Poor sleep quality affects disease recovery and overall quality of life. Aromatherapy has been shown to improve sleep quality by alleviating anxiety, promoting relaxation, and enhancing blood circulation. Several meta-analyses have reported the effects of aromatherapy on sleep quality, however, the efficacy varies widely, with some studies showing that the effects are negligible or inconsistent. A comprehensive review synthesizing the available evidence on the impact of aromatherapy on sleep quality is still needed. Therefore, this study aims to provide an umbrella review summarizing all available systematic reviews and meta-analyses investigating the effects of aromatherapy on sleep quality.
A thorough literature search will be conducted across six English-language databases and four Chinese-language databases, following the Joanna Briggs Institute (JBI) methodology for umbrella reviews. Two reviewers will independently screen all articles to determine their eligibility based on pre-established inclusion criteria. Additionally, a manual search will be performed by reviewing the reference lists of the included studies. Data extraction will be conducted from all eligible studies, and the quality will be assessed using the Assessment of Multiple Systematic Reviews-2 (AMSTAR 2) tool. The study selection process will be presented using a PRISMA flow diagram. Statistical analyses will be performed using appropriate statistical methods to summarize and describe the findings.
This study aims to provide comprehensive evidence by systematically evaluating the effects of aromatherapy on sleep quality in patients. It seeks to uncover the impact of aromatherapy on sleep quality across different patient populations and explore variations in its effectiveness based on disease type and the form of aromatherapy used. We will conduct a systematic evaluation of all eligible systematic reviews and meta-analyses. Subgroup analysis will also be performed, if applicable, to divide patients into groups according to how aromatherapy attributes (e.g., population type, dosage, route of administration) and disease types affect the effect size.

睡眠质量差会影响疾病康复和整体生活质量。芳香疗法已被证明可通过减轻焦虑、促进放松和增强血液循环来改善睡眠质量。多项荟萃分析报告了芳香疗法对睡眠质量的影响，然而，其疗效差异很大，一些研究表明这些影响微不足道或不一致。仍需要对芳香疗法对睡眠质量影响的现有证据进行综合综述。因此，本研究旨在提供一项伞状综述，总结所有关于芳香疗法对睡眠质量影响的现有系统评价和荟萃分析。
将按照乔安娜·布里格斯研究所（JBI）的伞状综述方法，在六个英文数据库和四个中文数据库中进行全面的文献检索。两名评审员将独立筛选所有文章，根据预先确定的纳入标准确定其是否符合要求。此外，将通过查阅纳入研究的参考文献列表进行手动检索。将从所有符合要求的研究中提取数据，并使用多系统评价评估工具2（AMSTAR 2）评估质量。研究选择过程将使用PRISMA流程图展示。将使用适当的统计方法进行统计分析，以总结和描述研究结果。
本研究旨在通过系统评估芳香疗法对患者睡眠质量的影响来提供全面证据。它试图揭示芳香疗法对不同患者群体睡眠质量的影响，并根据疾病类型和所用芳香疗法的形式探索其有效性的差异。我们将对所有符合要求的系统评价和荟萃分析进行系统评估。如果适用，还将进行亚组分析，根据芳香疗法的属性（如人群类型、剂量、给药途径）和疾病类型如何影响效应大小将患者分组。
