According to the American Council on Science and Health, researchers concluded that sleep loss stemming from two different problems “is strongly associated with motor vehicle crashes in the general population, independent of self-reported excessive sleepiness.”

It’s well known that sleep deprivation contributes to car crashes. We know this – and those at risk, who don’t get enough sleep, know precisely how to correct it.

But what if someone exists in a perpetual sleepy state and doesn’t realize it? Which might mean going through their work week in that fashion, day after day, and frequently getting behind the wheel. This scenario would be one in which there’s increased risk, while nothing’s being done to address it.
