Samsung One UI 8 Watch Brings Advanced Health Features for Sleep, Heart, Fitness, and Nutrition Tracking

Samsung has unveiled a range of new health-focused features coming with the new One UI 8 Watch, designed to help users develop healthier habits by enhancing sleep, heart health, fitness, and nutrition tracking.

Key Features of One UI 8 Watch -

Bedtime Guidance -

This feature offers tailored bedtime recommendations based on your lifestyle and recent sleep data. By analyzing trends from the past three nights, it helps balance sleep pressure with your circadian rhythm. Highlights include:

• Personalized bedtime suggestions aligned with your sleep behavior
• Reminders to stick to a consistent sleep schedule
• Support for resetting irregular sleep patterns
• Enhancements to existing features like sleep trend tracking, personalized coaching, and potential sleep apnea detection

Vascular Load -

A new metric for cardiovascular insights, this feature monitors the strain on your vascular system during sleep. It provides a more comprehensive view of heart health by:

• Measuring vascular stress levels related to sleep
• Detecting abnormal variations that could indicate heart-related issues
• Connecting findings to sleep quality, stress, and physical activity patterns

Running Coach -

Designed for new and casual runners, this feature provides structured training for events like 5Ks or marathons. It includes:

• Real-time feedback and coaching
• A 12-minute running test to assess current fitness level
• Personalized training plans for 5K, 10K, half, and full marathons
• A progress scoring system (1–10) that unlocks advanced stages as you improve

Antioxidant Index -

An industry-first innovation, this feature uses light sensors to assess carotenoid levels in the skin — indicators of antioxidant presence linked to healthy aging. It offers:

• Tracking of antioxidant levels influenced by fruit and vegetable intake
• Visual feedback on how dietary changes impact wellness
• Motivation to adopt healthier eating habits to support long-term health and aging

These updates reinforce Samsung’s ongoing commitment to holistic wellness through smarter, more personalized wearable experiences.

The new features will be introduced with the One UI 8 Watch beta, initially rolling out to the Galaxy Watch5 series and newer models. The beta will first be available in South Korea and the United States.
