NCT ID NCT07368374
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at whether inhaling citrus or clove oil for 2 minutes, three times a week for a month, can reduce fatigue, improve sleep, and enhance quality of life in adults aged 65 and older. Researchers will compare the effects of each oil against a placebo in 51 participants. The goal is to find a simple, drug-free way to support well-being in older adults.
