Objectives: Circadian misalignment and sleep deprivation often occur in tandem, and both negatively impact glucose homeostasis and metabolic health. The present study employed a forced desynchrony protocol to examine the influence of extended wakefulness and circadian misalignment on hourly glucose levels.
Methods: Nine healthy adults (4F/5M; 26 ± 4years) completed a 31-day in-laboratory protocol.
Article Synopsis
- The study aimed to see how different light conditions and sleep schedules impact the body’s natural circadian rhythm after advancing sleep by 8 hours.
- Forty-three participants followed an 8-day inpatient program with five different lighting and sleep shift conditions, which included gradual and sudden adjustments.
- Results showed that the combined use of higher illuminance white and green light with a modified shift led to the greatest advancements in melatonin onset and improved sleep quality compared to other methods.
Objectives: The aim of this observational study was to examine sleep obtained between consecutive night shifts from shift workers in their natural environment. The goal was to identify the various sleep strategies and the timing, duration, regularity, and quality of sleep associated with the strategies.
Methods: Participants (N = 33, 23 women, aged 40 ± 15years) reported their sleep information in daily diaries over 2weeks while working at least one series of consecutive night shifts.
Objectives: Facial recognition is one of the key functions of the human brain, and linking a face to a name is critical in many social and occupational settings. This study assessed circadian- and wake-dependent effects on face-name recognition in healthy adults.
Methods: Thirteen healthy adults (20-70years; 7 F) were studied in a 39-day inpatient protocol that included 3weeks of 28 hours forced desynchrony with sleep restriction (6.
