1/3 of workers in the U.S. aren’t getting enough sleep, reducing their ability to do their jobs properly that translates to a shocking $63.2 billion in lost productivity.


2American Academy of Sleep Medicine.

Average worker in the USA loses 11.3 working days of productivity a year because of not getting enough sleep. “Respective calculations for Europe are not currently available, but a similar economic burden is reasonably assumed.” (ESRS, European Sleep Research Society). 23% of US employees experienced some form of insomnia at least three times a week during the previous month.

Not surprisingly, these sleep problems carried over into the workplace. Insomniacs were no more likely than their well-rested peers to miss work, but they were so consistently tired on the job that they cost their employers the equivalent of 7.8 days of work in lost productivity each year — an amount equal to an average of about $2,280 in salary per person.

In Belgium, stress and tiredness is responsible of 37% of sick leaves which costs around 800 euros per employee per day. In France, 1/3 person is lacking sleep and 1/5 suffers insomnia. In UK, 86% of parents admitting to suffer from fatigue.

“When we are tired, we find it much harder to think innovatively and to make creative leaps.”

    Tiredness As A Risk Factor

    Since than more than 20% of people are “morning larks” (doing their best work in the morning) and more than 20% are “night owls” (doing their best work in the evening), a little bit less than half of your employees are not efficient, not productive or feeling tired in the afternoon.

    Tiredness was a contributing factor to these disasters:

    > Versailles Train Crash, 1842
    > The Boston Molasses Disaster, 1919
    > De Havilland Comet Plane Crashes, 1954
    > Nuclear Three Mile Island, 1979
    > Alexander L. Kielland Oil Platform, 1980
    > The Chernobyl Nuclear Disaster, 1986
    > The Challenger Space Explosion, 1986
    > The Exxon Valdez Oil Spill, 1989
