According to a national poll administered by the American Sleep Foundation, more than one-third of the U.S. workforce report daytime sleepiness, which amounts to approximately 5.7 million individuals, or roughly the entire population of Denmark.*
Fatigue and sleepiness are considered serious workplace hazards. They are different, but can be experienced together. Sleepiness refers to the neurobiological need to sleep (you know that feeling when you just can’t hold your head up), while fatigue is a result of prolonged mental or physical exertion. When you are fatigued, you don’t have enough energy to do work or finish a certain activity.**
Stephanie Betz, RPSGT, Administrative Director, Lehigh Valley Hospital Sleep Disorders Centers, points out there are a range of reasons why employees may be deprived of the recommended eight hours of sleep. She says insufficient sleep time and circadian influences are culprits, as are advanced or delayed sleep phases, shift work, or medical conditions. “Sleep quantity is just as important as the quality,” says Betz. “You may get enough sleep, but the quality may be poor due to sleep disorders.” Common ones include obstructive sleep apnea, insomnia, periodic limb movements, restless legs syndrome, and narcolepsy.
Typical effects of sleepiness and fatigue are a decreased motivation to complete tasks, longer reaction time, less alertness, impaired concentration, problems in memory and information processing, and poor judgment.** Unfortunately, these effects are associated with unfavorable events, from industrial disasters and road accidents to increased health care costs and a reduction in overall wellness, performance, and productivity.
To understand everyday worksite risks, it’s worthwhile to look at data from the National Health Interview Survey. The estimated annual injury incidence rate per 100 workers is 7.89 for U.S. workers who usually sleep less than five hours per day, compared with 2.27 per 100 workers among those who tend to sleep between seven and eight hours.*** Employers end up paying the price for these statistics. Costs attributed to fatigue-related, health-related lost productive work time from accidents and injuries stack up to an estimated annual cost of $136.4 billion according to the United States Occupational Safety and Health Administration (OSHA).
LVHN’s Betz says that employers can assist employees in the quest for more and better sleep, or at least can provide accommodations for those who may be at risk for sleep deprivation. She offers a number of considerations that may help mitigate accidents related to sleepiness and fatigue – either on the job or as employees travel to-and-from work.

“When you sacrifice sleep, your energy levels, judgement, attention, and memory all suffer. In one study, sleep deprivation was found to have similar effects as being under the influence of alcohol as far as judgement and reflexes. The Department of Transportation estimates 1,550 fatal car crashes and 40,000 non-fatal crashes a year are caused by drowsy drivers. And people who are sleep deprived don’t even realize they are functioning at a lower or possibly unsafe level.” –Christie Lanasa, CHWC, RN, Ed.S, NBC-HWC, Health Coach, BeneFIT Corporate Wellness/Populytics
