Fatigue

  • A recent study measuring sleep, reaction time, sleepiness and driving performance found that drivers who began their work week with just one nighttime period of rest instead of two exhibited more lapses of attention (especially at night), reported greater sleepiness (particularly toward the end of their duty periods), and showed increased lane deviation in the morning, afternoon and at night.1
  • Studies have shown that up to 28% of Commercial Vehicle Drivers may have Obstructive Sleep Apnea.2
  • According to the Canadian Sleep Society, obstructive sleep apnea is extremely common. Estimates show that 24% of middle-aged men and 9% of middle-aged women have it.3
  • An estimated 858,900 Canadian adults 18 years and older reported being told by a health professional that they have sleep apnea.4
  • According to the Canadian Sleep Society, reaction time is more impaired in patients with untreated obstructive sleep apnea than healthy individuals who are legally intoxicated.3
  • A 2010 study published in the Journal of Environmental and Occupational Medicine reported fatigue-related productivity losses due to sleep disorders amount to nearly $2,000 per employee in the United States.5
  • A 2012 Sleep in America poll for the U.S. National Sleep Foundation found that 26% of train operators, 23% of pilots, 15% of truck drivers and 10% of bus/taxi/limo drivers said sleepiness impacted their job performance at least once a week.6
  • According to that same poll, 20% of pilots, 6% of truck drivers, 9% of train operators and 7% of bus/taxi/limo drivers reported making a serious error at work due to sleepiness.6
  • In the U.S., the Federal Motor Carrier Safety Association found that drivers who suffer from obstructive sleep apnea are 2-7 times more likely to get in a crash.7
  • A U.S. study has found that continuous positive airway pressure (CPAP) in patients with obstructive sleep apnea (OSA) is associated with reductions in mortality, even when only used minimally. Objective monitoring of the CPAP device over 1 to 3 months showed that each hour of CPAP use was associated with a 29% reduction in mortality risk.8
