title: Level of stress and sleep duration.
abstract: 30 subjects kept daily diaries of sleep-duration and stress levels for 4 mo. From these data, it was determined that during periods of high stress, sleep was reduced by about one standard deviation while during periods of low stress, sleep increased by about one-half a standard deviation. The relationship of these results to the relevant sleep-stress literature was briefly discussed.
