Effectiveness of 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.

The design of the yoga lessons was based on a past study and a professional yoga instruction book. Yoga lessons were led by certified yoga tutors.
