Lavender scent improves sleep quality and physical balance in elderly individuals
In a randomized controlled trial of 90 elderly participants, those who slept with lavender pouches for one month showed significant improvements in sleep quality (PSQI total score decreased from 6.11±2.86 to 4.33±2.07, p<0.05) and physical balance (BBS score increased from 38.31±11.84 to 41.48±10.82, p<0.05). Sleep latency also decreased significantly.

The Claim
Lavender scent improves sleep quality and physical balance in elderly individuals
This conclusion is most relevant to: Elderly individuals (mean age not specified, but sample of 90 elderly, 45 per group).
What the Research Shows
The conclusion draws on 1 linked study. Highlights from the cited literature:
- ▸The effect of lavender scent recommended to the elderly on sleep quality and physical balance: A randomized controlled trial. (Geriatric nursing (New York, N.Y.), 2026) —
How It Works
The proposed biological pathway:
- ▸Lavender scent is inhaled during sleep
- ▸Lavender aroma may activate olfactory pathways
- ▸This may induce relaxation and reduce anxiety
- ▸Result: Improved sleep quality and balance outcomes
Who Might Benefit
Evidence fit by population:
- ▸Elderly individuals (mean age not specified, but sample of 90 elderly, 45 per group)
Recommended Dose
N/A
Limitations & Caveats
Important context when interpreting this evidence:
- ▸Abstract does not report blinding details or allocation concealment
- ▸No follow-up after the intervention period to assess long-term effects
- ▸No objective sleep measures (e.g., polysomnography) used
- ▸Potential placebo effect not fully addressed
Frequently Asked Questions
How long did the lavender intervention last?▼
The intervention lasted for one month, with participants sleeping with lavender pouches in their pillows.
What was the sample size and design?▼
The study was a randomized controlled trial with 90 elderly participants (45 in the lavender group, 45 in the control group).
What were the key outcomes measured?▼
Sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI), and physical balance was measured using the Berg Balance Scale (BBS).
Did the lavender group show significant improvements?▼
Yes, the lavender group showed significant improvements in sleep quality (PSQI total score decreased) and balance (BBS score increased) compared to pre-test, with p<0.05.
