People who work longer are more likely to seek solace in alcohol, new research finds.
It has long been accepted that long days can lead to exhaustion, mental health problems and even relationship breakdown, but the new study has shown for the first time that employees who put in extra are at higher risk of turning to drink, compared to those who leave on time.
Employees who work more than 55 hours a week are 13 per cent more likely to consume "risky" levels of alcohol.
Scientists say the link "cannot be ignored". The study of 330,000 people provides the first systematic analysis of the relationship between working hours and alcohol use.
Scientists already know there is a significant increase in physiological ill-effects associated with increasing working hours from 8 to 12 hours a day.
However the authors of the new study, carried out across 14 countries and published in the BMJ journal, say that effectively regulating working hours should be considered as a crucial public health intervention.
