The PVT helps with understanding of the relationship between Psychology and physiolog
- The parasympathetic soothing system (the ventral vagal system, in Porges’ terms) responds to perceived safety and friendly, attuned social contact, and explains the health benefits of social relationships (Porges, 2022; Porges, 2023).
- The development of a resilient calming system primarily depends on attuned attachment experiences and successful co-regulation in the first years of life (Dana & Porges, 2021; Porges, 2021).
- The well-established link between reduced heart rate variability (HRV) and psychological /somatic illnesses (Adam et al., 2023; Ding et al., 2024) is related to an underdevelopment of this system and underscores why polyvagal-informed treatment approaches—such as Somatic Experiencing or Sensorimotor Psychotherapy—are suitable therapeutic modalities for developing autonomic regulation.
For Psychiatrists, psychotherapists and other practitioners
- Easy-to-understand model: The Polyvagal theory provides a helpful framework for self-observation and self-regulation, which can be used to identify phenomena such as mobilization, relaxation, or immobilization.
- Guidance for practitioners: The polyvagal approach provides guidance, as the precise observation of autonomous bodily processes allows conclusions to be drawn about both the patient's physiological state and the practitioner's own. This enables an informed choice of interventions, both in the moment and over the long term.
- Quality assurance of treatment: A polyvagal-informed treatment approach, where exploration focuses on autonomic physiological reactions and what is said, captures the patient's experience better than a purely cognitive-verbal approach.
- Orientation creates safety: Targeted training of neuroception (the unconscious perception of threat and safety) opens up opportunities to align a person’s behavior more on their well-being.
- Self-regulation through targeted activation of the vagus nerve: Polyvagal theory has significantly helped raising awareness of positive effects of the vagus nerve. The theory embodies a fertile ground for the development of new regulation techniques related to vagus nerve stimulation.
- Explanation for the efficacy of therapeutic interventions: Polyvagal theory explains many common practices in psychotherapy and body therapy, such as specific aspects that can establish safety in a relationship or what the benefits of small talk or grounding might be.
For people struggling with mental health
- Coherent framework model for autonomic responses: Most psychiatric patients are looking for healthier ways to deal with overwhelming autonomic physiological responses or emotional states. The Polyvagal theory offers a coherent framework model that links autonomic physiological processes with emotional and social ones.
- Practice-oriented approach to psychiatric suffering: Through the polyvagal lense, phenomena can be observed, understood, classified, and influenced, and suddenly make sense. Concepts such as “perceived safety” or “threat” become tangible and can be placed in a directly perceptible context with physical reactions like “numbness” or “tingling” or linked to behavioral impulses such as “I want to run away.”
- Good starting point for self-regulation and self-efficacy: A polyvagal-informed observation of autonomic microphenomena serves as an innate instrument that not only measures the subjective effectiveness of one's own behavioral interventions, but also provides orientation in a world that can become overwhelming. The more accurately patients perceive these micro-processes within themselves, the sooner they can influence and regulate their own state.
- Strengthening self-efficacy and autonomy: The polyvagal model offers patients a self-evaluative tool for measuring the influence of their behavior on their organism. This allows the formation new neural pathways and healthier habits that are directly related to subjective experience.
- Framework model for self-exploration: The polyvagal approach provides a model for understanding self-exploration, which can be used to improve the connection to the body.
- Polyvagal-informed exercises for everyone: The theory can serve as a basis for developing a better sense of orientation, body connection, and self-regulation. Exercises for internal or external perception or Vagus nerve stimulation can be practiced autonomously.
For parents:
- The polyvagal theory can help parents better understand their children's behavior and respond appropriately.
- Parents learn that emotional outbursts such as tantrums or crying are calls for help with co-regulation and should not lead to the child's isolation.
- Emotional outbursts in children (and adults) are not manipulative performances, but an expression of being overwhelmed by emotion regulation.
- The parents' task in such moments is to modulate the child's nervous system through their calm, attuned, physical presence and to send signals of acceptance, connection, and safety.
- The theory enables parents to reflect on and adjust their own reactions to their children's states.
Acknowledgement
- Although the anatomical hypotheses of the theory could not be scientifically confirmed (Menuet, 2025; Grossman, 2024), it must be acknowledged that many important recent advances in trauma therapy would not have been possible without Stephen Porges' interdisciplinary contribution.
- Porges is one of the few researchers who has dared to formulate a comprehensive theory of stress and trauma that takes subjective and objective aspects into account and links them to neurobiology and anatomy.
- It is not surprising that most of today’s leading trauma therapists appreciate the polyvagal theory as a valuable, practical conceptual framework that is enthusiastically received by patients.
