Samsung Galaxy Watch to Get Vitals, Heart Health Score, Daily Cardio Load, Fitness Index, and More Features

Samsung has revealed a major update to Samsung Health that will debut on its upcoming Galaxy Watch lineup. The company says the goal is to move beyond simple health tracking and offer more personalized guidance based on data collected throughout the day and night.

The update starts rolling out on June 8 and introduces several new features designed to help users better understand their sleep, activity levels, cardiovascular health, and overall wellness.

The Focus Is Shifting From Data to Actionable Insights

Smartwatches have become increasingly good at collecting health data. The challenge for many users is understanding what that information actually means.

Samsung's latest update appears to address that issue by using AI to turn raw biometric data into simpler recommendations. Instead of presenting users with charts and numbers alone, the company wants Galaxy Watch to provide clearer guidance on when to rest, train, or pay closer attention to their health.

The new features will first be available on Samsung's next-generation Galaxy Watch models.

New Vitals Feature Tracks Changes in Your Baseline Health

One of the biggest additions is a feature called Vitals.

Rather than simply recording overnight health data, Vitals analyzes five key measurements while you sleep: heart rate, heart rate variability, respiratory rate, skin temperature, and blood oxygen levels.

The system compares those readings against your personal baseline and only sends notifications when it detects meaningful changes. Samsung says this approach is intended to reduce unnecessary alerts while helping users identify signs of fatigue, illness, or recovery needs.

Heart Health Gets a Single Daily Score

Samsung is also introducing a new Heart Health Score.

The feature combines data related to sleep, stress, activity levels, and body composition into a single daily metric. Instead of checking multiple health indicators separately, users get one score designed to highlight habits that may be affecting long-term cardiovascular health.

It's essentially an evolution of Samsung's existing Vascular Load feature, but presented in a more simplified format.

Daily Cardio Load Aims to Prevent Overtraining

For users who exercise regularly, Samsung is adding Daily Cardio Load.

The feature measures accumulated cardiovascular strain and uses that information to recommend workout intensity and recovery periods.

Rather than encouraging users to push harder every day, Samsung says the system is designed to help balance training and recovery to reduce the risk of burnout or injury.

A New Fitness Index Tracks Long-Term Progress

Another new feature is Fitness Index, which focuses on long-term fitness improvements.

The tool looks at factors such as heart rate, daily step count, and VO2 Max, a commonly used measure of aerobic fitness. Samsung says it will compare results against similar users and provide personalized goals based on individual strengths and weaknesses.

The idea is to make it easier for users to see whether their workouts are actually improving fitness over time.

Samsung Health Is Getting a New Look

Alongside the health features, Samsung is redesigning the Samsung Health app.

The new layout is organized around five categories: Sleep, Activity, Nutrition, Mindfulness, and Vitals.

Users will also be able to access their Energy Score and daily wellness recommendations directly from the home screen, reducing the need to navigate through multiple menus.

Hearing Health and Nutrition Tracking Are Also Expanding

Samsung is updating several existing wellness tools as well.

The Antioxidant Index will now include trend charts and historical data to help users understand how dietary choices affect their health over time. The company's AGEs tracking system has also been improved to collect more data automatically during overnight monitoring.

Another new addition is Hearing Health. By using sensors across the Galaxy ecosystem, including Galaxy Watch, the feature can monitor ambient noise exposure and provide insights aimed at helping users protect their hearing.
