Research published in the British Medical Journal shows that shift workers have a 23% increased risk of heart attack and a 5% increased risk of stroke.

 

The study, conducted by researchers in Canada and Norway, analysed 34 studies previously published in the BMJ, involving more than two million people. It concluded that shift work is associated with vascular events, which may have implications for public policy and occupational medicine.
