| Beschreibung: | Sleep is essential for the homeostasis of various brain and body functions. Timing, duration, and composition of sleep are controlled by internal oscillators. In modern society, sleep timing is largely dictated by environmental factors. There is increasing evidence that a severe mismatch between internal sleep needs and external demands leads to circadian misalignment, which is detrimental to physical and mental health. The aim of the present study was to examine relationships between the amount and timing of sleep/sleep stages on weekdays, body mass index (BMI), and psychosocial stress due to perceived workload in a relatively homogeneous cohort of young and lean healthy adults. We used longitudinal real-life Fitbit (Inspire) sleep data in combination with a questionnaire among first-year medical students (n = 59) and conducted correlation-based network analysis. BMI was within the normal weight range in the sample. A stronger temporal alignment between rapid eye movement (REM) sleep and total sleep and a higher individual variability of sleep timing was associated with higher BMI, which was associated with lower subjective workload. Our data suggest an interaction between sleep timing, in general, and REM sleep timing, in particular, with metabolic homeostasis and resilience to psychosocial stress. | |||||||
