A normal resting heart rate for adults falls between 60 and 100 beats per minute (BPM). That range applies when you’re sitting or lying down calmly, not right after exercise or a stressful event. Where you land within that window depends on your fitness level, age, medications, and other factors, so there’s no single “perfect” number.
Normal Ranges by Age
Heart rate ranges shift dramatically from birth through adolescence. Newborns have the fastest hearts, and the rate gradually slows as children grow. Here are the typical awake ranges by age group:
- 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 and adults: 60 to 100 BPM
Children’s heart rates also drop significantly during sleep. A child between 2 and 10 years old, for example, typically falls to 60 to 90 BPM while sleeping. By the time a person reaches about age 10, their resting heart rate settles into the same 60 to 100 BPM range that applies for the rest of adulthood.
Why Athletes Often Have Lower Rates
Endurance athletes and people who exercise regularly often have resting heart rates well below 60 BPM, sometimes in the 40s. This happens because consistent aerobic training strengthens the heart muscle, allowing it to pump more blood with each beat. A stronger heart doesn’t need to beat as often to deliver the same amount of oxygen to the body.
A rate below 60 BPM in a trained athlete is generally a sign of cardiovascular fitness, not a problem. However, if you’re not particularly active and your resting heart rate regularly sits below 60, that’s worth mentioning to a doctor, since it could signal an issue with the heart’s electrical system.
Your Heart Rate During Sleep
Your heart doesn’t beat at the same speed around the clock. During deep sleep, your heart rate typically drops 20% to 30% below your normal resting rate. For someone with a daytime resting rate of 70 BPM, that means the heart might slow to roughly 49 to 56 BPM overnight. This dip is completely normal and reflects your body’s reduced demand for oxygen while at rest. If you wear a fitness tracker, you’ll often notice your lowest recorded heart rate comes from the middle of the night.
What Pushes Your Heart Rate Up or Down
Plenty of everyday factors shift your resting heart rate temporarily. Caffeine, stress, anxiety, dehydration, and hot weather all tend to push it higher. Certain medications, particularly beta-blockers and some blood pressure drugs, bring it down. Illness and fever raise it because your body is working harder to fight infection. Even body position matters: your heart rate is slightly higher when standing than when sitting or lying down.
Over longer time frames, consistent exercise is the most reliable way to lower your resting rate. Weight gain, poor sleep, and chronic stress tend to raise it. Tracking your resting heart rate over weeks or months can reveal trends in your overall cardiovascular fitness more clearly than any single reading.
Heart Rate During Exercise
When you’re working out, your heart rate should climb well above that resting range. A simple formula gives you a rough ceiling: subtract your age from 220 to estimate your maximum heart rate. A 40-year-old, for example, has an estimated max of about 180 BPM.
From there, exercise intensity breaks into two useful zones. Moderate-intensity activity (a brisk walk, casual cycling) puts you at 50% to 70% of your max. Vigorous activity (running, high-intensity intervals) pushes you to 70% to 85% of your max. For that same 40-year-old, moderate intensity means roughly 90 to 126 BPM, while vigorous means about 126 to 153 BPM. These zones help you gauge effort if you’re using a heart rate monitor during workouts.
How to Check Your Pulse
You don’t need any equipment to measure your heart rate. Sit down and rest quietly for a few minutes first, then use the tips of your index and middle fingers (not your thumb, which has its own pulse) to find a pulse point.
The easiest spot is your wrist. Turn one hand palm-up and press lightly on the thumb side of your wrist, in the groove between the bone and the tendon. You can also check at your neck by placing two fingers in the soft groove next to your windpipe. Press gently. Pushing too hard can actually block blood flow and give you an inaccurate count. If you check at the neck, only press on one side at a time, since pressing both sides simultaneously can cause dizziness or fainting.
Count the beats for a full 60 seconds for the most accurate reading. A quicker method is to count for 15 seconds and multiply by four, though this is slightly less precise. The number you get is your resting heart rate in BPM.
When a Heart Rate Signals a Problem
A resting heart rate consistently above 100 BPM is called tachycardia. A rate consistently below 60 BPM (in someone who isn’t athletic) is called bradycardia. Neither is necessarily dangerous on its own, but both can indicate an underlying rhythm issue that needs evaluation.
The heart rate itself matters less than how you feel. An irregular heartbeat, a rate that seems to jump or skip, or a pulse that races without an obvious trigger (like exercise or caffeine) are all worth paying attention to. The symptoms that call for emergency care are chest pain, shortness of breath, and fainting. A dangerous rhythm called ventricular fibrillation can cause a sudden drop in blood pressure, collapse, and loss of pulse within seconds. That scenario requires immediate emergency help.
For most people, though, checking your resting heart rate is simply a quick, free snapshot of cardiovascular health. A rate that stays in the lower half of the 60 to 100 range, especially if it trends downward as you get fitter, is a good sign that your heart is working efficiently.
