Working long hours could increase the likelihood of developing mental health issues.
According to a study by the Finnish Institute of Occupational Health and University College London, there is a significant link between working overtime and experiencing depression, including in later life.
The link was unaffected by socio-demographic factors, lifestyle, and other work-related issues.
It found that those working 11 hours or more a day had double the chance of entering a major depressive episode than those who worked just seven to eight hours.
"Although occasionally working overtime may have benefits for the individual and society, it is important to recognise that working excessive hours is also associated with an increased risk of major depression," explained lead study author Marianna Virtanen.
However, depression may not be as easy to treat in older people as earlier this month researchers from Erasmus University Medical Centre found that antidepressants can increase the risk of falls in dementia patients.
