A good resting heart rate for most adults falls between 60 and 100 beats per minute (bpm). Within that range, lower tends to be better, since it generally signals that your heart is pumping efficiently without working overtime. Highly trained endurance athletes often sit well below 60 bpm, sometimes in the 40s, because their hearts have adapted to move more blood with each beat.
What the Numbers Mean
The 60 to 100 bpm window is the standard reference range used by the American Heart Association, the Mayo Clinic, and the Cleveland Clinic. A reading consistently above 100 bpm at rest is called tachycardia, and a reading below 60 bpm is called bradycardia. Neither is automatically dangerous, but both deserve attention if you’re experiencing symptoms like dizziness, shortness of breath, or chest pain.
If you’re not a trained athlete and your resting heart rate regularly dips below 60, it’s worth mentioning to your doctor. For athletes, though, a low rate is typically a sign of cardiovascular fitness rather than a problem. The heart muscle grows stronger with sustained aerobic training, so it can push out more blood per beat and doesn’t need to beat as often to meet the body’s demands.
Where You Want to Be Within the Range
While anything from 60 to 100 is considered normal, a resting heart rate in the 60s or 70s is generally a marker of good cardiovascular health for the average adult. People who are sedentary or under chronic stress often land in the 80s or 90s. That’s still “normal” by clinical standards, but it can signal that your heart is working harder than it needs to. Improving your aerobic fitness, managing stress, and getting consistent sleep are the most reliable ways to nudge your resting rate downward over time.
Your Heart Rate During Sleep
Your resting heart rate and your sleeping heart rate are not the same number. When you fall asleep, your nervous system shifts into a more passive mode, and your heart rate drops roughly 20% to 30% below your daytime resting rate. For a healthy adult with a daytime resting rate of 60 to 100 bpm, a sleeping heart rate of about 50 to 75 bpm is typical.
If you use a fitness tracker or smartwatch, keep in mind that the overnight readings it records will naturally be lower than what you’d measure sitting on the couch. That’s normal. The overnight number is useful for spotting trends, like a gradual increase that might reflect poor recovery, illness, or elevated stress, but it shouldn’t be compared directly to the standard 60 to 100 range, which assumes you’re awake, sitting or lying down, and calm.
How to Measure It Accurately
Timing matters more than technique. To get a reliable reading, sit quietly for at least five minutes before checking. Don’t measure within one to two hours of exercise or a stressful event. Wait at least an hour after drinking coffee or anything with caffeine, which can temporarily spike your rate. Avoid taking the measurement after you’ve been standing for a long stretch, since that also shifts the number.
The simplest method is a manual pulse check. Place your index and middle fingers on the inside of your opposite wrist, just below the base of your thumb. You can also press lightly on the side of your neck, just below the jawbone. Count the beats for 15 seconds and multiply by four. For better accuracy, Harvard Health recommends repeating this a few times and averaging the results.
What Can Shift Your Baseline
Several factors push your resting heart rate up or down independent of fitness. Stress, poor sleep, dehydration, and illness all tend to raise it temporarily. Hormonal changes, including those during pregnancy or thyroid disorders, can move it significantly in either direction.
Certain medications also change the picture. Beta-blockers, one of the most commonly prescribed classes of heart medication, work specifically by slowing the heart rate and relaxing blood vessels. If you take one, your resting rate may sit comfortably in the 50s or even lower, and that’s the intended effect rather than a cause for concern. On the other end, stimulant medications, decongestants, and some asthma inhalers can push the rate higher.
Because so many variables are involved, a single reading doesn’t tell you much. The real value comes from tracking your resting heart rate over weeks and months. A gradual downward trend usually reflects improving fitness. A sudden or sustained jump, especially paired with fatigue or other symptoms, is worth investigating. The number itself is less important than the pattern.
