Lavender for Sleep: Aromatherapy and Supplements
Lavender works through two channels — scent and capsule — and both have some research behind them. How lavender oil affects sleep, and which delivery method the evidence favors.
Key takeaways
- Lavender aroma is linked to reduced anxiety and improved sleep quality in multiple small trials, including hospital settings.
- Oral lavender oil capsules (Silexan-type, 80–160 mg) show anxiety reduction with secondary sleep benefits in larger trials.
- Diffusing lavender oil 30 minutes before bed is low-risk; apply diluted oil only to skin, never ingest raw essential oil.
- Scent effects fade with constant exposure — use it in the wind-down hour rather than all night.
- Lavender is a relaxation aid, not an insomnia treatment; pair it with stronger behavioral strategies for real sleep problems.
