HRV & Interoception

HRV Biofeedback May Be Improving More Than Heart Rate

For years, heart rate variability (HRV) has been used as a marker of autonomic nervous system function. Most conversations have focused on whether someone can increase their HRV through breathing exercises or biofeedback. Emerging research in 2026 suggests something even more interesting: HRV biofeedback may not simply improve physiological regulation — it may also strengthen interoception, the ability to accurately recognize and interpret signals coming from within the body.
