The Sense They Were Never Taught: Interoception and What Residential Care Can Do About It

Interoception is the body's system for sensing its own internal state — the nervous system's capacity to register and transmit information about what is happening inside: heart rate, hunger, fullness, temperature, pain, breathlessness, the heaviness of grief before it becomes articulable as an emotion. It is often described as the eighth sense, alongside the seven that describe our engagement with the external world. Without it, we cannot reliably answer the question that is at the foundation of emotional life: how do I feel? Not in the cognitive sense — not "what should I feel in this situation?" — but the prior, physical question: what is actually happening in my body right now? For most people, interoception operates below conscious awareness most of the time, translating internal signals into the emotional and physical landscape of daily experience: the recognition that it is time to eat, that you are more stressed than you realised, that something is wrong before you can name what it is. For children who have experienced developmental trauma, this system is often profoundly disrupted — and the disruption is one of the most practically significant, and least discussed, features of the experience of young people in residential care.

The research on interoception and early adverse experience is relatively recent but consistent. Studies using functional neuroimaging have shown that the interoceptive pathway — which runs from the body through the insular cortex, the part of the brain most associated with the subjective sense of being in a body — is specifically affected by early experiences of neglect and maltreatment. Children who grow up in environments where their physical and emotional signals were consistently unresponded to, or where the body's distress signals did not reliably produce relief, do not develop the same capacity to notice, interpret, and act on internal signals as children who grew up with attuned, responsive caregivers. This makes a certain developmental sense: if no one taught you to read your internal weather, or if reading it proved unreliable or dangerous, the nervous system learns to tune it out. The body sends its signals; the signals go largely unnoticed or are misread; the child develops a relationship to their own internal experience that is at best imprecise and at worst completely disconnected. Bessel van der Kolk's framework makes the same argument from a different angle: trauma disrupts the body's capacity to self-regulate, and self-regulation depends on the ability to notice what needs regulating in the first place. A young person who cannot accurately sense what is happening in their body cannot self-regulate, because they are missing the internal feedback that regulation requires.

In practice, impaired interoception presents in residential care in ways that are familiar but often not conceptualised in these terms. The young person who does not notice they are hungry until they are in a rage state — and who has never connected the rage to the hunger — is experiencing impaired interoceptive signalling: the system that should have generated a gentle "I need food" has instead produced a physiological state that was not interpreted in time. The young person who consistently says they are fine when they are clearly not — not as a performance of self-sufficiency, not as a defence, but because they genuinely cannot access accurate information about how they feel — is disconnected from their own interoceptive signal. The young person who escalates to physical complaints (headaches, stomach aches, vague physical symptoms that resist medical explanation) in situations of emotional stress is likely translating an emotional state they cannot name into a physical one they can. The one who will eat until they are ill, without appearing to notice that they are full, has lost or never developed the satiety signal that would normally interrupt intake. These are not character traits or choices. They are the predictable outcome of a developmental history in which the interoceptive system was not cultivated by a responsive adult environment.

There is a clinical dimension here that residential homes need to understand. Alexithymia — the difficulty identifying and describing one's own emotional states — has a significant overlap with impaired interoception, and it is substantially more common among people who have experienced childhood adversity than in the general population. The evidence suggests that alexithymia is, at least in part, an interoceptive deficit: the difficulty naming feelings is downstream of the difficulty sensing them. This matters because much of the therapeutic work offered to young people in residential care — the keywork conversations, the emotional literacy programmes, the approaches that ask young people to identify their thoughts and feelings — presuppose an interoceptive capacity that many of these young people do not have. A young person who is asked "what are you feeling right now?" and genuinely cannot answer is not being resistant. They are being asked to read from a book they were never taught to open. Residential homes that have invested in emotional literacy programmes and found that some young people make little progress despite evident engagement may be experiencing the downstream effects of impaired interoception: the young person can learn the vocabulary of emotional states, but without an internal signal to attach it to, the words remain abstract.

The good news is that interoception appears to be a trainable capacity. Research from educational settings, somatic therapy, and body-based movement practices consistently shows that deliberate, attentive practice at noticing internal body signals — not as a clinical exercise but as an integrated feature of daily activity — develops the capacity over time. What this looks like in residential care is not a programme, though programmes can be useful. It is a way of attending to the moment, introduced gently and without pressure, that invites young people to notice what is happening in their bodies before the signal becomes a crisis. The residential worker who, in the middle of making dinner, says "I just noticed I'm getting a bit tense — I think it's because I'm hungry" is modelling the interoceptive check-in: the moment of turning attention inward, noticing, and interpreting. The keyworker who, when a young person is clearly building toward something, asks "where are you feeling that in your body?" rather than "what are you thinking about?" is working at the right level for a young person whose feeling states are embodied before they are cognitive. The home that builds consistent, low-pressure attention to body signals into the rhythm of daily life — through mealtimes that involve conversations about food and hunger and taste, through physical activity that invites awareness of what the body can do, through the simple practice of asking people how they slept and meaning it — is doing something measurably different from the home that treats the body as a practical concern rather than an experiential one.

The therapeutic applications of interoceptive work are growing. Occupational therapists who work with children with sensory processing differences have long understood the relationship between sensory integration and interoception, and some trauma-informed OT practice is explicitly addressing interoceptive development in looked-after children. The growing interest in yoga, breathwork, and body-based practices in trauma recovery settings is partly explicable through the interoceptive lens: these practices work, in part, by directing deliberate attention to internal states and developing the capacity to notice and tolerate them without being overwhelmed. Sarah Garfinkel's research at University College London on the neural basis of interoception and its relationship to anxiety and emotion has been influential in bringing the concept into mainstream clinical conversation, and work on heartbeat-focused exercises as a route into interoceptive awareness has practical implications for anyone thinking about what these interventions might look like in daily life. Residential homes that have introduced yoga or mindful movement and found that some young people engage with unexpected enthusiasm may be witnessing interoceptive development in action: the young person who says they find it "calming" is, in interoceptive terms, developing the capacity to sense and interpret what calm actually feels like from the inside.

What would it mean for a residential home to take interoception seriously as a practical concept? It would mean staff who understand what it is and who recognise its presentations without pathologising them — who understand that a young person who cannot say how they feel is not withholding, but working from an incomplete map. It would mean a therapeutic model that includes body-based awareness as an ordinary feature of how the home pays attention to young people. It would mean keyworking that includes, alongside the conversations about history and feeling and meaning, a gentle and consistent practice of helping young people notice what is happening in their bodies. It would mean health appointments that explicitly attend to physical sensations in ways that support rather than demand interoceptive accuracy — because the young person who cannot reliably report pain levels or describe physical symptoms is not being uncooperative; they are operating from a body map with significant blank spaces. And it would mean a culture of curiosity about the body that mirrors the culture of curiosity about the mind that the best residential care has always tried to build. Young people who leave care with a reasonably developed capacity to notice and interpret their own internal states have been given something with lifelong implications. They are more able to regulate their own emotions, to identify when they need support, to recognise stress before it becomes crisis, to know when they are unwell, to make choices about their bodies that are based on what they actually feel. This is not a luxury outcome. It is a developmental foundation — and homes that work at the level of the body as assiduously as they work at the level of the mind are closing a gap that, without deliberate attention, typically remains open across an entire life.
