▲ Securing computational design data through 4D scanner

Developing wearables with the optimal fit and comfort remains a difficult yet crucial challenge. Not only do these factors make the device feel more seamless to use, but they are directly tied to maximising overall performance and sensor accuracy. However, the fact that each person’s anatomy is completely unique presents a major hurdle. But what if there was a way to meticulously engineer comfort, fit and sensing so precisely, it could deliver the optimal experience for nearly everyone?

Samsung’s solution is Computational Design. This multidimensional process harnesses AI and advanced computing to analyse hundreds of thousands of quantitative and qualitative data points to generate, test, and refine product designs with greater precision. The result is a fundamental shift from subjective feedback to objective, data-driven engineering, creating superior products with the optimal fit for the widest range of users.

That description captures computational design in the abstract—like a dictionary definition. To understand how computational design is actually used to create superior wearables, Samsung Newsroom visited the Samsung Design Innovation Center (SDIC) in San Francisco, home to the Computational Design Lab.

▲ Federico Casalegno, EVP and Head of the Samsung Design Innovation Center

Spearheading the SDIC is Federico Casalegno, Executive Vice President and Head of the Samsung Design Innovation Center, who has spent the past two decades mastering the practice of computational design and leading the implementation of this core concept into Samsung’s product development. We sat down with Federico to discuss how SDIC employs computational design as a primary tool to create and optimise experiences for Samsung’s wearables, particularly the Galaxy Buds4 series.

Q. Tell us about SDIC’s role.

At SDIC, our mission is to deliver meaningful experiences by understanding people and their evolving lifestyles—always in the context of human-centered design. Ultimately, we want to delight customers and create products that help people live happier, healthier, more creative, and more productive lives, while building a better future for all and preserving the environment.

To achieve this, SDIC brings together the power of design and creativity with data-driven decision-making. Supported by AI, machine learning, robotics, and advanced computing, our talented, multidisciplinary team of designers is constantly pushing the boundaries of what’s possible, delivering unparalleled user experiences and real, tangible benefits.

▲ At SDIC, design is combined with AI, data, and computing to achieve maximum comfort for wearable devices.

Q. What exactly is computational design, and what is the philosophy behind it?

While we live in a unique era of technological innovation, Samsung’s approach to design was always deeply human-centered as we believe that technology without humanity is merely perfection without purpose.

Computational design is how we bring this philosophy to life—it is the process of harnessing the immense power of AI, data, and computing to design products for people, rather than expecting people to adapt to our products. This approach helps us to create devices that are fundamentally functional, intuitive, comfortable and beautifully crafted. Today, this methodology is applied all across our wearable portfolio, including Galaxy Watch8 and Galaxy Buds4 series.

▲ The computational design process involves various state-of-the-art testing equipment, including 4D scanning.

Q. How does computational design turn the ‘fit’ of a device into an objective, measurable metric?

For developing something as personal as a wearable that remains in contact with you for extended periods, fit is an essential element. It’s not just about comfort though; a secure fit is also needed for maximising the precision of the device’s sensors. However, traditional design methods fail to measure wearability objectively, as they only rely on a small sample of people for product testing.

Computational design fundamentally changes this. By leveraging massive, digitalised datasets and advanced AI simulations, it transforms wearability into a quantifiable metric that allows Samsung to measure comfort and fit like never before. By being able to consider all the unique shapes and curves of the human ear or the wrist through computational design, our designers are equipped with trustworthy, objective insights that are difficult to attain through traditional methods.

▲ Optimal design parameters are derived through AI and physics-based simulations, which are then cross-verified with robot testing.

Q. Tell us in detail how the computational design process works in the lab, and how it was implemented in the Buds4 series.

Our computational design process relies on three elements: real people, digital twins, and robots. We capture 3D and 4D scans of a diverse global audience, integrating precise anatomical data to create ‘digital twins.’ We then run AI and physics-based simulations, cross-validating the results with physical robot testing.

For the Buds4 series, we applied this exact process to achieve perfect wearing comfort and premium sound. We analysed hundreds of millions of global ear data points and ran more than 10,000 simulations to perfect the new blade design. This objective data led us to subtly reduce the size of the main head^[1] and refine the angle of rotation—minor adjustments that resulted in a dramatic, universally validated increase in stability and comfort.

Q. How does Samsung’s computational design ultimately benefit the users?

Samsung’s computational design process is powered by a unique proprietary dataset built exclusively from within Samsung, and our team has developed several specialised AI programs based on this data. This combination gives us unique insights while we constantly innovate our design processes and methods. For Galaxy Buds and Watch specifically, this translates into improved wearing comfort, stability and sensor accuracy—key factors that elevate both the user experience and product performance.

▲ Optimal design parameters are derived through AI and physics-based simulations, which are then cross-verified with robot testing.

Q. Looking ahead, how do you see Computational Design evolving over the next decade?

Computational design is now a foundational element of Samsung’s development process across all our wearable products. Our goal remains to maximise wearability, fit, comfort and sensor performance to ultimately serve the people using it.

Looking ahead, the true power of this process is its continuous evolution. As our dataset continues to grow, custom AI tools will drive more accurate simulations and deeper insights. These advancements will not only further improve product wearability, but also unlock exponential innovations down the line that lead to an entirely new category of wearables that can redefine the boundaries of user experience. Ultimately, this symbiotic partnership between computational design and AI frees our designers to be more creative, empowering us to deliver measurably superior products and experiences for the people who use them.

Samsung Electronics Co., Ltd. today announced a major update to the Samsung Health app, transforming the upcoming Galaxy Watch into a proactive, intelligent health partner. Starting June 8, Samsung will begin rolling out the app update to showcase the key health features included in the upcoming Galaxy Watch. The update makes daily health management effortless by translating complex biometric data — from overnight sleep to daily activity — into simple, actionable guidance.

“Samsung Health is evolving to connect health data measured by Galaxy Watch with AI-based insights, enabling users to understand their physical and mental condition more easily and intuitively,” said Hon Pak, Senior Vice President and Head of the Digital Health Team for the Mobile eXperience (MX) Business at Samsung Electronics. “Samsung Electronics will continue to expand proactive and personalised health management experiences based on the connected Galaxy ecosystem and digital health innovations.”

This advancement is a key milestone in Samsung’s overarching vision for a truly AI-powered health platform designed to help users stay ahead of their health. The newly announced health features will first be available on the upcoming Galaxy Watch.

Features Transforming Galaxy Watch into an Intelligent Health Partner

The Samsung Health update comes with the following features:

• Vitals: A Better Understanding of the Body’s Signals^[1] — Previously, Samsung Health monitored specific health metrics to help measure users’ daily Energy Score. Now, Samsung Health is taking this a step further. When users wake up, the new Vitals feature analyses five key overnight bio-signals — heart rate, heart rate variability, respiratory rate, skin temperature and blood oxygen — against their true resting baseline. It sends notifications only when it detects meaningful deviations, helping users determine if they need more rest or are fighting an illness, without causing alert fatigue.

• Heart Health Score: Improved Long-Term Wellness^[1] — Last year, Samsung introduced Vascular Load to help users monitor vascular stress and adopt a more holistic approach to health. Today, that vision evolves into the Heart Health Score. This single daily metric takes the insights previously found in Vascular Load — such as sleep, stress and activity — and combines them with body composition data. The result is a unified score that clearly identifies the habits impacting users’ long-term well-being, giving them immediate clarity on their heart health.

• Daily Cardio Load: Smarter Cardiovascular Training — When users are deciding how hard to push during aerobic exercise, Daily Cardio Load measures accumulated cardiovascular strain. By calculating daily load and maximum training capacity, it recommends optimal training targets and rest times to ensure users reach their goals without risking burnout or injury.

• Fitness Index: Seamless Progress Tracking — The Fitness Index ensures exercise routines are working by analysing metrics like heart rate, VO2 max (a key measure of aerobic fitness) and daily steps against users’ peers. By clearly identifying individual physical strengths and weaknesses, it delivers tailored content and personalised goals so users can make continuous, targeted improvements.

New Samsung Health Design for a Simplified, Personal Experience

To make these proactive insights easy to find, Samsung Health introduces a streamlined layout organised into five core pillars: Sleep, Activity, Nutrition, Mindfulness and Vitals. Within the Home screen, users can now easily access their daily wellness tips alongside their AI-powered Energy Score. This centralised view removes guesswork from health management, allowing users to quickly understand how different aspects of their routine interconnect at a single glance.

Upgraded Capabilities for Proactive Wellness

Samsung Health is also significantly advancing the core features users already rely on, delivering deeper personalisation with greater precision. As users navigate their day, Antioxidant Index^[2] now provides an even clearer roadmap of their nutritional intake. With new trend charts and daily history logs, it visually connects users’ dietary choices to physical responses over time.

Behind the scenes, the AGEs index has been enhanced to quietly work in the background, capturing automatic overnight measurements to build a long-term picture of how lifestyle choices accumulate in users’ bodies. This helps users uncover health insights that truly matter for their well-being.

Comprehensive wellness extends to external environments, as well, with Samsung offering a brand-new Hearing Health feature that integrates seamlessly across the Galaxy ecosystem. By monitoring surrounding ambient noise through Galaxy Watch, it delivers personalised analytics to help protect the user’s ears — whether they are on a loud commute or dialing up the music during a workout.

Together, these advanced refinements and new ecosystem-connected features turn everyday data into simple, practical guidance, setting the perfect stage for the future of Samsung Health.

A Seamlessly Connected Health Ecosystem

Samsung’s expansive ecosystem unlocks the true power of these new features, seamlessly managing health across users’ Galaxy mobile phones and connected devices. This frictionless integration ensures that personalised insights are always accessible, providing a unified view of user well-being.

These advancements offer a glimpse into the future of Samsung Health — a future that will be fully realised with the launch of Samsung’s next generation of Galaxy Watches, engineered to bring this proactive intelligence to life like never before.

As GLP-1 medications become widely adopted for weight management and chronic disease treatment, tracking changes in muscle mass and physical activity alongside weight loss has emerged as a key medical focus. This research will delve into the feasibility of managing muscle loss for GLP-1 patients by utilising biometric data including body composition, activity levels and heart rate provided by Galaxy Watch and Samsung Health.

Samsung and MGH have continuously collaborated on digital health research utilising both Galaxy Watch and Samsung Health, including studies on Advanced Glycation End Products (AGEs). The MGH Diabetes Research Center, which specialises in research on diabetes and GLP-1 obesity treatment, initiated the joint study with Samsung after recognising the potential for wearables to monitor body composition.

This study will also utilise Galaxy Watch8, powered by Samsung’s groundbreaking BioActive Sensor,^[2] which helps provide advanced predictive and preventative wellness through more accurate health measurements.

Under the leadership of Dr. Melissa Putman, the study will enroll 100 adults beginning treatment with weight-loss medications into two groups. The intervention group will use Galaxy Watch to monitor their body composition via Bioelectrical Impedance Analysis (BIA), track physical activity and receive personalised exercise guides. Their progress will be compared to the other group, which will receive the standard guidance and care typically given to patients starting GLP-1RA therapy.

To evaluate the study’s progress, researchers will use clinical-grade DXA scans^[3] — the gold standard for body composition analysis — to track physiological changes in both groups. These data will help determine whether the insights and tailored guidance provided by Galaxy Watch8 can effectively support participants in building healthier daily habits, which may in turn contribute to better health outcomes particularly in preserving muscle mass.

“Many GLP-1 patients struggle with muscle mass loss, a common side effect that can cause an increased risk of cardiovascular disease and a drop in basal metabolic rate, which can lead to future weight regain,” said Dr. Putman, Director of the MGH Diabetes Research Center. “We’re interested in exploring how continuous data from a wearable device can provide invaluable insights into a patient’s activity levels, heart rate and body composition, giving clinicians a more holistic view of treatment impact and allowing for more timely, data-driven adjustments to their care plan.”

“This collaboration with MGH focuses on addressing real-world health challenges that patients face during GLP-1RA therapy, specifically managing muscle loss and building healthy habits,” said Jongmin Choi, Head of Health R&D Group, Mobile eXperience (MX) Business, Samsung Electronics. “Ultimately, this study highlights Samsung’s ongoing commitment to delivering comprehensive and proactive health management solutions through the advanced capabilities of Galaxy Watch.”

Samsung remains committed to researching how Galaxy Watch can support patients in managing their daily physical health. By fostering sustainable wellness habits, the company aims to help patients achieve better clinical outcomes and long-term vitality.

Samsung continues to expand its partnerships with leading medical institutions to advance wearable health monitoring capabilities and broaden the digital health ecosystem. Recently, Samsung demonstrated the potential for early vasovagal syncope (VVS) detection using Galaxy Watch in a joint clinical study with Chung-Ang University Gwangmyeong Hospital in Korea, and also collaborated with Stanford Medicine to further advance Galaxy Watch’s Sleep Apnoea feature.

[1] Glucagon-Like Peptide-1 (GLP-1) is a hormone secreted by the intestines after eating that regulates blood sugar levels and suppresses appetite. While GLP-1 weight-loss medications that mimic this hormone are gaining significant popularity globally, they can be accompanied by side effects such as gastrointestinal disorders, muscle mass loss, and potential weight regain upon discontinuation.

[2] The BioActive Sensor is a technology that integrates three sensors into a single chipset: an optical heart rate sensor (PPG), an electrical heart rate sensor (ECG), and a bioelectrical impedance analysis sensor (BIA). This sensor has been featured in Galaxy Watch devices since the release of Galaxy Watch4 in 2021, allowing users to measure and monitor various health indicators, such as body composition, heart rate, blood pressure, and ECG tracking.

[3] DXA (Dual-Energy X-ray Absorptiometry) scan: A specialized medical imaging technology that uses low-dose X-rays to precisely measure body composition, including body fat, lean muscle mass, and bone density. Universally recognized as the “gold standard” for body composition analysis, it is widely utilized in clinical research to accurately evaluate physiological changes.

Vasovagal syncope occurs when a person’s heart rate and blood pressure drop abruptly due to factors like excessive stress, leading to a temporary loss of consciousness. While the fainting spell itself is typically not life-threatening, sudden falls can cause severe secondary injuries like fractures or concussions, making early prediction critically important for prevention.

“Up to 40% of people experience vasovagal syncope over their lifetime, with one-third experiencing recurrent episodes,” said Professor Junhwan Cho of the Department of Cardiology at Chung-Ang University Gwangmyeong Hospital. “An early warning could give patients advance time to get into a safe position or call for help, which would dramatically reduce the incidence of secondary injuries.”

The joint research team, led by Professor Cho, conducted evaluations on 132 patients with suspected VVS symptoms during induced fainting tests. Using a Galaxy Watch equipped with a photoplethysmography (PPG) sensor, the team analysed the watch’s heart rate variability (HRV) data with an AI algorithm. The model successfully predicted impending fainting episodes up to five minutes in advance with 84.6 percent accuracy, at a clinically meaningful sensitivity of 90 percent and a specificity of 64 percent.

“This study is an example of how wearable technology can help shift healthcare from being designed for ‘post-care’ to a model of ‘preventive care,’” said Jongmin Choi, Head of Health R&D Group, Mobile eXperience (MX) Business, Samsung Electronics. “We are committed to driving technological innovation that empowers our users to lead healthier everyday lives.”

The research findings were published in Volume 7, Issue 4 of “European Heart Journal – Digital Health,” a leading medical journal, and they represent the world’s first study to successfully demonstrate the potential for a commercial smartwatch to provide early prediction of syncope.

Samsung plans to further advance the health monitoring capabilities of its wearable portfolio and expand collaboration with leading medical institutions. Through these efforts, the company aims to lead the digital health industry and accelerate the implementation of personalised, preventive health solutions.

To mark World Sleep Day 2026, a global study of Samsung Health users^[2] is shedding new light on the true extent of the condition and the disruptive impact it has on your sleep. Aligned with this year’s World Sleep Day theme, “Sleep Well, Live Better,” Samsung is turning the invisible signs of sleep apnoea into actionable insights through its Galaxy Watch series, helping those affected improve their sleep habits and overall health.

Infographic including all key data on impact of sleep apnoea

How Does Sleep Apnoea Impact Your Sleep?

The report found that 23% of study participants are at risk of sleep apnoea.

“The microarousals and awakenings that follow breathing pauses fragment your sleep,” explains behavioural sleep scientist Dr. Vanessa Hill. “Those occurrences can prevent the brain from staying in the REM and deep sleep stages necessary for cognitive and physical restoration.”

The report shows these constant disruptions take a direct toll on sleep duration and quality, leading to:

• Reduced REM Sleep: Participants with moderate to severe sleep apnoea indicators detected by their Galaxy Watch got around four minutes less rapid eye movement (REM) sleep, the phase where our brains process emotions, consolidate memories and cement learning. Without enough of it, people can experience mood instability and memory problems, impacting performance at work and overall well-being.
• Less Deep Sleep: Sleep apnoea also robs sufferers of deep sleep, approximately eight minutes less per night, on average. This is the body’s critical physical restoration phase, where growth hormone is released, muscles are repaired, and your immune system is activated. Losing out on deep sleep is why you may feel physically exhausted, have slower recovery times, and get sick more often.
• Frequent Nightly Awakenings: Study participants with signs of sleep apnoea also woke up regularly during the night and stayed awake around four minutes longer. These interruptions derail the sleep cycle, locking you into lighter, less restorative stages and making next-day exhaustion inevitable, no matter how long you slept.
• Shorter Sleep Duration: Overall, people with a higher likelihood of sleep apnoea averaged around 12 minutes less sleep. While this loss may seem minor, it can have a significant impact on overall sleep quality as your sleep cycle gets fragmented throughout the night.

Why It Matters:

“Even a small loss in sleep duration is compounded by a larger loss of sleep quality,” said Dr. Hill. “This can be the difference between simply being ‘in bed’ and getting restorative rest, which could be why people feel so tired the next day.”

Dr. Hill also advocates a multidimensional approach to sleep health. “Sleep apnoea affects many dimensions of sleep — duration, quality, sleep efficiency and even daytime fatigue,” she stated. “They together help determine our health and functioning.”

With sleep apnoea shown to impact all aspects of sleep and lead to other health complications, detection is an essential first step in the fight against the condition.

How Does Galaxy Watch Help Detect Signs of Moderate to Severe Sleep Apnoea?

For years, sleep apnoea has been difficult to detect due to the need for inconvenient hospital tests. However, Samsung offers at-home detection with a first-of-its-kind^[3] feature on your Galaxy Watch.

• How It Works: Users simply track their sleep with a compatible Galaxy Watch^[4] for more than four hours over two nights within a ten-day period. Available through the Samsung Health Monitor app^[5], the Sleep Apnoea feature enables users to proactively spot signs of the condition. Initially launched in Korea, the feature has since received De Novo authorisation from the U.S. FDA and is now available in 78 markets worldwide, including the UK, and counting.
• The Technology: Leveraging the Galaxy Watch’s BioActive Sensor, the feature tracks blood oxygen levels to determine when the user stops breathing (apnoea) or is not breathing enough (hypopnea). Based on this data, the feature estimates the user’s Apnoea-Hypopnea Index (AHI), which indicates the severity of obstructive sleep apnoea (OSA).
• From Awareness to Action: By detecting signs of sleep apnoea early, the feature provides the data needed for an informed consultation with a medical professional. In addition to tackling sleep apnoea, your Galaxy Watch can help you build habits for better holistic sleep health. Features include the Sleep Coaching program for detailed analysis and tips on how to improve sleep quality and Bedtime Guidance,^[6] which recommends your optimal bedtime to ensure you consistently get enough sleep.

“For years, the inconvenience of an in-lab clinical sleep study has been a barrier to diagnosing sleep apnoea,” added Dr. Hill. “Wearable technology such as Galaxy Watch is a breakthrough because it democratises that first step. It allows people to gather meaningful data from their own beds, providing a starting point for a conversation with a healthcare professional.”

Take Control of Your Night

A good night’s sleep is the first step toward a healthier, more energised life, and Samsung is here to guide you. Samsung’s ecosystem offers end-to-end care, from detecting signs of sleep apnoea on your Galaxy Watch to providing suggestions to receive professional adviceto connecting you with professional advice through our health network.

Looking ahead, Samsung is constantly innovating and improving the Sleep Apnoea feature to make it even more powerful with sharper insights. Prioritise your rest today to unlock a healthier tomorrow.

Samsung’s Antioxidant Index^[1] on Galaxy Watch8^[2] transforms what once seemed like science fiction into everyday technology. In five seconds, a thumb scan returns precise carotenoid levels – the industry’s first measurable nutrition index.

By miniaturising lab-grade sensor technology with exceptional accuracy, it turns your diet into an actionable metric for healthier ageing. Establishing this new benchmark in wearable health tracking required years of intensive R&D, countless prototypes and unwavering grit.

Breaking New Ground in Nutrition Tracking

Back in 2018, Samsung saw a critical gap in wearables: we could count every step and calorie, yet there was no simple way to measure how our diet impacted our health. Deeper nutritional insights were locked behind expensive and time-consuming lab tests, out of reach for many people.

As people live longer, the focus is shifting from simply increasing lifespan to improving the quality of those additional years.

“In this context, antioxidation naturally gains attention as a method to slow down ageing,” explains Dr. Hyojee Joung, a Seoul National University^[3] who guided parts of the tech’s development. “If antioxidant management is neglected, Reactive Oxygen Species (ROS) accumulate in the body, increasing the risk of chronic diseases such as cardiovascular disease, diabetes and cancer.”

This realisation made antioxidants the cornerstone of Samsung’s mission. Engineers and scientists focused on carotenoids – key antioxidants and proven indicators of fruit and vegetable intake – to create a device small enough to sit on your wrist, yet powerful enough to turn complex antioxidant data into simple, actionable health insights for everyone.

The first prototype of the spectroscopy-based antioxidant sensor

Challenge #1: How to Shrink the Lab-Grade Sensor Technology

From day one, the dream of a nutrition-tracking wearable hit an immediate snag: traditional methods for measuring carotenoid levels like Raman spectroscopy are laser-based, non-invasive and precise, but rely on bulky machines that are far from wearable. So the team’s first mission was to shrink the lab-grade tech into a coin-sized sensor.

After seven years of rigorous testing and optimising since the first prototype, the team developed miniaturized sensor, a groundbreaking tech that combines multi-wavelength LEDs with a custom photodetector array to provide accurate carotenoid readings in a compact design.

“Our breakthrough was integrating reflectance spectroscopy with LEDs, which allowed us to miniaturize the technology while maintaining a high level of accuracy,” explains Jinyoung Park, a developer from Digital Health team at Samsung Electronics.

Antioxidant sensor LED-PD sensor modules

Unlike lasers, which emit a sharp, narrow wavelength, LEDs emit a broader wavelength range. By analysing how much light is absorbed by the skin at multiple wavelengths through photodiodes,^[4] the watch estimates carotenoid levels with impressive accuracy. The advanced algorithms that continuously calibrate in real-time also support precision while delivering personalised insights to each user.

The LED-PD Watch prototype testbed

Challenge #2: How to Ensure the Tech Reaches Everyone

Creating a coin-sized carotenoid sensor was a major milestone, but the next challenge was ensuring it could work accurately and reliably across diverse skin types, making it truly accessible to everyone.

To overcome challenges like melanin interference in darker skin tones, Samsung’s engineers opted to use the fingertip for measurements since it has the least melanin across all ethnic groups. They also added simple tweaks, like light fingertip pressure during scans, which helps temporarily reduce blood flow and hemoglobin interference, making the results more accurate.

Extensive trials conducted at Samsung Medical Center,^[5] included hundreds of participants, validating the sensor’s performance. This paved the way for a feature that seamlessly transitioned from the lab to users worldwide, offering an inclusive solution designed for everyday life.

How It Works

Carotenoids are the natural red, yellow, and green pigments found in fruits and vegetables. Since our bodies can’t produce carotenoids on their own, the levels stored in the body offer a clear snapshot of how much fruit and vegetables someone has been eating.

This is where your Antioxidant Index score comes in, reflecting your carotenoid levels based on these categories:

• Very low: Less than 50% of the daily WHO recommendation of 400g per day.
• Low: Between 50%–100%.
• Optimal: 100% or more.

“Skin carotenoids metabolise and accumulate in tissues gradually, so short-term changes in fruit and vegetable intake won’t immediately appear in the score,” explains Dr. Hyojee Joung. “Our research shows that increased carotenoid intake leads to a meaningful rise in skin carotenoid levels after about one to two weeks, making the Index a valuable tool for tracking consistent, long-term dietary habits.”

Lifestyle factors like sleep quality, stress levels, and physical activity also influence the Index, making it a well-rounded indicator of overall health. Paired with other Galaxy Watch8 features like sleep coaching, activity tracking and Vascular Load monitoring, the Antioxidant Index offers a holistic view of your well-being, empowering smarter decisions for healthier ageing.

The Antioxidant index feature measures carotenoid levels in seconds with the sensor on the back of the Galaxy Watch8 and provides additional nutritional insights on paired Galaxy smartphones.

Your Health, Reimagined

“New wearable sensors can play a role in helping people build healthy eating habits by tracking and encouraging sufficient daily intake of fruits and vegetables,” says Professor Yoonho Choi from Samsung Medical Center. “Over time, this simple practice can help support long term health and reduce the risk of age-related diseases, making it a very effective way to support overall wellbeing.”

Antioxidants are an emerging area of focus, but research has been limited due to the challenges of accurate measurement. Galaxy Watch8’s Antioxidant Index goes beyond current industry developments and delivers meaningful innovation.

Samsung’s ability to measure antioxidant levels with precision, acknowledged by experts as a benchmark for future research, represents a breakthrough in health monitoring. By helping users identify risks early and take proactive steps towards better health, Samsung is paving the way for a smarter, more proactive approach to wellness and redefining the role of wearables in preventative healthcare.

I’ve spent years witnessing technology change the way people live their lives. The way we work, connect and make decisions is entirely different from a generation ago; but until recently, eating routines, movement, and rest have largely been unchanged.

Technology today, in particular the rise of wearables, is now helping us also become aware of our health and track many elements of it. Everything from when to sleep and exercise and even what to eat. We’re at the dawn of truly predictive, personalised health intelligence.

This seismic shift is where every mouthful of food, every step taken, every wink of sleep is not just a mundane choice, but an act of self-care. Where technology moves from passive companion to active guardian – anticipating our needs and nudging us towards our goals.

What’s more, younger generations are running away from unhealthy choices. Recent data suggests run clubs have seen a 59% increase in global participation in 2024^[1], with people making friendships, and one in five of them resulting in a date. Health technology is not a passing fad or trend but something that is accelerating every day and making a real difference to people’s well-being.

This week, at the Cannes Lions International Festival of Creativity, we announced new Samsung Health features^[2] to help improve sleep, heart health, fitness, and nutrition. These new features are designed to help empower our consumers to lead healthier lives through proactive care and holistic health management.

My colleague Dr. Hon Pak, Senior Vice President and Head of Digital Health Team, Mobile eXperience,  talks about how sleep is the cornerstone of our approach to health, as it influences physical and mental well-being, social relationships, and even work performance.

Picture waking up, like many of us do, and checking your watch or ring. Instead of telling you how you slept, it guides your next choices by telling you “here’s why you slept well, and here’s what to do next”, or flagging any potential sleep issues.

The next frontier is preventative health, where technology doesn’t just monitor our wellbeing, it helps shape it. It’s happening all around us now, thanks to a seismic cultural shift which at Samsung, we are adapting to quickly.

A groundbreaking new Galaxy Watch feature we announced this week will measure vascular load^[3], the amount of stress on your vascular system while sleeping. The vascular system carries blood throughout the body to deliver oxygen and nutrients and remove waste, making it a strong indicator to determine good heart health.

I also spoke this week about our new Antioxidant Index^[4] – an industry first feature to measure carotenoids. Antioxidants are the nutrients found in many healthy foods, which help prevent chronic illnesses and promote healthy ageing. Importantly, antioxidants neutralise free radicals, which damage cells and accelerate aging. Behavioural factors, such as drinking alcohol, smoking, UV exposure, stress and lack of sleep, can accelerate aging by increasing free radicals in the body.

You will be able to use your Galaxy Watch and its advanced, light-activated BioActive sensor to measure carotenoids in just five seconds, which are antioxidants found in green and orange vegetables and fruits, stored in your skin.

You’ll quickly see how these insights reflect behavioural changes. For example, drinking carrot juice can show changes in the index. This transforms abstract nutrition into measurable outcomes that drive sustained healthy behaviours.

So, as we look ahead to the future of health tech, one thing is becoming undeniably clear: health will become the filter through which we make every choice. Not just the big decisions, like how we treat illness or manage fitness, but the small, everyday ones. What we watch. What we eat. What we buy. Because soon, the data will be right there with us, moment by moment, guiding us toward what our bodies and minds actually need.

And in that world, brands will have a new kind of responsibility. It won’t be enough to be relevant by trend or preference. Brands will need to prove their role in supporting people’s well-being—in showing how they truly fit into a better, healthier life.

That’s where we’re headed. We will continue to be more intentional with our health tech innovation. It will be deeply human focused, rooted in biology, mood, need, and real-time context.

At Samsung, we’re not just creating products that cut through the noise. We’re creating technology that cares. Because in the end, the greatest innovation isn’t in what we build, but in how we help people truly thrive.

What’s New 

• New features^[1] include Bedtime Guidance^[2], to help you optimise your sleep; Vascular Load^[3], which measures stress on your vascular system while sleeping; Running Coach^[4], to help strategise your training; and Antioxidant Index^[5], to measure your carotenoids for healthy aging.

• The new features are part of the One UI 8 Watch, which will be available on the newest Galaxy Watch series.  

Why it Matters:   

The goal of these new features is to help you build healthier daily habits, which can be challenging because they don’t develop instantly. It takes time to accumulate these behaviour patterns, and meaningful changes are often only apparent after a long period. But the rewards are worth it. 

• For example, eating unhealthy food may not immediately impact your health, but over time, it can have significant consequences.  

• Conversely, adopting healthy habits may not show immediate results, but over time, they lead to positive changes in your body and mind. 

• Samsung Health’s new features aim to help you develop healthy habits by motivating you through instant feedback on your health. These features inspire you to maintain your habits by providing rewards or warning signs and demonstrating immediate impact of your behaviours.   

“Sleep remains a cornerstone of our approach to health, as it influences physical and mental well-being, social relationships and even work performance,” said Dr. Hon Pak, Senior Vice President and Head of Digital Health Team, Mobile eXperience, Samsung Electronics. “Now, we envision our Galaxy Watch delivering holistic insights centred around sleep—insights that lead to meaningful changes in daily life. We believe this aligns with our vision of empowering you to lead healthier lives through proactive care and holistic health management.” 

Explore New Health Features 

Samsung Health’s new features aim to help users develop healthy habits, using instant health feedback as a motivating tool. 

Bedtime Guidance  

A single night of restful sleep offers immediate health benefits, encouraging more proactive behavior changes and leading to a healthier tomorrow. This starts with a regular and optimal bedtime. 

• We constantly seek to advance our sleep-related tools, which include sleep pattern analysis, sleep coaching, and optimising sleep environments.  

• Now, we are providing additional tools to help you get  better sleep by suggesting an optimal bedtime based on your lifestyle and sleep patterns while sending reminders to help you stick to it.   

• By analysing your past three days’ sleep patterns, the feature evaluates your need for sleep pressure and your circadian rhythm to calculate a bedtime that maximises alertness the next day. 

• This feature is particularly helpful for those trying to optimise their sleep after periods of irregular bedtimes. For example, if you go to bed later than planned over several days, or have inconsistent sleep schedules between weekdays and weekends, the bedtime guidance will consider these factors to ensure you get enough sleep. 

Vascular Load   

Sleep is a window into overall health, as it impacts holistic well-being. Galaxy Watch uses this opportunity to measure vascular load—the amount of stress on your vascular system while sleeping.   

• The vascular system carries blood throughout the body to deliver oxygen and nutrients and remove waste, making it a strong indicator to determine good heart health.   

• During sleep, stress on your vascular system should naturally dip; however, excessive fluctuations can negatively impact cardiovascular health. 

• Simply wear your Watch while sleeping, and it will measure your vascular load, providing insights into the stress on your vascular system^[6]

• Additionally, since all health factors are interconnected, the feature also provides insights into lifestyle factors such as sleep, exercise, and stress to help you maintain a healthier lifestyle and develop positive habits. 

Running Coach   

While sleep is a precious time to cultivate and care for your health, managing your health during active moments is equally important. Running is one of the most basic and universally available fitness activities, and Samsung has long sought to support runners, offering features to help everyone stay active and achieve their fitness goals.   

• Many runners face injuries due to over-pacing or are not optimally pushing themselves. Running Coach is designed to help runners safely complete marathons through optimised-intensity and injury-preventive training, making it ideal for beginners. 

• Our new Running Coach feature delivers motivation and real-time guidance, creating a unique training program based on your fitness level to help you achieve your goals. 

• Just wear your watch and run for 12 minutes; it will analyse your performance and running level from 1-10. You’ll receive a detailed training plan to help you complete a 5K, 10K, half marathon, or full marathon based on your level. Complete your training session, and you’ll level up and unlock your next running challenge. 

Antioxidant Index   

When taking a holistic approach to health, we naturally focus on ageing and inspiring healthy ageing.   

However, behavioural factors, such as drinking alcohol, smoking, UV exposure, stress and lack of sleep, can accelerate aging by increasing free radicals in the body. These free radicals damage cells and accelerate aging. Antioxidants, nutrients found in many healthy foods, are molecules that neutralise these free radicals, helping prevent chronic illnesses and promote healthy ageing.   

• Use Galaxy Watch to measure carotenoids, which are antioxidants found in green and orange vegetables and fruits, stored in your skin.   

• Galaxy Watch employs an industry-first feature to measure carotenoids in just five seconds via its advanced, light-activated BioActive sensor.  

• These insights reflect behavioural changes. For example, drinking carrot juice can show changes in the index—providing motivation to adopt healthier habits. 

Great health comes from the combination of many small changes—and with Galaxy Watch, it is now possible overnight.
