[Purpose] Inhalational aromatherapy using lavender essential oil or essence is known to alleviate pain and anxiety during rehabilitation. However, the effects remain unclear in individuals who are unaware of their pain and anxiety. In this study, we investigated the effects of lavender aromatherapy during sleep in females who did not experience pain or anxiety. [Participants and Methods] The study included 24 healthy females who were randomly allocated to control and aromatherapy groups. The control group used skin patches without aroma, and the aromatherapy group used lavender aroma-infused skin patches for seven consecutive nights. Psychological and physiological indices were measured before, during, and after the intervention. [Results] The lavender aroma-infused skin patches ameliorated a negative mood associated with fatigue and anxiety. However, neither group showed a change in pulse rate and salivary cortisol concentration upon waking. Furthermore, no significant intergroup difference was observed in sleep quality. [Conclusion] Lavender aromatherapy during sleep improved a negative mood associated with fatigue and anxiety in females who did not experience pain and anxiety; however, physiological indices remained unaffected.
[目的] 使用薰衣草精油或精华进行吸入式芳香疗法，已知可缓解康复期间的疼痛和焦虑。然而，对于未意识到自身疼痛和焦虑的个体，其效果仍不明确。在本研究中，我们调查了薰衣草芳香疗法对未经历疼痛或焦虑的女性睡眠的影响。[参与者与方法] 该研究纳入了24名健康女性，她们被随机分配到对照组和芳香疗法组。对照组使用无香气的皮肤贴片，芳香疗法组连续七个晚上使用注入薰衣草香气的皮肤贴片。在干预前、干预期间和干预后测量心理和生理指标。[结果] 注入薰衣草香气的皮肤贴片改善了与疲劳和焦虑相关的负面情绪。然而，两组在醒来时脉搏率和唾液皮质醇浓度均未出现变化。此外，睡眠质量方面未观察到显著的组间差异。[结论] 睡眠期间的薰衣草芳香疗法改善了未经历疼痛和焦虑的女性与疲劳和焦虑相关的负面情绪；然而，生理指标未受影响。
