Abstract

Background: Sleep hygiene education (SHE) and lavender essential oil (LEO) inhalation are two effective strategies aimed at enhancing sleep quality and mood states. This study investigated the effects of a single SHE session combined with nightly LEO inhalation for 7 days of late-evening resistance training sessions on sleep quality and mood states in trained athletes. Methods: Forty-two athletes were randomly assigned to four groups: a control group (CG), a SHE group (SHEG), a LEO group (LEOG), and a SHE + LEO group (CSLG). CG and LEOG maintained their sleep habits during the intervention, while SHEG and CSLG followed SHE recommendations. Additionally, LEOG and CSLG inhaled LEO nightly before sleep. Sleep patterns were recorded via actigraphy. The Brunel Mood Scale and the Hooper questionnaires were completed before and after the intervention. Results: Sleep latency was lower in SHEG (p=0.001) and CSLG (p=0.012) compared to the CG. The subjective sleep score improved in SHEG, LEOG, and CSLG (p < 0.001), with
