Detaljeret beskrivelse

The intervention protocol was established as follows: Based on the elderly participant's usual bedtime, the time of going to bed was recorded. The participant was instructed to assume a comfortable sleeping position, use the graduated dropper provided with the essential oil bottle to measure 0.15 ml (approximately 3 drops; theoretically, 0.05 ml per drop) of diluted lavender essential oil, and drip it vertically onto the upper center of a cotton pad. The cotton pad was then pinned to the collar with a safety pin, and the participant was instructed to inhale the scent evenly for 30 minutes. Afterward, the intervention staff or caregiver will remove the cotton pad. The intervention will be conducted 5 days a week for 12 weeks.
