Aromatherapy is a simple, non-invasive complementary therapy that may help reduce fatigue and improve sleep. Agarwood (Aquilaria spp.) has calming and relaxing properties, but there is little clinical research on its effectiveness for hospital staff.\n\nThis randomized, double-blind, controlled trial will evaluate whether agarwood aromatherapy inhalation can improve fatigue and sleep quality among hospital employees in Taiwan. About 78 participants will be recruited and randomly assigned to one of two groups:\n\n1. Experimental group: Agarwood sachet containing agarwood wood chips and essential oil.\n2. Control group: Placebo sachet containing almond oil.\n\nParticipants will place the sachet about 60 cm from the nose during sleep for 7 nights. Data will be collected using questionnaires on workplace fatigue and sleep quality (Pittsburgh Sleep Quality Index, PSQI). The main questions this study aims to answer are: 1. Does agarwood aromatherapy reduce workplace fatigue in hospital staff? 2. Does agarwood aromatherapy improve sleep quality compared with placebo?\n\nFindings are expected to provide scientific evidence for using agarwood inhalation as a safe and convenient strategy to improve staff well-being and support a healthier hospital environment.",[53,54,55],"Fatigue","Occupational Stress or Workplace Stress","Sleep Quality","NOT_YET_RECRUITING","2025-09-16",{"date":59,"type":60},"2025-09-23","ACTUAL",{"date":62,"type":47},"2025-09",{"date":64,"type":47},"2026-07",{"name":5,"class":6}]
