Inhalation of lavender aroma may improve sleep quality by potentially elevating levels of which hormone?

Answer

Melatonin

Lavender's traditional role in promoting rest is supported by current studies suggesting that inhaling its scent may directly influence the body's internal clock regulation mechanisms, specifically by potentially increasing the production or efficacy of melatonin. Melatonin is the critical hormone responsible for signaling the body that it is time to sleep and regulating the overall circadian rhythm. This calming effect has been observed across diverse populations, including those without diagnosed sleep issues and even patients in palliative care settings, where sustained inhalation over several weeks led to measurable improvements in sleep quality. This contrasts with the immediate, sensory-triggered calming response from aromatherapy used for anxiety, suggesting sleep support involves deeper physiological modulation.
