Building healthy habits is one of the best things we can do to achieve long-term benefits and prevent illness, but it is not something many of us can do reliably and without guidance. Samsung believes the new Galaxy Watch 8 series can help.

Equipped with the latest health and fitness-tracking features, the Galaxy Watch 8 lineup is Samsung's most complete to date. Combined with Galaxy AI, these powerful tools guide you toward building healthier habits and spot potential health issues before they become greater problems.

Today, Samsung highlighted a few extra details about four of the latest Galaxy Watch 8 features that enable you to detect health issues early on and create healthier habits. These include:

Premature heartbeats that originate from locations other than the sinoatrial (SA) node can lead to arrhythmias that increase stroke and heart failure risk.

According to Samsung, the Galaxy Watch 8's enhanced ECG tool can better detect ectopic beats that often go undetected in routine checkups.

The Galaxy Watch 8 is equipped with the right tools to read photoplethysmogram waveforms. These are optical signals associated with blood flow during sleep.

Samsung's smartwatches can monitor blood volume and vascular stiffness and analyze changes in stress on blood vessels. By regularly monitoring vascular load, the Galaxy Watch can show you which habits you can improve and help decrease cardiovascular risk.

Our lifestyle and diet can accelerate the aging process, and small daily choices can have a significant impact on our long-term health. Antioxidants can help us age slower, but our diet, alcohol intake, stress, and UV light can have a significant impact on antioxidant levels.

The Galaxy Watch 8's new Antioxidant Index feature lets you monitor this aspect by analyzing carotenoids — an antioxidant that reflects fruit and vegetable intake. The embedded BioActive Sensor can measure skin carotenoids in five seconds and offer a score from 0 to 100.

This tool makes it easier for you to adjust your diet and other aspects of your lifestyle to improve antioxidant levels and age better. You won't see immediate benefits, but this clever tool can greatly help you in the long run.

Good sleep can go a long way in achieving better health, especially if you can get better rest every night. Once again, the Galaxy Watch 8 series can help you through the new Bedtime Guidance feature, which can offer personalized tips on how to achieve better sleep.

The Galaxy Watch 8's BioActive Sensor tracks your circadian rhythm and sleep pressure (how much your body needs sleep) over three days, after which it interprets the data and gives you an optimal bedtime. By following this guide, you can achieve better sleep and wake up refreshed.

Apart from the four main features listed above, Samsung's Galaxy Watches can also help your fitness routine through the following:
