People with high heart rate variability are usually less stressed and happier. If your heart rate is highly variable, this is usually evidence that your body can adapt to many kinds of changes. Your heart’s variability reflects how adaptable your body can be. Here’s how the Cleveland Clinic describes HRV: Many health and fitness professionals consider HRV as one of the best metrics to know when your body needs rest or is ready to perform as well as giving insight into the condition of your autonomic nervous system.Īlong with HRV, Cardio Fitness – based on VO2 max – is a valuable metric to be aware of that can be indicative and predictive of overall health. While it may sound like a bad thing at first, a higher HRV is actually indicative of being healthier, happier, less stressed, and can mean you’re recovered and are ready to exercise. In late 2022, we saw the most recent study published that shows Apple Watch is precise at tracking HRV.

But there have been studies that show Apple Watch is as reliable as products like the Polar’s heart rate monitors for measuring HRV. Some medical professionals contend measuring HRV through the skin with smartwatches isn’t as accurate as dedicated medical equipment. You don’t notice these tiny variances but devices like Apple Watch capture HRV, which is measured in milliseconds.

HRV stands for heart rate variability and is the measurement of how the interval of time between heartbeats changes.
