Effect of Shift Work on Hypertension: Cross‑sectional Study
Summary
This cross-sectional study evaluated 1,953 male petrochemical workers in South Korea to examine the link between shift work and hypertension. Compared to day workers, shift workers had significantly higher odds of high blood pressure (adjusted OR 1.51). The risk was even greater for those with 20 or more years of continuous shift work, underscoring the cumulative cardiovascular burden of long-term exposure.
Why It Matters For Night Shift Workers and Night Owls
For night-shift workers, this study makes clear that irregular schedules can raise blood pressure in measurable ways, not just leave you feeling tired. Longer or more continuous stretches of night duty appear especially risky, pointing to a cumulative effect on cardiovascular health. The findings highlight the importance of regular blood pressure monitoring for shift workers and support workplace policies that limit extended runs of night shifts. For individuals, it emphasizes that schedule design and recovery time aren’t just about comfort—they directly impact heart health.
