HealthDay News — According to a report from the RAND corporation — a nonprofit research organization — reduced productivity and an increased mortality risk associated with lack of sleep among US workers cost the nation’s economy as much as $411 billion a year, which is more than 2% of the country’s gross domestic product (GDP).
The United States suffers the largest economic toll and most working days lost due to sleep deprivation, compared with 4 other developed countries examined by the researchers.
Japan is second, losing up to $138 billion annually, which is 2.92% of its GDP. Japanese workers lose an average of 604,000 working days to a lack of sleep, the researchers found.
Germany loses up to $60 billion a year, or 1.56% of its GDP. An average of 209,000 working days are lost to sleep deprivation in Germany, according to the report.
The United Kingdom loses up to $50 billion annually, or 1.86% of its GDP to a lack of sleep. Approximately 207,000 working days are lost as a result of poor sleep in the United Kingdom.
Canada was last on the list, but still loses about $21.4 billion to sleep deprivation. That’s 1.35% of Canada’s GDP. About 78,000 working days are lost.
“Our study shows that the effects from a lack of sleep are massive. Sleep deprivation not only influences an individual’s health and well-being but has a significant impact on a nation’s economy, with lower productivity levels and a higher mortality risk among workers,” lead author Marco Hafner said in a RAND news release.
“Improving individual sleep habits and duration has huge implications, with our research showing that simple changes can make a big difference. For example, if those who sleep under 6 hours a night increase their sleep to between 6 and 7 hours a night, this could add $226.4 billion to the US economy.”
