What is a good HRV by age?

6 MIN READ · VITRA HEALTH

“What’s a good HRV for my age?” is one of the most-searched HRV questions, and the honest answer frustrates people: there’s a typical range by decade, but it varies so much between individuals that your own baseline matters far more than any chart. Here’s both halves of that answer.

HRV falls with age

Heart-rate variability tends to decline as we get older — broadly, a healthy person in their twenties will average higher than the same person in their fifties. That’s normal and not in itself a problem. It’s why comparing your number to a twenty-something’s, or to an athlete’s, is a recipe for needless worry.

Typical ranges by decade

As a rough orientation only: nighttime rMSSD (what Oura reports) often runs higher in the 20s and trends down each decade thereafter, with very wide overlap between age groups. Published averages exist, but the spread within any decade dwarfs the difference between decades — two healthy 40-year-olds can sit 40 ms apart. Treat any “good HRV by age” table as a loose backdrop, never a target.

Why your own baseline beats the chart

Because the between-person spread is so large, a population average can’t tell you whether your number is good. An HRV of 45 might be excellent for one person and a warning sign for another. What’s reliable is the comparison to yourself: is today near your own rolling average, climbing, or dropping? That question is answerable and actionable; “is 45 good?” mostly isn’t.

How to read yours

Wear the ring consistently for a few weeks to establish your baseline, then watch the trend and the normal range around it rather than the absolute figure. A multi-day decline is worth heeding; a single low night usually isn’t. And remember the everyday movers — alcohol, late meals, stress, hard training — before reading anything dramatic into a dip. None of this is medical advice.

Vitra grades your HRV against your own rolling baseline and its normal range, and explains each day in plain English — so you get “normal for you” or “lower than usual, here’s the likely reason” instead of an age chart you can’t map onto yourself.

Frequently asked questions

What is a normal HRV by age?

HRV generally declines with age — averages are higher in your 20s and trend down each decade — but the spread between individuals is far larger than the difference between age groups. Two healthy 40-year-olds can differ by 40 ms, so treat any age chart as loose orientation, not a target.

Is a low HRV always bad?

No. A single low night is usually just noise from alcohol, a late meal, stress or hard training. What matters is a sustained multi-day decline relative to your own baseline, not one dip or how your number compares to someone else's.

What HRV does Oura measure?

Oura reports overnight rMSSD in milliseconds, averaged across the night while you're at rest. Because it's measured the same way every night, it's well suited to tracking your personal trend rather than hitting an absolute target.
