A regular resting heart rate for adults falls between 60 and 100 beats per minute (bpm). That range applies when you’re sitting quietly, not after exercise or a stressful moment. Where you land within that window depends on your fitness level, age, medications, and other factors, but anything in that range is generally considered normal.
Resting Heart Rate for Adults
The 60 to 100 bpm range is the standard benchmark used in clinical medicine. A heart rate below 60 bpm is called bradycardia (slow heart), and above 100 bpm is called tachycardia (fast heart). Neither is automatically dangerous. Highly fit athletes often have resting heart rates closer to 40 bpm because their hearts pump more blood with each beat, so the heart doesn’t need to beat as often to keep up with the body’s demands.
For most people who aren’t elite athletes, a resting heart rate in the 60 to 80 range is a sign of good cardiovascular health. A rate that creeps consistently toward the upper end of the range, especially above 90 bpm at rest, may be worth paying attention to over time.
Normal Heart Rate by Age
Children and infants have significantly faster heart rates than adults. Their hearts are smaller and need to beat more frequently to circulate enough blood. Here’s what’s considered normal at different ages, based on data from the U.S. Department of Health and Human Services:
- Newborn to 3 months: 85 to 205 bpm awake, 80 to 160 bpm asleep
- 3 months to 2 years: 100 to 190 bpm awake, 75 to 160 bpm asleep
- 2 to 10 years: 60 to 140 bpm awake, 60 to 90 bpm asleep
- Over 10 years: 60 to 100 bpm awake, 50 to 90 bpm asleep
By the time a child reaches their teens, their resting heart rate settles into the same 60 to 100 bpm adult range. It’s also normal for heart rate to drop during sleep at every age.
What Affects Your Resting Heart Rate
Your resting bpm isn’t a fixed number. It shifts throughout the day and from one week to the next. Fitness is the biggest long-term factor: regular aerobic exercise strengthens the heart muscle so it can pump more blood per beat, which lowers resting heart rate over months of training.
Caffeine has a measurable effect as well. Research published by the American College of Cardiology found that chronic caffeine consumption above 400 mg per day (roughly four cups of coffee) significantly raises resting heart rate and blood pressure over time. People consuming more than 600 mg daily had elevated heart rates that persisted even after resting from physical activity.
Other common factors that push your heart rate up or down include stress and anxiety, dehydration, fever, hot or cold environments, certain medications (especially beta-blockers, which lower heart rate, and decongestants, which raise it), body position (standing vs. lying down), and nicotine. Even digesting a large meal can temporarily increase your bpm by a few beats.
How to Check Your Heart Rate
The simplest way to measure your bpm is at your wrist. Place the tips of your index and middle fingers on the inside of your opposite wrist, on the thumb side, in the groove between the bone and the tendon. You should feel a pulse. Count the beats for 60 seconds, or count for 15 seconds and multiply by four.
You can also check at your neck by pressing two fingertips gently into the groove beside your windpipe. Don’t use your thumb for either method, since it has its own pulse that can throw off your count. For the most accurate resting measurement, sit still for at least five minutes beforehand.
Smartwatches and fitness trackers use optical sensors to estimate heart rate continuously. They’re reasonably accurate for resting measurements, though they can be less reliable during intense exercise or if the band is loose.
Heart Rate During Exercise
Your heart rate is supposed to climb during physical activity. The question is how high it should go. The traditional formula for estimating your maximum heart rate is 220 minus your age, but a large meta-analysis published in the Journal of the American College of Cardiology found a more accurate equation: 208 minus 0.7 times your age. For a 30-year-old, that’s a max of about 187 bpm rather than the 190 the old formula predicts. The gap grows with age: at 60, the updated formula gives 166 bpm compared to the old formula’s 160.
Moderate-intensity exercise typically puts you at 50 to 70 percent of your estimated max. Vigorous exercise pushes you to 70 to 85 percent. If math isn’t your thing during a workout, a simpler gauge works well: you should be breathing harder than normal but still able to hold a conversation during moderate exercise. If you can only get out a few words between breaths, you’re in the vigorous zone.
Signs Your Heart Rate May Be Irregular
A heart rate that’s simply fast or slow is different from one that’s irregular in its rhythm. An irregular heartbeat, called an arrhythmia, means the electrical signals that coordinate your heartbeat aren’t firing properly. You might feel a fluttering or pounding sensation in your chest, or notice that your heart seems to skip beats.
Other symptoms that can accompany an irregular rhythm include lightheadedness, dizziness, unusual fatigue, sweating, anxiety, and feeling faint. Many arrhythmias are harmless. Occasional skipped beats happen to nearly everyone and are usually triggered by caffeine, stress, or poor sleep. But a pattern of symptoms, especially chest pain, shortness of breath, or fainting, signals something that needs medical evaluation promptly.
If you’re checking your pulse manually and the beats feel unevenly spaced rather than steady, that’s worth noting and mentioning to a doctor, even if the rate itself falls within the normal range.
