Is your HRV good for your age?
Heart-rate variability (HRV) naturally declines as we age, so a number that looks “low” online might be perfectly healthy for you. Enter your age and your average HRV to see where you actually land.

What is a good HRV for my age?
HRV (measured as RMSSD) tends to fall as we get older. As a rough educational guide, typical ranges look like this:
| Age | Typical HRV (RMSSD) |
|---|---|
| Under 25 | 45–105 ms |
| 25–34 | 38–90 ms |
| 35–44 | 30–72 ms |
| 45–54 | 26–62 ms |
| 55–64 | 22–52 ms |
| 65 and over | 18–45 ms |
These are broad ranges, not medical cut-offs. Your own trend matters far more than any single reading.
Why is my HRV low?
A single low reading usually reflects poor or short sleep, alcohol, stress, illness, dehydration, or a hard workout the day before. One low morning is normal. A steady downward drift over weeks is the more meaningful signal — and it usually points back to sleep, alcohol, or recovery.
Can I improve my HRV?
Often, gradually. The biggest levers are consistent sleep, limiting alcohol, managing stress, gentle aerobic exercise, and staying hydrated. Progress shows up as a rising baseline over weeks — not a bigger number tomorrow.
