THE PHYSIOLOGICAL AND EMOTIONAL RESTORATIVE EFFECTS OF ORIENTAL HYBRIDS ON STRESSED YOUTH: AN INTERACTIVE SMELL AND SIGHT STUDY

Aromatherapy is gaining popularity as a method to regulate mood and relieve stress.This study aims to investigate how the smell of flowers and the interaction between sight and smell influence physiological indicators like blood pressure, pulse, heart rate variability, Galvanic skin signals, brain waves and Total Mood Disturbance (TMD) in stressed young individuals, and further explored the differences in the effects between the two groups, as well as on the main constituents of floral scent.Oriental Lily (Oriental hybrids) was used as the material for the olfactory, visual-olfactory interaction and no-olfactorycontrol groups of perceptual experiments.Aroma composition and emission rate of Oriental lilies were analyzed by headspace solid-phase microextraction (GC-MS SPME) technique.The following results were obtained: 1) Both the olfactory and visual-olfactory interaction groups experienced reductions in blood pressure, pulse, electrodermal activity, beta-wave power spectral density, emotional disturbance scores and showed improved heart rate variability and a significant increase in brain alpha wave activity.2) The VOIG group was more effective than the OG group in restoring physical and emotional well-being.3) Monoterpenes are identified as the primary aroma components of Oriental lilies, constituting 66.18% of the relative content of volatile components.
