摘要

背　景：護理人員因工作性質導致睡眠品質不佳，影響自身健康與工作效率為現存普遍之問題。目　的：探討薰衣草芳香療法對女性護理人員睡眠品質改善之成效。方　法：本研究於台南某區域醫院進行類實驗研究，隨機分配100位受試者至實驗組與控制組。實驗組接受薰衣草芳香療法8週（n=48），控制組則未給予介入措施常規入睡（n=47），以測量匹茲堡質量指數（Pittsburgh SleepQuality Index）及心率變異度（heart rate variability, HRV）作為成效指標。結　果：經8週介入研究，實驗組介入前與介入後測得睡眠品質指數達統計差異（p=.005），薰衣草芳香療法介入睡眠品質佳；控制組前、中、後測睡眠品質指數則無統計差異（p=.052）；實驗組之生理指標評量，於心跳、血壓、心律變異性（HRV）、高頻功率（HR）、低頻功率（LF）及自律神經系統平衡指標（LF／HF）之客觀數據皆呈顯著差異（p ＜ .001），顯示薰衣草吸嗅可以降血壓與心跳以達到放鬆效果。本研究結果顯示，薰衣草芳香療法可改善護理人員睡眠品質，且能調節心律變異性、交感與副交感神經，以提昇睡眠品質。結論／實務應用：薰衣草芳香療法對改善女性護理人員睡眠品質具成效，且操作安全簡便，建議關切輪班工作護理人員之睡眠品質，並採取措施，改善工作環境，以提昇護理人員之生活品質。

Background: Poor quality of sleep is a common problem among female nurses due to the nature of nursing work. This situation may impact negatively on their physical and mental health and on their overall work performance. Purpose: This study was designed to explore the effect on the sleep quality of female nurses of sniffing essential lavender oil (lavender aromatherapy). Methods: This quasi‐experimental study was conducted at a regional hospital in southern Taiwan. A total of 100 qualified participants were randomly assigned to either the experimental group or the control group. The experimental group received lavender‐based aromatherapy for eight weeks (n=48) and the control group received no intervention (n=47). The main outcome indexes used the Pittsburgh Sleep Quality Index (PSQI) and heart rate variability (HRV). Results: After eight weeks of the Lavender‐Based Aromatherapy intervention, the differences between the PSQI pretest and posttest scores were statistically significant (p=.005) for the experimental group and not statistically significant (p = .052) for the control group. Furthermore, the control group registered significant pretest/posttest differences in terms of blood pressure, hear rate, heart rate variability (HRV), high frequency (HF), low frequency (LF), and LF/HF (p ＜ .001). The lavender‐based aromatherapy intervention effectively improved the sleep quality of experimental‐group participants. The present study demonstrated that lavender inhalation may have a persistent and short‐term effect on HRV with an increase in parasympathetic modulation that results in improved sleep quality in female nurses. Conclusions / Implications for Practice: The present study supports the efficacy of lavender‐based aromatherapy, a safe and convenient intervention, in improving the sleep quality of nurses. Improving the sleep quality of professional nurses is a priority issue due to their variable shift‐work schedules and critical role in ensuring the delivery of effective, high‐quality public healthcare.
