Your heart beats around 100,000 times a day on average. Every beat carries information — not only about the heart muscle, but about the overall state of your nervous system, your inflammatory load and your biological age.
How to read the numbers: Target = the value we aim for · Risk = what to watch out for
Optimal RHR
A resting heart rate of 50–65 beats per minute usually indicates good cardiovascular fitness, and higher values are associated with greater risk in studies. Measure it in the morning lying down right after waking and watch the long-term trend, not a single day.
Good variability
Heart rate variability (HRV) shows how flexibly your nervous system responds to stress and rest; values are, however, highly individual and depend on age and measuring method. Compare yourself with yourself – a drop below your own average often signals insufficient recovery.
for every +10 beats
Observational studies found that each 10-beat-per-minute rise in resting heart rate goes along with a higher risk of death, though this shows an association, not direct causation. The most reliable ways to lower your resting heart rate are regular endurance exercise and good sleep.
Resting heart rate (RHR)
Normal range: 60–100 beats/min. Optimum for longevity: 50–65 beats/min. Every 10-beat increase in RHR raises the risk of a cardiovascular event by 18%. Aerobic training is the most effective way to lower your RHR in the long term.
Most mammals have a lifespan of around 1 billion heartbeats. A person with an RHR of 50 theoretically has more beats "in reserve" than someone with an RHR of 80. It's not just a metaphor — a slower heart rate is associated with a longer life across many studies.
HRV — heart rate variability
HRV measures the variability of the intervals between heartbeats. Paradoxically, higher variability = better health. Low HRV signals sympathetic dominance (stress, inflammation, overtraining). High HRV signals a well-adaptable nervous system.
