Your resting heart rate is the number of times your heart beats per minute while you are awake, calm, and still. For most people aged about ten and older, including adults of every age, the normal range is 60 to 100 beats per minute, according to the American Heart Association and Mayo Clinic. It is one of the simplest windows into cardiovascular health, and it is easy to measure yourself.
People often expect resting heart rate to shift steadily with each decade of adult life, but that is not really how it works. This guide lays out how resting heart rate actually varies by age, what makes a rate healthy, and what can push it up or down. Different Health measures cardiovascular fitness directly and reads resting heart rate alongside it, rather than treating the number in isolation.
What resting heart rate is
Resting heart rate reflects how hard your heart works when you are not active. When you are fit, your heart pumps more blood with each beat, so it needs fewer beats per minute to supply the body. That is why a lower resting rate is generally a sign of a more efficient, better-conditioned heart.
It is worth separating resting heart rate from heart rate variability, which people sometimes confuse. Resting heart rate is simply how many times your heart beats per minute. Heart rate variability is the variation in timing between individual beats. They are related but different measures, and this article is about the first.
Resting heart rate by age
The honest picture of resting heart rate by age is that the big changes happen in childhood, not adulthood. Babies and young children have naturally fast heart rates that decline as they grow into the adult range. Once you reach adulthood, the normal range holds steady, and differences between healthy adults are driven more by fitness than by age.
| Age group | Typical resting heart rate |
|---|---|
| Newborns and infants | Much higher, roughly 100–160 bpm, falling with growth |
| Children (about 1–10) | Roughly 70–120 bpm, still declining with age |
| Age 10 and older, including adults | 60–100 bpm |
| Well-trained adult athletes | Often 40–60 bpm |
Typical resting heart rate by age (approximate; per AHA, Mayo Clinic, and Cleveland Clinic)
Because the adult range does not move much with age, a healthy 30-year-old and a healthy 65-year-old can share the same resting heart rate. Older adults sometimes run slightly higher, but fitness, medications, and health conditions explain most of the variation you see between adults. This is educational information rather than personal medical advice.
What counts as a good rate
A good resting heart rate generally sits toward the lower end of the normal range, since a lower rate usually reflects better cardiovascular fitness. Many fit adults land in the 50s or 60s, and well-trained endurance athletes can be in the 40s.
A lower resting heart rate usually means the heart is working more efficiently, and it often reflects better cardiovascular fitness.

There is no single perfect number, though, and lower is not always better without limit. A very low rate accompanied by dizziness, fatigue, or fainting is not a sign of fitness and should be checked. The most useful benchmark is your own stable baseline, which is why tracking your resting heart rate over time tells you more than any one reading against a chart.
What affects it, and how to lower it
Many things move resting heart rate day to day and over time. Fitness lowers it, while stress, poor sleep, dehydration, caffeine, alcohol, nicotine, and certain illnesses raise it. Some medications lower it, such as beta-blockers, and an overactive thyroid can push it above 100. Knowing these influences helps you read your own number in context.
To lower resting heart rate for the long term, regular aerobic exercise is the most reliable approach, since it strengthens the heart to pump more per beat. Consistent sleep, stress management, hydration, and limiting stimulants all help too, with changes building over weeks to months. Because resting heart rate reflects fitness, it is best understood next to a direct measure of it, like the VO2 max testing covered in our guide to VO2 max. Different Health measures your cardiorespiratory fitness in-lab and pulls your wearable resting heart rate and heart rate variability into the same dashboard, so the number sits in a fuller picture.
When to see a doctor
A resting heart rate consistently above 100 beats per minute is called tachycardia, and one consistently below 60 is bradycardia. A low rate is often healthy in fit people, so the deciding factor is usually symptoms. See a doctor if a high or low rate comes with dizziness, fainting, chest pain, shortness of breath, or palpitations, or if your resting heart rate changes suddenly and stays changed from your usual baseline.
These situations are worth prompt attention because heart rate is a vital sign that can reflect an underlying issue. Different Health's assessment includes cardiovascular and thyroid markers in its DH360+ bloodwork, reviewed by its MDs, which helps put an unusual resting heart rate in context, though it complements rather than replaces care from your own doctor for symptoms.
Key Takeaways
- Normal range: for adults of all ages, a normal resting heart rate is 60–100 bpm.
- Age matters most in childhood: children's rates start high and fall with growth; the adult range is stable.
- Fitness drives adult differences: well-trained adults often sit in the 40s to 50s.
- Lower usually means fitter: a lower rate reflects a more efficient heart, within reason.
- Know your baseline: a sustained change from your normal matters more than a chart.
- See a doctor: a high or low rate with symptoms, or a sudden lasting change, needs evaluation.
Frequently Asked Questions
What is a normal resting heart rate by age?
For most people aged about 10 and older, including adults of all ages, a normal resting heart rate is 60 to 100 beats per minute, according to the American Heart Association and Mayo Clinic. Babies and young children have naturally higher rates that gradually fall as they grow. Among adults, the normal range stays broadly stable with age; the bigger differences come from fitness, since well-trained adults often sit between 40 and 60 beats per minute.
What is a good resting heart rate?
A good resting heart rate generally sits toward the lower end of the normal 60-to-100 range, because a lower rate usually reflects better cardiovascular fitness and a heart that pumps efficiently. Many fit adults are in the 50s or 60s, and well-trained endurance athletes can be in the 40s. There is no single ideal number, though. What is good depends on the individual, and a rate that is normal and stable for you matters more than hitting a specific figure.
Does resting heart rate increase with age?
Not dramatically in adults. The normal resting heart rate range of 60 to 100 beats per minute applies across adulthood, so age itself is not the main driver of differences between healthy adults. The largest age-related change happens in childhood, when heart rates start high and decline toward the adult range with growth. In adults, fitness, stress, medications, and health conditions influence resting heart rate more than age alone does.
When is a resting heart rate too high or too low?
A resting heart rate consistently above 100 beats per minute is called tachycardia, and one consistently below 60 is called bradycardia. A low rate can be perfectly healthy in fit people, but either extreme is worth attention if it comes with symptoms such as dizziness, fainting, chest pain, shortness of breath, or palpitations. A sudden, sustained change from your usual baseline also warrants a check. Persistent or symptomatic changes should be evaluated by a doctor.
How do I lower my resting heart rate?
The most effective way to lower resting heart rate over time is regular aerobic exercise, which strengthens the heart so it pumps more blood per beat and beats less often at rest. Managing stress, getting consistent sleep, staying hydrated, and limiting caffeine, alcohol, and nicotine also help. Changes are gradual, appearing over weeks to months of consistent habits. If your resting heart rate is high despite good habits, it is worth discussing with a clinician.
How do I measure my resting heart rate accurately?
Measure it first thing in the morning, before getting up and before caffeine, when you have been awake but resting quietly. Find your pulse at your wrist below the thumb or at the side of your neck, count the beats for 60 seconds, or for 30 seconds and double it. Averaging several mornings gives a more reliable number than a single reading. Wearables that track overnight heart rate are another convenient and consistent way to follow your baseline over time.
