While You Were Sleeping
 
In the boardrooms and R&D labs of traditional MedTech companies, where discussions have long centred around legacy devices designed for hospital-based interventions, a transformation has been quietly taking place. While industry veterans - often digital immigrants - remained entrenched in familiar paradigms, focusing on incremental improvements to existing technologies, a new frontier of health innovation was unfolding beyond their traditional domain. The sleep technology market, once a niche sector, has surged forward, fuelled by cutting-edge wearables, sophisticated biometrics, and AI-driven data analytics.

This shift has been driven by a fundamental rethinking of health itself: sleep, once an afterthought in mainstream medical discourse, is now recognised as a cornerstone of physical and mental wellbeing. As research continues to highlight its critical role in metabolic regulation, cognitive function, emotional stability, and chronic disease prevention, consumer demand for sleep-enhancing solutions has skyrocketed. Meanwhile, a new breed of MedTech innovators - unburdened by legacy constraints - has seized this opportunity, developing advanced sleep monitoring and optimisation tools that bridge the gap between consumer wellness and clinical-grade diagnostics. In doing so, they have redefined the boundaries of MedTech, leaving many traditional players scrambling to catch up. While they were sleeping, the future of health technology evolved - without them.
 
In this Commentary

This Commentary delves into the rapid rise of the sleep MedTech market, a sector that has transitioned from a niche industry to a driving force in health innovation. It explores how advancements in AI, biometrics, and wearable technology have redefined sleep monitoring, blurring the lines between consumer wellness and clinical diagnostics. Highlighting key industry players, emerging market trends, and the evolving role of MedTech, the Commentary emphasises the need for traditional firms to adapt - or risk being left behind.
 
The Critical Role of Sleep in Health

Once regarded as a passive state of rest, sleep is now widely recognised as a critical pillar of health, as essential as diet and physical activity. It is no longer seen as a by-product of modern life but rather as a fundamental biological process that influences overall wellbeing. The timing, duration, and quality of sleep shape a wide range of health outcomes, from cognitive function to chronic disease prevention. Sleep plays a crucial role in metabolic regulation, helping to maintain hormonal balance, regulate appetite, and support glucose metabolism, thereby influencing conditions such as obesity and diabetes. It is equally important for emotional stability, as insufficient sleep is linked to heightened stress, anxiety, and mood disorders. Beyond its psychological effects, sleep is essential for cognitive performance, memory consolidation, and learning, enhancing problem-solving abilities and decision-making processes. Neurologically, it serves as the body’s natural maintenance system, facilitating the removal of metabolic waste from the brain and playing a potential role in neurodegenerative disease prevention.

Despite mounting scientific evidence highlighting the health implications of sleep, mainstream medical practice and public health strategies have been slow to give it the attention it deserves. MedTech leaders, preoccupied with acute interventions and reactive care models, have historically overlooked sleep as a key determinant of health. This neglect has created an opportunity that innovative companies have seized, leveraging technology to quantify, analyse, and optimise sleep. In doing so, they have not only addressed a long-ignored health imperative but also reshaped the landscape of MedTech itself.
 
The Rise of the Sleep Tech Market

The global sleep technology market has undergone a transformation, evolving from a niche category into one of the fastest-growing segments in health technology. Valued at ~$23bn in 2025, it is projected to surge to ~$69bn by 2032, expanding at a compound annual growth rate (CAGR) of ~17%. Such rapid growth reflects a shift in how sleep is perceived - not as a passive biological function, but as a significant determinant of long-term health and performance.

Several factors have fuelled this expansion. Heightened public awareness of sleep’s role in overall health has driven a demand for tools that monitor and enhance sleep quality. As consumers become more proactive about their wellbeing, they are increasingly seeking solutions that go beyond traditional sleep aids, favouring advanced, technology-driven approaches. The proliferation of wearable technology has further accelerated this trend, with devices such as smart rings, wristbands, and smart beds offering real-time data on sleep cycles, heart rate variability, and nocturnal movement. The integration of AI and machine learning has added another dimension, enabling personalised, data-driven insights that allow users to fine-tune their sleep patterns. Together, these forces are reshaping the MedTech landscape, establishing sleep technology as an essential and lucrative frontier - one that traditional MedTech leaders can no longer afford to ignore.
 
Pioneering Companies in Sleep Technology

The landscape of sleep technology is rapidly evolving, driven by companies that blend science with user-centric innovation. These pioneers are reshaping how people understand, monitor, and optimise their sleep, leveraging advancements in AI, biometrics, and neurotechnology. Here are a few examples:

Oura Health: Founded in 2013 in Finland, Oura Health has established itself as a leader in wearable sleep tracking through its flagship product, the Oura Ring. This sensor-packed smart ring provides continuous monitoring of sleep stages, heart rate variability, temperature fluctuations, and overall recovery metrics. With >2.5m units sold worldwide, Oura has built a loyal customer base, with the US as its largest market followed by the UK. The company continues to refine its algorithms, integrating personalised insights and readiness scores to help users optimise their rest and recovery.

Eight Sleep: Positioning itself at the intersection of sleep and fitness, Eight Sleep has transformed the mattress industry with its Pod technology. This intelligent sleep system adjusts temperature throughout the night, catering to individual preferences and responding to environmental changes. With the launch of its fourth-generation Pod in 2024, Eight Sleep has expanded into new global markets, including the United Arab Emirates, underscoring the growing demand for data-driven sleep optimisation.

ResMed: A dominant force in sleep apnoea treatment, ResMed has embraced the rise of wearable and smart technology to enhance sleep disorder management. The company’s success is reflected in its 10% revenue growth to ~$1.3bn in 2024, partly fuelled by the increased awareness of sleep health driven by integrations with smart phones, such as those of Apple and Samsung and other consumer tech giants. By leveraging cloud-based connectivity and AI-driven diagnostics, ResMed is making strides in improving access to personalised sleep therapy.

Blurring the Lines: Medical Devices and Consumer Wearables

The distinction between medical devices and consumer wearables is becoming increasingly fluid, as consumer technology integrates medical-grade capabilities and clinical devices adopt user-friendly designs. Wearables that once focused on fitness tracking now provide FDA-cleared health insights, while traditionally complex medical devices are evolving into intuitive, everyday tools. This convergence is fuelled by several factors.

First, cost reduction has made advanced health monitoring more accessible, thanks to improvements in sensor accuracy, miniaturisation, and processing power. What was once confined to hospitals - such as continuous glucose monitoring or ECG tracking - is now available in a sleek, wrist- or finger-worn format. Second, rising consumer health literacy has driven demand for self-monitoring tools, with individuals proactively managing their sleep, heart health, and stress levels through smart devices. Finally, the increasing prevalence of chronic diseases, such as diabetes and hypertension, has accelerated the need for at-home monitoring solutions that reduce healthcare burdens and empower patients.

For traditional MedTech companies, this shift presents both challenges and opportunities. Competing with agile tech firms requires a more consumer-centric approach, balancing clinical rigour with user experience. Those willing to innovate beyond conventional models - integrating AI, cloud connectivity, and personalised insights - will be well-positioned to lead the next evolution of digital health.
