摘要

Flower tea has gained attention for its potential health benefits, yet empirical evidence regarding its comprehensive effects on human physiology and psychology remains limited. This study aimed to investigate how both visual stimulation by flowers and the act of drinking flower tea influence physiological and psychological relaxation. Twenty-nine university students (mean age: 21.0 ± 2.0 years) participated in a within-subject experimental design consisting of four stages: (1) resting with their eyes closed for 1 min (rest (before) period), (2) viewing tea with flowers, tea without flowers, or water (control) for 1 min after opening their eyes (viewing period), (3) drinking it for 3 min (drinking period), (4) closing their eyes again and resting for 1 min (rest (after) period), (5) responding to the questionnaire, and (6) taking a break for 5 min. After completing this sequence, the same process was repeated using a different stimulus. Heart rate variability and heart rate were measured as physiological indicators, while the Profile of Mood States and semantic differential scales were used as psychological indicators. Results showed that viewing tea with flowers significantly enhanced parasympathetic nervous system activity compared to other stimuli. Further, tea with and without flowers enhanced vigor alleviated total mood disturbances, and induced positive feelings throughout the entire process. These findings demonstrate that the combined visual and olfactory–gustatory experience of flower tea promotes physiological and psychological relaxation, suggesting its potential as an effective everyday method for stress relief and emotional well-being.
