Have you ever looked at your smartwatch and wondered whether it actually knows your body, or whether it is just counting your steps and calling it health tracking?

Samsung’s Galaxy Watch 8 drops to a standout price, but only for a limited time
This £70 discount brings The Samsung Galaxy Watch’s genuine clinical ambition within reach of a much wider audience.
What sets this generation apart most sharply from its predecessors is the antioxidant level sensor, which Samsung claims makes the Galaxy Watch 8 the world’s first smartwatch capable of measuring the AGEs index via a thumb sensor worn overnight.
That sits alongside vascular load monitoring, which requires at least four hours of wear per night over three consecutive nights to build a baseline, then flags when your readings trend upward and suggests whether sleep, diet, or stress management needs attention.
Sleep tracking here goes considerably deeper than a basic summary, breaking down sleep stages, consistency, heart rate, and blood oxygen levels into a picture detailed enough to identify patterns you would not spot from a single night’s data.

The Energy Score pulls all of that together each morning, combining sleep quality, overnight heart signals, and workout recovery into a single daily forecast powered by Galaxy AI, so you start the day knowing whether to push hard or pace yourself.

On the hardware side, the Galaxy Watch 8 is Samsung’s slimmest Galaxy Watch yet, described as 11% thinner than the Galaxy Watch 7, with a 3nm processor driving a 3,000-nit AMOLED display that stays readable in direct sunlight during outdoor sessions.
Built-in GPS tracks runs and walks independently of your phone, a running coach programme tailors a three-to-five week plan to your assessed fitness level, and the 13-day battery life means the watch is still on your wrist by the time your next training block begins.
That £70 discount brings a watch with genuine clinical ambition within reach of a much wider audience, though getting the most from the deeper health features does require committing to consistent overnight wear across multiple nights to build a meaningful baseline.
