We detail everything you need to know about Garmin’s recovery feature
Heart rate variability has become the cornerstone of recovery-focused metrics on top sports watches, but Garmin’s HRV Status possibly takes it a step further.
Once you get to grips with how HRV Status works, it can be a good additional tool for understanding the body’s adaptation to training.
However, if you’re new to HRV Status and want to know exactly how it works or which Garmin watches it’s available on, you’re in the right place.
And if you’re just getting started with HRV, you may want to read our quick explainer of what heart rate variability is and what it means.
What is Garmin HRV Status?
Most sports watches and fitness trackers only register an average HRV figure from your previous night’s sleep, leaving you to fill in the gaps and determine whether this is within a typical range or not.
Meanwhile, Garmin’s HRV Status establishes a baseline of your typical HRV range and assesses your recovery in a broader context, then provides an easy-to-understand summary of your own data.
That said, remember that Garmin’s HRV is not a medical diagnostic tool, but rather a supplementary tool that gives you an idea of your HRV range.

Explained: How Garmin measures HRV
Garmin uses optical photoplethysmography (PPG) from the wrist heart-rate sensor to measure HRV. Some other wearable devices may measure it using ECG-capable sensors or calculate HRV in a different way, which makes Garmin’s readings stand out. Additionally, what Garmin does with the HRV data is also a bit different.
Garmin records your HRV during sleep, measuring the time between heartbeats in milliseconds. Then, the data is charted using averages of five-minute windows throughout the night.
Your Garmin will take around three weeks to establish your heart rate variability range, though you will still be able to view individual nightly averages during this period. Remember that to get approximately correct HRV baseline readings, you should wear your watch for at least 4 nights per week.
Then, once the baseline is established, Garmin compares your rolling 7-day HRV average with your personal HRV range.
Everybody’s range is individual, with some showing naturally higher variation and other people’s range being much tighter.
This baseline is also dynamic. Following a period of extended training, for example, this range of variability may trend lower than a period of little training or peak condition.
Understanding your HRV Status: How to use it
Once the context has been gathered, HRV Status gets to work, and you’ll be given one of four statuses based on your 7-day rolling average: Balanced, Unbalanced, Low, or Poor.
Balanced
If your HRV Status is Balanced, it means your rolling average is within your personal variation range, indicating your body is likely adapting well to current demands and recovering as expected.
Unbalanced
If the status is Unbalanced, the 7-day rolling average is outside your established personal variation range, which can occur when the figure is both lower and higher than the typical range.
High HRV values are typically associated with a greater parasympathetic nervous system, so why is this considered Unbalanced in HRV Status?
According to Garmin and wider research, unusually high HRV values relative to your baseline can sometimes occur during periods of accumulated fatigue or overreaching.
One explanation is that prolonged training stress may occasionally lead to unusually elevated parasympathetic activity, pushing HRV above an individual’s baseline.
Low
If your 7-day rolling average drops below your established baseline range, you’ll be assigned the Low status.
In our experience, this may occur after a prolonged period of increased training, stress, disrupted sleep, or illness. As we mentioned earlier, an extended period at a lower HRV value will also shift the baseline.
Poor
While HRV Status typically works against your personal range, the Poor tag is reserved for when your long-term HRV baseline falls below age-based norms associated with good health.
When this occurs, you’ll notice that a baseline is no longer provided. Garmin indicates this is to avoid denoting an unhealthy baseline as Balanced.
Like with the Low marker, we’ve noticed that a sudden illness can quickly push our HRV Status into the Poor zone.
