Combat-related stress is associated with autonomic nervous system (ANS) dysregulation-sympathetic predominance, reduced vagal tone, and decreased heart rate variability (HRV)-linked to increased cardiovascular risk. Non-pharmacological interventions targeting autonomic regulation show promise, but controlled studies in combat-exposed populations remain limited. We assessed whether adding a...
