World Sleep Day, the annual spotlight on sleep health that promotes education, research and patient care, is being held on March 14. Withings is marking the occasion by highlighting the extensive technology development and research the company is doing to promote better sleep and more accessible sleep diagnostics.
Because sleep affects so many chronic conditions - from diabetes, stroke and heart disease to obesity, anxiety and depression - higher quality sleep is one of the few areas of impact that can universally change human health for the better.
That’s why the Withings team has spent its waking hours for the past several years developing and testing technology to improve global sleep quality. In September, Withings Sleep Rx was given FDA clearance as the first contactless device to aid in the diagnosis of sleep apnea, joining the Withings Sleep Analyzer, a device that is CE marked to diagnose sleep apnea in the EU.
Sleep Rx and the other Withings devices that use the same hardware are being used in major sleep studies around the world. Because the devices are contactless and lay under the patient’s mattress, they enable large-scale studies that would previously have been nearly impossible to conduct. Here is just a sampling of recent research using or related to Withings sleep devices.
Cognitive Performance of Critical Shift Workers
Non-daytime shift workers - like nurses, firefighters, mariners, military personnel and transit drivers - have a 60% greater risk of workplace accidents. Using Withings Sleep Analyzer, which uses the same hardware technology as Sleep Rx, researchers were able to understand the cognitive impacts of different lighting conditions to develop a model for predicting performance under varying sleep conditions and time of day of the sleep.
Results supported the utility of simple non-intrusive sleep monitoring via consumer sleep technology to estimate post-sleep work shift performance and safety during non-daytime shift schedules.

How Many Nights of Sleep Data Do We Really Need?
An article in JMIR Formative Research examines how traditional sleep assessments rely on short-term tracking (3–14 days), while a six-month study using Withings’ wearables and sleep sensors suggests this may not be enough. Researchers found that seasonal variations and long-term patterns significantly impact sleep health, reinforcing the importance of continuous monitoring to gain a more accurate picture of sleep behaviors.

The Future of Sleep Research: Large-Scale, Decentralized Studies
An article in Current Sleep Medicine Reports details how the growing adoption of wearable and nearable sleep tech is enabling researchers to shift toward real-world, long-term data collection. Ongoing studies using Withings technology are paving the way for remote clinical trials, enabling deeper insights into sleep disorders and their broader health impacts.

Up to 30% of adults experience intermittent or chronic insomnia; 20% suffer from sleep apnea, although up to 80% of them are unaware and undiagnosed.1 Poor sleep and sleep disorders like Obstructive Sleep Apnea, have been linked to obesity, diabetes, hypertension, coronary artery disease, dementia, cardiovascular mortality, seizures, stroke, congestive heart failure, lowered immune response, and impaired judgment and reaction times. With such widespread prevalence and dire consequences, the theme of World Sleep Day 2025: MAKE SLEEP HEALTH A PRIORITY is an imperative.
Polysomnography, either in a lab or at home, is the clinical gold standard for measuring sleep health, but these studies can be expensive, inaccessible and difficult to schedule. They are usually single-night observations which rely on human interpretation of data and do not capture variability in sleep quality over multiple nights. Withings Sleep Rx is a discreet mat placed under the mattress which captures many of the same metrics as polysomnography with longitudinal, contact free monitoring in a real-world setting.
Sleep Rx is the first contactless, in-home sensor to aid in diagnosing Obstructive Sleep Apnea. This is measured and scored using the Withings Index. The Withings Index uses heart rate and breathing inputs (both sound and variations of pressure in the bladder) to calculate an estimated frequency of adverse breathing events per hour during the night. Clinical validation of the Withings sleep mat shows good agreement with polysomnography-derived Apnea-Hypopnea Index (AHI) with high predictive performance (88% sensitivity and 88% specificity) to classify moderate to severe OSA .2
Sleep Rx continuously tracks heart rate with ballistocardiographygraphy (BCG) using a pneumatic sensor that measures the mechanical wave that each heart beat sends through the body. BCG has been validated against ECG and found to be highly accurate .3 Variability in heart rate can be used to detect sleep phases .4 Nocturnal heart rate is comparable to resting heart rate and is a good indicator of overall cardiovascular health 5.
The Withings sleep mat also incorporates a snoring algorithm which crosses breathing rate and audio signals to identify snoring patterns and differentiate them from environmental noises or a partner’s snoring. The algorithm has been shown to be 94.4% precise with a 75.9% recall 6.
In addition, the sleep mat analyzes movement, interruptions, sleep onset latency, duration, regularity, and efficiency. With a one-time set up, the mat automatically syncs data via WiFi with the HIPAA-compliant Withings API and integrates with the Withings Remote Patient Monitoring platform. Sleep Rx is available by prescription in the US.
The ease of use of Sleep Rx combined with its sophisticated and robust metrics make it an ideal tool for capturing sleep variability over multiple nights. This cutting edge technology presents exciting clinical research applications, opportunities to optimize treatment adherence, and the ability to enhance the precision of personalized sleep medicine.

[post_title] => Withings Sleep Rx: Allowing Sleep Specialists to Make House Calls
[post_excerpt] => New large-scale, longitudinal studies show that monitoring sleep for at least 14 nights at home with a connected sleep tracking mat, can reduce the 30% high error rate of sleep apnea diagnosis from the usual single-night, in hospital polysomnography (PSG) technique. This technology can identify which patients most need expensive, intrusive, and difficult to access PSG. Longitudinal data also detects variability of Obstructive Sleep Apnea from night to night which is associated with hypertension

Professor Danny Eckert of the Adelaide Sleep Institute at Flinders University didn’t set out to be one of the world’s foremost sleep experts. He started as an elite cyclist, representing Australia at the World Championships. Wanting to use his head as well as his body, he studied exercise physiology and sports science in the afternoons, trained on his mountain bike in the mornings, raced competitively, and presumably left some time for sleep. After receiving his degree, he was offered a prestigious appointment with the South Australia Sports Institute.
But on the Friday before he was due to start his internship, he was also offered a 3-year position with a respiratory and sleep unit in a hospital. When he reported for his new job at the Sports Institute on Monday, he immediately asked his new boss if he could take a walk to consider his options, came back, and left for a field he knew nothing about. “It turned out that everything I’d learned about the body being at its most vulnerable and physiologically interesting when you push it as hard as you can during exercise is also true when you are sleeping and the body is at its quietest.”
Professor Eckert was on fertile ground for his newly chosen field. Australia has long been a leader and innovator in sleep science, especially in respiratory medicine. When he started studying sleep apnea, the research centered on anatomy: the collapse of the upper airway, especially due to obesity. As such, treatments such as Continuous Positive Airway Pressure, (CPAP, invented in Australia), mouthguards, and surgery were designed to open the airway.
Professor Eckert’s groundbreaking work changed nearly everything we thought we knew about sleep apnea. Importantly, he identified three nonanatomical endotypes that can cause sleep apnea. Between them, they account for 70% of sleep apnea cases.
1) Low Arousal Threshold: Light sleepers who wake up when their muscles relax.
2) Instability in Breathing Control: Sleepers who are too sensitive to minor changes in carbon dioxide. Their overactive respiratory system turns off their drive to breathe.
3) Poor Muscle Responsiveness to the Narrowing Airway
Simplified, scalable diagnostic tools and machine learning can identify the endotype(s) that causes a particular patient’s sleep apnea. Endotypes can inform targeted therapies and lead to an 80% success rate for treating sleep apnea. This individualized, precision medicine approach includes emerging pharmaco-therapies, such as drugs that can activate the muscles, or strategies, such as cognitive behavioral therapy, that can help light sleepers.
What’s next? With 70 researchers working on 40-50 studies at any one time at the Adelaide Sleep Institute, there are many exciting developments to come. One area of interest is sleep irregularity. Researchers have found varying bedtime by even 30 minutes throughout the week is associated with a 30% higher chance of hypertension; vary by 90 minutes and increase the odds by 90%, regardless of the total amount of sleep.
New technologies that allow longitudinal data are especially useful for studying sleep variability. Combining sleep data with measures like body fat, step counts, and blood pressure will allow for quicker treatment changes, better monitoring of treatment effectiveness, and reach many more people who suffer from sleep disorders.
The three pillars of health are exercise, diet, and sleep, but sleep directly affects the other two. Not getting sufficient or quality sleep makes us crave bad food and makes it hard to exercise. That’s why Dr. Eckert believes sleep is the foundation for optimal health. Through research and scientific and technological breakthroughs, Professor Eckert thinks we are at the precipice of transforming the entire sleep field. That’s a comforting thought for the billions of people around the globe desperate for a good night’s sleep.
