Odd work hours or overnight shifts may be “the nature of the beast” for trucking, but the detrimental impact on driver health and performance is too profound to ignore, as a sleep expert and a fleet safety manager detailed in a recent FusionHealth webinar. The good news, corporate America is learning, is that a sleep management program can substantially improve employee wellbeing and effectiveness—and quickly.

FusionHealth co-founder and Chief Medical Officer Dr. Jeffrey Durmer opens his presentation by noting the high-profile catastrophes which share fatigue-related causes: the Chernobyl nuclear disaster, the Challenger explosion, and the Exxon Valdez oil spill.

More generally troubling, Americans increasingly suffer from “a culture of getting less sleep,” with research putting the level at 45% of the working population being sleep deprived on a daily basis. And while much of that population simply doesn’t get the sleep they need periodically, a substantial number of people have clinical sleep disorders, including 1 in 3 with insomnia, 1 in 4 with obstructive sleep apnea (OSA) and 1 in 10 with restless legs syndrome.

“Even 1 in 10 is a very large number when you look at your workforce,” Durmer says. “These are problems and disorders that are affecting people on a night-to-night basis and largely going undiagnosed and unaddressed by medical programs.”

In fact, OSA is undiagnosed in around 80% of the people who have it, he notes.

These problems—even after just one night of poor sleep—result in the loss of hormonal appetite regulation (causing weight gain) and toxic waste build-up in the brain, which can be dangerous over the long term. The toll rises to another level of severity for people with undiagnosed disorders, including cardiovascular disease, diabetes, and a much higher mortality risk.

“If we can get ahead of the sleep problem our country has, we may be able to get ahead of the accelerating chronic diseases and the costs associated with them,” Durmer notes.

As for the workplace, sleep deprivation results in a lack of focus, lost work time, more accidents and more errors. Durmer calculates that each sleep-deprived employee typically costs the company an average of eight days in lost productivity compared to well-rested employees.

Indeed, a sleep deprived employee is nearly three times more likely to cause an accident than a well-rested employee, and is 3.6 times more likely to engage in safety compromising behavior, according to researchers.

Specifically, the “executive functions”—processed in the brain’s frontal lobe—are impaired after several hours on task in people with sleep deprivation. Simply, “the A team” hands over control to less capable areas of the brain.

“This increases the mistakes and risks for an organization,” Durmer says. “When you have a sleep-deprived population, this is something that can drive up poor decision making, errors, and costs.”

And corporate American has taken notice. A McKinsey survey from earlier this year found that 70% of executives said sleep management should be taught in organizations, the same way time management and communication skills are taught now.

Durmer recommends a number of specific measures companies can take to help their employees. These include:

  • Integrate population sleep health education as a business principle and create measures to improve the identification and assistance for employees facing these challenges.
  • Assign workers to the shift hours that better align with their natural circadian rhythms.
  • Discourage extended work hours and all-nighters by limiting access to work facilities and equipment when possible.
  • Institute “blackout hours” for work by configuring corporate email servers to not update during certain off hour time periods.
