Aromatherapy for Sleep Promotion in the ICU: Insights and Future Directions.

Background: The effects of inhaled aromatherapy on sleep quality in critically ill patients in the intensive care unit (ICU) have been widely studied. Specific essential oil combinations have been highlighted for their potential to promote sleep in these patients.
Aim: To offer additional insights and future directions for the application of aromatherapy in improving sleep quality among critically ill patients, considering the current evidence and addressing gaps in research.
Discussion: While certain blends of essential oils, such as lavender, Matricaria recutita, and neroli, have shown promise, other studies have produced mixed results regarding the optimal aromatherapy interventions. Integrating aromatherapy with other non-pharmacological approaches, such as earplugs, eye masks, or music, may offer enhanced sleep benefits. Further research is needed to evaluate aromatherapy's effects on specific populations, such as intubated patients, and to assess feasibility, cost-effectiveness, and potential adverse effects.
Conclusion: Aromatherapy shows promise for improving sleep quality in critically ill patients but should be integrated with other evidence-based, non-pharmacological interventions. Addressing research gaps is crucial for developing comprehensive strategies to enhance sleep quality in ICU settings.
