Psycho-Physiological Interdependence

Meaning

Psycho-Physiological Interdependence is the foundational concept recognizing that the mental and emotional state (psychological) of an individual is inextricably linked to and mutually influences their physical and hormonal state (physiological), particularly within a close dyadic relationship. This interdependence extends the mind-body connection to a shared, relational level, suggesting that one partner’s chronic anxiety can lead to measurable physiological dysregulation in the other. It is a critical lens for understanding complex health outcomes in couples. This holistic view guides integrative clinical practice.
