Riyadh, Saudi Arabia – Aug 10, 2025 -  Navigating today’s scattered health data and a healthcare system geared towards treating illness, not preventing it, hinders our ability to build healthy habits and prioritize long-term wellbeing. So how do we take back control?

Powered by Samsung’s cutting-edge sensor technology that provides a holistic, real-time overview of our health, the new Galaxy Watch8 series1 shifts the focus to preventative care. It provides clear, actionable insights based on your lifestyle patterns to help you understand your body and mind more deeply, build healthy habits and help identify silent threats such as ectopic beats early on.

▲The Galaxy Watch8 series’ Antioxidant Index allows you to monitor your antioxidant intake by measuring carotenoid levels in the skin.

Preventative Care Through Early Detection

With new heart metrics, the Galaxy Watch8 series spots the potential for health issues sooner, so you can prevent them before they start:

Ectopic Beat Detection: Ectopic beat detection refers to the process of identifying premature heartbeats that originate from locations other than the sinoatrial (SA) node, which is the heart’s natural pacemaker. The Galaxy Watch8’s enhanced Electrocardiogram (ECG)2 can better capture ectopic beats – premature heartbeats that often go undetected in routine checkups as they frequently occur without noticeable symptoms. It is well known that frequent ectopic beats can be considered clinically significant and may lead to arrhythmias that drive up stroke and heart-failure risk. The Galaxy Watch8 series provides enhanced ECG measurement with the ability to differentiate instances of frequent ectopic beats providing earlier insights to support preventive care.

Vascular Load: While you sleep, the Galaxy Watch8 reads Photoplethysmogram (PPG) waveforms – optical signals associated with blood flow during sleep. It measures blood volume and vascular stiffness and precisely analyzes changes in stress on blood vessels. Because diet, stress, and rest all affect this metric, regular monitoring shows which habits to fine-tune and helps you cut cardiovascular risk before it takes hold.

Lifestyle Changes Motivated by Sensor-Driven Insights

The Galaxy Watch8 series’ advanced sensor now gives you more immediate insights for your nutrition and sleep patterns to steer you towards lasting, sustainable habits:

Antioxidant Index: Because lifestyle often outweighs genetics, the Galaxy Watch8 series shines a light on your daily choices. The BioActive Sensor measures skin carotenoids in five seconds using multi-wavelength absorption spectroscopy. After analyzing these carotenoids, an antioxidant which reflects fruit and vegetable intake, you are given a score of 0–100, which is categorized into one of three levels. This score shows how diet, UV light, alcohol and stress are impacting your antioxidant levels. With insufficient fruit and vegetable intake linked to major health risks, this non-invasive metric offers meaningful insight, promotes healthier choices and adds another layer of prevention to your daily routine.

Bedtime Guidance: Leveraging the science behind the two-process model of sleep regulation, the Galaxy Watch8 series tracks your circadian rhythm (internal body clock) and sleep pressure (how much your body needs sleep), over three days. It then interprets this data as a differential equation to calculate the optimal bedtime for waking up refreshed. The algorithm uses changes in sleep threshold and individual sleep needs throughout the day to deliver personalized guidance. Developed by KAIST and clinically tested at Samsung Medical Center, this feature helps build healthier sleep routines that lead to deeper, less interrupted sleep and more energized mornings.

Pioneering the Next Era of Preventative Care

Samsung’s sensor innovation is setting a new standard for preventative care. The Galaxy Watch8 series helps unify your patterns, expose hidden risks, and deliver real-time actionable insights so you can safeguard your health in advance. Samsung is not only redefining what a smartwatch can do today, but also accelerating the next wave of preventative-care breakthroughs for tomorrow.
