Effects of inhaling <i>Cunninghamia lanceolata</i> essential oil on the physiological and psychological relaxation of university students.

ABSTRACT: University students face multiple stressors, which can impair their physical and mental health without timely intervention. Despite the close link between nature and wellbeing, as well as the growing interest in using natural substances for health management, the effectiveness of Cunninghamia lanceolata essential oil (C. lanceolata EO) in alleviating emotional disorders among university students remains underexplored. This study investigated the physiological and psychological effects of inhaling C. lanceolata EO among 40 healthy university students (mean age: 21.75 ± 1.82 years). Subjects inhaled room air (control) and C. lanceolata EO for 5 min each. Electroencephalograms (EEG), heart rate variability (HRV), blood pressure (BP), and the Profile of Mood States
