For most of human history, sleep was the one thing you could not buy. You lay down, and either it came or it didn't. In 2026 that is no longer quite true. Sleep tourism — booking a trip whose entire purpose is to rest — has been named one of the year's defining travel trends, with hotels and resorts selling blackout suites, circadian lighting and "sleep concierges" [source: Grand View Research, 2025]. At the same time, the National Sleep Foundation's 2025 poll found that six in ten American adults still do not get the recommended seven to nine hours of quality sleep, and nearly four in ten struggle to fall asleep at least three nights a week [source: National Sleep Foundation, 2025]. That is the paradox worth opening with: we are spending more on sleep than ever, and sleeping no better.
This article maps the sleep economy — mattresses and smart beds, wearables and apps, supplements, and sleep-focused travel — and tries to keep three lines sharp throughout. First, the line between validated sleep science and marketing claims. Second, the line between the "estimated" sleep score on your wrist and the "measured" data of a clinical sleep lab. Third, the point at which chasing better sleep starts to make it worse. None of this is medical advice; if sleep problems persist, that is a conversation for a clinician, not a checkout cart.

Why we started paying to sleep
The commercial case for sleep rests on a genuine finding: sleeping badly is expensive. A widely cited RAND Europe analysis estimated that insufficient sleep costs the United States up to US$411 billion a year — about 2.28% of GDP — through lost productivity and higher mortality risk, with the country shedding roughly 1.2 million working days annually [source: RAND Europe, 2016]. The same model suggested that nudging people who sleep under six hours up to six or seven could add about US$226 billion to the US economy [source: RAND Europe, 2016]. Those are modelled estimates, not measured invoices, and the study dates from 2016 — but the direction is hard to argue with, and it reframed sleep from a personal habit into an economic input.
Culture caught up with the accounting. Sleep now sits inside the broader "wellness economy," which the Global Wellness Institute valued at US$6.8 trillion in 2024 and expects to reach US$9.8 trillion by 2029 [source: Global Wellness Institute, 2025]. Within that, sleep is one of the fastest-moving pieces: the Institute reports the sleep sub-segment of mental wellness grew about 12.6% a year between 2019 and 2024 [source: Global Wellness Institute, 2025]. It is worth noting what that figure is not — the Institute does not publish a single clean "sleep market" number, so anyone who quotes one is stitching together sources. Still, the pattern is clear: rest has been repackaged as something you invest in, optimize and, increasingly, purchase.
What the sleep economy actually sells
The sleep economy is really four overlapping markets, and their sizes should be read with caution — most figures come from commercial market-research firms, and they vary enormously depending on how each defines the category.
The oldest pillar is mattresses and smart beds. Estimates for the global mattress market cluster somewhere between US$49 billion and US$58 billion for 2024–2025, growing around 7% a year, though different firms disagree by billions [source: Grand View Research, 2025]. Layered on top is a newer category of "smart" beds and sleep-optimized bedding that promise temperature control and posture sensing.
The second pillar is wearables and apps — the rings, watches and mats that turn a night's sleep into a score. Sleep-tracking hardware is the visible face of the category, and wearables make up the large majority of it, but the crucial point here is not size but function: these devices sell a number, and that number is an estimate, which the next sections take apart.
The third pillar is supplements, led by melatonin. The melatonin supplement market has been valued in the low single-digit billions of dollars, with firms projecting brisk double-digit growth [source: Grand View Research, 2025]. Melatonin is a hormone the body already makes to signal night; taking it can help with circadian problems such as jet lag, but the evidence for it as a general sleeping pill is far thinner than the shelf space suggests.
The fourth and newest pillar is sleep tourism. Hotels accounted for roughly 46% of the sleep-tourism market in 2024, and analysts project low-double-digit annual growth through 2030 [source: Grand View Research, 2025]. The offer ranges from a quiet room with good curtains to medical-grade retreats with sleep assessments and coaching.
Two things are true at once about all of this. Some products genuinely help — a better mattress, a dark room, a consistent wind-down routine are real inputs to real rest. And the category has strong incentives to sell certainty about something inherently uncertain. Holding both ideas together is the whole game.
What works: science versus marketing
Here the layers matter most, because the gap between what sleep scientists endorse and what the market promotes is wide.
Start with the good news that no one is selling, because it is free. The behavioral basics — a regular schedule, a cool dark room, limiting late caffeine and alcohol, and getting out of bed when you cannot sleep — are the substance of "sleep hygiene." But the clinical evidence adds an important asterisk. For chronic insomnia, the American Academy of Sleep Medicine's guideline makes cognitive behavioral therapy for insomnia (CBT-I) its strong, first-line recommendation, while noting that sleep hygiene on its own is not an effective standalone treatment [source: American Academy of Sleep Medicine, 2021]. In other words, the tips the internet gives away for free are helpful habits, but the treatment with the strongest evidence is a structured therapy — not a gadget, a mattress or a tea.
Melatonin is the sharpest example of the science-versus-marketing gap. It can genuinely help reset a body clock knocked off by travel or shift work, but it is not a sedative, and long-term safety data beyond a few months is limited. More troubling is what is actually in the bottle. A 2017 study in the Journal of Clinical Sleep Medicine analyzed commercial melatonin products and found the actual melatonin content ranged from 83% below to 478% above the labelled dose; more than 70% of products missed their own label by more than 10%, and some contained serotonin as a contaminant [source: Journal of Clinical Sleep Medicine, 2017]. Because supplements are lightly regulated, the dose on the label is a claim, not a guarantee — a distinction the packaging rarely makes.
The honest summary is deflating for anyone hoping to buy their way to rest: the interventions with the best evidence are behavioral and clinical, and the products that dominate the market range from genuinely useful to unproven.
Your sleep score versus the sleep lab
Nothing captures the sleep economy better than the morning ritual of checking your "sleep score." It feels like data. It is, more precisely, an estimate — and it is worth understanding how far that estimate can drift from what a clinic would measure.
The clinical gold standard is polysomnography: an overnight lab study that records brain waves, eye movement, muscle activity, breathing and heart rhythm to score sleep stages directly. A consumer wearable has none of that. It infers sleep mostly from movement and heart rate, then models the rest. When researchers put this to the test in a 2023 multicenter study comparing 11 consumer trackers against polysomnography, performance varied widely: agreement scores for classifying sleep stages ranged from poor to moderate across devices, with some showing substantial agreement and others only partial [source: JMIR mHealth and uHealth, 2023]. The characteristic failure is revealing — because the devices lean on movement, they tend to mistake lying still for being asleep, overestimating sleep for exactly the people most worried about it, such as insomniacs who lie awake without moving [source: JMIR mHealth and uHealth, 2023].
The educational arm of the National Sleep Foundation adds two cautions worth repeating: consumer sleep trackers are not regulated by the FDA as medical devices, and even newer models are only moderately good at identifying sleep stages, with one cited study finding trackers correctly identified deep sleep around 59% of the time [source: Sleep Foundation, 2024]. The fair conclusion is not that trackers are useless. For spotting trends over weeks, nudging an earlier bedtime, or raising awareness, they can genuinely help. But a nightly score is a modelled estimate, not a diagnosis — and the two belong in separate columns.
When chasing sleep backfires: orthosomnia
There is a failure mode specific to the quantified approach, and it has a name. In 2017, researchers writing in the Journal of Clinical Sleep Medicine coined "orthosomnia" to describe patients whose pursuit of perfect sleep — driven by their tracker data — was paradoxically making their sleep worse [source: Journal of Clinical Sleep Medicine, 2017]. The anxiety of chasing a better score becomes its own cause of insomnia.
How common is it? The honest answer is that we are still measuring. A 2024 cross-sectional study in Brain Sciences surveyed 523 adults and found that about 36% regularly used sleep trackers; depending on how strictly orthosomnia was defined, its estimated prevalence ranged from about 3% under the most conservative criteria to 14% under the most lenient [source: Brain Sciences, 2024]. Those numbers deserve a caveat the headlines skip: the sample skewed young and heavily female, so it is a signal, not a settled statistic. Reporting elsewhere suggests younger adults are the most susceptible to tracker-induced sleep stress.
This is not an argument against measuring your sleep. For many people, a tracker is a harmless and even motivating tool. It is an argument for holding the number loosely — the moment a device meant to improve your rest becomes a reason to lie awake grading it, the product has begun working against its own promise.
What to watch
The sleep economy is built on something real. Sleeping badly carries genuine costs, a majority of adults fall short of the rest they need, and some of what the market sells — a dark room, a decent mattress, a structured therapy — genuinely helps. But the same evidence counsels a buyer's skepticism. Market sizes are estimates that swing by billions between sources; the score on your wrist is a model, not a measurement; the supplement's label is a claim, not a guarantee; and the strongest treatment for chronic insomnia is a behavioral therapy that no one can package and ship.
A few things are worth watching from here. Will regulators bring supplement labelling and "sleep score" marketing under tighter scrutiny as the category grows? Will wearable accuracy close the gap with clinical measurement, or will the marketing outrun the science? Will sleep tourism mature into evidence-based programs, or settle for luxury with a wellness label? And culturally, will the quantified pursuit of perfect sleep keep feeding the very anxiety that ruins it? The most useful thing a reader can carry away is not a product recommendation but a habit of mind: separate the science from the sale, the estimate from the measurement, and the rest you need from the rest someone is trying to sell you.
