Understanding Oura Ring’s Cardiovascular Age

My Oura Ring has delivered some exciting news—my cardiovascular age is 11 years below my actual age. This is a significant finding that suggests my cardiovascular system is functioning exceptionally well compared to the average person my age. But what exactly does this mean, how is this number calculated, and how does my result compare to others? Let’s dive into the science behind this fascinating metric.

Understanding Cardiovascular Age

Cardiovascular Age (CVA) is a relatively new feature in the Oura ecosystem that provides an estimate of how your heart and large arteries are aging compared to your chronological age. This metric is designed with an eye toward your future health and longevity, offering insights into your cardiovascular system’s overall condition^1,3.

The concept is based on a fundamental biological principle: younger, healthier arteries are more elastic, expanding and contracting efficiently in response to changes in blood flow. As we age naturally, our arteries tend to stiffen and lose some of their elasticity. This stiffening can eventually cause the energy of each heartbeat to place additional strain on our internal organs¹.

Having a cardiovascular age significantly below your actual age—like my 11-year difference—suggests that your arteries are maintaining the elasticity and functionality typically seen in someone much younger. This is generally considered a positive indicator of both current cardiovascular health and potential long-term health span².

How Oura Calculates Your Cardiovascular Age

An impressive cardiovascular age reading isn’t just a random number—it’s calculated using sophisticated technology embedded in the Oura Ring. The process works through several key steps:

1. The ring uses photoplethysmography (PPG) sensors—the same technology used to measure heart rate—to assess the characteristics of your blood flow during sleep^1,6.
2. These measurements calculate your pulse wave velocity (PWV), which indicates how quickly your heartbeat pulse travels throughout your body. PWV is widely accepted as a key indicator of arterial stiffness^1,3.
3. Faster pulse waves are associated with stiffer, less flexible arteries, while slower pulse waves typically indicate more elastic, healthier arteries¹.
4. By analyzing the shape of your heartbeat’s signal during sleep, combined with your biological data (including sex, actual age, and height), Oura interprets these measurements into an age estimate^1,4.
5. This calculation requires at least 14 nights of data from the past 30 days to establish a baseline reading, which is why consistent wear is important for accurate results¹.

My cardiovascular age of 11 years below my actual age places me firmly in the “Below” category of Oura’s classification system, which is defined as 6 or more years below your chronological age. This is the most favorable category within Oura’s three-tier system (Below, Aligned, and Above)¹.

How My Result Compares to Others

My cardiovascular age result is particularly impressive when compared to the broader Oura user population. According to aggregate data from Oura, the average member has a cardiovascular age approximately 1.76 years younger than their chronological age².

This means my result of 11 years younger is significantly better than the average Oura ring user, placing me among those with exceptionally healthy cardiovascular systems for their age.

For perspective, even in countries with the best cardiovascular health metrics among Oura users, the averages are still not as impressive as my individual result. For instance, as of late 2024, members in Sweden topped the list with an average CVA of 2.63 years younger than their chronological age. Norway, Netherlands, Switzerland, and Denmark rounded out the top five countries with the best cardiovascular age readings².

What Influences Cardiovascular Age?

An excellent cardiovascular age reading is likely the result of multiple positive lifestyle factors. Research and Oura’s data suggest that CVA is affected by numerous elements, including:

1. Regular physical activity: Exercise strengthens your cardiovascular system and improves circulation, contributing significantly to arterial health^1,2.
2. Diet: Heart-healthy eating patterns, particularly those including fatty fish and other omega-3 rich foods, can positively impact arterial flexibility².
3. Work-life balance: Stress management and adequate recovery time appear to correlate with better cardiovascular metrics².
4. Genetic factors: Some people naturally maintain more elastic arteries due to their genetic makeup¹.
5. Other health markers: Blood pressure, cholesterol levels, and smoking status all play important roles in arterial health and cardiovascular age¹.

The Scandinavian lifestyle, which typically involves regular outdoor activity regardless of weather, consumption of heart-healthy foods, and a strong emphasis on work-life balance, seems particularly beneficial for cardiovascular health according to Oura’s data analysis².

Maintaining An Excellent Cardiovascular Age

You’re likely curious about how to maintain or even improve your cardiovascular health. While my current habits are clearly working well, here are some evidence-based approaches to attain your excellent cardiovascular age:

1. Continue regular exercise: Consistent physical activity remains one of the most powerful tools for cardiovascular health².
2. Focus on recovery: Ensure adequate sleep and recovery periods between workouts to allow your cardiovascular system to adapt and strengthen¹.
3. Monitor long-term trends: Cardiovascular age changes slowly, so focus on the relative trend over time rather than small fluctuations^4,5.
4. Maintain heart-healthy dietary patterns: Emphasize whole foods, adequate protein, healthy fats, and plenty of fiber².

Important Considerations

While a good score is certainly positive, there are a few things to keep in mind:

1. The measurement is an estimate, not a direct medical assessment of your cardiovascular health⁷.
2. Certain medical conditions might affect measurement accuracy, including Raynaud’s Syndrome (which affects blood flow to fingers) and various heart conditions⁴.
3. The reading represents your current cardiovascular status; continued healthy habits are essential for maintaining this positive result¹.

Conclusion

An Oura cardiovascular age 11 years below chronological age is an exceptional result that suggests the cardiovascular system is functioning at a level typical of someone significantly younger. This positive indicator reflects the elasticity and health of the arteries, potentially contributing to better long-term health outcomes.

My result places me well ahead of the average Oura user, who typically shows a cardiovascular age about 1.76 years below their chronological age. Even users in countries with the best cardiovascular metrics don’t average results as impressive.

While this metric should be viewed as complementary to (rather than a replacement for) regular medical check-ups, it provides valuable insight into how your lifestyle choices may be positively affecting one of your body’s most crucial systems. By maintaining your current healthy habits and perhaps incorporating additional heart-healthy practices, you can work toward an excellent cardiovascular status for years to come.
