ABSTRACT
BACKGROUND: This study aimed to investigate the effects of sleep hygiene education on blood pressure and sleep quality in patients diagnosed with essential hypertension.
METHODS: A randomized controlled trial was conducted with 138 patients with essential hypertension at a family practice center in southern Turkey. Participants completed Pittsburgh Sleep Quality Index (PSQI) and their blood pressure was measured during the initial visit. Patients randomly assigned to the intervention group received sleep hygiene education during the same session. To support adherence, these participants were asked to keep a sleep diary for 8 weeks. At the end of this period, both groups were reassessed using the PSQI and blood pressure measurements. Data were analyzed using SPSS version 22.
RESULTS: In our study, completed with 129 participants, sociodemographic characteristics were similar across groups. In the intervention group, the mean reduction in PSQI score was 3.4 points (95% CI: 2.8-4.0; P < 0.001). Systolic blood pressure decreased by 9.7 mmHg (95% CI: 7-12.5; P < 0.001), and diastolic blood pressure decreased by 6.3 mmHg (95% CI: 4.2-8.4; P < 0.001). No significant changes were observed in the control group.
CONCLUSIONS: Sleep hygiene education delivered in a primary care setting significantly improved sleep quality and reduced blood pressure levels in patients with essential hypertension. This approach may also help prevent complications related to hypertension. Clinical trial registration: ClinicalTrials.gov (Identifier: NCT07257237; registered on 20 November 2025).
