Aim: The aim of this research was to explore the association between subjectively reported sleep duration and blood pressure (BP).

Methods: The measured BP values were compared with 7-day records of sleep duration in the population of adults aged 19-72 years (n = 126). Additional information about sleep was obtained through the questionnaire method.

Results: Sleep < 6.9 h was associated with a significantly higher diastolic BP (median 90.2 mm Hg) compared to subjects sleeping 7-7.9 h (median 85.0 mm Hg) and > 8 h (mean 83.8 mm Hg), P = 0.006. The diastolic blood pressure negatively correlated to a significant extent with sleep duration even when taking into consideration age and BMI (r = -0.22, P = 0.016).

Conclusion: Extremely short sleep is a potential risk factor contributing to high blood pressure and hypertension. Sufficient sleep may play an important role in the prevention of high BP and cardiovascular disease.

Keywords: sleep duration, sleep restriction, blood pressure, hypertension
