Your heart beats around 100,000 times a day, and most of the time you don't notice it. But the speed of those beats when you're calm and still, your resting heart rate, is one of the simplest health numbers you can track. It costs nothing, takes less than a minute, and can tell you a surprising amount about your fitness and overall health.
This guide explains what counts as a normal resting heart rate, how to measure yours accurately, what can push it up or down, and when a reading deserves a conversation with your doctor.
Quick answer: A normal resting heart rate for adults is 60 to 100 beats per minute (bpm). A lower rate usually means a fitter heart; very fit athletes may be closer to 40 bpm. See a doctor if your resting rate is regularly above 100 bpm, or below 60 bpm if you're not an athlete, especially with dizziness, fainting, or shortness of breath.

What Is Resting Heart Rate?
Your resting heart rate is the number of times your heart beats per minute when you are awake, calm, and not moving. It reflects how hard your heart has to work to pump blood around your body when no extra demand is placed on it.
It is not the same as blood pressure. Heart rate measures how fast your heart beats. Blood pressure measures the force of blood against your artery walls. One can be normal while the other is not, so they need to be checked separately.
What Is a Normal Resting Heart Rate?
According to the American Heart Association, a normal resting heart rate for adults is between 60 and 100 beats per minute.
| Resting heart rate | What it usually means |
|---|---|
| Around 40 to 60 bpm | Common in very fit people and athletes; can also be caused by some medications. Worth checking if you're not athletic. |
| 60 to 100 bpm | Normal range for adults |
| Regularly above 100 bpm | Higher than normal at rest; talk to your doctor |
Within the normal range, there is still a lot of variation. Harvard Health Publishing notes that most healthy adults fall between about 55 and 85 bpm, and that a resting rate consistently above 90 is worth mentioning to your doctor.
What a Lower Resting Heart Rate Says About Your Fitness
In general, a lower resting heart rate points to a more efficient heart. A strong heart muscle pushes out more blood with each beat, so it doesn't need to beat as often.
The Mayo Clinic notes that a very fit athlete may have a resting heart rate closer to 40 beats per minute. For that person, a low number is a sign of excellent conditioning, not a problem.
Context matters, though. A low heart rate in someone who is not physically active, particularly when it comes with tiredness, dizziness, or fainting, may point to a problem with the heart's electrical system or a side effect of medication.
What Can Affect Your Resting Heart Rate
Your heart rate changes from day to day, and even hour to hour. According to the American Heart Association and the Mayo Clinic, these factors influence it:
- Age and fitness level: regular aerobic exercise lowers resting heart rate over time.
- Emotions: stress, anxiety, and excitement raise it.
- Sleep: poor or short sleep can push it higher the next day.
- Temperature: hot, humid weather makes the heart beat faster.
- Body position: your pulse may rise slightly for a short time after you stand up.
- Body size: obesity is associated with a higher resting rate.
- Smoking: smokers tend to have higher resting heart rates.
- Medications: beta blockers and calcium channel blockers slow the heart rate; some other medicines speed it up.
- Health conditions: heart disease, diabetes, and other medical conditions can change it.
Caffeine, dehydration, fever, and illness can also raise your pulse temporarily. That's why a single reading means little. The pattern over days and weeks is what counts.
How to Measure Your Resting Heart Rate
You don't need a device. Two fingers and a clock are enough.
- Choose the right moment. Harvard Health suggests first thing in the morning, before you get out of bed. Otherwise, sit quietly for at least five minutes first. Avoid measuring right after exercise, caffeine, or a stressful event.
- Find your pulse. Place your index and middle fingers on the inside of your wrist, just below the base of the thumb. You can also use the side of your neck, next to your windpipe.
- Count the beats. Count for 30 seconds and multiply by two, or count for a full 60 seconds for the most accurate result.
- Repeat over several days. Take a reading at the same time for a week and note the average.
Smartwatches and fitness trackers make this easier by tracking your resting heart rate automatically. The Mayo Clinic notes that accuracy varies between devices, so use them to follow trends and confirm any unusual reading by hand.
When to See a Doctor
Contact your healthcare provider if:
- your resting heart rate is regularly above 100 bpm (called tachycardia)
- your resting heart rate is below 60 bpm and you are not an athlete (called bradycardia), especially if you feel tired, weak, or dizzy
- your usual resting rate changes noticeably and stays changed without an obvious reason
- your pulse feels irregular, with skipped or extra beats that keep happening
Call your local emergency number immediately if a very fast, very slow, or irregular heartbeat comes with chest pain, shortness of breath, or fainting.
How to Lower Your Resting Heart Rate Naturally
If your resting heart rate is at the higher end of normal, healthy habits can bring it down gradually over weeks and months.
- Do regular aerobic exercise. Brisk walking, cycling, and swimming strengthen the heart. Harvard Health describes exercise as the best way to lower your resting heart rate. If you're new to exercise, start with our guide on how many steps a day you really need.
- Manage stress. Slow breathing, time outdoors, and relaxation techniques calm the nervous system. See these stress management techniques backed by research.
- Get enough sleep. Aim for a consistent sleep schedule.
- Stay hydrated. When you're dehydrated, your heart has to work harder.
- Cut back on stimulants. Too much caffeine and nicotine both raise heart rate.
- Work toward a healthy weight. Carrying less extra weight reduces the load on your heart.
If you take medication that affects your heart rate, such as a beta blocker, talk to your doctor before starting a new exercise program.
Frequently Asked Questions
Is a resting heart rate of 55 good?
For a physically active person with no symptoms, a resting rate in the 50s is usually a sign of good fitness. If you're not active, or you feel dizzy, weak, or faint, have it checked.
Is a resting heart rate of 90 too high?
It's within the normal range of 60 to 100 bpm. However, a rate that stays at the high end may be worth discussing with your doctor, and it often improves with regular exercise, better sleep, and less stress.
Does resting heart rate increase with age?
The normal range for adults stays the same at 60 to 100 bpm. What changes more with age is your maximum heart rate during exercise, which gradually declines.
Why is my heart rate higher some mornings?
Poor sleep, stress, alcohol the night before, dehydration, or the start of an illness can all raise it temporarily. Look at the average across a week, not a single day.
The Bottom Line
Your resting heart rate is a quick, free window into how your heart is doing. For most adults, 60 to 100 bpm is normal, and a lower number within or just below that range often reflects better fitness. Measure it for a week to learn your own baseline, watch for lasting changes, and talk to your doctor if your numbers fall outside the normal range or come with symptoms.
