Key result
Daily conflict at work was significantly associated with altered nocturnal heart rate variability, specifically parasympathetic function in early sleep.
Why the study?
Stressors such as conflict at work may interfere with sleep, but the relationship between daily conflict at work, work-related rumination, and nocturnal heart rate variability remained to be clarified.
Does daily conflict at work reduce nocturnal heart rate variability in healthcare employees?

Does daily conflict at work reduce nocturnal heart rate variability in healthcare employees?
Daily conflict at work increases off-job rumination and may directly impair parasympathetic function (nocturnal HRV) during early sleep in healthcare workers.

Work conflict may impair early-sleep parasympathetic recovery; hypothesis-generating for occupational stress trials on nocturnal HRV.
Sleep plays an essential role in maintaining employees' health and well-being. However, stressors, such as conflict at work, may interfere with employees' sleep. Drawing on previous literature on the relationship between conflict at work and sleep outcomes, we proposed a negative relationship between daily conflict at work and physiological changes during early sleep, particularly nocturnal heart rate variability (HRV). Furthermore, building on the perseverative cognition hypothesis, we proposed that daily work-related rumination mediates the relationship between conflict at work and nocturnal HRV. Ninety-three healthcare employees participated in a daily diary study for five workdays, resulting in 419 observations. Multilevel analysis revealed a significant relationship between daily conflict at work and nocturnal HRV, specifically high-frequency (HF) power. Daily conflict at work was found to predict rumination; however, rumination did not significantly predict nocturnal HRV. Our results suggest that daily conflict at work increases rumination during the off-job time and may directly alter nocturnal HRV, specifically parasympathetic function in early sleep.

Kerman et al. (2022) reported an observational. Daily conflict at work was evaluated on Nocturnal heart rate variability (HRV), specifically high-frequency (HF) power. Daily conflict at work was significantly associated with altered nocturnal heart rate variability, specifically parasympathetic function in early sleep.
