Autonomic Nervous System Metrics

Meaning

Autonomic Nervous System Metrics are quantifiable measures derived from physiological signals that objectively reflect the functional balance and activity of the body’s involuntary control system, comprising the sympathetic and parasympathetic branches. Key clinical metrics include Heart Rate Variability (HRV), respiratory rate patterns, and skin conductance responses. These non-invasive measures serve as robust, objective proxies for assessing an individual’s allostatic load, inherent stress resilience, and the overall state of neuroendocrine regulation. Clinically, they offer profound, real-time insight into the body’s capacity to effectively adapt to both physical and psychological stressors.
