 note = {Acute stress affects the sleep architecture and the pattern of autonomic nervous activities during sleep. The odor of lavender is semantically evaluated as a sedative, and the inhalation of lavender increases parasympathetic nervous activity and decreases the heart rate in waking humans. We examined whether the odor of lavender, with sub-threshold concentration, ameliorates the effects of stress on the sleep architecture and cardiac functions during sleep in college students exposed to fi rst-night stress, which was brought about by sleeping in a laboratory with experimental settings. Polysomnography and the parameters of a fast Fourie’s transform (FFT) analysis of heart beat intervals were compared between a lavender-inhaling group (EXP) and a control group not inhaling lavender (CONT). Heart beat intervals increased both in CONT and EXP during sleep, but those in EXP was greater especially in the latter half of sleep. FFT analysis showed that the high frequency power (HF), an indicator for cardiac parasympathetic activity, failed to increase and the ratio of low frequency power (LF) to HF (LF/HF) did not decrease during sleep in CONT. In contrast, HF increased and LF/HF decreased in EXP. Therefore, inhaling lavender maintained the normal nocturnal pattern of cardiac autonomic activities even in the sleep of participants exposed to stress. The odor of lavender caused no difference in sleep architecture between CONT and EXP. We concluded that the odor of lavender ameliorates the infl uence of stress on the brain mechanisms subserving the circadian rhythm of autonomic nervous activities and maintains their activity pattern during sleep.},
