"Body intelligence" sounds like a metaphor — but there's real, mapped neuroscience behind the idea that your body genuinely informs how you think and decide.

Neuroscience calls this interoception: the brain's sensing and processing of the body's internal physiological state. Antonio Damasio's somatic marker hypothesis proposes that interoceptive cues, emerging into consciousness via the insula, play a real role in instinctive, pre-conscious judgment. A.D. Craig's anatomical work mapped exactly how these signals travel from body to brain, and fMRI research has directly demonstrated overlap between interoceptive awareness and emotional processing in the insula.

This guide grounds "body intelligence" in that real research, and covers what it means for how you make decisions and relate to your own body.
