I’m constantly testing smartwatches, but I’ve never experienced such intense curiosity as when I’m wearing an Oura Ring. “Is that one of those rings that tracks everything?” people ask. I can’t blame them. How exactly can something so small offer all the same tracking features as a smartwatch?

When you order an Oura Ring online from the US (the only way to get it), you get to choose your ring’s design, finish, and size. I opted for the ‘horizon’ design and selected the silver finish. If you opt for a ‘stealth’, ‘gold’ or ‘rose gold’ finish, the ring is considerably more expensive ($349 for silver versus $549 for rose gold). 

The most crucial part, however, is determining the right size for your finger. Oura offer a free sizing kit, which arrived within days of ordering. This kit contained eight plastic rings in different sizes, allowing me to find the perfect fit. Oura recommends that you test the plastic sample rings on your index finger for 24 hours to ensure it’s comfortable when you sleep. If you don’t fancy wearing on your index finger, they say the middle and ring fingers are good alternatives. 

Once I found the perfect size, I downloaded the Oura app on my phone and delved into its world of tracking – and I was impressed. Not only does it keep tabs on basic metrics like heart rate and activity levels; it also digs deep into some pretty vital aspects of health that often go unnoticed. Plus, it boasts remarkable battery life, usually lasting between four to seven days on a single charge and super quick charging times – usually taking between 20-80 minutes.

The sleep tracking feature is a game-changer. The Oura ring assigns a ‘Sleep Score’ (ranging from 1 to 100), that evaluates the quality of your sleep based on various factors including sleep stages (such as how much time you spent in REM vs. deep or light sleep), body temperature and heart rate. It’s amazing to see how a glass of wine or heading to bed just an hour later than usual can mess with your sleep. I particularly liked how the Oura ring offers tips on how to improve your sleep too – with the app pinging notifications on when it’s time to start winding down for bed.

Lots of watches – including Garmin, Fitbit and Apple – offer menstrual cycle tracking for women, but I was impressed with the accuracy the Oura ring offered. For example, on day 22 of my cycle, the Oura app told me that while my ‘readiness level’ was good, my body temperature was slightly elevated – but this may just reflect normal temperature fluctuation across the menstrual cycle. I’ve found this feature really useful – it’s definitely helped me to better understand my body during different phases of my cycle.

The Oura ring also provides a ‘Readiness Score’, which looks at things like temperature and heart rate variability, to assess how ready you are for the day ahead. It can detect early signs of illness and help you prioritise rest and recovery. It’s like having a personal sleep doctor, PT and GP on your finger, nudging you to make smarter choices.

My only gripe? I found the metal can easily get scratched and can scratch other jewellery. Oura does recommend taking the ring off when strength training or lifting heavy weights, but isn’t the point of the ring to wear it 24/7 so it gets a complete overview of how you exercise?

Overall though, if you’re looking for a fitness tracker that seamlessly fits into your everyday wardrobe, the Oura Ring has accurate tracking capabilities, plus unique features like menstrual cycle tracking. It is expensive though, and for some – especially those training for specific goals like a marathon – you may prefer to have all your data visible on your wrist, rather than depend on your phone.

The World Health Organization’s (WHO) 2020 guidelines recommend 150–300 min of moderate-intensity or 75–150 min of vigorous-intensity activity per week, which is associated with a 20–30% reduction in all-cause mortality risk.

In a recent study published in the journal Healthcare, researchers at the University of South Australia investigated the effectiveness of the 15-Minute Challenge, a mobile health (mHealth) initiative that supports workplace wellness by promoting physical activity and improving health outcomes among employees across various workplaces.

Encouraging physical activity at work

The World Health Organization (WHO) highlights that regular physical activity reduces the risk of chronic conditions like cardiovascular disease, diabetes, and obesity. Physical activity is essential for preventing chronic diseases and improving overall health; however, many adults do not meet recommended levels, which significantly contributes to global health issues.

Since many adults spend most of their time at work, workplace environments often encourage sedentary behaviors, which increase the risk of various health problems. Thus, workplace wellness programs can be a valuable strategy that promotes physical activity among employees.

The 15-Minute Challenge is an initiative that uses mHealth technology and behavioral economics to encourage employees to engage in short, daily physical activity sessions. By focusing on a manageable 15-minute daily commitment, this program aims to make exercise more accessible and sustainable while also incorporating elements of gamification, such as team competitions and social sharing, to motivate participation.

About the study

The current study evaluated the effectiveness of the 15-Minute Challenge in improving employees’ health outcomes and increasing physical activity. To this end, the researchers used a retrospective cohort design to evaluate the six-week wellness program across various workplaces in Australia, New Zealand, and the United Kingdom.

The program facilitated daily 15-minute sessions for physical activity, with participants recording their activities using a mobile app. To motivate participation, the app featured gamification elements like team competitions, social sharing, and personal milestones.

Study participants reported their health and well-being, including energy, fitness, mood, sleep quality, and overall health, at the beginning and end of the program using a 10-point scale. Usage data, including frequency of app interaction and engagement with specific features, were also collected.

The program’s effectiveness was analyzed using statistical models comparing baseline and end-of-program health outcomes. Program analytics measured participation and retention rates, while post-program surveys gathered user feedback on satisfaction and perceived benefits. Statistical analyses were performed to assess changes in physical activity levels and health outcomes.

Study findings

A total of 11,575 participants employed by 73 companies across the U.K., Australia, and New Zealand recorded 19 million minutes of physical activity, with 69.6% of study participants reporting daily activities. By the end of the study period, 70.8% of study participants were still actively participating in the program. The median daily exercise duration was 45 minutes, and participants averaged 34 active days during the study period.

Significant improvements were observed in health metrics, as sleep quality, mood, energy levels, overall health, and perceived fitness increased by 7.6%, 7.1%, 11.6%, 7.7%, and 14%, respectively. Additionally, the number of participants meeting or exceeding international physical activity guidelines rose from baseline levels of 57.3%  to 95.4% during the program.

User feedback was positive, with 92% willing to recommend and rejoin the program; however, only 42% of study participants reported reduced stress levels. Overall, the program effectively increased physical activity levels and improved health outcomes, thus demonstrating its potential as a workplace wellness intervention.

Conclusions

The 15 Minute Challenge, a workplace wellness program, significantly increased physical activity levels and improved various health outcomes, such as fitness, energy, overall health, sleep quality, and mood among employees.

By the end of the program, most of the study participants met or exceeded international physical activity guidelines. High satisfaction levels were also reported, with a significant majority of participants willing to recommend the program.

The study findings highlight the potential of work-based interventions to enhance mental and physical health, which could lead to benefits like increased productivity and reduced absenteeism.

Notable limitations of the current study include its reliance on self-reported data and the absence of a control group, which could introduce biases and limit the ability to attribute the observed changes to the program directly.

Future research should incorporate more rigorous study designs, like randomized controlled trials, to confirm these findings. Exploring strategies to sustain engagement and examining long-term health impacts, as well as the effects of the program on workplace outcomes like employee morale and productivity, would also provide valuable insights.
