Study Description

Brief Summary

College students, particularly female students, often suffer from severe stress and poor sleep. Aromatherapy yoga has become a popular exercise in recent years and may help reduce stress and improve sleep quality, although empirical evidence is limited. We investigated the effective-ness of aromatherapy yoga intervention in reducing stress and improving sleep quality among female college students. Eighty-nine participants (44 in the experimental group [aromatherapy yoga] and 45 in the control group [yoga]), with an average age of 19.88 ± 1.13 years, were en-rolled in this quasi-experimental study. Interventions were performed in the respective groups once a week for 12 weeks, for 90 minutes each time. The Wilcoxon signed-rank test and Mann-Whitney U test (including effect size) were used to test the differences in stress reduction and sleep quality before and after the intervention.

Arms and Interventions

Arm	Intervention/Treatment
Experimental: Aromatherapy yoga Each intervention session lasted 90 min, between 6 p.m. and 7:30 p.m. The course was held in a yoga classroom once a week, in an area of 30 m × 35 m. Furthermore, the total intervention period lasted for 12 weeks.	Behavioral: Aromatherapy yoga The research assistant diluted the Lavandula angustifolia essential oil with distilled water (1:75) 10 min before the yoga session started. The solution was then atomized by three aroma diffusers, placed in the front, middle, and back of the classroom. The distance from each participant was less than 10 m to ensure that the aroma was absorbed com-pletely. The yoga course for the aromatherapy yoga group was the same as that of the yoga only group. The yoga group only took a yoga course, without aromatherapy.
