Still Waking: Sleep, Trauma, and What Residential Homes Must Understand About the Night

At some point in most residential homes, on most nights, a young person is awake when they should be asleep. The surface presentation of this varies: they are in the corridor again, or their light is on, or they are playing something on their phone at two in the morning, or they have come downstairs for the third time asking for a glass of water. The residential worker on sleep-in responds, as they are trained to, by redirecting toward bed — calmly, without escalation, with the kind of patient firmness that the role requires. What this response, delivered thousands of times across thousands of homes on thousands of nights, frequently does not include is any genuine reckoning with what is actually happening for a young person who cannot sleep. The inability to sleep, in a child whose early life has been characterised by fear, loss, and unpredictability, is not a behavioural issue to be managed. It is a physiological state rooted in a body that has learned, through experience, that night is not safe — and that learning does not disappear because a placement has improved their circumstances. Sleep difficulties in residential care are close to universal among the young people placed there. They are also among the least systematically addressed aspects of the work.

The neurobiological account of why traumatised children cannot sleep is by now well established, even if it has yet to reshape practice in the way the evidence warrants. Children who have grown up in environments characterised by unpredictability, threat, or chronic stress develop a nervous system calibrated toward vigilance. The hypothalamic-pituitary-adrenal axis — the body's primary stress-response system — is activated repeatedly during development, and in conditions of chronic early adversity its regulation is altered: cortisol levels that should taper through the evening and reach their nadir in the small hours remain elevated, keeping the body in a state of physiological readiness that is fundamentally incompatible with restful sleep. The amygdala — the brain's threat-detection structure — in a traumatised child is sensitised to cues that the environment may not be safe, and darkness, aloneness, and stillness, which are the ordinary conditions of sleep, are also the conditions in which danger was historically most acute. For a young person who spent years not knowing what the night would bring — who has memories, explicit or somatic, of the night as a time of harm — the act of falling asleep requires a surrender of vigilance that the body's learned architecture resists. This is not a choice. It is not defiance, manipulativeness, or an attempt to extend screen time. It is the logical expression of a nervous system doing precisely what it was conditioned to do: staying alert when the lights go out.

The consequences extend well beyond the hours of darkness, and here lies the most commonly missed connection in residential practice. Sleep deprivation in adolescents produces a profile of effects — impaired emotional regulation, heightened reactivity, reduced impulse control, diminished concentration, increased risk-taking, flattened mood — that is strikingly similar to the profile that residential staff are already managing as the presenting needs of the young people in their care. When a young person arrives at school unable to focus, or escalates to what appears to be disproportionate distress mid-afternoon, or makes a decision in the evening that staff struggle to understand, the sleep they had the previous night is almost never part of the clinical formulation. It is invisible in care plans, absent from risk assessments, and rarely the subject of conversation in multi-disciplinary meetings. Yet the research is unambiguous: children who sleep fewer than the recommended hours for their developmental stage — and traumatised young people in residential care are, as a group, significantly sleep-deprived — are more emotionally volatile, more behaviourally dysregulated, and less able to access the higher-order cognitive functions that therapeutic work depends upon. A residential home that invests significantly in therapeutic approaches and skilled relational practice, while leaving chronic sleep deprivation unaddressed, is building on a foundation that the evidence suggests will consistently undermine the results it is trying to achieve.

The typical residential home's approach to sleep is structured around routines — bedtimes, expectations about staying in rooms, policies around screens after a certain hour — which are not wrong in themselves, but which often reflect a model of sleep as something that happens when you follow the rules rather than something that happens when the body and nervous system are ready. A young person who is given a bedtime of ten o'clock and a firm expectation that they remain in their room does not thereby sleep at ten o'clock. They lie in the dark, physiologically aroused, without the regulating presence of another human being, and the darkness and aloneness that their nervous system reads as threat become the conditions in which sleep is supposed to occur. Trauma-informed approaches to nighttime start from a different premise: that the body needs support to transition from arousal to rest, and that this support is environmental, relational, and sensory before it is rule-based. Wind-down routines that reduce stimulation in the hour before bed — low lighting, quieter shared spaces, predictable sequence — help the nervous system begin the transition. Sensory resources can be meaningful: weighted blankets, which provide proprioceptive input that has been shown to reduce cortisol and support the parasympathetic response, have a growing evidence base for use with trauma-affected children; white noise or low music in sleeping rooms can provide auditory consistency that reduces the alerting effect of unexpected sounds in the night. Nightlights are not a concession to immaturity but a recognition that darkness is a genuine trigger for young people whose experience has made it so.

The relational dimension of nighttime is the one that the standard sleep-in model most readily undervalues. For a child whose early experience associated night with danger and isolation, the single most regulating factor in a residential home after dark is the known, trusted presence of another person. The sleep-in worker is that presence — in the building, reachable — but for a young person who needs a co-regulatory encounter in order to downshift from vigilance to rest, "available if needed" is not the same as "present." Brief, low-key contact in the settling period — not a formal check-in or a structured conversation, but the kind of natural passing contact that happens in a household — can do more to support a young person's transition to sleep than any rule about screens or any policy about bedtimes. A worker who sits outside a young person's room for ten minutes after lights-out, saying almost nothing, present in voice and body, is providing something physiologically real: the co-regulation that their nervous system cannot yet achieve independently. This is not a reward for staying awake. It is an active ingredient in the process of sleep — one that most children receive from parents without either party understanding why it helps, and that residential homes could provide deliberately and with considerably more effect than the current default approach.

Good practice in this area looks less like a sleep policy and more like a sleep culture: a team-wide understanding that the nighttime environment is a therapeutic environment, that what happens after lights-out is not a period of reduced care but a continuation of it, and that a young person who cannot sleep is not a management problem but a person whose nervous system requires support. It means keyworkers who know each young person's particular relationship to night: what their history with darkness is, whether they have recurring nightmares and what themes those nightmares carry, whether they have sensory needs that a standard bedroom does not meet, whether they have ever named what night is like for them and whether someone has ever listened to the answer. It means care plans that include, as standard, something about sleep — not just a bedtime, but an account of what the nights are like, what has helped in the past, and what the home is actively doing to support rest. It means registered managers who make the connection between sleep and the daytime behaviours they are managing, and who resist the temptation to address the surface presentation while leaving the underlying deprivation untouched. A residential home that takes sleep seriously is a home that has understood something about the continuity between night and day in the life of a traumatised child: that the hours they spend in their room are not a pause in the care. They are part of it, and they deserve the same quality of thoughtful, evidence-informed attention that the rest of the working day receives.
