Biohacking is about turning personal health data into micro-upgrades that boost wellness and longevity. Early biohackers might have chased these gains with extreme diets, supplements and experimental techniques. But if you scroll your social feed today, tech leads the conversation.

At the forefront of this tech-driven movement is the Galaxy Watch8 series ^[1]. Seamlessly integrating into your daily routine, it quietly tracks key lifestyle metrics so you can see how the choices you make throughout the day impact your health.

Before we dive in, let’s do a quick check-in: how many of these biohacks are already part of your routine?

Already acing your biohacks? The Galaxy Watch8 series help you refine each habit for faster, smarter gains.

Optimise Your Sleep with Biohacking

We spend about 30% of our lives asleep, yet irregular schedules and sub-optimal environments still undermine rest. The Galaxy Watch8 series helps you optimise your sleep by analysing your sleep patterns and environment, identifying issues, and giving actionable tips to help build consistent, restorative sleep habits.

• How can I follow a regular sleep schedule?

Wear Galaxy Watch8 for three nights to unlock Bedtime Guidance^[2]. It analyses your sleep patterns, recommending the best times to wind down, based on your sleep pressure and circadian rhythm, helping you reset your sleep schedule and maximise alertness during the day.

• How can I improve my sleep quality?

Galaxy Watch8 tracks every toss, turn and breath of your night. Each morning you get an in-depth sleep analysis based on your sleep stages, heart rate, skin temperature and oxygen level, highlighting what helped or hindered your rest.

You can also access a Sleep Environment Report which leverages data from your other SmartThings devices to analyse temperature, humidity, CO2 and illuminance. With this data at your fingertips, you can easily optimise your room conditions for a better night’s sleep.   

• What can I do during the day to improve my sleep?

Once your sleep patterns are defined, Sleep Coaching assigns you a Sleep Animal and delivers personalised tips like adding a quick meditation session or skipping late-day caffeine. With Galaxy Watch8, small, daily habit upgrades are easy, and better nights are within reach.

Optimise Your Workouts with Biohacking

Some people train for marathons. Others just want to feel less stiff after sitting all day. So how do you reach your goals while staying motivated? The Galaxy Watch8 series gives you all the answers, all while sitting snugly on your wrist thanks to its sleek design and dynamic lug system.

• How do I set the ideal fitness goal for me?

Galaxy Watch8’s built-in Bioelectrical Impedance Analysis (BIA) sensor measures your body fat percentage, body-water content and skeletal muscle mass, so you get a comprehensive snapshot of your body. These insights help you create a personalised training plan and track every step of your progress.

• How can I start running more consistently?

Start with Running Coach ^[3], which analyses your pace and fitness level after just a 12-minute run to build a custom routine. It also keeps you motivated during your runs with real-time feedback, helping you to reach your goals. Worried about potential injury from doing too much too soon? Running Coach provides tailored training programs at the ideal intensity, helping you gain speed safely.

• How can I maximise recovery after training?

Samsung Health gives you the tools for optimal post-workout recovery. Check your heart rate after an intense workout and get recommendations on water intake based on sweat loss, so you can get the rest you need to come back stronger.

[Bonus Tip] Try Zone 2 ^[4] interval training, known to improve endurance and boost fat burning potential. Galaxy Watch8 sets personalised Heart Rate Zones based on your fitness level to help you stay within your personal HR Zone 2 for peak results.

Optimise Your Nutrition with Biohacking

Now that sleep and activity are under control, turn to the everyday habits that drive healthy ageing. The Galaxy Watch8 series is the first smartwatch to track antioxidant levels, giving you a real-time view of your cellular health and how each lifestyle choice shapes it. Just put your thumb on the back sensor to get Instant Nutritional Feedback that used to require lab tests.

• How do I know if I’m eating enough fruits and vegetables?

Use the Antioxidant Index ^[5] to see how your diet and lifestyle habits impact healthy ageing. Within just five seconds, it measures the carotenoids — natural antioxidants from fruits and veggies — stored in your skin and provides a score out of 100. It also offers tips to boost your score, like adding more colorful produce such as carrots, broccoli and oranges to your meals.

• How can I cut down on unhealthy habits?

First, we must learn more about how our bodies are affected by these unhealthy habits. Your Energy Score provides insights on how factors such as alcohol intake and late-night snacking affect your health, while Antioxidant Index directly shows the impact of these habits — motivating you to change your ways and adopt a healthier lifestyle.

• How can I easily track my water intake?

Proper hydration is essential for performing at your best, but it is often difficult to track. With Samsung Health, you can track your water intake with just a tap and set a daily hydration goal. Galaxy Watch8 will handle the rest by sending personalised reminders and monitoring trends, making it effortless to stay on top of your game.

The Galaxy Watch8 series turns biohacking from buzzword to habit — personal, actionable and effortless. Wear it, watch the insights roll in, and let better health become second nature.

In fact, more than 42% admit to making at least one ‘running red flag’ mistake, with many making the same early missteps: pushing through injury (32%), running too fast too soon (29%), or simply getting swept up in social media fuelled comparison (23%).

Red flags on the rise

These missteps aren’t just harmless habits however, they can lead to burnout, lost motivation or injury. Crucially, they get in the way of what more and more people are seeking from running as a hobby: mental clarity, community and a consistent wellbeing routine.

The most common mistakes include skipping warm-ups and cool-downs (42%), running solely to burn calories or lose weight (41%), and running through pain or ignoring injury signs (32%). Others admitted to buying expensive gear before building a habit (15%), or following rigid training plans that don’t fit real lives (18%).

Samsung’s new Galaxy Watch8 is designed to support a more balanced approach to fitness and wellness with features such as Running Coach[1]. Offering a tailored training program, real-time feedback and recovery insights, it helps runners stay consistent, motivated and injury-aware without overdoing it.

Running smarter not harder

According to Clinical Psychologist Dr Julie Smith, red flags are part of the process, but the key is knowing when to spot them and when to reset.

“Many people take up running to feel better mentally as well as physically — but it’s easy to fall into ‘all or nothing’ thinking,” says Clinical Psychologist Dr Julie Smith.

“They push themselves too hard, compare their progress to others, and when it doesn’t go perfectly, they give up. That mindset can take a real toll on both motivation and mental wellbeing. The Galaxy Watch8’s Running Coach helps people stay grounded with real-time support and structure, while also tracking key wellness indicators like sleep and heart rate variability, tools that empower runners to build sustainable habits that support both body and mind.”

A running revolution in the making

When it comes to what gets people lacing up their trainers, personal connections lead the way, with 37% saying they were inspired by a friend or family member’s transformation. Local running clubs and park runs (26%) are also powerful motivators, while social media continues to play a role, with 23% crediting running influencers on platforms like Instagram and TikTok for sparking their interest.

The research also found that mental wellbeing is now one of the top reasons that people start running. Over 52% of runners surveyed said they lace up primarily to improve their mood and 48% to reduce stress, rather than to hit traditional fitness goals, whilst 43% said they were looking for a sense of accomplishment or routine.

When running becomes a habit, the benefits are wide-reaching. Respondents said that running helped them to sleep better (51%), improve cardiovascular fitness (49%) and boost energy and focus during the day (42%).

Samsung Electronics Co., Ltd. today introduced Galaxy Watch8 and Galaxy Watch8 Classic^[1], establishing an iconic design identity across the entire Galaxy Watch lineup.

Building upon the foundation of the Galaxy Watch Ultra’s cushion design, this series boasts the thinnest, most comfortable Galaxy Watch ever^[2] for continuous health tracking. The Galaxy Watch8 series suits diverse lifestyles and provides advanced capabilities, setting a new standard for style and personalised health experiences.

“The next frontier for wearable technology is preventative health. We don’t want to just monitor peoples’ wellbeing – we want to give them personal, reliable and meaningful insights,” said Annika Bizon, Mobile Experience VP of Product and Marketing, Samsung UK & Ireland. “The Galaxy Watch8 series sets a new standard by combining comfort, form and function with advanced sensor technology that is powered by AI, helping everyone build longer-term habits where every decision we make will be guided by our health.”

Redesigned Inside and Out for Ultimate Wellness

By reimagining both form and function, the Galaxy Watch8 series delivers unmatched comfort alongside industry-leading performance, making it the ultimate companion for everyday wellness. The distinctive cushion design, which debuted with Galaxy Watch Ultra, now defines the entire Galaxy Watch lineup.

To achieve the thinnest design yet, the internal structure of Galaxy Watch8 was completely reengineered and its component mounting capability has been improved by 30%, resulting in an 11% thinner design. Combined with the Dynamic Lug system, this design moves naturally with the wrist, providing greater comfort and improved stability^[2] for a better fit and enhanced health-tracking accuracy.

Galaxy Watch8’s sleek profile is complemented by its exceptional performance. Even when you are outdoors under bright sunlight, the display is 50% brighter^[2] with a peak brightness of 3,000nits for easy visibility, and the enhanced battery^[2] ensures the watch can keep up with an active lifestyle.

Moreover, the dual-frequency GPS provides more detailed and precise location results^[2] while our most powerful 3nm processor delivers faster performance and greater power efficiency. With the groundbreaking BioActive Sensor that enables deeper and more accurate health insights, the Galaxy Watch8 series helps provide a holistic view of your health.

Motivation for Lasting Health Changes

Sleep is a window into your overall health and each restful night allows your body and mind to recover immediately the very next day. That’s why Samsung is continuously advancing the sleep experience, offering tailored sleep coaching, helping to create an optimal sleep environment, and even detecting moderate to severe signs of sleep apnoea^[3]. On top of that, the Galaxy Watch8 series comes with new unique health features on the Samsung Health app^[4] that help you build healthier habits through instant, motivational insights – from sleep to nutrition and workout.

Bedtime Guidance^[5] can measure your circadian rhythm to suggest the optimal time to go to bed so you wake up refreshed the next morning. Vascular Load^[6]helps monitor the stress levels on your vascular system during sleep. Providing insights on various lifestyle factors including sleep, stress and activity, it helps you adopt a more comprehensive approach to managing your health.

Meanwhile, the Galaxy Watch8 series introduces Antioxidant Index^[7]for the first time in a smartwatch, enabling you to measure carotenoid levels in just five seconds and make informed lifestyle choices for healthy aging.

Whether you’re a novice or experienced runner, the Galaxy Watch8 series delivers personalised fitness insights to keep you motivated when you need it most. Running Coach^[8] calculates your fitness level from 1 to 10 and develops a tailored training plan complete with real-time guidance and motivational insights. With the updated Together feature, which now supports running, you can gamify your fitness journey by challenging friends and family.

If high level of stress persists, High Stress Alert will immediately signal so that you can take a break to help manage your stress levels in real-time. With Mindfulness and Stress Tracker^[9]you can record your mood and receive guidance on breathing exercises to relieve your stress – all at once on your wrist.

Plus, the AI-powered Energy Score^[10]gives you a snapshot of your energy level, combining physical and mental energy metrics so you can have a healthier day, every day.

Easier Watch Interaction with Wear OS and Gemini

Developed in close collaboration with Google, the Galaxy Watch8 series is the first smartwatch equipped with Wear OS 6 as well as Gemini^[11], Google’s AI assistant, as pre-loaded. Go hands-free using natural voice commands to get things done on the go with your Galaxy Watch apps like Samsung Health, Calendar, Reminder, and Clock. For example, you can ask Gemini to find a nearby cafe and text a friend to meet you there, all in one go. Or, if you’re ready to start your workout and you have a goal in mind, simply say, “Start a 30-minute run.” The watch seamlessly initiates the workout in Samsung Health.

In addition, thanks to the new One UI 8 Watch, the user interface is optimised for the size and shape of the watch face. The new Multi-Info Tiles provide easy access to health metrics, weather, events and more – all in a single, quick look. Moreover, the new Now Bar and depthless notifications ensure key activities are front and center.
