Using Acoustic Stimulation to Improve Recovery Sleep and Performance After Sleep Deprivation in Adults Aged 18 to 39

What this Trial Is About

Researchers are evaluating whether brief sounds or tones played during a limited recovery sleep period after 40 hours of sleep deprivation can enhance the restorative effects of sleep and improve performance during the following awake period. This study involves healthy adults aged 18 to 39 and aims to understand how acoustic stimulation during slow-wave sleep affects alertness and cognitive functions. Participants will experience two nights of approximately four-hour recovery sleep after sleep deprivation. During these recovery sleeps, one group will receive acoustic stimulation via the Philips SmartSleep device during slow-wave sleep, while the other group will receive sham treatment without acoustic stimulation. The device is applied prior to bedtime on both recovery nights to deliver or withhold the acoustic signals. Throughout the study, participants performance and alertness will be assessed using various tests including the Psychomotor Vigilance Task, mathematical processing tests, mood scales, and sleepiness scales over several days. Sleep and wakefulness will also be monitored via polysomnographic recordings and actigraphy. The study includes safety monitoring and adherence checks, with total participation spanning multiple days to capture effects during and after sleep deprivation and recovery.
