Lavender Oil (Aromatherapy) for Sleep Quality

Research suggests that lavender oil aromatherapy may offer modest benefits for sleep quality across several clinical populations, with three randomized controlled trials reporting improvements in sleep disturbance scores among patients undergoing chemotherapy, individuals with multiple sclerosis, and women in late pregnancy. Studies indicate that findings lean in a generally supportive direction, with two of the three trials reporting statistically significant improvements in sleep quality using validated measures such as the Pittsburgh Sleep Quality Index, while the chemotherapy trial produced more mixed results, showing changes in sleep scores but limited effects on state anxiety. Limitations across these studies include small sample sizes, specialized patient populations that may not reflect the general public, and the inherent difficulty of blinding participants in aromatherapy research, all of which make it difficult to generalize findings broadly. Further large-scale trials across diverse populations would be needed before stronger conclusions can be drawn.
