In an attempt to win the European Championship, England manager Gareth Southgate and his team have resorted to titanium health rings worn by some of the world's biggest celebrities.

Oura Rings have been provided to Southgate, the players, and the England staff for them to wear throughout the Euros so that their heart health, stress levels, and sleep patterns can be tracked in Germany.

"We're beaming with pride when we see these elite athletes choose Oura, that's really cool," said Dorothy Kilroy, the company's chief commercial officer, to Sky News.

England defender John Stones already wore an Oura Ring before the Euros. Speaking last year, Stones said: “The first thing I do once I’m out of bed is check my Oura Ring to see how I’ve slept – it’s addictive.

“It tells me how long it took me to fall asleep, how much REM [rapid eye movement] and deep sleep I managed, how many times I woke up…it’s mad.”

Dave Thomas is the lead on "future technology" at the UK Sports Institute, where he works with Olympic and Paralympic athletes from England.

According to him, the ring might provide the sports scientists for the England team with an alternative viewpoint on how their players are performing throughout the competition.
