What Is Interoception, Exactly?
Interoception is the nervous system's sense of the body's internal state. What it does, why predictive processing needs it, and why some people feel it more clearly than others.

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.

What Is Human Experience, in the Nervous System?

Why Do I Feel Things in My Body Before My Mind Catches Up?
Interoception — the perception of internal bodily states — often precedes conscious cognition. What arrives as a feeling in the chest or a knot in the stomach is a signal the brain is still translating into words.
