A normal resting heart rate for adults falls between 60 and 100 beats per minute. That range applies when you’re sitting quietly, not after exercise or a stressful moment. Where you land within it depends on your age, fitness level, medications, and several other factors.
Resting Heart Rate for Adults
The 60 to 100 bpm window is the standard reference range used in clinical medicine. Most healthy adults who don’t exercise intensely will sit somewhere in the middle of that range, typically between 70 and 85 bpm. A rate consistently at the lower end often signals good cardiovascular fitness, since a stronger heart pumps more blood per beat and doesn’t need to work as hard at rest.
Well-trained endurance athletes routinely have resting rates between 40 and 60 bpm. Elite cyclists and rowers have been recorded as low as 30 bpm, and some elite athletes dip below 30 during deep sleep. These numbers would be alarming in a sedentary person but are a normal adaptation to years of aerobic training.
Normal Ranges for Children
Children’s hearts beat faster than adults’, and the younger the child, the higher the rate. Here’s what’s typical when a child is awake:
- Newborn to 3 months: 85 to 205 bpm
- 3 months to 2 years: 100 to 190 bpm
- 2 to 10 years: 60 to 140 bpm
- Over 10 years: 60 to 100 bpm (essentially the adult range)
During sleep, children’s rates drop considerably. A sleeping toddler might run 75 to 160 bpm, while a sleeping school-age child typically falls between 60 and 90 bpm.
What Happens During Sleep
Your heart rate drops about 20% to 30% below your daytime resting rate while you sleep. For most adults, that puts the normal sleeping range at roughly 50 to 75 bpm. Rates as low as 40 bpm during sleep can still be normal, especially if you’re physically active. A sleeping heart rate outside the 40 to 100 bpm range is generally considered worth investigating.
If you use a wearable tracker, your overnight heart rate data can be one of the most consistent measurements you have, since sleep removes the variables of movement, caffeine, and stress. A sudden upward trend in your sleeping rate over several nights can sometimes signal an oncoming illness or accumulated fatigue.
When Your Rate Is Too High or Too Low
Clinically, a resting heart rate above 100 bpm is called tachycardia, and a rate below 60 bpm is called bradycardia. Neither label automatically means something is wrong. A nervous patient in a doctor’s office can easily hit 105, and a fit runner sitting at 55 is perfectly healthy.
Context matters more than the number alone. A resting rate above 100 that persists when you’re calm, well-hydrated, and haven’t had caffeine is more meaningful than a one-time reading. The same goes for a low rate: if you feel fine and aren’t dizzy, a rate in the 50s is rarely a concern. Symptoms like lightheadedness, fainting, chest discomfort, or unusual shortness of breath alongside an abnormal rate are what shift a number from “variant of normal” to “worth checking out.”
What Affects Your Resting Rate
Your resting heart rate isn’t fixed. It shifts throughout the day and across your lifespan. The major influences include:
- Fitness level: Regular aerobic exercise lowers your resting rate over time by making the heart more efficient.
- Age: Resting rate tends to rise slightly with age in sedentary adults, though staying active can offset this.
- Medications: Beta blockers and calcium channel blockers, commonly prescribed for blood pressure and heart conditions, can lower your rate significantly. Some non-heart medications, including certain mood stabilizers and anti-seizure drugs, can also slow the heart. On the other side, decongestants and stimulant medications can push it higher.
- Emotions and stress: Anxiety, excitement, and even body posture (standing vs. lying down) cause short-term fluctuations.
- Smoking and alcohol: Both tend to elevate resting heart rate.
- Body temperature and illness: A fever raises your rate by roughly 10 bpm for every degree above normal.
How to Measure Your Resting Heart Rate
The best time to check is first thing in the morning, before you get out of bed or reach for coffee. Place two fingers (index and middle, not your thumb) on the inside of your wrist just below the base of your thumb, or on the side of your neck beside your windpipe. Count the beats for 30 seconds and multiply by two. If your rhythm feels irregular, count for a full 60 seconds for better accuracy.
Taking this measurement on several consecutive mornings and averaging the results gives you a more reliable baseline than any single reading. Wearable devices do this automatically, though optical wrist sensors can be less accurate during movement or on darker skin tones. A manual check is a good way to verify what your tracker reports.
Heart Rate During Exercise
When you’re working out, your heart rate should climb well above resting. The general target zones are based on a percentage of your estimated maximum heart rate:
- Moderate intensity (brisk walking, easy cycling): 50% to 70% of your max
- Vigorous intensity (running, intense cycling): 70% to 85% of your max
The most common formula for estimating your maximum heart rate is simply 220 minus your age. A 40-year-old, for example, would get a max of 180 bpm, putting moderate exercise in the 90 to 126 range and vigorous exercise at 126 to 153. This formula, first proposed in 1971, has a margin of error of 10 to 12 bpm in either direction. It tends to overestimate max heart rate in younger adults and underestimate it in older adults. Researchers have tested at least nine alternative formulas, and none consistently outperform the original for the general population. Treat it as a rough guide, not a precise ceiling.
Heart Rate Recovery After Exercise
How quickly your heart rate drops after you stop exercising is itself a useful health marker. A healthy recovery is a drop of at least 18 beats within the first minute of rest. A sluggish recovery, where your rate stays elevated longer, is associated with lower cardiovascular fitness and, in clinical settings, has been linked to higher long-term cardiac risk.
You can track this easily: note your heart rate the moment you stop a hard effort, then check again after 60 seconds of standing or walking slowly. Over weeks and months of consistent training, you should see that one-minute drop improve, which is a practical sign that your heart is getting more efficient.
