What is the Origin of Trauma Response?

The term originates from psychology and psychiatry, describing the cognitive, emotional, and behavioral reactions to traumatic stress. Its integration into the hormonal health lexicon reflects the growing clinical understanding of the deep biological embedding of trauma. The chronic physiological changes, particularly HPA axis dysregulation, provide a measurable link between psychological experience and physical health outcomes.

Trauma Response

Meaning

Trauma Response, in a broad clinical and physiological sense, refers to the acute and chronic systemic adaptations that occur following exposure to a physically or psychologically overwhelming event. Physiologically, this involves a profound, prolonged activation of the hypothalamic-pituitary-adrenal (HPA) axis, leading to dysregulated cortisol secretion and altered sympathetic nervous system tone. This chronic activation can lead to systemic inflammation, hormonal imbalances, and a reduced capacity for homeostatic regulation. Understanding the trauma response is critical for addressing its downstream effects on metabolic and endocrine health.
