HRV by age: understand your own readings

Age is one part of the picture, but a single age chart cannot tell you what your own HRV means. The device, measurement method and your usual pattern matter too.

What is HRV?

It describes small changes in the time between heartbeats. It is different from heart rate, which counts beats per minute.

Compare like with like

• Use the same device and method where possible.
• Compare similar recording periods.
• Check for gaps in the data.
• Look at your own pattern rather than chasing another person’s number.

Add what was happening

Notes about sleep, training and daily life can help you discuss changes. A chart is a record to explore, not a diagnosis or a test you pass.

If a change worries you

Do not use an online chart to rule out a health problem. Seek healthcare advice if you have symptoms or persistent concerns.
