Autonomic Nervous System Assessment

Meaning

Autonomic Nervous System Assessment is a non-invasive clinical method used to quantify the functional balance and responsiveness of the sympathetic (fight-or-flight) and parasympathetic (rest-and-digest) branches. This evaluation provides a window into the body’s internal stress management capacity and its ability to adapt to environmental and physiological demands. Abnormal patterns often reveal underlying chronic stress, sleep debt, or hormonal imbalances that compromise overall health. Clinicians use this assessment to guide interventions aimed at improving resilience.
