In Episode 24 of the Heart Rate Variability Podcast, we explore five recent studies that span trauma recovery, personality theory, migraine prediction, heart failure monitoring, and fundamental vagal sensory mechanisms. Together, these papers deepen our understanding of HRV not as a static metric, but as a dynamic signal shaped by interoception, context, and time.
This episode emphasizes HRV as a marker of felt safety, autonomic integration, and physiological sensing, highlighting how vagal activity reflects not only brain-mediated regulation but also incoming sensory information from the body. Implications are discussed for clinicians, researchers, and individuals seeking a more nuanced and compassionate understanding of nervous system function.

From Somatic Experiencing to felt safety: Assessing the effects of a body-oriented intervention in adults with various degrees of child maltreatment
Authors:

Monique C. Pfaltz
Journal:
European Journal of Psychotraumatology
Publication Year:
2026
Key Points:
• A brief Somatic Experiencing–based intervention significantly increased psychological safety
• Participants showed improvements in affect and social connectedness
• Heart rate decreased, and HRV increased during the intervention
• Reductions in disrupted body boundaries and increased interoceptive awareness were observed
• Findings support felt safety as an embodied, physiologically measurable state

Integrating autonomic and affective pathways in borderline personality disorder: The triangle therapy hypothesis
Author:
Daniel Juraszek
Journal:
Frontiers in Psychology
Publication Year:
2026
Key Points:
• Proposes a somatic pre-phase intervention targeting autonomic regulation
• Centers on exposure to silence, sound, and isolation as ancestral affective conditions
• Frames BPD as a disorder of autonomic-affective integration rather than cognition alone
• Suggests HRV as a physiological marker of treatment readiness and integration
• Emphasizes bottom-up tolerance before top-down therapeutic work
