Is 89 BPM Good? What Your Resting Heart Rate Means

A resting heart rate of 89 beats per minute falls within the traditional “normal” range of 60 to 100 BPM that most doctors reference, but it sits at the higher end of that window, and a growing body of research suggests that rates above 80 BPM are associated with meaningfully higher health risks over time. The 60-to-100 range is more of a rough clinical boundary than a stamp of approval, and where you land within it matters more than most people realize.

Why the 60 to 100 Range Is Misleading

The 60-to-100 BPM range dates back decades and was designed mainly to help clinicians flag obvious abnormalities. A rate below 60 gets labeled bradycardia; above 100, tachycardia. The range was never meant to say “anywhere in here is equally healthy.” It is a screening fence, not a wellness score. Many fit, healthy adults have resting rates in the 50s or even high 40s. Meanwhile, someone sitting at 95 BPM technically passes the “normal” test but may have a cardiovascular system working harder than it should at rest.

If you have been told your heart rate of 89 is “fine” because it is under 100, that is technically accurate in the sense that it does not qualify as tachycardia. But it does not mean the number is ideal. The evidence increasingly points to lower resting rates being associated with better outcomes, and the most relevant question is not whether 89 is abnormal but what it tells you about your body and what, if anything, you can do about it.

What the Mortality Data Actually Shows

Two large meta-analyses offer a fairly clear picture of the relationship between resting heart rate and long-term health. One, pooling data from dozens of prospective studies, found that each increase of 10 BPM in resting heart rate was associated with roughly a 17% higher risk of dying from any cause and a 15% higher risk of cardiovascular disease.¹ Another meta-analysis, looking specifically at all-cause and cardiovascular mortality, found that people with resting heart rates above 80 BPM had about a 45% higher relative risk of all-cause mortality and a 33% higher relative risk of cardiovascular mortality compared to those in the lowest heart-rate category.²

Those are relative risks, not absolute ones, and they reflect population-level trends across many thousands of people followed for years. A resting rate of 89 does not mean you are in danger tomorrow. But it does place you in a statistical neighborhood where the risk curves start climbing. For context, people in the 60-to-80 range in that same meta-analysis had a much more modest increase in risk compared to the lowest-rate group.² The relationship follows a dose-response pattern: higher rate, higher risk, with no obvious “safe” threshold below which the relationship disappears.

One caveat worth noting: these studies measure association, not pure causation. A faster resting heart rate might partly be a marker for other things going on in the body, like low fitness, chronic stress, or metabolic problems, rather than the direct cause of harm. Still, the consistency of findings across many populations and study designs means it is worth paying attention to.

What Determines Your Resting Heart Rate

Resting heart rate is not a single fixed number controlled by one thing. It reflects a tug-of-war between the two branches of your autonomic nervous system. The parasympathetic branch, acting mainly through the vagus nerve, slows your heart down. The sympathetic branch speeds it up. At rest, a healthy body leans toward parasympathetic dominance, which is why a lower resting rate generally signals that your nervous system is doing its job well.³ When vagal tone is strong, the brake pedal is firmly pressed and your heart can afford to pump slowly because each beat is efficient.

Fitness is the single most modifiable factor. Regular aerobic exercise increases the volume of blood your heart can pump per beat, so it does not need to beat as often to deliver the same amount of oxygen. A classic training study showed that after two months of hard exercise, participants had larger stroke volumes and lower resting heart rates, and the improvement was even more dramatic during physical effort.⁴ This is why endurance athletes routinely sit in the 40s or 50s.

Beyond fitness, a number of other factors push the number around:

Acute stress and anxiety: Psychological stress triggers sympathetic activation, which raises heart rate. If you checked your pulse during a stressful moment or in a doctor’s office (the classic “white coat” effect), your reading may be artificially high.⁵
Caffeine, alcohol, and nicotine: Caffeine tends to raise heart rate modestly, and the combination of stimulants can prevent the normal decline you would see during a relaxed rest period.⁶
Fever and illness: During infection, heart rate rises with body temperature. In children, each one-degree-Celsius increase in temperature corresponds to a heart rate increase of roughly 8 to 14 BPM, depending on age.⁷ The same general principle applies in adults, though the magnitude is typically smaller.
Altitude: Moving to high elevation triggers sympathetic nervous system activation due to lower oxygen levels. Heart rate rises initially, though this effect can diminish over days as the body acclimatizes.⁸
Medications: Beta-blockers lower resting heart rate by design. Decongestants, some asthma medications, and thyroid hormone replacements can push it up. If you are on any of these, your resting rate reflects the drug as much as your baseline physiology.

So if you measured 89 BPM after a morning coffee, in a doctor’s waiting room, or while fighting a mild cold, the number may not represent your true resting state. The most reliable reading comes after sitting or lying quietly for several minutes, ideally first thing in the morning before caffeine or significant activity.

How Sex and Age Shift the Baseline

Women tend to have higher resting heart rates than men. In one study of a rural adult population, women averaged about 82 BPM compared to roughly 70 BPM for men.⁹ Research on heart rate variability confirms this pattern: women up to about age 55 show higher resting rates compared to men of the same age.¹⁰ The difference likely relates to body size, hormonal influences on the autonomic nervous system, and differences in cardiac chamber size and stroke volume. A smaller heart pumps less blood per beat and needs to beat faster to compensate.

This means an 89 BPM reading carries different context for a woman than for a man. For a woman in her 30s or 40s, 89 is above average but not dramatically so. For a man of similar age and fitness level, it would sit further above the typical range and might warrant a closer look at lifestyle factors or a conversation with a doctor.

Age also plays a role, though the relationship is less straightforward than people assume. Resting heart rate does not uniformly climb with age. What changes more clearly is heart rate variability, the beat-to-beat fluctuation in timing that reflects how flexibly the nervous system is regulating the heart. Variability tends to decline with age in both sexes, meaning the heart becomes less adaptable even if the average rate stays roughly similar.¹⁰ Vagal tone, the parasympathetic “braking” influence that keeps resting rate low, is tied to self-regulation across cognitive, emotional, and health domains, and its decline with age is one of the reasons older adults are more vulnerable to cardiovascular problems.¹¹

Your Genes Set Part of the Range

Not everything about your resting heart rate is under your control. A massive genome-wide analysis of over 835,000 people identified 493 independent genetic variants across 352 locations in the genome that influence resting heart rate.¹² Earlier work had already identified at least 21 heart-rate-associated genetic regions, and the list keeps growing as study populations get larger.¹³

What this means practically is that some people are genetically predisposed to run a bit faster or slower at rest, independent of fitness, body composition, or stress levels. If both your parents had resting rates in the 80s and you are consistently around 89 despite being fit and healthy, genetics may explain much of the gap between you and someone whose rate sits in the 60s. That said, genes set a range, not a destiny. Exercise and lifestyle modifications still shift the number meaningfully within whatever range your DNA allows.

Can You Actually Lower It?

Yes, and exercise is the intervention with the strongest evidence. A systematic review and meta-analysis of exercise interventions found that, on average, people who exercised lowered their resting heart rate by about 3 to 4 BPM more than non-exercising control groups.¹⁴ Men in the studies saw slightly larger reductions, averaging about 4 BPM, while women averaged about 3 BPM. The effect was strongest for endurance training but also showed up for yoga, strength training, and combination programs.¹⁴

A 3-to-4 BPM drop may sound modest, but given the dose-response relationship between heart rate and mortality, even a small reduction matters over a lifetime. If you moved from 89 to 82 through consistent aerobic training, you would shift from a higher-risk bracket into a more favorable one. The reduction does not happen overnight; most training studies run for at least several weeks to a few months before the effect becomes clear, and the benefit disappears if you stop exercising.

Other habits that can help include managing chronic stress (since ongoing sympathetic activation keeps the rate elevated), getting adequate sleep, staying well hydrated, and cutting back on stimulants if you are a heavy caffeine or nicotine user. None of these have the evidence base that exercise does, but they address some of the modifiable factors listed earlier.

How Accurate Is Your Measurement?

Before worrying too much about 89 BPM, consider how you got the number. If it came from a doctor’s office visit with a pulse oximeter or manual count, it was measured after you walked in, possibly waited anxiously, and sat down in a clinical setting. That reading is unlikely to reflect your true resting baseline.

If it came from a wearable device like a fitness tracker, accuracy depends heavily on context. A validation study of the Fitbit Charge 4 found that during running, the optical heart rate sensor was very accurate, with an average error of about 1 BPM. But during activities involving a lot of wrist movement, like badminton or soccer, the average error ballooned to over 16 BPM.¹⁵ For resting measurements, wearable accuracy tends to be better since your wrist is still, but readings can still drift if the band is loose, placed over a tattoo, or taken during movement.

Smartphone apps that use the camera and flash to read your pulse through your fingertip appear to agree well with gold-standard electrocardiography in healthy people under controlled conditions.¹⁶ “Controlled conditions” is the operative phrase: sitting still, finger firmly placed, no movement. If you took a casual reading while walking around, the number is less trustworthy.

The best approach for tracking your own resting heart rate is consistency. Measure at the same time each day, ideally in the morning before getting out of bed, with the same device, in the same position. A single number matters less than a trend over weeks or months.

What Your Heart Does While You Sleep

Your resting heart rate during the day tells one story, but your sleeping heart rate and how far it drops from your waking rate tell another. Research from a large clinical population found that the magnitude of the heart rate “dip” during sleep was a remarkably strong predictor of mortality, more linear and consistent than the waking heart rate itself.¹⁷ People whose heart rate barely dropped at night, or even rose, had substantially higher mortality compared to those with a robust dip of around 25 to 30 BPM during sleep.

Many wearable devices now track overnight heart rate and display it as a nightly average or a trend graph. If your waking rate is 89 but it dips into the mid-60s during sleep, that pattern suggests your autonomic nervous system is still capable of slowing things down when it should. If it stays in the 80s all night, that is a different picture and may be worth discussing with a healthcare provider. The sleep dip reflects the body’s ability to shift into parasympathetic mode, and a blunted dip can signal underlying issues with autonomic regulation, sleep quality, or cardiovascular health.

The Mammalian Heartbeat Budget

Here is a piece of biology that puts resting heart rate in a wider frame. Across mammalian species, there is a striking inverse relationship between heart rate and lifespan. Small animals with fast heart rates live short lives; large animals with slow hearts live longer. When researchers calculated the total number of heartbeats per lifetime across species, the figure came out remarkably consistent: roughly 700 million to a billion beats per lifetime, regardless of whether you are a mouse or an elephant.¹⁸

Humans are an outlier in this picture. Thanks to modern medicine, nutrition, and sanitation, we live far longer than the allometric scaling would predict for our body size and heart rate, racking up around 2.5 to 3 billion heartbeats over a typical lifespan. Still, the underlying principle resonates: within our species, a slower resting rate tends to track with longer life. The mammalian heartbeat budget is more of an elegant observation than a causal law, but it aligns with the epidemiological data showing that lower resting rates predict better outcomes. Whether the heart rate itself is the mechanism or just a marker for a well-tuned cardiovascular system remains an open question in the field.

If you are sitting at 89 BPM, you are burning through your daily allotment of heartbeats about 30% faster than someone cruising at 65. Over decades, that adds up. It is not a reason to panic, but it is another way of seeing why the number deserves attention rather than a shrug.
