Effects of Essential Oil Aromatherapy on Sleep, Depression, and Well‐Being Among Older Adults: Implications for Community Health and Social Care

Background Population aging presents major healthcare challenges, with sleep disorders and late‐life depression undermining older adults’ well‐being. Aromatherapy, a nonpharmacological approach, shows potential in alleviating these conditions through olfactory stimulation of the limbic system, reducing stress and enhancing emotional balance. Objectives This study evaluated the effects of essential oil aromatherapy on sleep quality, depression, and subjective well‐being among older adults in long‐term care facilities. Methods A quasiexperimental study was conducted in six facilities from January to April 2024. Ninety residents were assigned to weekly or monthly aromatherapy groups or a control group. Interventions lasted three months and used 30 essential oils. Outcomes were measured with the Pittsburgh Sleep Quality Index, World Health Organization–Five Well‐Being Index, and Geriatric Depression Scale. Results Weekly aromatherapy significantly improved sleep latency, reduced sleep disturbance, and enhanced well‐being in feelings of refreshment, interest, and happiness. Both weekly and monthly sessions reduced depressive symptoms. Regression analysis showed stronger improvements among males, while advancing age was negatively associated with outcomes. Conclusions Regular aromatherapy sessions can improve sleep, reduce depression, and enhance well‐being in older adults. Beyond clinical effects, the findings highlight social care implications: incorporating low‐cost, accessible interventions into long‐term care routines may foster social interaction, emotional support, and residents’ sense of belonging, contributing to holistic and community‐oriented elder care.
