Although estimates depend on how sleepiness is defined (i.e., sleeping too much vs. falling asleep in the daytime), about 16% of adults experience sleepiness that affects their daytime function, and there is increasing evidence that sleepiness plays a part in both industrial and road traffic accidents. The National Highway Traffic Safety Administration estimates that more than 100,000 automotive crashes per year are fatigue related. These sleepiness-related accidents contribute to 40,000 injuries and 1550 deaths per year.1 Over the past two decades, research has provided increased understanding of obstructive sleep apnea (OSA), among other sleep disorders.2
