Essential oils have potential to mitigate stress symptoms and treat symptoms related to mental health. Few studies have investigated the effects of wood-derived aromatics on endocrinological and psychological responses in an actual space. In this study, we evaluated the effects of essential oil derived from Japanese cedar (Cryptomeria japonica) wood on the recovery state of female participants after they performed monotonous work. We determined the levels of salivary stress markers to describe the endocrinological responses. And we also used questionnaires to assess the perception of the odor of experimental rooms and psychological states. We found that olfactory stimulation with the volatile compounds of essential oil derived from Japanese cedar wood modulates mood states, and may transiently decrease sympathetic nervous activity. We suggest that olfactory stimulation with the volatile compounds of essential oil derived from Japanese cedar wood could be useful for maintaining mental health among women.

吸入日本柳杉（Cryptomeria japonica）木味会使女性参与者单调工作后心理放松。

精油具有缓解压力症状和治疗与心理健康有关的症状的潜力。很少有研究调查木材衍生的芳烃在实际空间中对内分泌和心理反应的影响。在这项研究中，我们评估了日本雪松（Cryptomeria japonica）木材中精油对女性参与者单调工作后恢复状态的影响。我们确定了唾液应激标志物的水平来描述内分泌反应。我们还使用问卷调查来评估对实验室气味和心理状态的感知。我们发现嗅觉刺激与源自日本雪松木的挥发油的挥发性化合物可调节情绪状态，并可能暂时降低交感神经活动。
