Abstract:
No studies have evaluated the dynamic, time‐varying relationship between delta electroencephalographic ( EEG ) sleep and high frequency heart rate variability ( HF ‐ HRV ) in women. Delta EEG and HF ‐ HRV were measured during sleep in 197 midlife women ( M age = 52.1, SD = 2.2). Delta EEG – HF ‐ HRV correlations in nonrapid eye movement ( NREM ) sleep were modeled as whole‐night averages and as continuous functions of time. The whole‐night delta EEG – HF ‐ HRV correlation was positive. The strongest correlations were observed during the first NREM sleep period preceding and following peak delta power. Time‐varying correlations between delta EEG – HF ‐ HRV were stronger in participants with sleep‐disordered breathing and self‐reported insomnia compared to healthy controls. The dynamic interplay between sleep and autonomic activity can be modeled across the night to examine within‐ and between‐participant differences including individuals with and without sleep disorders.
