The Night Shift Is Tough on the Heart

In this study, researchers analyzed data concerning more than 320,000 people and found that individuals who routinely work nights are 13% more likely to develop coronary heart disease than daytime workers. The cause of the increased risk is unknown, but the research team speculates that disruption of the normal sleep-wake cycle, increased stress, and unhealthy lifestyles associated with shift work may be factors for the increased risk.
