Implication

Supports stage-specific HRV interpretation in sleep research; leaves open whether targeting REM sympathetic surges alters outcomes.

Key Points

To assess state-specific autonomic nervous system regulation during wakefulness, NREM sleep, and REM sleep using power spectral analysis of heart rate variability.
Assessed autonomic nervous system modulation across wakefulness, NREM sleep, and REM sleep stages in humans.
Applied power spectral analysis of heart rate variability to quantify sympathetic tone and parasympathetic (vagal) activity.
NREM sleep exhibited distinct autonomic modulation marked by high parasympathetic activity.
REM sleep demonstrated attenuated vagal tone and significantly augmented sympathetic activation.
Wakefulness presented an intermediate autonomic profile, showing lower parasympathetic tone and higher sympathetic activity than NREM, but the reverse pattern relative to REM sleep.
