Samsung used World Sleep 2025 to spotlight new Galaxy Watch8 sleep capabilities and a broader push into preventative digital health, including tools for developers to build on Samsung Health. The company said the features aim to translate complex biometrics into clearer, actionable insights for users across Asia and beyond. 

SEAO research: shorter nights, higher stress

Samsung shared consumer research across Southeast Asia and Oceania indicating adults average about 6 hours 50 minutes of sleep per night—below the seven to nine hours commonly recommended—while 28 per cent cited “an inability to switch off” as a key concern. Stress was notably elevated among working adults aged 36 to 45, with women feeling the strain more acutely due to work and family responsibilities. The findings point to a regional sleep gap and a need for practical, accessible tools to help users build healthier routines. 

New sleep features and health metrics

Launched in July 2025, the Galaxy Watch8 Series adds multiple sleep tracking upgrades. A Bedtime Guidance feature uses the Two-Process Model of Sleep Regulation—combining homeostatic sleep drive with circadian rhythm—to suggest more consistent, restorative schedules. For users aged 22 and above who have not been diagnosed with sleep apnoea, a software-only Sleep Apnoea feature can flag signs of moderate to severe obstructive sleep apnoea over two nights, prompting users to seek medical attention. Samsung notes the tool is not a substitute for professional diagnosis or treatment. 

Beyond sleep, Watch8 introduces Vascular Load monitoring during sleep to indicate stress on the vascular system—data Samsung says could encourage small lifestyle changes that support long-term cardiovascular health. The watch also expands everyday wellness tracking, including an Antioxidant Index to estimate carotenoid levels in the skin, a Running Coach, stress alerts and guided breathing, and holistic energy scoring. 

At its World Sleep symposium on wearables and next-generation technologies, Samsung said its Samsung Health SDK enables consent-based access to health data for developers, positioning the platform for deeper integrations across its ecosystem. Visitors to Samsung’s booth could take a short sleep survey to learn their sleeper type and explore how features connect to the Samsung Health app. 

“Sleep is a cornerstone of health, and we’re focused on translating biometrics into clear, actionable insights,” said Jong Min Choi, Vice-President of Health R&D at Samsung Electronics, adding that the company’s innovations are designed to help people take “meaningful steps towards better everyday well-being”. 

Wearables are increasingly moving into regulated and quasi-medical territory, with device makers emphasising sleep quality, cardio health and stress management. Samsung’s approach pairs new sensors with software nudges and developer tools to expand use cases while keeping medical guidance with clinicians. 

Samsung said its push into sleep health will continue through the Galaxy Watch roadmap and partner integrations via the Samsung Health SDK. Availability and feature sets may vary by market and require compatible Samsung devices and app versions. Users with suspected sleep disorders should consult healthcare professionals.
