What the study found
Supine high-frequency HRV during brain imaging did not show a change attributable to the sleep-deprivation intervention.
Scope & limitations
40 healthy young men: 20 assigned to sleep deprivation and 20 to normal sleep.
The protocol and metric are specific; a null intervention result does not mean sleep loss is harmless, and supine high-frequency HRV is not wearable overnight RMSSD. Baseline group differences also require care.
Population & sample
40 healthy men, 20 per randomized condition.
Exposure or intervention
Total sleep deprivation versus normal sleep, with repeated supine recordings during an imaging protocol.
Outcomes
High-frequency HRV and its changes across measurement times and conditions.
Time frame
An acute 24-hour sleep-deprivation protocol.
Research funding
Novo Nordisk Foundation grant NNF16OC0019856.
Research conflicts of interest
The authors declared no competing interests.
