Interoception
The body continually informs the brain.
Shrink Definition
Interoception is the process through which the brain detects, interprets, and integrates signals arising from within the body. These signals include information related to heartbeat, breathing, hunger, thirst, temperature, pain, muscle tension, gastrointestinal sensations, and many other internal physiological processes. Interoception contributes to emotional experience, self-awareness, homeostasis, and adaptive behavior.
Plain language
Your brain is constantly listening to your body.
Shrink Insight
Many emotions include both psychological and physiological components.
Why it matters
Interoception contributes to: • emotional awareness • anxiety • hunger regulation • pain perception • stress responses • homeostasis • self-awareness
Common misunderstanding
Interoception isn't simply "paying attention." It refers to specific neural processes involved in sensing internal bodily states.
Shrink Perspective
The mind and body continuously exchange information.
Shrink Reflection
Which bodily sensations do you notice most easily? Which do you rarely notice?
Shrink Journal
Spend five minutes observing your breathing, heartbeat, posture, and muscle tension without attempting to change them.
Shrink Step
Notice one internal bodily sensation before reacting emotionally.
Shrink Minute
Listen inward.
Shrink Takeaway
Awareness begins inside the body.
Medical boundary
This concept is educational and shouldn't be used to self-diagnose. It doesn't replace care from a licensed clinician. Symptoms, medication, and treatment decisions should be discussed with a qualified professional, and emergency symptoms require emergency care.
Evidence summary
Interoception is a foundational concept in neuroscience, physiology, psychiatry, and affective science. Research supports its role in emotional experience, bodily awareness, homeostatic regulation, and adaptive behavior. Medical Boundary Altered interoception has been studied in numerous neurological, psychiatric, and medical conditions. Interpretation of bodily sensations should always consider the possibility of underlying medical illness.
