The average resting heart rate for adults falls between 60 and 100 beats per minute (bpm). Most healthy adults land somewhere in the 70 to 80 bpm range when sitting quietly, though your specific number depends on your age, sex, fitness level, and even whether you’re awake or asleep.
Normal Resting Heart Rate for Adults
A resting heart rate is measured when you’ve been sitting or lying down calmly for at least five minutes, without recent exercise, caffeine, or stress. The standard clinical range is 60 to 100 bpm. Falling within that window is considered normal, but where you sit inside it can tell you something about your cardiovascular fitness.
Highly trained endurance athletes often have resting heart rates around 40 to 50 bpm. Their hearts pump more blood per beat, so fewer beats are needed to circulate the same volume. For the average person, a resting rate in the 60s or low 70s generally reflects good cardiovascular health, while consistently sitting near 100 bpm at rest may warrant a closer look with your doctor.
A resting heart rate consistently below 60 bpm is technically classified as bradycardia, and one above 100 bpm is classified as tachycardia. Neither label automatically means something is wrong. A fit person with a heart rate of 55 is perfectly healthy. But if a slow or fast rate comes with dizziness, fainting, shortness of breath, or chest discomfort, that’s a different story.
Differences Between Men and Women
Women tend to have slightly faster resting heart rates than men. The average adult male heart rate falls between 70 and 72 bpm, while women typically range from 78 to 82 bpm. The gap comes down to heart size: a smaller heart pumps less blood per beat, so it compensates by beating more frequently. Women also appear to have a slightly different intrinsic rhythm in their heart’s natural pacemaker, which contributes to the faster rate. If you’re a woman comparing your resting rate to a chart that doesn’t account for sex, keep this natural difference in mind.
Heart Rate by Age: Infants Through Adults
Children’s hearts beat significantly faster than adults’, and the younger the child, the faster the rate. Here’s what’s considered normal across age groups:
- Newborn to 3 months: 85 to 205 bpm while awake, 80 to 160 bpm while sleeping
- 3 months to 2 years: 100 to 190 bpm while awake, 75 to 160 bpm while sleeping
- 2 to 10 years: 60 to 140 bpm while awake, 60 to 90 bpm while sleeping
- Over 10 years: 60 to 100 bpm while awake, 50 to 90 bpm while sleeping
A newborn’s heart rate of 160 bpm would be alarming in an adult, but it’s completely normal for an infant. As children grow and their hearts get larger and stronger, the rate gradually slows until it reaches the adult range around age 10.
How Your Heart Rate Changes During Sleep
Your heart rate drops while you sleep, typically running about 20% to 30% lower than your daytime resting rate. For most healthy adults, that means a sleeping heart rate of roughly 50 to 75 bpm. During deep sleep, your heart slows the most as your body enters a restorative state with lower blood pressure and reduced demand on your cardiovascular system. During REM sleep (when dreaming occurs), your heart rate picks back up and can fluctuate more, sometimes approaching waking levels.
If you wear a fitness tracker to bed, don’t be alarmed by dips into the 40s or low 50s overnight. That’s your heart getting its own version of rest. What’s more concerning is a sleeping heart rate that stays elevated or spikes repeatedly, which can sometimes signal sleep apnea, stress, or other underlying issues.
Target Heart Rate During Exercise
When you’re working out, your heart rate should climb well above resting levels. The American Heart Association defines two main exercise zones based on your estimated maximum heart rate:
- Moderate intensity: 50% to 70% of your maximum heart rate
- Vigorous intensity: 70% to 85% of your maximum heart rate
The simplest way to estimate your maximum heart rate is 220 minus your age. A 40-year-old would have an estimated max of 180 bpm and a target zone of 90 to 153 bpm during exercise. A more accurate formula, developed from a large meta-analysis, is 208 minus 0.7 times your age. For that same 40-year-old, this gives a max of 180 bpm (the same in this case), but the two formulas diverge more noticeably for older adults. The standard 220-minus-age formula tends to underestimate maximum heart rate in people over 50, which can lead to exercise prescriptions that are too easy.
Here’s a quick reference for target heart rate zones by age:
- 20 years: 100 to 170 bpm
- 30 years: 95 to 162 bpm
- 40 years: 90 to 153 bpm
- 50 years: 85 to 145 bpm
- 60 years: 80 to 136 bpm
- 70 years: 75 to 128 bpm
What Can Raise or Lower Your Heart Rate
Your resting heart rate isn’t fixed. It shifts in response to a long list of factors, some temporary and some long-term. Caffeine, nicotine, stress, dehydration, and illness all push your heart rate up. So do stimulant medications and some over-the-counter decongestants. On the other side, regular aerobic exercise is the single most effective way to bring your resting heart rate down over time. People who start a consistent cardio routine often see their resting rate drop by 5 to 10 bpm within a few months.
Certain medications significantly affect heart rate as well. Blood pressure drugs like beta-blockers and calcium channel blockers are specifically designed to slow the heart, and they can push resting rates into the 50s or lower. Some non-heart medications, including certain anti-seizure drugs and mood stabilizers, can also slow heart rate as a side effect. If you take any of these, your “normal” baseline will naturally sit lower than the standard range, and your doctor should be tracking that.
Temperature matters too. Heat forces your heart to work harder to cool you down, so your rate climbs. Body position plays a role: standing raises your heart rate slightly compared to sitting or lying down. Even emotions like anxiety or excitement cause noticeable spikes, which is why accurate resting measurements require a few minutes of genuine calm first.
