Tired? It's no surprise: You're just one of 41 million American workers who suffer from lack of sleep, according to a survey of 15,000 people by the Centers for Disease Control.

Indeed, 20% of car accidents are associated with sleepy drivers, and more than 4,500 workers were killed by occupational injuries in 2010. Sleep deprivation is a particular problem for certain kinds of workers. Some 44% of night-shift employees are sleep-deprived; transportation and warehouse workers are hit hardest, with health care and social assistance workers behind them.
