Stress exposure increases risk for depressive symptoms. However, there are substantial individual differences in affective responses to stress. High-frequency heart rate variability (HF-HRV), a marker of vagally-mediated parasympathetic activity, has been conceptualized as a psychophysiological index of emotion regulation that may moderate individuals' responses to stress.

However, there exist significant individual differences in sleep reactivity, which is the extent to which one experiences sleep disturbances in response to stress.
Purpose: The aim of the current study was to investigate whether low high-frequency heart rate variability (HRV), as a psychophysiological marker of poor emotional and physiological arousal regulation, predicts stress-related sleep disturbances associated with greater risk of depression symptoms.
Article Synopsis
- Close relationships play a vital role in shaping emotional experiences and regulation between partners, influenced by individual self-regulatory abilities and social skills.
- This study investigated how respiratory sinus arrhythmia (RSA), a marker of self-regulation, affects the relationship between rumination (a negative emotional strategy) and conflict in couples, specifically focusing on 83 cohabiting partners with young children over 12 months.
- Results showed that rumination from both partners contributed to ongoing conflicts, but higher RSA in one partner helped reduce the negative impact of their partner's rumination on couples' conflict, emphasizing the interconnected nature of emotion regulation in relationships.
Article Synopsis
- Respiratory sinus arrhythmia (RSA) is a measure of cardiac vagal tone that influences social functioning and may affect how individuals cope with stress in relationships.
- Recent research indicates that RSA can moderate the relationship between dyadic coping (DC) and depressive symptoms among partners.
- The study found that men with lower RSA experienced a stronger link between negative DC and their depression, while those with higher RSA showed a protective effect from positive DC, suggesting that higher RSA may enhance social skills that help mitigate negative feelings during stressful interactions.
Sleep is a basic biological process supporting emotion regulation. The emotion regulation function of sleep may be particularly important in the context of chronic stress. To better understand how chronic stress and sleep interact to predict mood, 66 parents of children with autism completed daily diaries assessing parenting stress, negative mood, and sleep quality for 6 consecutive days.

Dyadic coping, a spousal support process in which members of a couple work together to cope with the stressors that 1 or both partners are facing, is associated with higher marital satisfaction and reduced psychological distress. The goal of the present study was to evaluate whether dyadic coping is also related to systemic inflammation among individuals facing chronic parenting stress.
