In November 2012, I wrote about a study that found insomnia costs American businesses up to $31 billion every year - mainly through mistakes and injuries.
Now a new study suggests that insomniacs with a depressive or anxiety disorder have higher rates of absenteeism and are more likely to suffer from poor work performance.
The result? A tangible individual financial cost and the potential for further health complications.
The study involved almost 1,500 individuals. 707 had a current depressive or anxiety disorder, and of these 385 had insomnia.
Researchers found that these 385 insomniacs were 1.63 times more likely to have impaired work performance and were more than twice as likely to have been absent from work due to health issues for more than 2 weeks in the past 6 months, compared to healthy sleepers.
What makes this study particularly interesting is the fact that the link between sleep disturbance and work performance was found almost exclusively in those with depressive or anxiety disorders.
Insomnia sufferers without current psychopathology were no more likely to have higher rates of absenteeism or reduced workplace performance than healthy sleepers.
