Sleep technology, or sleep tech, comprises digital and electronic products and services designed to measure, interpret, influence, diagnose or treat sleep. It includes sleep-tracking wearables, smartwatches, fitness trackers, smart rings, smart mattresses, adjustable beds, contactless monitors, sleep apps, digital coaching platforms, smart alarm clocks, environmental sensors, connected lighting and temperature-control systems, and medical-grade diagnostic and therapy devices.

These products serve different purposes. Consumer trackers generally estimate sleep for wellness, while connected-bedroom products adjust comfort or environmental conditions. Medical-grade devices must satisfy applicable clinical and regulatory requirements. Sleep-related healthcare services involve professional diagnosis, monitoring or treatment.

Sleep tech is also narrower than the broader sleep economy, which may include conventional mattresses, bedding, pharmaceuticals, supplements, clinics and hospitality services.

There is no universally accepted definition of the sleep-tech market. Estimates vary because research firms include different devices, services, customers and points in the supply chain.

The Business Research Company’s January 2026 report, distributed by Research and Markets, estimated the global sleep-tech device market at $25.26 billion in 2025. It estimated $29.62 billion for 2026 and forecast $57.47 billion by 2030. The definition is broad, covering wearables, bed sensors, smart mattresses, monitors, smart alarms, therapy machines, apps, online sleep programs, white-noise devices and smart lighting. The figures represent factory-gate product value and related services, not audited retail spending across the entire sleep economy. The 2026 and 2030 figures are modeled estimates and forecasts.

A narrower Fortune Business Insights study estimated the sleep-tracker market at $6.76 billion in 2025 and $7.74 billion in 2026. Its scope includes watches, bands, rings and other devices using technologies such as actigraphy, heart-rate variability, oximetry and polysomnography-linked systems. It does not represent the full smart-bedroom or sleep-app market.

Grand View Research separately estimated the smart-bed market at $2.9 billion in 2025 and $3.1 billion in 2026. Its definition includes residential, hospital and hospitality beds; residential products represented an estimated 71.7% of 2025 revenue.

These figures cannot be added together because their categories overlap. This article also omits Fortune’s and Grand View’s longer-term forecasts because calculations based on their published endpoints produce growth rates of approximately 15.8% and 8.3%, respectively, rather than the 13.2% and 6.3% compound annual growth rates displayed on their pages.

Adoption data provide a different measure. In an AASM-commissioned online survey of 2,007 U.S. adults conducted by Atomik Research from June 5–13, 2025, 48% reported having used a sleep-tracking device, up from 35% in the 2023 survey. The stated margin of error was plus or minus two percentage points at the 95% confidence level. These are self-reported individual-use figures, not active ownership, household penetration or annual shipments.

Demand begins with widespread concern about insufficient sleep. An age-adjusted 33.2% of U.S. adults reported sleeping fewer than seven hours per 24-hour period in the 2020 Behavioral Risk Factor Surveillance System, according to the CDC. The result was based on self-reported duration rather than clinical measurement.

The National Heart, Lung, and Blood Institute links sleep deficiency with reduced concentration and functioning and with chronic conditions including heart disease, hypertension, diabetes, stroke, obesity and depression. These associations have helped establish sleep as an important part of health alongside nutrition and physical activity. They do not, however, prove that buying a tracker will prevent disease or improve sleep.

Wearables brought sleep monitoring into everyday life by collecting information passively over multiple nights. Accelerometers measure movement, optical sensors estimate heart rate, and some products add temperature, respiratory or blood-oxygen information. Algorithms use these indirect signals to estimate sleep duration, timing and stages.

Apple Watch, Google Fitbit and Pixel Watch, Samsung Galaxy devices, Garmin watches and Oura rings all connect sleep with broader activity, stress and recovery information. Apple introduced a sleep score with watchOS 26 in September 2025. Samsung’s Energy Score combines sleep with activity, sleeping heart rate and heart-rate variability, while Garmin provides sleep scores and individualized sleep-need recommendations.

The distribution platform is substantial. IDC reported 45.6 million wrist-worn devices shipped globally in the first quarter of 2025, up 10.5% from the first quarter of 2024. That figure covers all wrist-worn devices and should not be interpreted as sleep-tracker shipments or active users.

Smart beds move sleep tech from observation toward physical adjustment. Products can change firmness, elevation or temperature while embedded or under-mattress sensors monitor movement, heart rate and respiration.

The connected bedroom also includes circadian lighting, thermostats, air-quality sensors, noise monitors, smart blinds, sound machines and alarms that gradually change light or sound. These products automate established sleep-hygiene principles such as maintaining a dark, quiet and comfortable room, but clinical benefits must still be established for each product.

Growth is not uniform. Sleep Number reported $1.411 billion in net sales for fiscal 2025, the 53 weeks ended January 3, 2026, down 16% year over year amid industry pressure and lower store traffic. The company filed for Chapter 11 on June 12, 2026, and a bankruptcy court approved a sale of its assets to Sleep Country Canada in July 2026. Its difficulties demonstrate that a growing technology category does not guarantee success for every manufacturer.

Artificial intelligence is central to consumer sleep tracking because most products do not measure brain activity directly. Machine-learning systems combine movement, heart rate, respiratory signals and historical baselines to estimate sleep stages, identify patterns and generate recommendations.

Samsung uses sleep and activity data in Energy Score. Garmin adjusts suggested sleep needs using recent sleep, activity, naps and heart-rate variability. Google introduced a Gemini-based Fitbit health coach in public preview in October 2025, offering personalized fitness and sleep guidance. Eight Sleep’s Autopilot uses sensor feedback to adjust bed temperature automatically.

These systems can make complex data easier to interpret, but AI-generated wellness guidance does not automatically constitute medical advice. Diagnostic or treatment claims still require appropriate clinical evidence and regulatory authorization.

Sleep tech is increasingly entering regulated healthcare through home sleep tests, remote monitoring and connected therapy.

The FDA granted De Novo authorization to Samsung’s Sleep Apnea Feature on February 6, 2024, and cleared Apple’s Sleep Apnea Notification Feature on September 13, 2024. Both are over-the-counter tools intended to identify patterns suggesting moderate-to-severe sleep apnea in previously undiagnosed adults. Neither is a standalone diagnosis or replacement for polysomnography.

Connected therapy is already operating at large scale. ResMed reported an installed base of more than 30 million patients using cloud-connected devices through AirView and more than 10 million patients registered with myAir as of June 30, 2025. AirView covers ResMed’s sleep-apnea and broader respiratory-care ecosystem, so the figures should not be treated as consumer sleep-tracker adoption.

Digital treatment also requires careful distinctions. The AASM strongly recommends multicomponent cognitive behavioral therapy for chronic insomnia, but that evidence does not validate every meditation, coaching or sleep app sold to consumers.

Sleep tech offers convenience and personal relevance. Data can be collected passively, viewed on a familiar smartphone and combined with information about exercise, stress and recovery. Rings and watches are less conspicuous than traditional medical equipment, while contactless monitors appeal to people who do not want to wear a device overnight.

The category also spans free apps, multipurpose wearables, dedicated rings and beds costing thousands of dollars. Subscription services give users coaching, longer data histories and software updates, while providing companies with recurring revenue. Smartphone and smart-home integration can connect sleep monitoring with alarms, lighting, temperature and other bedroom controls.

Investment reflects expectations that sleep data can support businesses combining hardware, software and subscriptions.

Oura announced more than $900 million in funding at an approximately $11 billion valuation on October 14, 2025. The company also reported more than 5.5 million rings sold cumulatively since 2015 and more than $500 million in 2024 revenue. These are company-reported figures rather than audited market totals.

Eight Sleep announced $100 million in new funding on August 19, 2025 and reported more than $500 million in cumulative Pod sales at that date. ResMed expanded in the opposite direction—from medical therapy into more integrated home diagnostics—by acquiring VirtuOx in May 2025.

Competition now spans consumer-technology platforms, wearable specialists, medical-device companies, mattress manufacturers, app developers and healthcare providers.

Polysomnography records brain waves, eye movement, muscle activity, breathing and oxygen levels. Most consumer trackers infer sleep from fewer and less direct signals.

A prospective study published on November 2, 2023, compared 11 wearable, contactless and phone-based trackers with laboratory polysomnography. Among 75 participants at two South Korean institutions, sleep-stage macro F1 scores ranged from 0.26 to 0.69. Participants were generally assessed during one laboratory night, and the number tested with each device ranged from 22 to 75. The results demonstrate substantial differences between products and should not be generalized automatically to later device models or software versions.

Other limitations include high hardware prices, recurring subscriptions, proprietary scores, limited interoperability and insufficient evidence that every product meaningfully improves sleep rather than merely measuring it. Regulatory authorization applies only to the reviewed feature, intended population and stated use.

Privacy protections also vary. HHS explains that HIPAA generally does not protect information entered into a personal app unless the app is provided by a covered entity or its business associate. FTC amendments effective July 29, 2024, clarified breach-notification obligations for many health apps and connected-device businesses outside HIPAA.

Finally, excessive attention to scores can become counterproductive. “Orthosomnia” is a proposed clinical term—not a recognized standalone diagnosis—introduced in a 2017 three-case paper describing efforts to perfect wearable-generated sleep data.

Sleep technology has become a multi-billion-dollar market because it combines widespread concern about sleep with accessible sensors, connected bedrooms, personalized software and home-based healthcare.

Future growth will depend on more than device sales. Companies will need to demonstrate credible benefits, improve affordability and interoperability, protect sensitive information and maintain clear boundaries between consumer wellness, clinical assessment and regulated treatment.
