Today, wearable technology can give us information that helps us to build healthy habits and prioritise our long-term wellbeing.
Powered by Samsung’s cutting-edge sensor technology that provides a holistic, real-time overview of our health, the new Galaxy Watch8 series[1] shifts the focus towards 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, Galaxy Watch8 series spots the potential for health issues sooner, so you can prevent them before they start:
- Ectopic Beat Detection: 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. 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[3]: While you sleep, Galaxy Watch8 reads Photoplethysmogram (PPG) waveforms – optical signals associated with blood flow during sleep. It measures blood volume and vascular stiffness and precisely analyses 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[4]: 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 analysing these carotenoids, an antioxidant which reflects fruit and vegetable intake, you are given a score of 0–100, which is categorised 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 to help you add another layer of prevention to your daily routine.
- Bedtime Guidance[5]: 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 personalised 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 energised mornings.
Pioneering the journey to preventative health choices
Samsung’s sensor innovation supports people on their preventative care journeys. The Galaxy Watch8 series helps unify your patterns, expose potential hidden risks, and deliver real-time actionable insights so you can make choices for your health in advance.
[1] Availability and features may vary depending on the smartphone paired; visit https://news.samsung.com/uk/great-health-begins-with-galaxy-watch for details. Not intended for use in detection, diagnosis, treatment of any medical condition. The result is for your personal reference only. Please consult a medical professional for advice.
[2] Samsung Galaxy smartphone required. It is not intended to replace traditional methods of diagnosis or treatment. The feature is not intended for users with known arrhythmias other than AFib. Users should not interpret or take clinical action based on the device output without consultation with a qualified healthcare professional.
[3] Service only available with Galaxy Watch Ultra or later released Galaxy Watch Series. To measure vascular load, it is required to wear Galaxy Watch when sleeping for at least 3 days out of recent 14 days.
[4] Service only available with Galaxy Watch Ultra or later released Galaxy Watch Series. To measure, place the centre of your finger on the sensor at the back of the Watch and hold it for 5 seconds. While Anti-oxidant index can be measured using any finger, the thumb is recommended for the most accurate result. Repeat measurement due to uneven skin texture may lead to inaccurate results.
[5] Bedtime guidance is available on Android phone (Android 11 and above) requires Samsung Health app (v6.30.2 or later). It is based on 3 days of sleep analysis of user’s circadian rhythm and sleep pressure.
