A normal resting pulse rate for adults falls between 60 and 100 beats per minute (bpm), according to the American Heart Association. That said, the average adult rests closer to 72 or 73 bpm, and your ideal number depends on your age, fitness level, and what you’re doing at the time.
Normal Resting Pulse by Age
Heart rate naturally slows as you grow from infancy into adulthood, then stays remarkably stable for the rest of your life. National survey data covering nearly a decade of measurements shows these averages:
- Under 1 year: 129 bpm
- 1 year: 118 bpm
- 2 to 3 years: 107 bpm
- 4 to 5 years: 96 bpm
- 6 to 8 years: 87 bpm
- 9 to 11 years: 83 bpm
- 12 to 15 years: 78 bpm
- 16 to 19 years: 75 bpm
- 20 to 39 years: 73 bpm
- 40 to 59 years: 72 bpm
- 60 to 79 years: 72 bpm
- 80 and older: 72 bpm
Once you reach your early 20s, the average barely changes. Adults in their 30s, 50s, and 70s all cluster around 72 to 73 bpm. Individual variation is wide, though, so a resting rate of 65 or 80 is perfectly normal for most people.
Your Pulse During Sleep
Your heart slows down at night, especially during deep sleep stages when blood pressure also dips. A healthy adult typically runs between 50 and 75 bpm while sleeping. If you wear a fitness tracker and notice overnight readings in the low 50s, that’s generally normal and not a sign of a problem.
Why Athletes Have Much Lower Rates
Endurance training physically remodels the heart’s pacemaker cells, making the heart pump more blood per beat and reducing how often it needs to beat at rest. Up to 80% of endurance athletes develop a resting heart rate below 60 bpm. In a study of 465 endurance athletes, 38% had a minimum heart rate at or below 40 bpm on a 24-hour monitor, and those rates were well tolerated with no symptoms.
A small number (about 2%) dropped to 30 bpm or below, which is considered extreme. So if you run, cycle, or swim regularly and your resting pulse sits in the 40s or 50s, that’s likely a sign of cardiovascular fitness rather than a medical concern.
When Your Pulse Is Too Fast or Too Slow
A resting rate consistently above 100 bpm is called tachycardia. A rate below 60 bpm is called bradycardia. These are clinical thresholds, not automatic emergencies. Many healthy people (especially fit ones) live comfortably below 60 bpm, and your heart rate can temporarily spike above 100 from caffeine, stress, or standing up quickly.
The numbers matter more when symptoms come along with them. Signs that your heart rate is causing a problem include dizziness or lightheadedness, fainting or near-fainting, unusual fatigue during physical activity, shortness of breath, chest pain, and confusion or memory trouble. A pulse that stays elevated at rest without an obvious trigger, or one that drops low enough to make you feel faint, is worth getting checked.
What Affects Your Pulse Day to Day
Your resting heart rate isn’t a fixed number. It shifts throughout the day based on several factors. Stress and anxiety raise it by triggering your body’s fight-or-flight hormones. Dehydration forces the heart to beat faster to maintain blood pressure. Fever increases your pulse by roughly 10 bpm for every degree above normal body temperature. Hot weather and high humidity can push it higher too.
Certain medications also have a direct effect. Beta-blockers, one of the most commonly prescribed heart medications, work specifically by slowing your heart rate and relaxing blood vessels. If you take one, a resting pulse in the 50s or even high 40s may be your expected baseline. Stimulant medications, decongestants, and thyroid hormones can push your pulse in the other direction.
Caffeine is widely believed to raise heart rate, but the evidence is more nuanced. Research on trained cyclists given a moderate caffeine dose found no significant change in heart rate at rest or during exercise. Caffeine did raise blood pressure, though, so the effect you feel after coffee may be more about blood pressure and alertness than a faster pulse.
Target Pulse During Exercise
When you’re working out, your pulse should go well above resting. The general framework uses a percentage of your estimated maximum heart rate, which you can calculate by subtracting your age from 220. A 40-year-old, for example, would have an estimated max of 180 bpm.
- Moderate intensity (brisk walking, easy cycling): 50% to 70% of your max
- Vigorous intensity (running, high-effort cycling): 70% to 85% of your max
For that 40-year-old, moderate exercise means a heart rate of roughly 90 to 126 bpm, and vigorous exercise means 126 to 153 bpm.
The “220 minus age” formula is the most widely known, but it’s an estimate with a margin of error around 7 to 10 bpm in either direction. Researchers have tested several alternative formulas, and while some (like 208 minus 0.7 times your age) perform slightly better on average, none are highly precise for any individual. Use these numbers as a guideline, not a hard rule. If you can carry on a conversation but feel like you’re working, you’re likely in the moderate zone. If talking becomes difficult, you’ve crossed into vigorous territory.
How to Check Your Pulse
Sit quietly for a few minutes before measuring. The two easiest spots are your wrist and your neck.
For a wrist (radial) pulse, turn your hand palm-up and place the tips of your index and middle fingers between the wrist bone and the tendon on the thumb side. Press lightly until you feel each beat. Pressing too hard can actually block blood flow and make the pulse harder to detect.
For a neck (carotid) pulse, place the same two fingertips in the groove beside your windpipe on one side. Never press both sides of your neck at once, as this can cause dizziness or fainting.
Count beats for a full 60 seconds for the most accurate reading. A shortcut is to count for 15 seconds and multiply by four, but this amplifies any counting error. If you want to track trends over time, measure at the same time of day under the same conditions, ideally first thing in the morning before getting out of bed.
