Understanding Your Normal Rate for Heart Rate and HRV
By Teemu Arina ·

The normal rate for heart rate in a resting adult is often quoted as 60–100 beats per minute (bpm), but this is a starting point, not a personal target. A fuller picture includes what is typical for the individual and how heart rate changes with activity, sleep and stress; heart rate variability (HRV) can add another signal.
The standard benchmarks for resting heart rate
Resting heart rate is the number of beats per minute when the body is at rest. The 60–100 bpm range is a broad adult benchmark; lower rates can be normal for some people, including trained athletes. One reading outside the range does not establish a health problem.
The review Heart rate as an independent risk factor for cardiovascular disease: current evidence and basic mechanisms describes associations between resting rates and higher risk of hypertension and atherosclerosis, and discusses risk increasing across rates above 60 bpm. Resting heart rate in cardiovascular disease also notes that a single optimal rate is difficult to define. These are population-level associations, not a diagnosis or personal prediction.
Adult reference points do not apply to babies or children: a systematic review found median heart rate changes substantially from birth through childhood, declining as children grow (systematic review of heart rate ranges in children). A 24-hour ECG study of healthy adults aged 50–65 also found different reference ranges for mean ambulatory and minimum heart rate. The ranges varied with when and how readings were measured (reference ranges for ambulatory heart rate).
Why your normal rate for heart rate varies
Heart rate shifts with exertion, emotional strain, sleep, illness, medication and other influences. An average heart beat rate across a monitoring period answers a different question from a reading taken while sitting quietly.
The 2023 review Importance of resting heart rate describes heart rate as shaped by several physiological inputs, including sympathetic and parasympathetic activity and the heart's intrinsic rhythm. Changes over time may have predictive value, but why heart rate relates to outcomes in otherwise healthy people is not fully understood (review of the importance of resting heart rate).
A UK electronic health record study found that associations between resting heart rate and some cardiovascular outcomes differed between men and women. The study cannot interpret an individual reading. Its findings show that one number is not a universal threshold (linked health-record study of resting heart rate and cardiovascular outcomes). Compare readings taken in similar circumstances; discuss a rate that is repeatedly unusual or accompanied by concerning symptoms with a qualified health professional, rather than relying on a wearable alone.
Understanding heart rate variability (HRV)

This illustration contrasts a steady heart rate with the rhythmic variations that define heart rate variability.
Heart rate counts beats per minute; HRV describes variation in the intervals between successive beats. They are related but measure different things: the intervals can vary even when the average rate is steady.
In "Defining Chronotypes With Biosignals, A Look Into Data" at Biohacker Summit 2017 Helsinki, Hannu Kinnunen discussed HRV alongside body temperature as biosignals for examining circadian alignment, sleep and recovery. He presented them as measures to consider, not as a stand-alone verdict on health.
The phrase hrv heart rate variability often appears in searches about wearable readings. HRV is most useful as a pattern compared with a person's own readings over time, using reasonably consistent devices and conditions. The papers cited here focus primarily on heart rate, not clinical HRV reference ranges. For age-related context, see Heart Rate Variability by Age: What Your Number Means.
Kinnunen suggested noticing how routines align with the body's rhythms. A change in HRV can prompt consideration of context; it does not identify a specific cause.
The role of circadian rhythms and chronotypes
Heart rate follows daily rhythms as the body moves between activity, rest and sleep. Chronotype describes a tendency towards earlier or later timing. In his Biohacker Summit 2017 talk, Kinnunen said chronotypes are biologically influenced and lifestyle can adjust them only to a limited degree.
Every function in our body has its optimum time in the twenty-four-hour cycle.

Kinnunen said natural timing and daily schedules can conflict: people with later chronotypes may catch up on sleep during days off, while social demands make their preferred rhythm difficult to follow. He recommended considering biosignals and sleep patterns together.
Treat a wearable's chronotype estimate as one clue. Consider whether energy, sleep and recovery follow a repeatable pattern, and whether work or family regularly requires a conflicting schedule. Where possible, organise daily life around more consistent rhythms.
How breathwork influences your heart signals
In "Breathing Beyond The Ego" at Biohacker Summit 2022 Amsterdam, Kasper van der Meulen described breathwork as a way to influence the body's state and discussed the vagus nerve's role in physiological responses.

Once you recognize that you are a biological being and you start to look at the buttons that you can push in order to tune this biological being, you can be very accurate with the way that you change your state.
— Kasper van der Meulen, Biohacker Summit 2022 Amsterdam
A low-pressure experiment is to breathe comfortably for a few minutes and notice whether the breath becomes slower or more even. Keep breathing comfortable; avoid forcing deep breaths or chasing a particular HRV reading. The talk presents breath as a tool for changing state. It does not show that one routine improves everyone's HRV or changes cardiovascular outcomes.
The talks point to context: sleep timing, daily demands and breathing practices may be worth observing. A device cannot identify what caused a change.
Monitoring trends instead of single data points
Timing, movement, sleep and measurement conditions can affect a single heart-rate or HRV reading. Compare readings using the same device where possible, at similar times and in similar circumstances; repeated patterns are more informative than a surprising one-off number.
The 2023 review discusses the potential value of temporal changes in heart rate. The 2024 ambulatory study reports separate reference ranges for mean, minimum, daytime and night-time readings. A quiet resting measurement and a daily average are different measures.
Note relevant context, such as unusual sleep or a measurement taken after exercise. The goal is to spot persistent changes and consider them alongside how the person feels, not explain every fluctuation. Wearables can support observation, while clinical assessment remains important.
The HOLOLIFE Summit 2026 in Amsterdam is scheduled for 14–15 November 2026.
FAQ
What is a healthy resting heart rate?
The commonly quoted adult resting range is 60–100 bpm, but a healthy reading depends on the person and measurement circumstances. Age, fitness, medication and other factors matter, so a consistent personal pattern is more useful than one reading.
How does heart rate variability differ from heart rate?
Heart rate is beats per minute; HRV is variation in the time between successive beats. They measure different features and neither should be interpreted alone.
Can stress affect my normal heart rate?
Heart rate reflects several physiological inputs, including sympathetic and parasympathetic activity, and changes with a person's state. Stress may be part of the context, but a heart-rate change alone cannot identify its cause.
How can I improve my heart rate variability?
The talks discuss biosignals, circadian patterns and breathwork as ways to observe or influence aspects of physiological state, but do not establish a guaranteed method for raising HRV. Consistent measurements can reveal patterns; a higher score should not be treated as a health goal in itself.
