Neurobehavioral dynamics following chronic sleep restriction: dose-response effects of one night for recovery

What the research tells us
After five restricted nights, greater recovery sleep opportunity improved five of six neurobehavioural measures in a dose-related manner. Yet even a ten-hour opportunity did not restore sustained attention, subjective sleepiness and fatigue fully to baseline. Recovery depended on the outcome measured.
Scope & interpretation
A controlled single-night experiment cannot determine recovery after weeks of restriction, in clinical populations or for an individual. Time in bed differs from actual sleep, and comparisons with baseline differ from comparisons with controls.
Study at a glance
- POPULATION & SAMPLE
- 159 healthy adults: 142 in restriction and 17 controls, with smaller groups at each recovery dose.
- EXPOSURE / INTERVENTION / SUBJECT
- Two ten-hour baseline nights, then five four-hour nights followed by one randomized recovery opportunity of 0, 2, 4, 6, 8 or 10 hours; controls retained ten-hour opportunities.
- OUTCOMES
- Dose-related attention, sleepiness, fatigue and other neurobehavioural measures. The ten-hour recovery group slept approximately 8.96 hours.
- TIME FRAME
- Five restricted nights and one recovery night; no estimate of multi-night recovery effects.
