What is the Origin of Stress Reactivity Attenuation?

This concept is derived from psychophysiology and behavioral medicine, which study the individual differences in stress response and the plasticity of the autonomic nervous system. "Attenuation" emphasizes a deliberate, measurable reduction in the intensity of the fight-or-flight response.

What is the Mechanism of Stress Reactivity Attenuation?

Attenuation is primarily mediated by enhancing the tone of the parasympathetic nervous system, specifically the vagus nerve, which acts as a brake on the SNS. Hormonally, it involves improving the negative feedback sensitivity of the glucocorticoid receptors, allowing for a faster cessation of cortisol release once the stressor is resolved. Techniques like mindfulness and controlled breathing are behavioral tools that directly modulate the autonomic balance, promoting a state of calm resilience.

Stress Reactivity Attenuation

Meaning

Stress Reactivity Attenuation is the intentional physiological and psychological modification aimed at reducing the magnitude and duration of the body’s acute stress response to perceived threats or challenges. This process involves downregulating the rapid activation of the Sympathetic Nervous System (SNS) and the Hypothalamic-Pituitary-Adrenal (HPA) axis, resulting in a quicker return to homeostatic baseline following a stressor. Successfully achieving attenuation is vital for preserving long-term cardiovascular and metabolic health.
