Chronic sleep curtailment, even without extended (>16-h) wakefulness, degrades human vigilance performance

This is a data set derived from controlled in-laboratory conditions of individuals exposed to either control (equivalent to a sleep opportunity ~8h) or chronic sleep restricted conditions (equivalent to a sleep opportunity ~5.6h). This study was accomplished using a circadian forced desynchrony design on a 20-h day length. All subjects provided written informed consent prior to participation and all procedures were approved by the Partners Healthcare Institutional Review Board.
