Fatigue poses risks to occupational health and safety, affecting individuals' work efficiency, physical health, and social security, as well as human wellbeing and quality of life. Olfactory interventions, due to their low interference, are considered promising strategies for mitigating fatigue and reducing occupational health hazards.
The objective of this review is to bridge the current gaps in the literature by conducting a scoping review of olfactory interventions on human alertness. It aims to explore their application in various occupational settings and to provide comprehensive and practical guidance for the practical application of olfactory interventions in mitigating fatigue and reducing occupational risks.
The literature research was conducted in English using electronic databases such as Web of Science. Keywords related to scent and fatigue and the review followed PRISMA Extension for Scoping Reviews and PICO framework.
28 studies were included in this work. Participant characteristics, fatigue measurement methods, and scent intervention methods, such as types of scents, intervention strategies, and scent presentation systems, are thoroughly investigated and discussed. Additionally, the study places a specific emphasis on the applications and research within the field of scent interventions for fatigue driving. Olfactory interventions have been applied to populations in various occupational fields, demonstrating beneficial effects on both physiological and psychological fatigue.
Olfactory intervention is effective and promising for enhancing alertness and improving the occupational environment. To provide detailed and practical guidance for the actual application of olfactory intervention in fatigue relief and reducing occupational health and safety hazards, further research into the potential mechanisms, applications, and efficacy assessment systems of fatigue-related olfactory interventions is necessary.
疲劳对职业健康和安全构成风险，影响个人的工作效率、身体健康和社会保障，以及人类福祉和生活质量。嗅觉干预因其干扰小而被认为是缓解疲劳和减少职业健康危害的有前途的策略。
本综述旨在通过对人类警觉性的嗅觉干预进行范围界定审查，弥补当前文献中的空白。它旨在探索嗅觉干预在各种职业环境中的应用，并为嗅觉干预在缓解疲劳和减少职业风险中的实际应用提供全面实用的指导。
文献检索使用了 Web of Science 等电子数据库以英语进行。关键词与气味和疲劳有关，综述遵循 PRISMA 扩展范围界定综述和 PICO 框架。
共纳入 28 项研究。研究深入探讨和讨论了参与者特征、疲劳测量方法以及气味干预方法，如气味类型、干预策略和气味呈现系统。此外，该研究特别关注嗅觉干预在疲劳驾驶领域的应用和研究。嗅觉干预已应用于各种职业领域的人群，对生理和心理疲劳均显示出有益的效果。
嗅觉干预对提高警觉性和改善职业环境是有效且有前途的。为了为嗅觉干预在缓解疲劳和减少职业健康和安全危害方面的实际应用提供详细实用的指导，有必要进一步研究与疲劳相关的嗅觉干预的潜在机制、应用和疗效评估系统。
