A good resting heart rate (RHR) for most adults falls between 60 and 100 beats per minute, but research suggests that lower within that range is generally better. Studies have found a continuous increase in cardiovascular risk at heart rates above 60 bpm, meaning a rate in the 60s or low 70s is a strong sign of heart health for the average person.
The Normal Range and What’s Ideal
The standard medical reference range is 60 to 100 bpm. Anything consistently above 100 bpm at rest is considered tachycardia, and anything below 60 bpm is technically bradycardia. But those boundaries don’t tell the whole story. A resting heart rate of 95 bpm is “normal” by definition, yet it sits far from optimal. Research published in the Journal of the American College of Cardiology found that maintaining a resting heart rate well below the traditional upper limit of 90 or 100 bpm is desirable for long-term cardiovascular health.
For a healthy adult who exercises moderately, a resting heart rate in the 60 to 75 bpm range is a reasonable target. Trained endurance athletes commonly sit between 40 and 60 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. That kind of low rate in a fit person is a sign of efficiency, not a problem.
When a Low Heart Rate Is Normal
A resting heart rate between 40 and 60 bpm is common in healthy young adults and people who exercise regularly. It’s also typical during sleep, when your heart rate drops 20% to 30% below your waking resting rate. If your daytime RHR is 65, you might dip into the mid-40s overnight, and that’s perfectly healthy.
A low heart rate only becomes a concern when the heart can’t pump enough oxygen-rich blood to the rest of the body. Signs that a slow rate is problematic include dizziness, unusual fatigue (especially during physical activity), fainting or near-fainting, shortness of breath, confusion, and chest pain. If you’re active, feel fine, and your wearable shows a rate in the 50s, that’s typically a mark of good fitness rather than something to worry about.
What Pushes Your RHR Higher
Your resting heart rate isn’t a fixed number. It shifts throughout the day and from one day to the next based on several factors:
- Caffeine and stimulants: Coffee, energy drinks, and even some cold and cough medications contain stimulants that temporarily raise your heart rate.
- Stress and anxiety: Your body’s stress response speeds the heart up, and chronic stress can keep your resting rate elevated over time.
- Poor sleep: Adults who consistently get fewer than 7 hours tend to have higher resting rates. Aim for 7 to 9 hours.
- Alcohol: Excessive drinking raises heart rate, and alcohol withdrawal can spike it further.
- Dehydration and electrolyte imbalance: When your blood volume drops or minerals like potassium and magnesium are off balance, your heart compensates by beating faster.
- Fever and illness: Even a mild infection can temporarily push your rate up by 10 or more bpm.
If your resting heart rate seems higher than usual, check these factors before assuming something is wrong. A single elevated reading after a bad night of sleep or a stressful day isn’t meaningful. A pattern of elevated readings over weeks is worth paying attention to.
How to Measure It Accurately
The most reliable way to check your resting heart rate is first thing in the morning, before you get out of bed, after a full night of sleep. Sit or lie still for a few minutes before measuring. You can place two fingers on the inside of your wrist (just below the base of your thumb) or on the side of your neck, count the beats for 30 seconds, and double that number. Do this on several different mornings to get a consistent baseline rather than relying on a single reading.
Checking after exercise, caffeine, or a stressful event will give you an artificially high number. The goal is to capture what your heart does when your body has no particular demands on it.
How Accurate Are Wearables?
Most people now track their resting heart rate through a smartwatch or fitness band rather than checking their pulse manually. These devices use optical sensors that shine light into your skin and measure blood flow, and their accuracy varies more than you might expect.
A validation study testing 10 popular wearables found that the Fitbit Charge 6 and Google Pixel Watch 2 performed best, with average errors of about 4.5 to 5 bpm and strong agreement with medical-grade monitors. The Garmin Vivoactive 5 and Apple Watch SE also showed reasonable accuracy, with average errors of about 5 bpm. On the other end, the Oura Ring (Gen 3), Fitbit Inspire 3, and several Polar models had average errors of 9 to 14 bpm, which is large enough to make a reading of 68 actually be anywhere from 54 to 82.
Movement makes things worse. Walking intermittently during testing increased errors across multiple devices. For the most accurate wearable readings, check the heart rate your device logs overnight or during quiet, still moments. Climate and temperature didn’t meaningfully affect accuracy in testing, so you don’t need to worry about that variable.
If your wearable consistently shows a resting rate that seems unusually high or low, cross-check it with a manual pulse count a few times before drawing conclusions.
How to Lower Your Resting Heart Rate
Regular aerobic exercise is the single most effective way to bring your resting heart rate down. When you run, swim, cycle, or do other sustained cardio, your heart muscle gets stronger and pumps more blood per beat. Over weeks and months, this means your heart doesn’t need to beat as often at rest to move the same volume of blood. Even moderate activity, like brisk walking for 30 minutes most days, can lower your resting rate by several beats per minute over time.
Beyond exercise, managing stress through consistent sleep, reducing excessive caffeine and alcohol intake, staying hydrated, and maintaining a healthy weight all contribute to a lower resting rate. These aren’t dramatic interventions, but their effects compound. Someone who sleeps well, moves regularly, and manages stress will typically see their resting heart rate settle into a healthier range within a few months.
Tracking your RHR over time is more useful than fixating on any single number. A gradual downward trend as you get fitter, or a sudden upward shift that lasts more than a few days, tells you something meaningful about what’s happening in your body. The trend is the signal.
