Wearable tech has never been more in vogue, but the world seems to have moved on from fitness watches, something the Duke of Sussex cottoned on to years ago.

Prince Harry has been wearing an Ōura Ring since at least 2018, having first debuted the wearable technology on his royal tour in Australia with his wife Meghan Markle, two years before they bowed out of the royal spotlight.

The father-of-two was seen wearing Ōura's Heritage ring in black on his right hand, which features a classic plateau design.The device, which starts at £299, promises to track temperature, sleep efficiency and heart rate variability, in turn offering its wearers the opportunity to become more in tune with their body.

For years I've debated whether or not I should invest in the Ōura Ring, but as I enter my second month of wearing it, I can already sense that my relationship with this genius gold band is set for the long run.

From the first few nights of wearing it, I became hooked on checking my Sleep Score each morning, which calibrates your awake time, light sleep, REM and deep sleep during your time in bed. Depending on your sleep, Ōura gives you a 'Readiness' score, which determines how ready your body is to take on the day.
