Normal resting heart rate: what your number means

You glance at your watch one morning and it says 74. Last month it said 66. Is 74 dangerous? Is 66 good? So you search, find a range of 60 to 100, feel reassured for about three seconds, then get more confused, because the next page says 60 to 70 and a third insists anything above 65 is shortening your life.

None of them is lying. They are answering different questions with the same kind of number. So this page does not start with a figure. It starts with where the figures came from, because that is the only route to reading your own.

What resting heart rate actually is

Your resting heart rate is how many times your heart beats per minute while you are awake, still, and not affected by exertion, stress or food. It reflects how much blood your heart has to move to keep you going when nothing much is happening.

Two things determine it. The first is how much blood your heart pushes out per beat. The second is how hard your nervous system is driving. A larger, stronger heart moves more per beat and therefore needs fewer of them. A nervous system in a higher gear, from stress, short sleep, infection or caffeine, pushes the rate up regardless of how strong the heart is.

That is what makes the number interesting. It sits at the intersection of what your fitness looks like across months and how your body is coping right now. It is also exactly why it is so easy to misread: the same rise can come from a hard session yesterday or from a cold that has not announced itself yet.

What counts as normal, and why the numbers disagree

Here is the uncomfortable part. There is no single figure. There are several, they measure different things, and two of them sit side by side on the same national health service website.

1177, Sweden's public health guide, states on its page about taking your pulse that a resting adult usually has a pulse of between 60 and 70 regular beats per minute. The same page notes that a well-trained person is often lower, between 45 and 55 beats or below. On 1177's page about palpitations, however, the figure given is that an adult heart usually beats 50 to 100 times per minute.

Both are correct. The first describes what people typically sit at. The second describes what a heart can reasonably do without anything being wrong. That is the difference between a typical value and an outer boundary, and it is almost always the thing that gets lost when these numbers are quoted onward.

That last row is the most widely repeated of them all, so it deserves its own explanation.

This is the same class of discovery as finding out that 10,000 steps a day came from the name of a Japanese pedometer rather than from a study. We covered that in the guide on how many steps a day you actually need. A number can become received wisdom through repetition instead of through measurement.

Your watch is not measuring what a clinic measures

This is the most common reason people believe something is wrong with them, and the easiest one to clear up.

When 1177 describes how to take your pulse, it means fingers against the artery in your wrist, counting for a full minute, and you may sit, stand or lie down. That is a snapshot of a single waking, usually upright moment.

A watch or a ring does something else entirely. It computes a single value per day using its own closed formula. In the largest study in this area, that value is described as intended to represent the pulse you would have lying down, immediately after waking, before getting out of bed. Lying down and newly awake, your pulse is normally lower than sitting up in the middle of the day.

So your watch can read 58 while a nurse counts 71, with neither of them wrong. They are measuring different body positions at different times of day by different methods. The practical rule follows directly.

There is now good data for watch wearers specifically. A study published in PLOS ONE in 2020 followed 92,457 adults across the United States who wore heart-rate tracking wristbands for at least 35 weeks. The dataset covers close to 33 million daily values, which made it the largest dataset on resting heart rate assembled at the time it was published. The overall average was 65.5 beats per minute.

The spread is the interesting part. Among participants, 95 percent of men fell between 50 and 80 beats. For women the equivalent band was 53 to 82. Women sat higher in every age bracket. Include the extremes and the gap widens considerably: individual averages ran from 39.7 all the way to 108.6 beats. The study's own conclusion is that two people's normal values can differ from each other by as much as 70 beats per minute.

Seventy beats. That is the whole point of this page. Against a spread that wide, the question "is 74 normal" becomes close to meaningless, while the question "is 74 normal for me" is exactly the right one.

The curve peaks around 50, which is to say mid-life

If you are over 40 and have been told your pulse only climbs with age, there is a detail in the same study worth knowing. Average resting heart rate rose with age until roughly 50 years old. After that it began trending back down.

The curve is not a rising line but a hump, built from comparisons between age groups rather than from following the same people through life, and the peak sits close to the age many of us are. That means two things in practice. A resting heart rate in the upper part of the range right now is statistically expected rather than a sign of decline. And a comparison against a decade you are not in tells you less than a comparison against yourself in the spring.

The same study found two other patterns that are easier to act on than age. The lowest resting heart rates clustered at a BMI of around 21 for women and 23 for men, rising in both directions from there. And the lowest values belonged to people sleeping between seven and seven and a half hours a night. The sleep link is worth noting, but note what was actually measured: the study compared participants' average sleep duration with their average resting heart rate. It did not track one short night against the next morning's reading. What actually changes about sleep after 40 is covered in the guide on sleeping better after 40.

How to build your own baseline

Since the level matters less than the change, the first real job is knowing what you normally sit at. Without a baseline, every morning reading is just a number with no context.

1. Measure the same way every time. A watch or ring already does this for you. If you are counting by hand, do it lying in bed before you get up, two fingers against your wrist, for a full minute. Do not use your thumb, which has a pronounced artery of its own that is easy to mistake for the one you are trying to feel.
2. Collect for at least two weeks. One morning tells you nothing. Fourteen tell you where you normally sit.
3. Take a typical value, not your best one. The lowest number you have ever seen is not your resting heart rate. The middle of your mornings is.
4. Write down the context. Late nights, alcohol, hard sessions, colds. Without those notes you will be guessing at the cause every time the number moves.
5. Refresh the baseline every few months. Fitness changes. A baseline from last year describes a different body.

What a change means

Here is the most useful statistic in the whole dataset, because it hands you the line between noise and signal.

In that study of 92,457 people, the typical variation within a single week was only about 3 beats per minute. For roughly 80 percent of participants, the largest weekly swing stayed under 10 beats. At the same time, 20 percent had at least one week where the number moved by 10 beats or more, so it does happen.

The researchers also looked at clear deviations, defined as a resting heart rate more than two standard deviations above the person's own average across at least three consecutive readings. Those episodes occurred a median of three times over two years, with a range from zero to seventeen.

Translated to your morning:

Notice what the table does not do. It does not diagnose anything. A raised resting heart rate knows that something is costing your body more than usual, but it never knows what. That distinction is the whole game, and it applies to every recovery metric there is. How to weigh resting heart rate against heart rate variability is covered in the guide on HRV and what the number actually tells you, which works through how the two figures can vote together.

High resting heart rate and risk: what the link does not say

This section exists because you will run into alarming headlines on this subject, and because the research behind them is real but considerably more careful than the headlines are.

One large synthesis is a meta-analysis published in CMAJ in 2016, built on 46 prospective cohort studies covering just over 1.2 million participants and 78,349 deaths. The findings:

• Every increase of 10 beats per minute was associated with a relative risk of 1.09 for death from any cause.
• Compared with the lowest category, people with a resting heart rate above 80 had a relative risk of 1.45.
• Even the 60 to 80 band sat slightly above the lowest category, at 1.12 for all-cause mortality.
• The associations held after adjustment for traditional cardiovascular risk factors.

A larger 2017 review in Nutrition, Metabolism and Cardiovascular Diseases covered 87 studies and arrived at 1.17 per 10 beats for all-cause mortality, the same direction but a higher figure. That two syntheses of the same question produce different numbers is itself a statement about how precisely this can be measured.

That third point in the list above is the one that tends to become a headline about how a "normal" pulse is dangerous after all. Before you take it to heart, four caveats belong with it. The first two come from the CMAJ meta-analysis itself. The last two are our own reading of what evidence like this can carry.

First, the corresponding figure for cardiovascular death in the 60 to 80 band was 1.08, with a confidence interval running from 0.99 to 1.17. That crosses 1, meaning it did not reach statistical significance. An association that might be zero should not be described as a finding.

Second, the authors report that they found substantial heterogeneity between the included studies along with evidence of publication bias. That is a warning from the researchers themselves that the pooled figure is shakier than its decimal places suggest.

Third, these are observational studies. They show that a high resting heart rate travels with higher risk, not that the pulse causes it. An elevated resting heart rate is often a marker for something else: low fitness, poor sleep, ongoing illness, sustained stress, excess weight. Lowering the number with a beta blocker in a healthy person would not buy the health the statistics describe.

Fourth, and most important for how you use any of this: a relative risk of 1.12 in a population study is not a verdict about you. It is a faint pattern across hundreds of thousands of people. Your resting heart rate of 74 says nothing about how your particular life will go.

What actually lowers it

Training lowers resting heart rate. The question is by how much, and the honest answer is less dramatic than the expectation.

A systematic review in the Journal of Clinical Medicine in 2018 worked through 191 studies covering 215 comparisons. For endurance training, group averages fell from 72.4 to 68.0 beats per minute, a drop of about 6 percent. Control groups moved from 72.3 to 71.9, which is to say essentially not at all. Across all forms of exercise, the difference against controls came to roughly 3.3 beats per minute.

The endurance groups fell 4.4 beats, the controls 0.4. Four beats net, then. That is a real effect. It is also a long way from the "resting heart rate of 45 in three months" that circulates on running forums. Three further findings from the same review are worth carrying with you:

• Only endurance training and yoga lowered resting heart rate significantly in both sexes. Strength training did reach significance across all 43 of its comparisons (69.1 to 67.8 beats against controls' 68.9 to 69.0) and in women, but not in men and not in the mixed groups.
• The higher you start, the more there is to gain. The size of the drop tracked with the starting value, though only moderately (r = 0.30 across 215 comparisons).
• Groups with a higher average age saw smaller drops. The authors state it directly: the higher the average age, the smaller the reduction. That is not a reason to skip the training. It is a reason not to measure yourself against a 25-year-old's curve.

That it is the calm, aerobic work doing the job fits how the rest of the week ought to look. Why most of your sessions belong at low intensity is covered in the guide on zone 2.

What raises it, usually harmlessly

Before worrying about an elevated morning reading, it is worth walking the list of ordinary causes. 1177 lists the following as situations where your pulse may rise: physical exertion, stress or fear, pain or fever, major blood loss, coffee, nicotine or too high a dose of certain medicines, attempts to quit nicotine or medicines, a period of heavy drinking, along with hyperthyroidism, a blood clot in the lung, or lung conditions that leave the body short of oxygen.

Exertion, stress, pain, coffee, nicotine and alcohol explain the overwhelming majority of the rises a healthy person sees on a watch. The remaining entries on the list, such as major blood loss, hyperthyroidism and a clot in the lung, are uncommon but real. That is precisely why a rise that persists without explanation belongs with a clinician rather than in an app.

Two of the most common causes deserve a note. Alcohol is on 1177's list of things that can raise your pulse, and it usually shows up in the morning number. And mental pressure raises resting heart rate without your needing to feel stressed, which is what makes the figure a useful early indicator. How to handle a long stretch under pressure is covered in the guide on stress management.

A low resting heart rate: when it is good and when it is not

A low resting heart rate is usually a good sign. In someone who has trained consistently for years, 50 or just below is exactly what you would expect, and 1177 gives 45 to 55 or lower as common among well-trained people.

But a pulse can be low for other reasons. 1177 lists medicines such as beta blockers, calcium channel blockers and digitalis, along with a block in the conduction of the heart's impulse between the atria and the ventricles. Fainting appears on the list too. Becoming fitter is on that same list, which means the ordinary cause and the uncommon one sit right next to each other.

The rule that separates them has nothing to do with the number: a low pulse without symptoms in someone who trains is expected, while a low pulse with symptoms needs assessing. The symptoms that matter are dizziness, faintness, unusual breathlessness on light exertion, and a fatigue that does not match your training load.

If you take medication that affects your pulse, both your resting heart rate and your training zones stop being comparable to any table. What that means for training is covered in the section on rate-altering medication in the guide on zone 2.

What resting heart rate cannot answer

Four honest limits, so you do not ask the number to carry more than it can.

• It does not know the cause. A raised resting heart rate means your body is working harder than usual. Whether that is training, short sleep, wine, heat, stress or an infection is decided by you and the context, not by the figure.
• It is not a fitness test. Resting heart rate relates to fitness but does not measure it. Two people with the same resting heart rate can have markedly different aerobic capacity.
• It is not comparable across devices. Every manufacturer computes its daily value with its own formula. Change your watch and you change the measurement method, so a jump in the number when you switch devices is not a change in your body.
• It does not replace an examination. No consumer device diagnoses anything. If you feel irregular beats, or you have symptoms, an ECG is what gives you an answer.

When to seek care

This section follows 1177's guidance on palpitations and altered heart rhythm. If you are outside Sweden, use your own local emergency number and health service.

• Call emergency services immediately if you have irregular heartbeats together with chest pain, or if someone has fainted.
• Contact a clinic or urgent care immediately for intense palpitations that will not settle, or for dizziness or brief fainting during exertion or while sitting or lying down. If the clinic is closed, go to an emergency department.
• Contact a clinic as soon as you can for recurring trouble with palpitations.
• Book an appointment if your resting heart rate has sat clearly above your usual level for several weeks with no explanation, or if you have a low pulse together with dizziness, unusual breathlessness or heavy fatigue.
• In Sweden, call 1177 if you want help assessing symptoms or advice on where to seek care.

This is general health information, not a diagnosis or personal medical advice. If your doctor has given you guidance or treatment, that takes precedence over everything written here.

Frequently asked questions

What is a normal resting heart rate?

Sweden's national health guide 1177 states that a resting adult usually has a pulse of 60 to 70 regular beats per minute, and that a well-trained person often sits at 45 to 55 or lower. The wider 60 to 100 range you see quoted everywhere is a clinical threshold for deciding when a rhythm needs a closer look. It was never a statement about what is desirable.

Is a resting heart rate of 75 too high?

No. A reading of 75 falls inside what counts as normal for a healthy adult. In a dataset of 92,457 people wearing heart-rate tracking wristbands, 95 percent of men fell between 50 and 80 beats per minute and 95 percent of women between 53 and 82. But a single reading of 75 tells you very little on its own. What matters is whether 75 is normal for you, or whether you were sitting at 64 in the spring.

Why does my watch show a different resting heart rate than my doctor?

Because they are two different measurements. A pulse counted with fingers for one minute captures a single moment while you are sitting upright. A watch or ring instead computes one value per day using its own closed formula, typically intended to approximate your pulse lying down immediately after waking, before you get out of bed. Lying down and newly awake, your pulse is normally lower. So compare your watch reading against your watch's own history rather than against a clinical table.

How much can resting heart rate swing before it means anything?

In a study of 92,457 people, the typical variation within a single week was only about 3 beats per minute, and for roughly 80 percent of participants the largest weekly swing stayed under 10 beats. A couple of beats up or down is noise. What deserves attention is a clear rise that persists for several days, or a level that has crept upward over weeks.

How much will my resting heart rate drop if I start training?

Less than most people hope, but enough to see. In a review of 191 studies, endurance training moved group averages from 72.4 to 68.0 beats per minute while control groups barely budged. Two patterns are worth knowing. The higher you start, the more there is to gain. And groups with a higher average age lowered their resting heart rate less than younger groups did.

Is a low resting heart rate always a sign of fitness?

Not always. In someone who trains regularly, a low resting heart rate is expected and harmless. But a pulse can also be low for other reasons, including beta blockers, calcium channel blockers or digitalis, or a disturbance in the heart's conduction system. The deciding factor is not the number but whether you have symptoms. A low pulse together with dizziness, faintness, unusual breathlessness or heavy fatigue should be assessed by a clinician.
