An interventional study of Chronic sleep restriction and driving simulator in Sleep Deprivation, sponsored by University Hospital, Bordeaux. Completed at 2 sites in France. Open to male participants aged 20 Years to 55 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-06-01.
Sponsored by University Hospital, Bordeaux · Not applicable, Interventional, and Health services research
Young subjects and patients with nocturnal respiratory disorders are frequently involved in sleep-related accidents. This study assess the impact of chronic sleep restriction (4 hr of sleep during 5 days) or total sleep deprivation in young or mature healthy subjects or snorers on simulated driving, objective and subjective sleepiness and objective and subjective cognitive performances. The effects of recovery night on these parameters are also assessed.
Principal objective :
To determine whether chronic sleep restriction affects more snorers driving performances than healthy subjects' driving performances.
To determine whether chronic sleep restriction affects more young people driving performances than mature subjects' driving performances.
Secondary objective :
To determine whether chronic sleep restriction affects more snorers reaction time performance and sleepiness than non snorers subjects'.
To determine whether chronic sleep restriction affects more young people reaction time performance and sleepiness than mature subjects'.
To determine how age and snoring intensity affects the degradation of performance over the 5 days of sleep deprivation.
To determine age-related changes in the time course of sleepiness during 5 days of chronic sleep restriction.
To compare the impact of total sleep or chronic sleep restriction on driving performances according to the age and snoring intensity.
To determine recovery facilities to chronic sleep restriction according to the age and snoring intensity.
