Hannah Fry’s Oura Ring data proves how stressful Celebrity Traitors is - here's what the clever device measures
The star shared her stress insights from the day the episode was filmed to reveal her state of mind
If you're watching Celebrity Traitors this year, you'll know last night's episode was particularly eventful - but no spoilers here! Hannah Fry, mathematician and University of Cambridge professor, was at the centre of the drama, with her mind and strategic instincts put to the test.
The star revealed just how stressful the episode really was for her, sharing a view of her Oura Ring on Instagram. As one of the best smart rings, the Oura Ring sensors continually read your heart rate, skin temperature, heart rate variability (HRV), and activity. In the app, you'll see these complex metrics in readable graph formats and at the end of your day as a Stress Score.
Hannah's data shows she was particularly on edge at about 1 pm and just after 6 pm on the day she filmed the episode, with constant pressure in between, suggesting these were the challenging moments we saw last night.
"My smart ring during filming for that episode 📈📈📈," she wrote on Instagram under the graph.
Viewers flew into her comments after she posted, with one saying: "YOU READ MY MIND! I was thinking exactly that when I clocked that [Oura ring] on your finger 😂. Mine looked fairly similar watching it!"
Another said: "I bet you relished that one hour of restorative time tbh".
And another wrote: "We need to see the sleep score for that night".
The scientist wears the Oura Ring 4 in ceramic white, the second-latest model from the health tech brand. This one is thicker than the latest Oura Ring 5, but more durable, and it comes in exciting colourways.
What is the Oura Ring and what does it track?
The Oura Ring is a smart ring. It's a tracker that sits on the index or middle finger and measures essential vitals, including live heart rate, activity (daily and dedicated workouts), blood oxygen, body temperature, respiratory rate, and sleep activity.
In the Oura app, you can see these vitals in colourful and easy-to-read formats, such as your Readiness Score. This takes your activity and recovery together to determine how well-rested your body is.
Sleep Score is an overview of how long you slept, sleep stages (light, deep, REM, and awake), your sleep schedule, and breathing rate. It'll tell you how your night was, and even flag potential signs of sleep apnoea.
The ceramic Oura Ring 4 comes in several colours, including Hannah's bright white. Midnight blue, pastel green, white, and petal pink are also options.
While the Oura Ring isn't specifically a fitness tracker, there is an Activity Score. This is out of 100, like the others, and it reveals how your everyday movement (whether that's simply moving around the house or dedicated workouts) impacts your body, heart health, and metabolic health.
The Stress Score is the one that Hannah was looking at. Not all stress is bad, and Oura knows that. So, you'll see an overview of your stress levels for the day across four labels: Stressed, Engaged, Relaxed, and Restored. You'll also get an overview of what that means for your body and be notified if your stress levels need adjusting.
Beyond these short-term metrics, Oura uniquely measures long-term health. No one bad day impacts your wellbeing. In the 'My Health' tab, you'll see an AI overview of your health over the past 90 days. Here, you can drill down into your sleep, stress, and heart health and see the impact (positive or negative) of small daily habits.
The Oura Ring is not a medical device, but it can be very useful for flagging potential early signs of key health issues that you can then speak to your doctor about.
