Fatigue High-risk hours

    National Safety Council

    41% work at high-risk times, during the night or in early morning hours. You don’t have to be a shift worker to be at risk for work scheduling-related fatigue. Any worker who is on-the-job, even occasionally, at night (between 9pm and 6am) or in the early morning hours (between 3am and 7am) can be at risk for fatigue. Not only are they working against their natural body clock, but they’re likely not getting the proper rest. Sleep debt can accumulate faster than we realize. After ten days of losing two hours of sleep per day, our performance is similar to the effects of skipping an entire day of sleep.
