Changes in sleep architecture during recurrent cycles of sleep restriction: a comparison between stable and variable short sleep schedules.

ABSTRACT:

Study objectives

To examine how sleep architecture changes over successive cycles of restricted and recovery sleep in young adults, and to determine whether sleep-restricted schedules with differing night-to-night variability in sleep durations lead to different sleep physiological responses.

Methods

In this 15-night laboratory-based study, 52 healthy young adults (25 males, age: 21-28) were randomly assigned to one of three sleep schedules: stable short, variable short, or control. They underwent two baseline nights of 8-h time-in-bed (TIB), followed by two cycles of "weekday" sleep opportunity manipulation and "weekend" recovery (8-h TIB). During each manipulation period, the stable short sleep and the control groups received 6-h and 8-h TIBs each night, respectively, whil
