One member put it bluntly: HRV is now less a metric than a moral compass, telling us to drink less, breathe more, fetishize recovery and treat a late night as self-sabotage.
The clinical question underneath is serious. Are we tracking HRV because it improves outcomes, or because patients and physicians find it emotionally compelling? Goodhart's law applies: when a measure becomes a target, it stops being a good measure. Morning and nighttime HRV also measure different things.
The goal is stress tolerance, not a better number on a ring.
Key takeaways
- HRV is a useful signal, not the outcome.
- Name the difference between the metric and the goal explicitly with patients.
