Sleep that fits the life you actually have

There is a popular script for what good sleep is supposed to feel like: eight hours, slept straight through, waking early and refreshed. It reads well, but like most scripts it does not match everyone's story, because sleep is shaped by biology, life stage, hormones, and circumstance. The gap between the script and the lived experience is often what makes the experience so concerning, and the work, where there is work to do, is closer to understanding the fit than to forcing it.

The script and the life

There is a script for what good sleep is supposed to look like. Eight hours. Beginning around ten. In a cool dark room. Ending naturally by seven. I have spent enough time in conversations about sleep to know that this script describes very few of the people who actually live with sleep difficulty. And the gap between the script and the lived experience is itself often part of what makes the experience so concerning.

I want to start with something I find clinically useful. Sleep is not a standard applied evenly across humans. It is a system shaped by biology, by life stage, by hormones, and by circumstance. None of those four things are within a person's control in any simple way. So the question of what your sleep is "supposed" to look like is, in the most honest sense, a question with no single answer.

This matters because so much of the suffering around sleep is the suffering of feeling abnormal. A person sleeps from midnight to eight and concludes that they are sleeping wrong. Another person needs nine and a half hours and concludes that they are excessive. A third person fragments through the second half of every night and concludes that they have insomnia, when in fact they are perimenopausal and the architecture of their sleep is doing exactly what hormonal change predicts. The script imposes a standard, and the standard then imposes the diagnosis of failure on people whose sleep is, in fact, doing what their system is set to do.

Chronotype as a biological trait

The most basic individual difference is chronotype, the body's natural inclination toward earlier or later sleep. Some people are biologically inclined toward earlier sleep and earlier waking. Others are inclined toward later. This is not laziness or willpower or moral character. It is heritable, distributed across the population, and varies with age and sex (Roenneberg et al., 2007). Adolescents shift later, sometimes dramatically. Older adults shift earlier. The range of normal is wider than the script suggests.

A person whose biology wants to sleep from midnight to eight is not, in any meaningful sense, sleeping poorly. They are sleeping at the time their system is set for. When there is a problem, it is usually a mismatch between this timing and the demands of work, school, or family life. The biology is not broken. The fit is.

The implication is significant for how a person thinks about their own sleep. If your chronotype is later than the standard, you are not failing to enforce a normal sleep schedule. You are running on a different one, and the question becomes whether you can build a life that accommodates it, rather than whether you can force yourself into one that does not.

Life stage rearranges the system

Life stage rearranges things further, and the rearrangements are not failures. They are predictable shifts in the architecture and timing of sleep across the lifespan.

The perimenopausal transition, which can begin in the early 40s and extend into the 50s, disrupts sleep in a high proportion of women, primarily through vasomotor symptoms, the hot flushes and night sweats that come with hormonal change, and through broader hormonal fluctuation (Baker et al., 2018; Haufe et al., 2022). Sleep becomes lighter. More fragmented. Often punctuated by night-time waking that does not have a clear thought-content cause. It is hormonal, not cognitive, and I think it is important to name this directly because I see many women whose broken sleep has been framed to them as a stress issue when the underlying driver is hormonal. Stress-only framings tend to miss what is actually shifting.

Older adults sleep less deeply, wake more easily, and tend to fall asleep and wake earlier. The architecture changes. Time in deep slow-wave sleep reduces. The circadian rhythm advances. None of this is failure. It is the shape of an older system. The expectation of returning to the sleep patterns of a thirty-year-old is, in my clinical experience, one of the most common sources of distress in older adults' sleep. And one of the most workable, because what often changes is the expectation, not the sleep.

Neurodivergent sleep deserves its own note

Sleep patterns in ADHD and autism deserve their own note here, because the standard script reads them as failures particularly often.

People with ADHD show a strong tendency toward evening chronotype and delayed sleep phase, and the evidence across cohort studies and systematic reviews is consistent (Coogan & McGowan, 2017). The neurological basis is increasingly understood to involve the circadian system itself, not just patterns of behaviour. Recent evidence suggests that roughly 3 in 4 children and adults with ADHD show a delayed sleep/wake cycle, much more common than in the general population.

Recent work on cognitive behavioural therapy for insomnia in neurodivergent populations is promising but still emerging, with most studies small and protocols still being refined (Cullen et al., 2025). The targets are usually circadian: morning light exposure, holding a consistent wake time even on poor-sleep nights, and where appropriate, medical guidance on the timing of medication or supplementation.

Autism-specific sleep patterns are less well-characterised in the literature, though sensory processing differences, anxiety, and rigidity around routine often shape the picture clinically. What both have in common, with the standard script, is the routine experience of being told they are sleeping wrong, when in fact they are sleeping the way their nervous system is set up to sleep, and the work is in the fit, not in the forcing.

Sleep is not one thing applied to many lives. It is shaped by the life it is happening inside.

Sitting with the fit

I find I want to leave this where it is, rather than tie it neatly. Sleep that does not match the standard script is not, in itself, a sleep problem. The work, where there is work to do, is closer to understanding the fit than to forcing alignment with a script that was not designed for this particular system. The question is rarely "how do I make my sleep look normal." The question, when I sit with someone honestly, is usually "what does my system actually need, and what can I work with."

The standard script is a generalisation, and it was built for a hypothetical average sleeper who does not actually exist in pure form. Your biology is more specific than that. Your life stage is more specific than that. The hormonal and neurological architecture you are working with is more specific than that. The work of sleeping well, when it is work, is rarely the work of conforming. It is more often the work of understanding what your particular system needs, and arranging the life you can actually arrange around that. That second question is harder, and slower, and I think that is part of why it gets avoided. But it is the more useful one, because it starts from what is actually there rather than from what was supposed to be there, and what is actually there is the only place from which any real change can begin.
