Foucault Knew: When Self-Care Becomes Self-Surveillance
Self-care and self-surveillance are structurally different — and modern wellness culture keeps conflating them. There’s a now well-documented self-optimization phenomenon called orthosomnia (sleep anxiety caused by obsessing over sleep tracker scores). People lying awake, anxious about their sleep data, losing sleep in the process of trying to optimize it. The tracker becomes the source of the problem it’s supposed to solve.
It’s almost too perfect as a metaphor. But it’s not a metaphor. It’s just what happens when self-surveillance masquerades as self-care.
Michel Foucault spent the last years of his life writing about exactly this, or at least the structural conditions that make it possible. The History of Sexuality, Volume III: The Care of the Self (1984), published the year he died, is the least-read part of the Foucault canon. It’s also, for the current moment, the most useful.
The philosopher famous for analyzing how institutions exercise power over bodies spent his final work describing how ancient people cultivated care of the self as a practice of freedom. Not optimization. Not surveillance. Freedom. And the distinction matters more now than it did when he wrote it.
The Quick Version
In The Care of the Self, Foucault argued that ancient practices of attending to oneself were relational, open-ended, and transformative — fundamentally different from what he called “technologies of domination.” Modern self-optimization collapses this distinction: it packages self-surveillance as self-care, turning the most intimate practices of personal growth into performance metrics and compliance with internalized norms. The result isn’t flourishing. It’s the achievement society’s last outpost — you’re the final boss, and also the one grading yourself.
The Revolt That’s Already Happening
The Global Wellness Summit’s 2026 Future of Wellness report named the “Over-Optimization Backlash” as the defining trend of the year, describing a consumer revolt against performance-obsessed wellness culture. Sleep scores, HRV readings, biological age calculations, step counts, fasting windows, cold plunge protocols. Never before has health been so measurable. Never before has it felt so psychologically corrosive.
The backlash isn’t irrational. It’s a response to something real: the felt sense that the project of optimizing yourself has become indistinguishable from surveilling yourself. That the pursuit of well-being has become another arena of performance, complete with data, rankings, and failure modes.
Foucault, who never owned a Fitbit, could have predicted this.
What Foucault Was Actually Doing in 1984
The Care of the Self is a strange, underread book. Most people know Foucault through Discipline and Punish: the panopticon, the surveilling gaze, power inscribed on bodies through institutions. That Foucault is the critical theorist of control.
The late Foucault is something different. In the final volumes of his History of Sexuality, he turned from analyzing how power operates on subjects to asking how subjects might practice freedom on themselves, not in spite of the power structures that shape them, but through thoughtful, intentional cultivation of the self.
He went back to the ancient Greeks and Romans. Specifically, to their concept of epimeleia heautou — care of the self. And he found something he wasn’t expecting: a rich tradition of self-attention that bore almost no resemblance to modern self-optimization.
What Is “Care of the Self”?
Care of the self (epimeleia heautou in Greek) was the ancient practice of attending to one’s own soul, habits, and character through philosophical reflection, dialogue with others, and sustained ethical engagement. For Foucault, these ancient “technologies of the self” were practices of freedom — ways of shaping oneself while remaining responsive to others and open to transformation. They were fundamentally different from the internalized norms and performance demands of modern self-improvement, which Foucault categorized as “technologies of domination.”
The ancient version had several features that the modern one lacks.
It was relational. You didn’t care for yourself alone. You did it with a teacher, a friend, a philosophical community. The Stoics — Marcus Aurelius exchanging letters with Fronto, Seneca writing to Lucilius — were practicing care of the self as something explicitly shared. The point wasn’t to optimize a metric in private. It was to refine how you thought and lived in relationship with others.
It was transformative rather than corrective. Ancient care of the self wasn’t about fixing deficiencies or achieving targets. It was about becoming — developing a more deliberate, examined relationship with your own desires, fears, and judgments. The goal wasn’t a score. It was character.
It was ethically grounded. The practices were connected to explicit questions about how to live well — what was worth wanting, what constituted a good life. Self-examination was in service of ethics, not performance.
The contrast with modern self-optimization isn’t subtle. Modern self-optimization is individual, data-driven, target-oriented, and largely uninterested in ethics. It asks: is your sleep efficiency above 85%? Is your HRV trending upward? Are you hitting your protein targets? These are questions with numerical answers. They’re not questions about how to live.
Technologies of the Self vs. Technologies of Domination
This is where Foucault’s framework becomes pointed.
Foucault distinguished between two kinds of self-directed practices. Technologies of the self allow individuals to “effect by their own means or with the help of others a certain number of operations on their own bodies and souls, thoughts, conduct, and way of being.” These are genuinely self-directed. They’re about cultivation, transformation, examining how you want to live.
Technologies of domination, by contrast, are practices that appear self-directed but actually operate in service of normalizing power — bringing the self into alignment with externally imposed standards, policing the self on behalf of larger control mechanisms.
Foucault’s point — and a 2026 analysis on Medium made this explicit — is that modern self-optimization largely belongs to the second category. The biohacker tracking every sleep cycle, stressing about suboptimal HRV, overhauling their diet based on continuous glucose monitor readings: they feel like they’re practicing freedom. They feel like they’re taking ownership of their health. What they’re actually doing is policing themselves on behalf of a productivity culture that benefits from having maximally efficient, maximally self-managing subjects.
It’s surveillance that looks like self-care. The panopticon went internal.
Byung-Chul Han made an adjacent argument about the achievement society — that modern subjects have become simultaneously master and slave, driving themselves harder than any external boss ever could. Han’s lens is political economy. Foucault’s is the history of subjectivity. They’re describing the same room from different windows.
Why the Wellness Industry Got This Backwards
The wellness industry’s error isn’t selling bad products. Some wearables genuinely help some people. Sleep data can be genuinely useful when it helps someone notice a pattern and make a single behavioral change. The error is in the ideology that surrounds the products: the idea that more measurement leads to more care, that quantification is the path to flourishing.
This ideology has a history, and Foucault’s work illuminates it. The idea that the body is something to be known, managed, and optimized — rather than inhabited, enjoyed, attended to — is a modern development. It belongs to the same epistemic shift Foucault traced in Discipline and Punish: the extension of knowledge-production practices from institutions (prisons, clinics, schools) into the most intimate domains of personal life.
When that shift goes internal, something gets inverted. The person who now sleeps with a tracker on their wrist isn’t just using a tool. They’ve accepted a position as both the object of surveillance and its administrator. Every morning brings a performance review. Every afternoon offers a chance to correct deficiencies. The day off from tracking feels irresponsible. The bad sleep score feels like failure.
Josef Pieper wrote about a related problem from a different angle — that genuine rest had been colonized by total work culture, converted into something that needed to justify itself through productivity. Pieper’s argument was about values. Foucault’s is structural: the colonization of rest isn’t just a values problem. It’s a feature of how modern power operates through self-managing subjects who’ve internalized the surveillance function.
The Orthosomnia Problem, Structurally
Return to orthosomnia for a moment. The researchers who coined the term — from Northwestern University and Rush University Medical Center found patients arriving at sleep clinics whose insomnia was caused by anxiety about their sleep tracker scores. They trusted the device’s reading of their sleep over their own felt sense of being rested.
This is precisely what Foucault would have predicted. When you’ve installed a surveillance apparatus, you gradually learn to defer to its outputs over your own experience. The number becomes more real than the feeling. The metric displaces the sensation. You stop asking “how do I feel?” and start asking “what does the data say?”
That’s not care of the self. That’s the self managed by proxy — with you as both the proxy and the managed object.
Self-compassion research keeps running into the same problem from the clinical side: the people who struggle most to be kind to themselves are often the ones most committed to self-improvement regimes. Because the improvement project carries an implicit indictment — if I’m still working on optimizing X, I haven’t gotten X right yet. Perpetual improvement is structurally incompatible with self-acceptance. The project requires a failure state to continue.
What Self-Care Actually Looks Like (vs. Self-Surveillance)
Foucault doesn’t leave us with only critique. His late work offers an alternative practice — not a program, but a reorientation.
Genuine care of the self has some distinguishing features:
It’s attentive to felt experience, not just data. The ancient practices weren’t about tracking metrics. They were about developing a more sensitive, more honest relationship with your own inner life — your desires, your fears, what you actually found good. The question was qualitative: what kind of person am I becoming? Not quantitative: am I trending in the right direction?
It’s relational. The Stoics wrote letters to each other about their struggles. They shared practices. The point was never to optimize privately. If your wellness practice is entirely solitary and data-driven, something is missing from the ancient model.
It’s explicitly ethical. Care of the self, for Foucault’s Greeks and Romans, was inextricably connected to questions about how to live well with others — what constituted virtue, what obligations you had, what kind of life was worth living. Self-attention divorced from ethics is just narcissism with better data.
It has natural endpoints. A practice of care has a shape — it begins, deepens, and completes. Self-optimization has no endpoint. It’s structurally infinite, because there’s always a higher score to achieve. That infinity is a feature, not a bug, from the perspective of the industry that sells the tools.
Three Practices Worth Trying
Practice 1: The Experience Check
Before consulting any data — sleep score, step count, weight, HRV — write two sentences about how you feel. Rested or not? Energetic or depleted? Do this for a week.
Then compare your experiential reports to your data. Notice where they diverge. The divergences are the interesting data. Not because the feeling is always right and the tracker is always wrong, but because your felt experience is supposed to be what this is all for. If the two are consistently pointing in opposite directions, something structural is worth examining.
Practice 2: The Ethics Question
Ancient care of the self was inseparable from questions about how to live. Try adding one question to any self-improvement practice: “Why does this matter?”
Not in terms of health metrics or longevity. In terms of what you’re trying to be or do in the world. If you can’t answer, that’s worth sitting with. Not to abandon the practice, but to understand whether you’re optimizing a metric or cultivating something that connects to a considered life.
Wabi-sabi’s approach to imperfection is useful here: the question isn’t whether you’ve achieved the target, but whether you’re attending to what actually matters with honesty and care.
Practice 3: The Relational Reframe
Identify one wellness practice you do entirely alone and in private. Then ask: is there someone you could share it with, or talk about it with?
Not to compare data. To make it conversational. To bring in the relational dimension that makes care of the self something other than surveillance. A walk with a friend beats a solo walk with a tracker — not because you get fewer steps, but because conversation is itself a practice of care.
What This Doesn’t Fix
Foucault’s framework is a critique, not a treatment plan.
If your sleep is genuinely disrupted, a tracker might surface something actionable. If you have a health condition, measurement matters. The critique isn’t that data is always bad — it’s that data-driven self-management has become the dominant frame for all self-care, including kinds that were never about measurement.
The critique also has limits by class. For many people, the option to stop optimizing and just attend to felt experience is a luxury. When your health outcomes depend on constant monitoring, when your job depends on maintaining certain performance metrics, the choice to step back from self-surveillance isn’t freely available. Foucault’s late work describes practices of freedom available to people who actually have some.
There’s something clarifying about realizing the thing you’re calling self-care might actually be self-surveillance.
Not because surveillance is always bad. But because the question “am I caring for myself?” and the question “am I monitoring my compliance with the standards I’ve internalized?” are genuinely different questions. The wellness industry tends to answer both at once, with the same app.
Foucault’s final contribution was to hold those questions apart. Care of the self — real care — is attentive, relational, ethically grounded, and aimed at transformation. It asks what kind of person you want to become, not what score you want to achieve.
The tracker knows your sleep efficiency. It doesn’t know what you’re trying to be.
