Subjective Socioeconomic Status Moderates How Resting Heart Rate Variability Predicts Pain Response.

ABSTRACT: Higher resting heart rate variability (HRV)-an index of more flexible response to environmental stressors, including noxious stimuli-has been linked to reduced perception of experimentally induced pain. However, as stress responses are adapted to one's chronic environments, we propose that chronic exposure to threats captured by one's subjective socioeconomic status (SSS) may shape different adaptations that produce distinct pain responses linked to higher resting HRV. Specifically, lower SSS individuals with more threat exposures may prioritize threat detection by upregulating sensitivity to stressors, such as acute pain. Therefore, higher HRV would predict greater perceived acute pain among lower SSS individuals. In contrast, higher SSS individuals with less threat exposures may instead
