Hormonal

Short habitual sleep duration (≤6 hours) and specific insomnia symptoms (sleep continuity disturbance, early-morning awakening, and combined symptoms) significantly increase the incidence of hypertension in adults.

Prioritize consistent sleep duration of 7-8 hours and address sleep maintenance issues (waking up during the night) or early morning awakenings, as these specific patterns are linked to higher blood pressure risk. While difficulty falling asleep (DFA) was not significantly linked in this analysis, chronic sleep fragmentation (SCD) and early awakening (EMA) are. If you have trouble staying asleep or waking up too early, discuss this with your doctor as part of hypertension prevention.

GoodSupportsHIGH confidence
Short sleep duration, sleep continuity disturbance (SCD), early-morning awakening (EMA) and combined symptoms of insomnia increased the risk of hypertension incidence (the relative risks (95% confidence intervals) were 1.21 (1.05–1.40) for short sleep duration, 1.20 (1.06–1.36) for SCD, 1.14 (1.07–1.20) for EMA and 1.05 (1.01–1.08) for combined insomnia symptoms).
