OURA Ring 4 Valuable Insights
i. Sleep
Your Sleep Score is meant to provide you with a holistic perspective of how well you’re sleeping on a daily basis (overall sleep quality). Oura ring 4 analyzes your sleep by measuring the dynamics of your body temperature, resting heart rate, movement, and time spent in specific sleep stages, including light, deep, and REM.
Interpreting OURA Ring 4 Sleep Scores
See below OURA Ring 4 Sleep score interpretation on a scale of 0-100%.
85-100: Optimal
70-84: Good
60-69: Fair
0-59: Pay Attention
An 85 or higher may be a sign that you are ready to take on new challenges. Scores below 70 indicate that you may benefit from prioritizing rest and recovery in the indicated areas.
ii. Heart Rate
The wellbeing of your heart is one of the most powerful contributors to your overall health and longevity. OURA Ring 4 will give you the basic 24/7 heart rate monitor to understand how your body responds to your daily habits, stressors and environment. Other insights include your cardiovascular age, Cardio Capacity and Heart Rate Variability(HRV).
iii. Cardiovascular Age[CVA].
The OURA Ring 4 Cardiovascular Age (CVA) provides an estimate of how your heart is aging compared to your actual known age, as well as guidance on how you can improve your heart health in the long run, for longer, better, healthier life.
iv. Cardio Capacity
The OURA Ring 4 Cardio Capacity also referred to VO2 Max in other smart wearables provides a window into the health of your heart and is tied to longevity. The greater your Cardio Capacity, the greater your body’s ability to supply oxygen to your muscles during physical activity.
v. Heart Rate Variability[HRV]
The heart changes its rhythm with each beat. This constant variation in milliseconds between your heartbeats is known as your heart rate variability(HRV). HRV is a powerful signal that reflects the heart’s adaptability to different situations, providing insights into potential stress or sickness levels and overall wellbeing.
As a rule of thumb:
• Higher HRV is associated with rest-and-digest, general fitness, and good recovery
• Lower HRV is associated with fight-or-flight responses, stress, illness, or overtraining
vi. Arterial Stiffness
As you age, your arteries naturally become less flexible or stiff — a process known as large artery stiffening. arterial stiffness is measured using PWV(Pulse Wave Velocity). PWV is the speed at which your blood flows through them. As arteries stiffen, the speed at which blood flows through them, or PWV, speeds up.
While age is the primary cause of this stiffening process, studies show that lifestyle factors such as smoking, an unhealthy diet, poor sleep, or a sedentary lifestyle, as well as health conditions such as high blood pressure, high cholesterol, or obesity, can also speed it up. OURA uses peer reviewed reference ranges that have been found to match well with OURA’s member population.
vii. Activity Score
OURA Ring 4 measures your activity Score using your daily activities (how much you move throughout the day), step count, training frequency, and training volume, among other metrics. OURA Ring 4 registers all daily movement, including both step-based activities like walking and running, as well as non-step-based activities like light housework.
On your OURA Ring 4 app, you can also set an activity goal and add activities.
