Shift Work Raises Heart Attack and Stroke Risk

Shift work (defined as any work schedule outside of approximately 9:00-17:00 hours) has been found in a meta-analysis of 34 observational studies to significantly increase the risk of heart attacks and ishemic stroke. Smoking and socioeconomic factors did not alter the results. The increase in risk ranged from 5% for stroke to almost 25% for heart attacks and other coronary events.

PositiveTip: Shift workers should be vigilant about modifying their known risk factors for vascular disease.
