Working shifts increases a person’s risk of developing ischaemic heart disease, with every year in this working pattern causing a 1% rise in the risk, according to a large study published in the journal, Occupational Medicine.
The research is the largest ever study focusing on the risk of ischaemic heart disease in shift workers. Researchers analysed 21 studies which pooled together 320,002 participants with 19,782 cases of ischaemic heart disease.
Shift workers were found to be 13% more likely to develop ischaemic heart disease compared with daytime workers.
