Night shifts increase health risks

The British Medical Journal has reported the findings of a study that has identified a correlation between people who work night shifts and irregular hours, and the prevalence of heart disease.

Shift work can interrupt the body’s normal rhythms, and interference with the body clock is linked with risks of diabetes, high cholesterol and raised blood pressure. Those health issues are associated with cardiovascular disease, heart attacks and strokes. Professor Hackam, a clinical pharmacologist who headed up the research team, concluded that night shift workers are 41% more likely to have heart disease. In the UK it is estimated than around one in five workers have shifts that include night duty.
