What is interoception in neurodivergent nervous systems?
Interoception is the bridge between your nervous system and conscious awareness. Interoception isn’t self-awareness or emotional intelligence you build through mindfulness practice. It’s your nervous system’s capacity to make internal physiological signals consciously accessible — heart rate, hunger, bladder fullness, fatigue, emotional states manifesting as physical sensations — operating as the bridge between your inner being and the consciousness inhabiting it.
Interoception is the physiological process through which internal bodily signals — including cardiovascular, respiratory, gastrointestinal, genitourinary, and affective states — become available to conscious awareness, enabling recognition and response to the body’s regulatory needs and forming the foundation for emotional awareness and self-regulation.
Frequently asked questions about neurodivergent interoception
What is the difference between interoception and proprioception?
Proprioception detects your body’s position and movement in space through receptors in muscles, tendons, and joints, telling you where your limbs are without looking and how you’re moving. Interoception detects your internal physiological state — hunger, heart rate, bladder fullness, temperature, emotional states as bodily sensations. Proprioception answers “where is my body?” while interoception answers “how is my body?” The systems use different neural pathways and can be impaired independently, though they sometimes overlap (muscle tension bridges both systems). Many neurodivergent individuals experience challenges in both domains — poor proprioception manifesting as clumsiness or coordination difficulties, poor interoception manifesting as missing hunger, fatigue, or emotional signals. Understanding them as distinct systems helps identify specifically which processing is impaired and what interventions might help.
Can you improve interoception if you're autistic or ADHD?
Yes, but improvements are typically modest and don’t eliminate the underlying neural processing differences. Research shows deliberate interoceptive training — body scanning, heartbeat tracking, structured attention to internal signals — can improve accuracy somewhat, particularly for cardiac interoception which tends to respond most readily to practice. However, neurodivergent individuals generally don’t reach neurotypical baseline accuracy even with extensive training, and gains in one interoceptive dimension (like heartbeat detection) don’t automatically transfer to others (like hunger or emotional awareness). More importantly, improvement isn’t the only goal. Building accurate understanding of which signals you can detect, which arrive with delay, and which rarely reach consciousness allows you to create compensatory structures — scheduled meals instead of waiting for hunger, regular check-ins instead of waiting for fatigue signals. Interoceptive skill means operating effectively with your system’s actual architecture, whether accuracy improves significantly or not.
Why do I not notice I'm hungry until I'm shaking?
Your gastric interoceptive system isn’t transmitting hunger signals to consciousness with sufficient clarity or intensity until blood sugar has dropped critically. The physiological state of hunger exists well before you consciously register it — your stomach is contracting, hormone levels are shifting, blood sugar is dropping — but the neural pathways that should make those signals conscious aren’t functioning with the sensitivity needed to reach awareness at moderate intensity. This isn’t memory failure or inattention to basic needs. It’s impaired interoception, common in autistic and ADHD populations, where the bridge between your body’s physiological state and your conscious awareness doesn’t transmit information effectively until signals reach extreme levels. The solution isn’t “paying better attention” — it’s eating on schedule regardless of hunger signals, removing your dependence on an interoceptive system that doesn’t provide timely information. This is adaptation to your actual architecture, not admitting defeat.
How does interoception affect emotional regulation?
Emotions generate characteristic patterns of physiological activity — cardiovascular changes, respiratory shifts, muscle tension patterns, gut sensations, temperature variations. Interoception detects these physical changes, and your brain interprets them as emotions. If interoception is impaired, you can’t detect the physiological signals that define emotional states, meaning you don’t know what you’re feeling until the emotion builds to overwhelming intensity. This makes regulation nearly impossible because effective regulation requires early intervention — detecting anxiety when it first emerges allows you to employ coping strategies, but by the time impaired interoception finally transmits “I’m anxious” to consciousness, you’re already in full sympathetic activation where regulation is far harder. Additionally, many regulation strategies assume you can identify what you’re feeling clearly enough to work with it. Approaches like cognitive reappraisal or mindfulness observation require knowing your emotional state, which impaired interoception prevents. Coherent emotional regulation for neurodivergent individuals requires acknowledging interoceptive limitations and building approaches that don’t depend on subtle emotional awareness — scheduled regulation rather than reactive regulation, environmental structuring rather than internal monitoring.
Is poor interoception why I forget to use the toilet?
Yes. Impaired bladder interoception means the signals indicating bladder fullness don’t reach consciousness with typical clarity or timing. Your bladder is filling normally, sending signals through the usual pathways, but those signals aren’t being transmitted to conscious awareness effectively. You don’t receive the graduated sense of increasing need that prompts neurotypical individuals to use the toilet proactively — instead, the signal reaches consciousness suddenly when bladder fullness approaches maximum capacity, creating urgent need with no warning build-up. This isn’t forgetting in the conventional sense (you didn’t have the information to remember), and it’s not poor planning. It’s late-arriving or absent interoceptive transmission. Addressing this requires scheduled toilet use regardless of perceived need, establishing external structure that compensates for internal signals you don’t receive reliably. This is accommodation to your nervous system’s actual functioning, not training yourself to pay better attention to signals that aren’t reaching consciousness in the first place.
What is interoceptive accuracy and how is it measured?
Interoceptive accuracy is objective performance on tasks measuring your ability to detect internal signals correctly, regardless of your confidence in those detections. The most common measurement is the heartbeat tracking task: you count your heartbeats over a period (typically 25-60 seconds) without taking your pulse or using external aids, then your count is compared to actual heartbeat data from physiological monitoring. Accuracy is calculated as the correspondence between your perceived count and actual heartbeats. Other measures include water load tests (detecting stomach distension), respiratory load detection (noticing breathing resistance), and various protocols measuring detection thresholds for internal sensations. Research consistently shows autistic individuals demonstrate lower interoceptive accuracy than non-autistic populations across multiple dimensions. This is measurable neural difference, not subjective experience — you can test whether someone accurately detects their heartbeat regardless of whether they believe they can. Understanding your actual accuracy (versus your confidence in your interoceptive abilities) allows you to build compensatory structures appropriate to your real capabilities rather than assumed ones.
Can anxiety cause poor interoception or does poor interoception cause anxiety?
Both directions exist and often create feedback loops. Anxiety can narrow your attention to specific internal sensations (like heartbeat) while impairing your ability to detect other signals (like hunger or fatigue), creating temporarily reduced interoceptive accuracy across some dimensions. Simultaneously, poor baseline interoception can generate anxiety because you operate without clear information about your internal state — you don’t know if you’re hungry, tired, or emotionally dysregulated, creating uncertainty and loss of control that manifest as anxiety. Additionally, some individuals with low interoceptive accuracy misinterpret the normal bodily sensations they do detect, perceiving harmless cardiac variations as dangerous, which amplifies anxiety. For neurodivergent individuals, the relationship is often complex: baseline interoceptive impairment creates chronic uncertainty about internal state, this uncertainty generates anxiety, the anxiety further impairs interoceptive processing in some domains while creating hypervigilance in others, perpetuating both problems. Addressing this requires working with both systems — building interoceptive accuracy where possible while addressing the anxiety that emerges from operating without clear internal information.
How does interoception relate to self-awareness?
Interoception is foundational to many forms of self-awareness, particularly awareness of your current physiological and emotional state. You cannot be aware of being hungry, tired, stressed, or emotionally dysregulated if interoception doesn’t transmit those internal signals to consciousness. However, self-awareness also includes cognitive and social dimensions that don’t depend on interoception — knowing your values, understanding your behavioural patterns, recognising your impact on others. Impaired interoception specifically limits awareness of your body’s current state, not awareness of yourself as a person with history, identity, and agency. The conflation between these types of awareness creates problems when people interpret interoceptive impairment as general lack of self-awareness, suggesting neurodivergent individuals who struggle to detect hunger or emotions also lack insight into their personalities or choices. This is false equivalence. You can have sophisticated understanding of your psychological patterns, values, and behaviour while having poor access to real-time information about your physiological state. Building coherence requires distinguishing which aspects of self-awareness you have and which require compensatory structures due to interoceptive limitations.
What's in this glossary entry
Interoception, defined
Interoception is how signals from your nervous system (your “inner being”) become available to your conscious awareness. This is the bridge between the autonomous nervous system that’s managing your physiology and the consciousness trying to navigate the world. When interoception functions well, you receive clear information about your internal state: you notice hunger before it becomes painful, you detect fatigue before exhaustion, you recognise the early signs of dysregulation before crisis.
The term combines “intero-” (within, internal) with “reception” (the act of receiving). Unlike exteroception, which detects information from outside your body through the five familiar senses, interoception receives information from inside — the state of your organs, your cardiovascular system, your digestive tract, your bladder, your muscles, your hormonal fluctuations, and the physiological signatures of emotional states.
This isn’t abstract. Interoception operates through dedicated neural pathways that carry information from internal organs and physiological systems up through the spinal cord to specific brain regions, particularly the insula and anterior cingulate cortex, where internal signals can be processed and made available to conscious awareness. You’re not thinking yourself into awareness of hunger or heart rate — your interoceptive system is transmitting actual physiological data to consciousness.
Critically, interoception doesn’t create the physiological states it detects. Your heart is beating, your stomach is contracting, your bladder is filling, your stress hormones are rising — all of this happens whether you consciously register it or not. Interoception is the system that makes some of that ongoing physiological activity accessible to conscious awareness so you can respond appropriately.
When this bridge functions well, you operate with accurate information about your internal state. You eat when hungry, rest when tired, use the toilet when needed, regulate before dysregulation reaches crisis. You can identify emotions as they emerge because you detect the physical sensations that accompany them — the tight chest of anxiety, the heavy limbs of sadness, the racing heart of excitement.
When interoception is impaired — as it commonly is in autistic and ADHD individuals — you lose access to signals your nervous system is sending. The data is being generated, the physiological changes are occurring, but the bridge isn’t transmitting that information effectively to conscious awareness. You don’t notice you’re hungry until you’re shaking. You don’t realise you need the toilet until it’s urgent. You don’t detect rising stress until you’re already in meltdown.
Interoception in neurodiversity discourse
Impaired interoception reframes experiences that are often misinterpreted as poor self-care, executive dysfunction, or just lack of awareness. When neurodivergent people say “I forgot to eat” or “I didn’t realise I needed the toilet,” that’s not memory failure or inattention to basic needs — it’s a communication breakdown between the inner being managing physiology and the conscious awareness trying to navigate daily demands.
Research consistently demonstrates that autistic individuals show reduced interoceptive accuracy compared to non-autistic populations. This isn’t about intelligence or self-awareness capacity — it’s about the bridge between nervous system and consciousness functioning differently. The stomach is contracting with hunger, the bladder is filling, the stress response is activating, but those signals aren’t reaching conscious awareness with the clarity or intensity that prompts action.
This has profound implications. Interoception isn’t just about knowing when to eat or use the toilet. It’s foundational to emotional awareness. Emotions generate physiological signatures — changes in heart rate, breathing patterns, muscle tension, gut activity, temperature regulation. If you can’t detect those physical sensations, you also can’t identify what you’re feeling until the emotion is overwhelming. By the time your conscious mind registers “I’m anxious” or “I’m angry,” your inner being has been signalling that state for minutes, hours, or even days.
Understanding interoception as a neural system rather than a skill you develop through better self-awareness changes everything. You’re not failing to pay attention to your body. Your nervous system’s bridge between physiology and consciousness is transmitting information differently than the neurotypical standard, requiring different approaches to access that data.
This also explains why many neurodivergent people describe alexithymia — difficulty identifying and describing emotions. If emotions manifest as physical sensations, and your interoceptive system doesn’t transmit those sensations clearly to consciousness, you’re trying to identify feelings without access to the physiological information that defines them. You might know something feels wrong without being able to name what, because the bridge that should be carrying that information isn’t functioning with neurotypical clarity.
Critically, impaired interoception compounds every other challenge neurodivergent individuals face. Without clear access to internal signals, you can’t regulate effectively because you don’t receive early warning signs of dysregulation. You can’t pace yourself because you don’t detect fatigue building. You can’t manage sensory input proactively because you don’t notice sensory processing overwhelm accumulating. You operate without the feedback system neurotypical individuals unconsciously rely on to modulate their engagement with the world.
The work isn’t developing better self-awareness through mindfulness or body scans, though obviously these can help. The fundamental requirement is recognising that your interoceptive system functions differently, accepting that you won’t automatically receive internal signals the way others do, and building external structures that compensate for signals you don’t receive naturally — scheduled meal times instead of waiting for hunger, regular breaks instead of waiting for fatigue, environmental monitoring instead of waiting for overwhelm, etc.
How to use interoception in a sentence?
“My impaired interoception means I don’t receive hunger signals until I’m already dysregulated from low blood sugar.”
“Understanding that autism affects interoceptive accuracy explained why I could never identify my emotions until they were overwhelming.”
“Building interoceptive skills doesn’t mean I’ll suddenly receive signals like a neurotypical system sends, but that a neurotypical mind unconsciously modulates for — it means learning to detect the subtler cues my system does transmit, and consciously modulating based on that information. There are some extra steps for me as I am neurodivergent, but through understanding interoception I now get it completely.”
The key concepts in interoception
The neural pathways of internal awareness
Interoception operates through specific anatomical pathways carrying information from your organs and physiological systems to your brain. These aren’t metaphorical bridges — they’re actual neural structures with measurable activity that neuroscience can track and study.
The primary pathway runs through the lamina I spinothalamocortical system. Specialised receptors throughout your body — in your cardiovascular system, digestive tract, respiratory system, bladder, muscles, and skin — detect internal states and transmit that information via dedicated nerve fibres up through the spinal cord. This information travels to the thalamus (your brain’s sensory relay station) and then to the insular cortex, particularly the posterior insula, which processes basic interoceptive signals.
From there, information flows to the anterior insula, which integrates these signals with emotional and cognitive processing, and to the anterior cingulate cortex, which links interoceptive information with decision-making and behavioural response. This cascade determines whether internal signals reach conscious awareness and how you interpret and respond to them.
The vagus nerve provides another critical pathway, carrying information from your organs directly to the brainstem. This pathway handles much of the automatic regulation that never reaches consciousness nor ever requires its direct presence or intervention — adjusting heart rate, managing digestion, modulating inflammation — but it also feeds information upward that can become consciously accessible when signals are strong enough or when you deliberately attend to them.
What matters here is that interoception isn’t vague or mystical. It’s a measurable physiological system with identifiable structures that can function more or less effectively. When neuroscientists study interoceptive processing, they can literally see different patterns of activation in these brain regions between individuals with high versus low interoceptive accuracy, and between neurotypical and neurodivergent populations.
Research using functional MRI shows that autistic individuals demonstrate reduced activation in the insula and anterior cingulate cortex during interoceptive tasks compared to non-autistic controls. This suggests that the neural processing of internal signals functions differently at a fundamental level — not because autistic people aren’t trying to pay attention, but because the brain regions responsible for making internal signals conscious are processing information through different patterns.
This neural reality explains why you can’t simply “become more aware” of your body through effort alone. The pathways transmitting internal information to consciousness are operating with different baseline characteristics. Building interoceptive skill requires working with your system’s actual architecture, not forcing it to function like a system with different neural processing patterns.
Interoceptive dimensions and what they detect
Interoception isn’t a single unified system — it processes multiple dimensions of internal information simultaneously, each providing different data about your physiological state.
Cardiac interoception tracks your heartbeat, heart rate, and cardiovascular activity. The ability to accurately detect your own heartbeat without external feedback is one of the most studied interoceptive capacities because it’s measurable and correlates with broader interoceptive accuracy. Research shows autistic individuals typically demonstrate lower cardiac interoceptive accuracy than non-autistic individuals, often unable to count their heartbeats accurately or distinguish their actual heart rate from external rhythmic stimuli. This matters because cardiac awareness provides continuous feedback about your arousal state — when your heart rate increases in response to stress, excitement, or threat, that information should signal to consciousness that your state is changing, allowing you to respond before arousal escalates.
Respiratory interoception monitors breathing rate, depth, and effort. You can consciously feel when breathing becomes laboured or restricted, when you’re holding your breath, when breathing is shallow versus deep. This dimension links directly to emotional regulation because breathing patterns shift predictably with different emotional and arousal states. Impaired respiratory interoception means you might not notice when stress has shifted you to shallow chest breathing, missing an early signal of sympathetic activation that could have prompted regulatory intervention.
Gastric interoception detects hunger, fullness, nausea, and digestive activity. This is where the neurodivergent experience of “forgetting to eat” originates — not because you forgot that eating exists, but because your gastric interoceptive system didn’t transmit hunger signals with sufficient intensity or clarity to reach conscious awareness until blood sugar had already dropped critically. Similarly, difficulties with recognising fullness can lead to either undereating (no satiety signals received) or overeating (satiety signals arrive with significant delay).
Bladder and bowel interoception signals when elimination is needed. Impaired interoception in this dimension creates the experience of suddenly realising you desperately need the toilet with no gradual build-up of awareness. The bladder or bowel has been filling for hours, but the signals didn’t reach consciousness until they reached critical intensity. This isn’t poor planning or inattention — it’s late-arriving or absent interoceptive transmission until physiological urgency overrides the impaired bridge.
Thermoceptive interoception (distinct from external temperature sensation) monitors your core body temperature and thermal comfort. Neurodivergent individuals often report not noticing they’re too hot or cold until it’s extreme, then suddenly becoming aware of severe discomfort. This reflects impaired thermal interoception — your body is regulating temperature continuously, but the signals about that regulation aren’t reaching consciousness with typical clarity.
Proprioceptive-interoceptive integration tracks muscle tension, physical fatigue, and body position. While proprioception technically detects body position and movement, the feeling of muscle fatigue or tension bridges into interoception because it signals internal state rather than just position. Not noticing physical exhaustion building, then suddenly crashing, reflects impaired integration between proprioceptive and interoceptive systems.
Affective interoception processes the physiological signatures of emotions. Every emotional state generates characteristic patterns of internal activity — anxiety produces certain cardiovascular, respiratory, and muscular responses; sadness generates different patterns; excitement generates others still. Detecting these physiological patterns is how you identify what you’re feeling. Impaired affective interoception means emotions reach consciousness only after building to overwhelming intensity, because the subtle physiological shifts that signal emotional emergence aren’t being transmitted clearly to awareness.
Understanding these dimensions reveals why interoceptive impairment creates such pervasive challenges. You’re not just missing one type of signal — you’re operating with reduced or delayed access to multiple continuous information streams about your internal state that neurotypical individuals unconsciously rely on to modulate their behaviour.
Interoceptive accuracy, awareness, and sensibility
Researchers distinguish between three related but distinct aspects of interoceptive functioning, and understanding these distinctions matters for recognising what’s actually impaired and what interventions might help.
Interoceptive accuracy is objective performance on tasks measuring your ability to detect internal signals. The classic test involves counting your heartbeats over a period without taking your pulse, then comparing your count to actual heartbeat data. Accuracy is simply whether you can detect the signal correctly. Research consistently shows autistic individuals demonstrate lower interoceptive accuracy than non-autistic populations across multiple dimensions — cardiac, respiratory, and gastric. This is measurable physiological difference, not subjective experience.
Interoceptive sensibility is your subjective belief about how well you can detect internal signals — essentially, your confidence in your interoceptive abilities. Interestingly, interoceptive sensibility and accuracy don’t always align. You can believe you’re good at detecting hunger (high sensibility) while actually missing hunger signals frequently (low accuracy), or vice versa. Some neurodivergent individuals have high interoceptive sensibility — they believe they’re accurately reading their bodies — but objective testing shows their accuracy is low, meaning they’re confident in inaccurate perceptions. Others have low sensibility (they know they struggle to read their bodies) and this aligns with their low accuracy.
Interoceptive awareness is metacognitive — it’s the correspondence between accuracy and sensibility, or how well your beliefs about your interoceptive abilities match your actual performance. Good interoceptive awareness means you accurately understand your interoceptive capacities and limitations. If you know you don’t receive clear hunger signals, you can build compensatory structures. If you incorrectly believe you’re receiving accurate signals when you’re not, you’ll continue operating on faulty internal information without realising you need external supports.
This three-part framework explains why some neurodivergent individuals describe being “in tune with their bodies” while simultaneously experiencing frequent dysregulation from missed signals. They have reasonable interoceptive sensibility (confidence in their body awareness) but low interoceptive accuracy (actual signal detection), creating misalignment between perceived and actual internal state.
Building genuine interoceptive skill requires, naturally, working on all three interoceptive dimensions. Improving interoceptive accuracy means learning to detect subtler signals through deliberate attention and practice. Calibrating interoceptive sensibility means adjusting your confidence to match your actual abilities — neither overestimating nor catastrophising. And developing interoceptive awareness means accurately understanding which internal signals you receive clearly, which arrive with delay, and which rarely reach consciousness at all, so you can structure your life around your actual interoceptive architecture rather than the one you wish you had.
The interoception-emotion connection
Emotions are not purely mental phenomena — they are fundamentally embodied experiences manifesting as patterns of physiological activity that interoception detects and consciousness interprets as what we call “feelings”.
The James-Lange theory of emotion, proposed in the 1880s, suggested that emotional experience follows from physiological changes rather than causing them. You don’t run because you’re afraid — you feel afraid because you’re running and your body is in a fear state. Modern affective neuroscience has refined this understanding while validating the core insight: emotions emerge from the brain’s interpretation of interoceptive signals about your body’s current state.
Antonio Damasio’s somatic marker hypothesis extends this framework, proposing that decision-making and emotional processing depend on interoceptive feedback. When you encounter a situation, your body generates a physiological response (a “somatic marker”) — perhaps increased heart rate, changed breathing, gut sensations — and your brain uses these interoceptive signals to determine how to feel and what to do. Without clear interoceptive access to these markers, both emotional awareness and decision-making become impaired.
Lisa Feldman Barrett’s theory of constructed emotion goes further, arguing that emotions are not triggered reactions to situations but predictions your brain makes based on interpreting interoceptive signals in context. Your brain continuously monitors your internal state via interoception, compares that to learned patterns of how bodies feel in various situations, and constructs emotional experiences from that prediction. In this framework, impaired interoception fundamentally disrupts emotional processing because the brain lacks the clear internal data it needs to construct accurate emotional experiences.
For neurodivergent individuals with reduced interoceptive accuracy, this creates cascading challenges. You might experience physiological arousal — increased heart rate, muscle tension, shallow breathing — but without clear interoceptive signals, your conscious awareness doesn’t register “I’m anxious” until the arousal has built to overwhelming intensity. Or you might feel something’s wrong without being able to identify what, because the interoceptive signals are present but too weak or distorted for your brain to construct a clear emotional label.
Alexithymia — difficulty identifying and describing emotions — is significantly more common in autistic populations than non-autistic ones, and research links alexithymia directly to reduced interoceptive accuracy. If you can’t clearly detect the physiological patterns that define different emotional states, you can’t reliably identify what you’re feeling. The emotion exists — your body is responding — but consciousness doesn’t receive clear information about that response.
This explains why traditional emotion regulation strategies often fail for neurodivergent individuals. Approaches like cognitive reappraisal (reinterpreting situations to change emotions) or mindfulness (observing emotions without judgment) assume you can identify what you’re feeling clearly enough to work with it. If impaired interoception means you don’t know what you’re feeling until it’s overwhelming, these strategies arrive too late — you’re trying to regulate something that’s already reached crisis intensity.
Coherence-focused emotional work for neurodivergent individuals requires acknowledging interoceptive impairment and building approaches that compensate. This might mean using external signals instead of waiting for internal ones — regulating proactively at scheduled times rather than reactively when you notice dysregulation. It might mean developing a personalised map of which physical sensations you can detect and what they tend to signal. It might mean accepting that you won’t have neurotypical-level emotional granularity and building decision-making systems that don’t depend on subtle emotional awareness.
Building interoceptive skill in neurodivergent systems
You cannot force your interoceptive system to function like a neurotypical one, but you can improve your access to the signals your system does transmit and build compensatory structures for the signals that rarely, if at all, reach your conscious awareness.
Deliberate body scanning involves systematically directing attention to different body regions and internal systems, actively looking for sensations rather than waiting for them to announce themselves. This isn’t meditation or mindfulness for its own sake — it’s signal detection practice. Start with areas where you have relatively better interoception (many people detect muscle tension more easily than subtle hunger or emotional shifts) and gradually expand to dimensions where your accuracy is lower. The goal isn’t forcing signals into existence, but training your attention to detect weaker signals that are present but typically don’t reach consciousness spontaneously.
Heartbeat tracking is one of the most researched interoceptive training methods because cardiac awareness is measurable and improves with practice. Regularly checking whether you can detect your heartbeat without touching your pulse builds general interoceptive accuracy that often transfers to other dimensions. This isn’t about obsessing over your heart rate — it’s about strengthening the neural pathways that make internal signals conscious. Even neurodivergent individuals with initially low cardiac interoception can improve with consistent practice, though they may never reach neurotypical baseline accuracy.
Labelling and journaling creates external records that compensate for poor real-time interoceptive awareness. If you can’t reliably detect when you’re hungry, tired, or emotionally dysregulated in the moment, tracking patterns over time helps identify correlates you can detect. Perhaps you don’t feel hungry, but you notice difficulty concentrating always appears around 11am, three hours after breakfast. That concentration difficulty becomes your signal that you need food, even though gastric interoception never transmitted hunger directly. You’re building a personalised map of how your impaired interoceptive signals manifest as secondary effects you can detect.
Scheduled checking instead of signal-waiting acknowledges that some signals won’t arrive reliably, so you create external structure. Set timers to check: Am I hungry? Do I need the toilet? Am I tired? How’s my muscle tension? What’s my emotional state? These checks don’t depend on receiving clear internal signals — they prompt you to assess even when signals are absent or weak. Over time, combining scheduled checking with deliberate attention can strengthen your ability to detect signals, but even if accuracy never improves significantly, the scheduled structure prevents you from operating for hours without basic self-care because signals never reached consciousness.
Sensory integration and proprioceptive input can strengthen overall body awareness, which sometimes improves interoceptive accuracy indirectly. Activities providing strong proprioceptive feedback — heavy work, resistance exercises, deep pressure — seem to enhance general sensory processing in ways that can make interoceptive signals more accessible. This isn’t guaranteed, and the mechanism isn’t fully understood, but many neurodivergent individuals report that regular proprioceptive input improves their ability to detect internal states.
Accepting limitations and compensating might be the most important skill. If your gastric interoception is severely impaired, waiting to eat until you feel hungry will leave you chronically undernourished and dysregulated. Eating on schedule regardless of hunger signals isn’t admitting defeat — it’s acknowledging your system’s actual architecture and building structures that work with it. If you don’t detect emotional states until they’re overwhelming, building your life to minimise situations requiring subtle emotional awareness isn’t avoidance — it’s coherence.
The goal is NOT neurotypical-level interoception. The goal is accurately understanding which signals your system transmits clearly, which arrive with delay, and which rarely reach consciousness, then structuring your life around that reality rather than the interoceptive capacity you wish you had. This is sovereignty as self-ownership claimed — knowing your system and operating accordingly — not resignation.
Key figures and publications in interoception
A.D. Craig and the neuroscience of interoception
A.D. (Bud) Craig’s neuroanatomical research mapped the brain pathways processing interoceptive information, fundamentally advancing scientific understanding of how internal signals reach consciousness. His work identified the insular cortex, particularly the anterior insula, as the primary cortical region integrating interoceptive signals with emotional and cognitive processing.
Craig’s 2002 paper How Do You Feel? Interoception: The Sense of the Physiological Condition of the Body in Nature Reviews Neuroscience provided a comprehensive framework for understanding interoception as a distinct sensory system with dedicated neural pathways. His research demonstrated that the lamina I spinothalamocortical system carries information about the physiological condition of all body tissues to the brain, creating a neural representation of your internal state.
His work established that the insula contains a map of your body’s internal condition, analogous to how other brain regions map external space or body position. This “interoceptive cortex” provides the neural substrate for conscious awareness of internal states and connects directly to regions processing emotion and self-awareness. Craig’s anatomical findings explained why damage to the insula impairs both interoceptive accuracy and emotional processing — these functions share neural infrastructure.
For neurodivergent individuals, Craig’s work provides biological validation that interoceptive differences are measurable neural phenomena, not psychological failings. The pathways he mapped can function with different characteristics in different individuals, explaining why some people have clear access to internal signals while others don’t receive them until extreme intensity.
Sarah Garfinkel and interoceptive processing in autism
Sarah Garfinkel’s research at the University of Sussex directly investigates how autistic individuals process interoceptive information, providing empirical evidence for experiences neurodivergent people have long reported but which were previously dismissed as anecdotal.
Her 2015 study Knowing Your Own Heart: Distinguishing Interoceptive Accuracy from Interoceptive Awareness established the crucial distinction between interoceptive accuracy (objective performance), sensibility (subjective confidence), and awareness (metacognitive alignment). This framework allows precise identification of where interoceptive processing breaks down — whether you can’t detect signals, don’t realise you can’t detect them, or correctly understand your limitations.
Garfinkel’s work with autistic populations demonstrates consistent patterns: autistic individuals show reduced interoceptive accuracy across multiple dimensions (cardiac, respiratory, affective) compared to non-autistic controls, and this reduced accuracy correlates with alexithymia and emotional processing difficulties. Importantly, her research shows these aren’t secondary effects of anxiety or other co-occurring conditions — they persist even when controlling for mental health variables.
Her later work explores how interoceptive training might improve accuracy and whether such improvements transfer to emotional awareness and regulation. While results show some individuals can improve interoceptive performance with practice, the gains are often modest and don’t necessarily generalise across different interoceptive dimensions. This suggests fundamental differences in interoceptive processing that training can partially compensate for but not eliminate.
For neurodivergent individuals, Garfinkel’s research provides scientific validation of lived experience — the “I forgot to eat” phenomenon and emotional awareness difficulties are measurable consequences of atypical interoceptive processing, not character flaws requiring better self-discipline.
Hugo Critchley’s research on interoception and anxiety
Hugo Critchley’s work at the University of Sussex investigates how interoceptive processing relates to anxiety, with findings particularly relevant for neurodivergent populations who experience high rates of anxiety disorders.
His research demonstrates that anxiety involves altered interoceptive processing — specifically, increased attention to interoceptive signals combined with distorted interpretation of those signals. Anxious individuals often show heightened cardiac interoceptive awareness but misinterpret normal heartbeat variations as dangerous, creating feedback loops where attention to internal sensations generates more anxiety, which generates stronger internal sensations, perpetuating the cycle.
Critchley’s work with autistic populations shows a paradoxical pattern: reduced interoceptive accuracy overall, but sometimes heightened attention to internal sensations in specific domains. This creates situations where autistic individuals might not accurately detect hunger or fatigue but become hyperaware of cardiac activity during stress, amplifying anxiety without providing useful regulatory information.
His research on the insula’s role in both interoception and anxiety helps explain why these systems interact. The anterior insula integrates interoceptive signals with emotional processing and salience detection — it determines which internal signals are important enough to reach consciousness and how to interpret them. Atypical insula function in autism affects both baseline interoceptive processing and the anxiety responses that emerge from misinterpreting internal signals.
For neurodivergent individuals experiencing anxiety, Critchley’s work suggests that interventions need to address interoceptive processing specifically, not just cognitive anxiety patterns. If your anxiety stems partly from misinterpreted interoceptive signals, cognitive techniques alone won’t resolve the underlying processing difference generating the distorted signals.
Kelly Mahler’s practical interoceptive curriculum
Kelly Mahler developed practical interoceptive training specifically for autistic individuals, translating research into accessible interventions that can be implemented in educational and therapeutic contexts.
Her book The Interoception Curriculum: A Step-by-Step Guide to Developing Mindful Self-Regulation provides structured activities for building interoceptive awareness across different dimensions and ages. Unlike generic mindfulness programs, Mahler’s approach explicitly acknowledges that autistic individuals process interoceptive information differently and need tailored approaches that work with their specific neurological architecture.
Mahler emphasises that interoceptive training isn’t about forcing autistic people to achieve neurotypical-level accuracy. It’s about improving whatever accuracy is possible while building compensatory strategies for signals that may never reach consciousness clearly. Her curriculum includes body scanning exercises, movement activities that provide strong proprioceptive input to enhance overall body awareness, and structured reflection helping individuals identify which signals they can detect and what patterns those signals follow.
Importantly, Mahler’s work validates that some individuals will make substantial interoceptive gains while others improve only marginally, and both outcomes are acceptable. The goal is operating with accurate understanding of your interoceptive capacities — whether high or low — not achieving some external standard. Her practical focus on building self-knowledge rather than fixing deficits aligns with coherence-first approaches that prioritise understanding your actual system over forcing it to approximate a different one.
For neurodivergent individuals and those supporting them, Mahler’s curriculum provides concrete tools for addressing interoceptive challenges without pathologising or demanding conformity to neurotypical processing patterns.

Neuroception: While neuroception operates entirely beneath conscious awareness, interoception provides the bridge that makes some neuroceptive signals accessible to consciousness. Neuroception continuously scans for threat and adjusts autonomic state, but you only consciously register those shifts if interoception transmits the resulting physiological changes — increased heart rate, changed breathing, muscle tension — to awareness. Impaired interoception means neuroceptive threat responses build beneath consciousness, and you only detect dysregulation when it reaches critical intensity, explaining why meltdowns feel like they “come from nowhere.”
The nervous system: Interoception is one component of the nervous system’s subconscious signalling stack, specifically the bridge between autonomous physiological regulation and conscious awareness. Your nervous system manages countless regulatory functions continuously — cardiovascular activity, digestion, temperature regulation, hormonal balance — and interoception selectively makes some of that information accessible to consciousness. Understanding interoception as a neural system rather than a psychological skill reframes impairment from character flaw to architectural difference requiring different approaches to access internal information.
Executive function: Executive function depends heavily on interoceptive information, and impaired interoception compounds executive challenges. Planning requires assessing your current state and predicting future needs — if you can’t detect fatigue, hunger, or emotional state accurately, your planning, your executive functioning, operates on incomplete information. Working memory degrades when you’re dysregulated, but without interoceptive signals warning you that dysregulation is building, you can’t intervene before working memory collapses. Task initiation becomes harder when you can’t detect whether you have the physical and emotional resources to begin, creating executive paralysis that stems from interoceptive uncertainty rather than pure executive dysfunction.
Alexithymia: Alexithymia — difficulty identifying and describing emotions — directly correlates with reduced interoceptive accuracy because emotions manifest as patterns of physiological activity that interoception detects. If you can’t clearly detect the tight chest of anxiety, the heavy limbs of sadness, or the racing heart of excitement, you can’t reliably identify what you’re feeling. Research shows alexithymia is significantly more common in autistic populations and links directly to interoceptive impairment, validating that emotional awareness difficulties stem from atypical neural processing of bodily signals rather than emotional immaturity or psychological defence.
Sensory processing: Sensory processing typically refers to exteroceptive senses (sight, sound, touch, taste, smell), but interoception processes internal sensory information through parallel neural pathways. Just as exteroceptive processing can be hypersensitive or hyposensitive in neurodivergent individuals, interoceptive processing shows similar variability — some dimensions hyperaware, others barely accessible, often fluctuating based on overall arousal and regulation state. Understanding both exteroceptive and interoceptive processing as part of broader sensory processing architecture explains why neurodivergent individuals often experience challenges across multiple sensory domains simultaneously.
