An estimated 30% of all US workers — more than 40 million people — report sleeping fewer than six hours per night, which meets the National Sleep Foundation’s criteria for sleep deprivation. Seven to nine hours of sleep is recommended for optimal health. People who work in manufacturing were the most likely to be sleep deprived, especially if they worked night shifts. Black workers, Asian workers and “other” race workers were more likely to report sleeping fewer than six hours per night, compared with white or Hispanic workers.
