What Is a Normal Resting Heart Rate?
Sixty to one hundred beats per minute is the standard range for adults, and a fit person is often below it. Here is how to measure it properly and when to ask about it.
In short
A normal resting heart rate for adults is 60 to 100 beats per minute. Regular exercisers and endurance athletes are often in the 40s or 50s, which is a sign of an efficient heart rather than a problem. Measure it first thing in the morning before getting up, and look for changes over time rather than a single reading.
Resting heart rate is one of the few health measurements you can take with nothing but a clock, and one of the more informative ones once you know what to compare it against.
The range
For adults, 60 to 100 beats per minute is considered normal. That range is wide because it covers everyone from sedentary people to elite athletes, and the useful information is not whether you sit inside it but where.
Regular aerobic exercise makes the heart pump more blood per beat, so it needs fewer beats at rest. Trained people commonly sit in the 50s, and endurance athletes in the 40s. That is efficiency, not a warning sign.
A rate persistently in the 90s while sedentary is within range but worth noting, because it tends to fall with fitness and it is associated with worse outcomes across populations.
How to measure it properly
Wrist and chest devices give a reasonable resting figure, especially the overnight average. Without a device:
- Sit or lie quietly for at least five minutes. Best of all, do it in bed on waking, before coffee and before standing.
- Find your pulse at the wrist below the thumb, or at the side of the neck.
- Count beats for 30 seconds and double it.
- Repeat on a few different mornings. The average is your baseline.
A single reading after climbing stairs, or an hour after coffee, is not a resting rate.
What moves it day to day
Illness, poor sleep, alcohol, dehydration, stress, heat, caffeine and hard training all push it up, usually by 5 to 10 beats. This is why the trend is more useful than any one number. A rate that sits five beats above your normal for a couple of days is often the first sign of a cold, or of not having recovered from a hard week.
When to ask a doctor
- A resting rate consistently above 100 with no obvious cause.
- A rate below 60 with dizziness, fainting, unusual fatigue or breathlessness.
- A sudden, sustained change from your usual baseline with no change in fitness or lifestyle.
- A noticeably irregular rhythm, or palpitations that come with chest pain or shortness of breath.
Occasional skipped or extra beats are common and usually harmless. Persistent irregularity is worth having checked, since some rhythm problems are both common and treatable.
Resting rate and fitness
If you start regular aerobic exercise, expect your resting rate to fall by several beats over a few months. It is one of the clearest, cheapest signs that training is working, and it often shows up before the scales or the mirror do.
Common questions
Is a resting heart rate of 50 too low?
Not if you are fit and have no symptoms. A low rate is common in people who exercise regularly. It is worth discussing with a doctor if it comes with dizziness, fainting, unusual tiredness or breathlessness, or if it has dropped suddenly without a change in fitness.
Why is my resting heart rate higher some days?
Poor sleep, alcohol the night before, dehydration, illness, stress, caffeine and heat all raise it temporarily. A rise of 5 to 10 beats above your usual is a common early sign that you are fighting something off or have not recovered from training.
Does resting heart rate predict health?
Across large populations a lower resting rate is associated with better cardiovascular outcomes, and a rate that rises over years is a mild risk marker. For an individual it is most useful as a trend, since your own baseline matters more than the population average.
