Sleep Coaching Becomes Easier to Start and More Personalised

While sleep tracking tells users how they slept, sleep coaching helps them sleep better by turning personal sleep goals and data into daily habits.

Samsung has made it even easier to begin sleep management. Users can now initiate Sleep Coaching with just three days of data within the past two weeks instead of seven days in a month.

During setup, users complete a survey on sleep regularity, sleep interruptions, alcohol and caffeine intake and subjective sleep satisfaction. With these survey responses and three days of sleep data, the app assigns a personalised Sleep Animal symbol and builds a tailored four- to eight-week coaching program based on individual goals. As users progress, the program dynamically adapts its weekly recommendations to reflect changing sleep patterns, tracking daily sleep satisfaction and lifestyle shifts.

Informed by principles of behavioral sleep science, the program gives users daily habit checklists and sleep tips — making it easier to build healthier routines, such as avoiding screens an hour before bed, skipping late caffeine and stretching outdoors after waking up.

Users can also enjoy more intuitive and detailed analysis reports. The new pentagon-shaped Sleep Balance graph consolidates five key aspects of sleep indicators —sleep time, sleep regularity, awake time during the night, sleep satisfaction, and Energy Score²— to provide an at-a-glance view of sleep trends and areas that may warrant attention, based on data collected or inputted through sleep coaching.

Morning daily insight messages, which review the previous night’s sleep with helpful tips, integrate closely with weekly and final reports to provide a comprehensive view of sleep trends. By linking daily actions with this data-driven progress, Samsung Health helps users establish sustainable lifestyle habits to support everyday wellness.

Expanded Running Programs and Strava Routes Integration

In response to the growing popularity of running, Running Coach³ has been upgraded to deliver a more dynamic and connected training experience.

Training tiers have expanded from 10 to 12 levels. While users continue to receive a personalised training plan based on a 12-minute running test or their historical running data, this update introduces new levels to support intermediate and advanced runners. These dedicated training tiers enable them to set higher benchmarks, challenge themselves, and steadily improve their performance.

To celebrate achievements and sustain motivation, Running Coach introduces an enhanced social media sharing feature. Runners can seamlessly export their workout data into share-ready templates designed for various social platforms, making it easier to share milestones, personal records, and route highlights with their fitness communities.

Samsung continues to strengthen ecosystem connectivity through a partnership with Strava, a global fitness platform. Users can import their favorite Strava Routes for running, trail running, and cycling directly into Samsung Health. This integration supports compatibility and user convenience across both platforms. 

“Samsung Health’s personalized coaching empowers users to understand their health data, taking a step toward supporting everyday wellness,” said Hon Pak, Senior Vice President and Head of the Digital Health Team for the Mobile eXperience Business at Samsung Electronics. “We will continue to leverage the Galaxy ecosystem and our technology to build a trusted health platform.

These upgraded features will be progressively rolled out via Samsung Health app updates starting in October.

The training is nearly done, your kit is ready and the start line is approaching. But have you explored the features on your smartwatch that could support your final preparations?

Ahead of the Royal Parks Half Marathon, Samsung shares tips from UK Product Specialist Lee Dinham to help runners make more of their Galaxy Watch9 and Galaxy Watch Ultra2.

How can I keep an eye on my training and recovery?

Galaxy Watch’s Daily Cardio Load feature provides insights into your activity levels, helping you consider when to ease off¹. As race day approaches, use those insights alongside how you feel when planning your remaining sessions.

“I think we’re all guilty of not getting enough rest and recovery time,” says Lee.  “The Daily Cardio Load feature gives a great indication of if I’m doing too much – or not enough – and will give me a nudge to take it easy every so often.”

How can I understand my sleep before race day?

Lee also recommends exploring the broader health insights available on Galaxy Watch, including Sleep Score in Samsung Health².

During your final preparations, make time to review your sleep alongside your activity, rather than focusing solely on the miles you’ve covered.

How can I quickly access my favourite workout(s)?

One of Lee’s favourite hands-free shortcuts is Galaxy Watch’s “knock knock” gesture, which can launch an exercise or a favourite app.

His advice is to assign the gesture to a function you regularly use, so you can access it with a movement of your hand.

How can I get a quick answer when my hands are full?

With Raise to Talk, lift your Galaxy Watch towards your mouth to speak to Google Gemini³. Whether you want to check the weather before setting off or ask a last-minute question while carrying your race bag, you can get a quick answers on the go.

Lee names Raise to Talk as his favourite feature on Galaxy Watch9 and Galaxy Watch Ultra2, finding it useful for quick answers on the move, “especially without having to reach for my smartphone”.

Whether you’re taking on your first half marathon or returning for another race, spending a few minutes exploring your watch before the weekend can help you feel more familiar with the features you’ll use.

Heart disease is the number one cause of death worldwide¹, which is why the World Health Organization (WHO) and the World Heart Federation recognise Sept. 29 as World Heart Day. It is a reminder that the choices we make today can make a meaningful difference tomorrow.

These choices don’t have to be big. From choosing when to go to bed to making time for even just 30 minutes of exercise, the small choices we make every day add up to a healthier lifestyle.

The good news is that Samsung Galaxy Watch can help you make proactive prevention part of daily life. By monitoring your sleep, activity level, stress and blood pressure, Galaxy Watch helps you better understand what’s happening in your body and what steps to take to ensure your heart is doing its job well.

Understanding Your Body at a Glance: Heart Health Score

The American Heart Association recommends looking at Life’s Essential 8² as key measures for improving and maintaining cardiovascular health: diet, exercise, sleep, weight, blood pressure, blood sugar, cholesterol and smoking cessation. But knowing what matters raises an important question: how do these factors change the choices we make every day?

Samsung Health’s Heart Health Score³ is designed to help you in this journey. It tracks and analyses complex health indicators such as sleep duration, daily activity level, body composition and vascular load⁴, converting them into a single, simple score that anyone can intuitively understand and follow.

Think about what happens if you miss your daily exercise for a few days: your Galaxy Watch recognises your moderate-to-high intensity activity level has decreased, reflects this change in a lower Heart Health Score, and makes a recommendation to go for a run. With convenient insights right from your wrist, Galaxy Watch delivers personalised insights that make it easier to recognise changes, understand your habits, and take the next step toward healthier ones.

Samsung Galaxy Watches are equipped with an advanced BioActive Sensor which integrates three precision sensors in one: an optical heart rate sensor (PPG), an electrocardiogram sensor (ECG)⁵ and a bioelectrical impedance analysis sensor (BIA).

Advanced Sensor Technology: From Measurement to Meaning

With calibration just once every four weeks using a home blood pressure monitor, you can easily check your blood pressure⁶ from your wrist anytime, anywhere. When you place your finger on the watch’s side electrode for just 30 seconds, the watch measures an electrocardiogram to detect signs of abnormal heartbeats like atrial fibrillation or ectopic beats. The Irregular Heart Rhythm Notification (IHRN)⁷ feature, which detects abnormal heart signals, monitors the user’s heart rhythm throughout the day and provides a proactive notification if abnormal signs are repeated.

Even small reminders like this have the power to save lives. In several countries, these notifications⁸ have led to early detection of risks such as atherosclerosis or myocardial infarction.

Around-the-Clock Care: How Galaxy Watch Proactively Monitors Your Health Even During Sleep

Your heart is a constant you can count on, and it works whether you’re awake or asleep. When you wear your Galaxy Watch to sleep, it analyses five major vital signs: heart rate during sleep, heart rate variability⁹, respiratory rate, skin temperature and blood oxygen saturation. These signals are compared against your personal baseline.

When you wake up, your Galaxy Watch will send a notification if it detects meaningful deviations from your baseline. By highlighting meaningful changes early, it gives you an opportunity to rest, recover or seek medical guidance before small issues become larger concerns¹⁰.

Galaxy Watch and Samsung Health give users a clear view of their sleep quality with detailed metrics and insights they can use to improve their sleep habits.

Heart to Heart: Connected Care That Adds Peace of Mind

Looking after your own heart is only one side of the story. From parents to partners, siblings to grandparents or even friends, the burden of caring for the hearts of those around you weighs heavily. Samsung Health’s Health Data Sharing¹¹ function lightens the load by sharing agreed-upon data items (number of steps, blood pressure, heart rate, medication adherence, etc.) with loved ones in real time.

You can check if your parents who live far away have completed their daily walk or taken their prescribed medication on time, just as if you were right there with them.

World Heart Day coincides with the seasonal transition when chilly winds begin to blow in the mornings and evenings. As the temperature gap between day and night widens, blood vessels constrict, sharply increasing the risk of cardiovascular disease.

The key to preventing heart disease lies not in reactive treatment, but in proactive habits of paying close attention to the subtle signals your body sends every day. Start managing your heart health with Galaxy Watch, a reliable health partner that stays with you around the clock.

Brits have embraced a new era of optimisation, with people investing more time, money and energy into improving their health and performance – but new research suggests one of the most powerful performance tools is still being overlooked: recovery, with just 23% saying resting and recovering properly is something they prioritise when working towards a fitness goal.

From premium running shoes and protein powders to wearable technology and wellness subscriptions, the pursuit of peak performance has become big business, with Brits increasingly adopting the habits and tools once associated with professional athletes.

New research from Samsung for the Galaxy Watch Ultra2, found 82% say improving their physical health is a priority, while more than half (54%) hope to exercise more regularly over the next 12 months.

Yet despite this focus on optimisation, 48% agree rest and recovery are just as important as exercise, but 18% admit they find it difficult to prioritise, and just a quarter (25%) actively plan rest or recovery days into their routine.

In fact, more than half (55%) find the recovery process a hindrance, with 89% admitting they have pushed through tiredness to hit a fitness target or step count, rather than prioritising recovery.

The research reveals a growing ‘recovery gap’ between the effort people put into training and the attention they give to recovery. While Brits are increasingly adopting athlete-like approaches to performance, from tracking workouts to chasing personal bests, many are overlooking the role sleep, recovery and listening to their body play in helping them perform at their best.

And that imbalance could be making it harder to stay on track. Fitness goals fall by the wayside after an average of 33 days, while 37% have abandoned a fitness goal within 30 days of starting it.

But Brits recognise the potential benefits of understanding their bodies better. Seven in 10 (70%) agree that understanding how their body is responding to training and recovery would help them improve their fitness or performance, while 34% say personalised recovery insights would help them know when they need to rest and recover.

Experts say pushing harder isn’t always the answer. While exercise provides the stimulus for the body to adapt, it’s during recovery – through quality sleep, rest and allowing the body to repair – that those fitness gains are made.

Olympic medallist Max Whitlock, who has partnered with Samsung, says: “Recovery isn’t the reward for training, it’s part of the training. The sessions everyone sees are only possible because of everything that happens afterwards.

“Understanding when your body needs rest is just as important as knowing when to push.” 

For many Brits, knowing when to rest is still based largely on instinct. Adults are more likely to assess how their body is responding to exercise and recovery based on how they feel physically (53%) or their level of tiredness (40%), rather than taking a set approach (15%).

This comes as on 16% admit they only take a rest day if they feel sore, tired or run down.

Samsung’s Galaxy Watch Ultra2 helps users take a more informed approach to training and recovery through personalised health insights, helping them better understand how their body is responding to exercise, sleep and rest.

Annika Bizon, Mobile Experience VP of Product and Marketing, Samsung UK & Ireland, says: “More people are taking their fitness seriously and challenging themselves to achieve more, but our research shows there’s still a gap between how people train and how they recover. In many ways, we’re training like athletes but recovering like amateurs.

“People want to be better informed about their health and what their bodies are telling them, and this is where technology can play an important role. By turning personal health data into tailored, actionable insights, people can understand when they might be ready to push themselves and when they might need more rest.”

Energy Score on the Galaxy Watch Ultra2 brings together insights including sleep, activity and heart rate to provide a daily indication of physical and mental readiness, while Daily Cardio Load¹ helps users understand the impact their workouts are having on their body over time.

Alongside detailed sleep tracking and personalised fitness features, Galaxy Watches can help users take a more informed approach to both sides of the performance equation – knowing when to push and when recovery should take priority. 

Additional stats:

• 36% of Brits struggle to stay motivated when the initial excitement of setting their goal wears off
• 27% say having more time in their schedule would help them stay on track with their fitness goals
• 34% admit they find it difficult to fit exercise around everyday commitments

1. To use the features, at least 7 days of activity records are required, while 28 days of continuous wear is recommended for optimal accuracy. Please note that values may increase in daily situations where heart rate rises, such as during tension, anxiety or stress. ︎

At Galaxy Unpacked July 2026 in London on July 22, Dr. Hon Pak, Senior Vice President and Head of the Digital Health Team, Mobile eXperience (MX) Business at Samsung Electronics, sat down with cognitive neuroscientist and science communicator Dr. Dong-seon Chang to explore how AI could make health management simpler and more connected.

Dr. Pak explained how the body changes from day to day and how AI can learn an individual’s daily rhythms and patterns to help transform fragmented health data into more meaningful, personalised guidance. He also introduced Samsung Health’s Connected Care vision, extending beyond devices and data to connect people — from healthcare professionals and families to partners across the broader health ecosystem.

Ultimately, the conversation pointed to a broader question of how society can embrace AI while keeping people at the centre.

Watch the video below to learn more about Samsung’s vision for healthcare that is simpler, more connected, and human-centred.

The Health Forum held at Galaxy Unpacked July 2026 also shared Samsung’s Connected Care vision for the next chapter of digital health — a future where care moves from reactive treatment toward preventive, personalised and connected experiences, supported by trusted health innovation and partnerships across the healthcare ecosystem. One technology that is helping power these new consumer experiences is the health foundation model.

Researchers from the Digital Health Team at Samsung Research America (SRA) are developing new AI technologies to continuously understand a person’s health state from biosignals, generate health insights, and offer appropriate health guidance.

Samsung researchers recently introduced two foundation models based on wearable data: xMAE (Physiology-Aware Masked Cross-Modal Reconstruction for Biosignal Representation Learning), which learns the temporal relationship between different biosignals, and HiMAE (Hierarchical Masked Autoencoder), which understands health patterns across different time scales in wearable time-series data. Both studies demonstrate advancement of health AI models that can better understand the physiological relationships and temporal structure of biosignals.

Samsung’s work on xMAE and HiMAE models was accepted to the International Conference on Machine Learning (ICML), and the International Conference on Learning Representations (ICLR), respectively, highlighting the significance of this research.

Health Foundation Models That Read the Body’s Signals: Why They Matter for Health 

A health foundation model is an AI model that uses self-supervised learning to learn meaningful features from unlabelled biosignal data. After being pretrained on large-scale health data, the models can be applied to perform a wide range of downstream health tasks, including biosignal analysis, developing new or improved biomarkers, and health issue prediction.

xMAE AI model: Continuous Cardiac Insight from Wearables

An electrocardiogram (ECG) on wearables directly measures the electrical activity of the heart and is useful for measuring heart rate and heart rate variability, identifying abnormal heart rhythms and risks for conditions such as atrial fibrillation.

ECG is highly accurate, but typically requires users to pause and take an active measurement. On the other hand, photoplethysmography (PPG) can indirectly measure cardiac function by detecting changes in blood flow and can be passively and continuously measured through sensors in wearable devices such as smartwatches.

The two signals originate from the same cardiac activity, but they appear with a certain time difference, much like thunder is heard after lightning is seen. xMAE is a biosignal pretraining framework designed to learn the temporal relationship between the two signals by reconstructing masked portions of the ECG signal using the more easily and continuously measured PPG signal. As a result, cardiovascular health-related features can be analysed more precisely using PPG without requiring separate manual ECG measurements.

The researchers pretrained xMAE using approximately 9,400 hours of ECG and PPG data. The model outperformed unimodal biosignal models and existing multimodal learning methods in 15 of 19 evaluation tasks, including cardiovascular disease prediction, abnormal test-result detection, and sleep-stage classification. The study also confirmed the potential to use the learned features across different sensor devices, body locations and data-gathering environments.

HiMAE AI model: Reading the Body at Every Time Scale on the Device

Health data measured from wearable devices can reveal different information depending on the time scale at which it is analysed. For example, short time segments can reveal rapidly changing signals such as heartbeats, while longer time segments can uncover patterns that accumulate over time, such as sleep or physical activity. This is similar to examining different information by zooming in and out of an image.

HiMAE is a self-supervised learning model that learns representation from wearable data across multiple time scales. It uses multiple encoders to analyse short and long segments separately, allowing the model to identify information required for each health task, such as heart rate analysis or sleep prediction, at the appropriate time scale. During training, the model reconstructs masked parts of the data. This enables it to learn key patterns in biosignals even when labelled data is limited.

A single pretrained HiMAE model handles classification, numerical prediction and data generation. The model achieved high performance while being smaller than existing models. It also improved computational efficiency to the point where it can produce results in less than one millisecond on a smartwatch-class central processing unit (CPU). Most importantly, HiMAE demonstrates the potential of on-device health foundation models for the first time—analysing raw health signals in real time, without relying on cloud servers.

The Next Step Toward Connected Care

Together, xMAE and HiMAE, represent an advance in AI models that precisely understand the physiological relationships and temporal structures unique to biosignals. Both models aim to deliver precise, continuous, personalised health insights and to generalise across many health tasks from a single pre-trained model.

▲ 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.
