Timing of restricted sleep: mood and neurobehavioral outcomes in healthy sleepers.

ABSTRACT:

Study objective

To evaluate how nocturnal timing of sleep restriction affects vigilant attention and mood in healthy controls with normal sleep-wake patterns.

Methods

A convenience sample from two controlled sleep restriction protocols were used to investigate the difference between 4 hours of sleep early in the night, versus 4 hours late in the night. Volunteers stayed in a hospital setting and were randomized to one of the three conditions: a control (8 hours of sleep each night), an early short sleep (ESS, 2300-0300 hours), and a late short sleep (LSS, 0300-0700 hours). Participants were evaluated with psychomotor vigilance task (PVT) and mood ratings via visual analog scales.

Results

Short sleep conditions led to greater performance decrements than control on PVT.
