[World Heart Day] Taking Care of Your Heart Every Day, Starting From Your Wrist

No matter who you are or what you do, we all have one constant companion we rely on every single day: our heart. Unseen but always at work, it beats around 100,000 times a day, keeping pace with us through every moment. Yet for something so essential to our lives, taking care of our hearts is often overlooked until it’s too late.

World Health Organization (WHO) recognizes Sept. 29 as World Heart Day. It is a reminder that the choices we make today can make a meaningful difference tomorrow.

These choices don’t have to be big. From choosing when to go to bed to making time for even just 30 minutes of exercise, the small choices we make every day add up to a healthier lifestyle. The good news is that Samsung Galaxy Watch can help you make proactive prevention part of daily life. By monitoring your sleep, activity level, stress and blood pressure, Galaxy Watch helps you better understand what’s happening in your body.

Understanding Your Body at a Glance: Heart Health Score

The American Heart Association recommends looking at Life’s Essential 8[1] as key measures for improving and maintaining cardiovascular health: diet, exercise, sleep, weight, blood pressure, blood sugar, cholesterol and smoking cessation. But knowing what matters raises an important question: how do these factors change the choices we make every day?

Samsung Health’s Heart Health Score[2] is designed to help you in this journey. It tracks and analyzes indicators such as sleep duration, daily activity level, body composition and vascular load,[3] converting them into a single, simple score that anyone can intuitively understand and follow.

Think about what happens if you miss your daily exercise for a few days: your Galaxy Watch recognizes your moderate-to-high intensity activity level has decreased, reflects this change in a lower Heart Health Score, and makes a recommendation to go for a run. With convenient insights right from your wrist, Galaxy Watch delivers personalized insights that make it easier to recognize changes, understand your habits, and take the next step toward healthier ones.

Advanced Sensor Technology: From Measurement to Meaning

Samsung Galaxy Watches are equipped with an advanced BioActive Sensor which integrates three precision sensors in one: an optical heart rate sensor (PPG), an electrocardiogram sensor (ECG),[4] and a bioelectrical impedance analysis sensor (BIA).

With calibration just once every four weeks using a home blood pressure monitor, you can easily check your blood pressure[5] from your wrist anytime, anywhere. When you place your finger on the watch’s side electrode for just 30 seconds, the watch measures an electrocardiogram to detect signs of abnormal heartbeats like atrial fibrillation or ectopic beats. The Irregular Heart Rhythm Notification (IHRN)[6] feature, which detects abnormal heart signals, monitors the user’s heart rhythm throughout the day and provides a proactive notification if abnormal signs are repeated.

Around-the-Clock Care: How Galaxy Watch Proactively Monitors Your Wellness

Your heart is a constant you can count on, and it works whether you’re awake or asleep. When you wear your Galaxy Watch to sleep, it analyzes five major vital signs: heart rate during sleep, heart rate variability,[7] respiratory rate, skin temperature and blood oxygen saturation. These signals are compared against your personal baseline.

When you wake up, your Galaxy Watch will send a notification if it detects meaningful deviations from your baseline. By highlighting meaningful changes early, it gives you an opportunity to rest and recover.[8]

Heart to Heart: Connected Care That Adds Peace of Mind

Looking after your own heart is only one side of the story. From parents to partners, siblings to grandparents or even friends, the burden of caring for the hearts of those around you weighs heavily. Samsung Health’s Health Data Sharing[9] function lightens the load by sharing agreed-upon data items (number of steps, blood pressure, heart rate, medication adherence, etc.) with loved ones in real time.

You can check if your parents who live far away have completed their daily walk or taken their prescribed medication on time, just as if you were right there with them.

Samsung Health lets users share selected health data with loved ones, helping them stay connected and informed about one another’s wellbeing. (Image simulated for illustrative purposes. Actual UX/UI may be different.)
