When it comes to health, small changes can make a big difference. Every incremental improvement to daily habits contribute to a healthier whole, and the upcoming One UI 8 Watch is designed to help build these habits more effectively through a suite of new features that support sleep, heart health, fitness and nutrition.
What’s New:
New features include Bedtime Guidance to optimize sleep; Vascular Load to measure stress on the vascular system during sleep; Running Coach to support personalized training strategies; and Antioxidant Index to measure carotenoid levels for healthy aging. These features — part of One UI 8 Watch on the latest Galaxy Watch series — will be available to a limited number of users through a beta program.
Why it Matters:
The goal of these new features is to help build healthier daily habits — which can be challenging as they don’t develop overnight. It takes time to form lasting behavior patterns, and meaningful change often becomes visible only after sustained effort. But the rewards are worth i
For example, while eating unhealthy food may not have an immediate impact, it can lead to significant health consequences over time. Conversely, healthy habits may not produce instant results, but they often contribute to long-term physical and mental well-being.
“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 (MX) Business at Samsung Electronics. “Now, we envision the Galaxy Watch delivering holistic insights centered around sleep — insights that lead to meaningful changes in daily life. We believe this aligns with our vision of empowering people to lead healthier lives through proactive care and holistic health management.”
New Features
Samsung Health’s new features are designed to help users build healthy habits by providing instant feedback as a motivating tool.
Bedtime Guidance
A single night of restful sleep offers immediate health benefits, encouraging proactive behavioral changes that contribute to a healthier tomorrow. This begins with setting and maintaining a consistent, optimal bedtime.
• Samsung continually advances its sleep-related features, including sleep pattern analysis, sleep coaching, tools for optimizing sleep environments and a feature that detects signs of sleep apnea — a common sleep disorder.
• Now, Samsung is introducing additional tools for better sleep, such as recommending an optimal bedtime based on individual lifestyle and sleep patterns along with reminders to help users stay consistent.
• By analyzing sleep data from the past three days, the feature evaluates both sleep pressure and circadian rhythm to suggest a bedtime that maximizes alertness the next day.
• This feature is especially helpful for those recovering from periods of irregular sleep. If users go to bed later than planned for several days or follow inconsistent schedules between weekdays and weekends, Bedtime Guidance will consider these factors to help ensure sufficient rest.
Vascular Load
Sleep is a window into overall health, influencing holistic well-being. The Galaxy Watch series leverages this opportunity to measure vascular load — the amount of stress on the vascular system during sleep.
• The vascular system carries blood throughout the body to deliver oxygen and nutrients while removing waste, making it a key indicator of heart health.
• During sleep, stress on the vascular system should naturally decrease. However, excessive fluctuations may negatively impact cardiovascular health.
• By wearing the Galaxy Watch during sleep, users can receive insights into vascular load and the stress placed on their vascular system.
• Because health factors are interconnected, Vascular Load also provides insight into lifestyle components such as sleep, exercise and stress — helping users maintain a healthier routine and build positive habits.
Running Coach
While sleep is a vital time to restore and support overall health, managing well-being during active moments is equally important. Running is one of the most accessible fitness activities, and Samsung has long supported runners by offering features that promote consistent training and help users reach their fitness goals.
• Many runners experience injuries due to over-pacing or undertraining. Running Coach is designed to help users train safely for marathons through optimized intensity and injury-preventive routines, making it ideal for beginners.
• The feature offers motivation and real-time guidance, creating a personalized training program based on the runner’s fitness level
• By wearing the Galaxy Watch and running for 12 minutes, users receive a performance analysis and a running level score from 1 to 10. Based on this data, a detailed training plan is generated to support completion of a 5K, 10K, half marathon or full marathon. As users complete sessions, they level up and unlock their next running challenge.
Antioxidant Index
A holistic approach to health naturally includes a focus on aging and healthy aging. However, behavioral factors such as alcohol consumption, smoking, UV exposure, stress and lack of sleep can accelerate aging by increasing free radicals in the body that damage cells. Antioxidants, compounds found in many healthy foods, neutralize these free radicals to help prevent chronic illness and support healthy aging.
• The Galaxy Watch can measure carotenoids — antioxidants found in green and orange fruits and vegetables — that are stored in the skin.
• Antioxidant Index uses an industry-first feature to assess carotenoid levels in just five seconds via an advanced, light-activated BioActive Sensor.
• These insights can reflect behavioral changes. For example, drinking carrot juice may result in a measurable change in the index, offering motivation to adopt healthier habits.
Great health comes from the combination of many small changes — and with Galaxy Watch, it’s now more achievable than ever.
