At Work At Home On the Road

Fatigue – You're More Than Just Tired

  • ​People often make light of how little sleep they get; an over-worked, over-tired condition has become the norm for many. But a good night's sleep is not just a novelty, it's a necessity. The effects of fatigue are far-reaching and can have an adverse impact on all areas of our lives.

    Our 24/7 Workforce


    Our bodies are programmed to be tired at night and alert during the day, but work often requires us to override those natural sleep patterns. More than 43% of workers are sleep-deprived, and those most at risk work the night shift, long shifts or irregular shifts. Following are a few facts for employers:

    • Safety performance decreases as employees become tired
    • 62% of night shift workers complain about sleep loss
    • Fatigued worker productivity costs employers $1,200 to $3,100 per employee annually
    • Employees on rotating shifts are particularly vulnerable because they cannot adapt their "body clocks" to an alternative sleep pattern

    On the Road


    We wouldn't allow a friend to drive drunk, but we rarely take the keys away from our tired friends or insist that they take a nap before heading out on the road. Drowsy driving is impaired driving. NSC has gathered research that shows:

    • You are three times more likely to be in a car crash if you are fatigued
    • More than 5,000 people died in drowsy-driving related crashes in 2014
    • Losing even two hours of sleep is similar to the effect of having three beers
    • Being awake for more than 20 hours is the equivalent of being legally drunk

    We're Getting Sick Over It


    Adults need an average of seven to nine hours of sleep each night, but 30% report averaging less than six hours, according to the National Health Interview Survey. Sleep is a vital factor in overall health.


    Time for Change


    Americans receive little education on the importance of sleep, sleep disorders and the consequences of fatigue, but industry leaders recently have been drawing attention to this issue. Employers, too, are in an ideal position to educate employees on how to avoid fatigue-related safety incidents.

    Change begins with the individual. The National Safety Council supports science-based fatigue risk management systems in the workplace and recently convened a panel of experts to explore fatigue and its effect on occupational safety. We look forward to sharing the results of this discussion.
