SAN FRANCISCO – In a groundbreaking development, the Oura Ring, known for tracking sleep and stress, has unveiled a new feature: blood sugar monitoring. This innovation, in partnership with Dexcom’s Stelo, a continuous glucose monitor (CGM) designed for non-diabetics, aims to help users understand how their eating habits affect their health.
Immediate Impact
For years, the Oura Ring has been a staple for health enthusiasts seeking to monitor their sleep and recovery. However, its new capability to track blood sugar levels marks a significant enhancement. The collaboration with Stelo offers users a deeper insight into the cause-and-effect relationship between diet, energy, and mood.
“By combining Stelo data with Oura’s existing insights, we’re empowering members to better understand the cause-and-effect relationships between eating patterns, energy, mood, and recovery — and ultimately make sustainable, science-backed lifestyle changes,” said Maz Brumand, vice president of product for Oura, in a statement to CNET.
Key Details Emerge
Over a two-week period, testing the Stelo CGM with the Oura Ring led to surprising revelations about dietary impacts. This type of biofeedback, according to experts, is beneficial for everyone, not just those with diabetes.
Understanding Continuous Glucose Monitoring
Blood sugar, or glucose, is the primary energy source for the body. According to the Cleveland Clinic, when we consume carbohydrates, glucose levels rise, prompting the body to release insulin. This process is vital for energy regulation. However, frequent spikes or crashes can affect energy, mood, and long-term health.
“Glucose is a real-time window into metabolic health, which underpins how we feel day to day — our energy, focus, mood, and sleep — and how resilient we are over time,” Brumand noted.
Industry Response
The introduction of wearable glucose sensors like Stelo allows non-diabetics to gain insights into their metabolic health without the need for invasive procedures. This development represents a significant shift in health monitoring technology.
Normal Glucose Ranges and Spikes
Before using a CGM, many might assume that blood sugar levels should remain stable. However, spikes are normal, particularly after meals. The American Diabetes Association suggests a target range for adults without diabetes between 70 and 140 mg/dL. Clinical studies show that moderate spikes are common and not necessarily a cause for concern.
“Clinical studies show that even in healthy individuals, a moderate glucose spike (rise above 140 mg/dL) can occur daily,” explained Renee Fitton, a registered dietitian.
By the Numbers
- 70-100 mg/dL: Normal fasting glucose range
- Under 140 mg/dL: Typical post-meal glucose level
- 30-40 calories: Burned during a 10-minute walk, aiding glucose management
Background Context
The Oura Ring’s collaboration with Stelo builds on the growing trend of personalized health monitoring. This development comes as more individuals seek to understand their metabolic health beyond traditional metrics.
Setting Up the Stelo Monitor
Users can purchase the Stelo sensor directly from Oura. The setup process is straightforward, involving a quick and painless application to the upper arm. Once paired with the Stelo app, glucose levels are tracked continuously for up to 15 days.
Expert Analysis
Dietitian Renee Fitton emphasizes the importance of understanding glucose spikes. “The biggest area of concern when managing our blood sugar levels is limiting refined carbohydrates,” she stated, advising on food pairing to manage spikes effectively.
Practical Applications
Testing revealed that even healthy foods could cause spikes. For instance, a nutrient-dense pressed juice caused a temporary spike, prompting a reconsideration of fruit-heavy beverages. In contrast, a homemade smoothie with added protein and fiber kept glucose levels stable.
“Even natural fruit juices can cause glucose spikes, especially when consumed on an empty stomach,” Fitton explained.
What Comes Next
The findings suggest that managing blood sugar is not solely about dietary choices but also about timing and physical activity. A simple walk after a meal can significantly impact glucose levels, demonstrating the importance of lifestyle in metabolic health.
As wearable technology continues to evolve, the integration of glucose monitoring in devices like the Oura Ring could pave the way for more personalized health insights, empowering users to make informed lifestyle changes.
