Abstract:
Sleep-related problems (SRPs) among adolescents are a growing concern. Theory and research suggest that emotional arousal may have cyclical relation with SRPs, but whether emotional dysregulation plays a role is not clear. We investigated associations between two physiological indices of emotion regulation (video baseline heart rate variability and change in heart rate variability to a stressor) and SRPs in a sample of 80 adolescents (ages 11-17 years; 51% female; 37.5% African American). The findings showed a negative relation between video baseline heart rate variability and SRPs, controlling for non-sleep-related anxiety disorder symptoms (β = -0.29) and general manifest anxiety (β = -0.25). We found no relation between change in heart rate variability to a stressor and SRPs when non-sleep-related anxious arousal was controlled. If replicated, findings illustrate the importance of physiological regulation of emotion influencing (or influenced by) SRPs during adolescence.

Regulation of Heart Rates
The SNS increases heart rate through the release of norepinephrine and epinephrine, which act on beta-1 adrenergic receptors in the heart. This action increases the rate of depolarization in the sinoatrial (SA) node, the heart's...

Cardiac Output I:Effect of Heart Rate on Cardiac Output
Cardiac output (CO) refers to the total amount of blood ejected by one of the ventricles in liters per minute (L/min). In a resting adult, CO ranges from 5 to 6 L/min, adjusting according to the body's metabolic requirements.
Effect of Heart Rate on Cardiac Output
Cardiac output adapts to metabolic demands during stress, physical activity, or illness. The autonomic nervous system regulates heart rate via the sinoatrial node. The parasympathetic nervous system decreases heart...
