which was water. We examined how each scent has an influence on promoting relaxation to a certain degree by using an online questionnaire survey. Our participants smelled each type of scent first and then gave an answer about how relaxed they felt afterwards. The results showed that there is a significant difference in the levels of relaxation between the aroma scents condition and the control condition, which demonstrates that regardless of lavender or yuzu, people felt more relaxed after smelling pleasant aroma scents compared to a neutral scent. Our research can be applied to the project of building UBC napping area by implementing a pleasant aroma scent, in sequence to providing a comfortable sleeping environment for students.
