A resting heart rate of 87 beats per minute falls within the traditional “normal” range of 60 to 100 BPM that most doctors reference, but it sits in a zone where cardiovascular risk begins to rise compared to lower rates. The clinical cutoff of 100 BPM was never meant to be a clean dividing line between healthy and unhealthy. Large studies tracking hundreds of thousands of people now show that risk increases gradually, and 87 BPM lands closer to the concerning end of the spectrum than the comfortable middle.
Where 87 BPM Sits on the Risk Spectrum
The most informative way to think about resting heart rate isn’t as a pass/fail number but as a sliding scale. A meta-analysis pooling data from multiple large studies found that people with a resting heart rate between 60 and 80 BPM had roughly a 12% higher risk of dying from any cause compared to those in the lowest heart rate category, while people above 80 BPM had about a 45% higher risk of dying from any cause and a 33% higher risk of cardiovascular death specifically.1PubMed Central. Resting heart rate and all-cause and cardiovascular mortality in the general population: a meta-analysis Those elevated risks held even after the researchers accounted for other well-known risk factors like blood pressure, cholesterol, and smoking.
A 2025 study comparing data from nearly 700,000 adults in Asia and Europe reinforced the pattern, finding that people with a resting heart rate between 80 and 99 BPM had a notably elevated risk of death from all causes.2Progress in Cardiovascular Diseases. Resting heart rate – The forgotten risk factor? Comparison of resting heart rate and hypertension as predictors of all-cause mortality in 692,217 adults in Asia and Europe At 87 BPM, you’re inside that window. That doesn’t mean you should panic, but it does mean a resting rate in the upper 80s is worth paying attention to rather than dismissing simply because it falls below 100.
Research on younger adults tells a similar story. A cohort study following people from their late teens into middle age found that each 10-BPM increase in resting heart rate was linked to roughly a 17 to 26% higher risk of dying over long-term follow-up, and this association applied to both cardiovascular and non-cardiovascular causes of death.3PubMed Central. Resting heart rate and long-term mortality in young adults: a population-based cohort study So the idea that heart rate only matters for older people doesn’t hold up.
Why the “Normal” Range Is So Wide
The 60-to-100 range exists because hearts vary enormously based on fitness, genetics, body size, and autonomic nervous system tone. Your heart’s natural pacemaker, the sinoatrial node, would actually fire at about 100 beats per minute if it were left entirely to its own devices. In a living person, the vagus nerve applies a constant brake on that rate, slowing it down. People with strong vagal tone tend to have lower resting rates, sometimes in the 50s or even 40s, while people with weaker vagal influence or higher sympathetic nervous system activity run faster.4PubMed Central. Autonomic and endocrine control of cardiovascular function
This is why the clinical range is really a statistical description of what doctors encounter in healthy people, not a statement that every number inside it carries equal health implications. A fit distance runner at 48 BPM and a sedentary person at 95 BPM are both “normal” by the textbook, but their cardiovascular fitness levels and long-term risk profiles look nothing alike.
Age and Sex Differences
Resting heart rate tends to drift downward as you get older. A study examining heart rate across age groups found a statistically significant decline from the youngest bracket (average around 77 BPM) to older groups (averaging closer to 73 BPM), and women consistently had slightly higher resting rates than men across every age group.5PubMed Central. Does the Aging Process Significantly Modify the Mean Heart Rate? The differences were real but modest, amounting to a few beats per minute in either direction.
What this means for interpreting 87 BPM depends partly on who you are. If you’re a 25-year-old woman, 87 is higher than average for your age group but not dramatically so. If you’re a 60-year-old man who exercises regularly, 87 is further from the expected average and worth looking into. Context matters, and a single number taken in isolation doesn’t tell the full story.
Fitness Is the Biggest Modifiable Factor
Of all the things that influence resting heart rate, cardiovascular fitness has the most dramatic effect. People who exercise regularly develop a more efficient heart that pumps more blood per beat, meaning it doesn’t need to beat as frequently at rest. Research comparing people who maintained a regular exercise routine with sedentary controls found significant differences in resting heart rate and maximal oxygen uptake between the groups.6PubMed Central. The effects of strenuous exercises on resting heart rate, blood pressure, and maximal oxygen uptake
If your resting heart rate is 87 and you’re relatively inactive, that number is probably more a reflection of deconditioning than disease. Consistent aerobic exercise over a period of weeks to months can bring resting heart rate down substantially, often by 10 to 20 BPM in previously sedentary people. This is one of the most reliable and well-documented effects of regular cardio, and it’s one reason researchers think lower resting rates correlate with better longevity outcomes: the rate itself is partly a marker for overall fitness.
Everyday Things That Temporarily Push Your Rate Up
Before deciding 87 is “your” number, consider what was happening when you checked. Resting heart rate is surprisingly sensitive to short-term influences, and a reading taken under imperfect conditions may overestimate your true baseline by 5 to 15 BPM.
Alcohol is one of the most potent acute influences. A large real-world study using wearable data found that drinking just one drink more than a person’s usual amount was associated with a resting heart rate increase of about 2.4 to 2.8 BPM that night, with the effect more pronounced in women than men.7PubMed Central. Real-world effects of alcohol on heart rate, sleep, and physical activity by age and sex Heavier drinking produces proportionally larger spikes. A separate study confirmed that alcohol significantly raised nocturnal heart rate compared to a placebo.8PubMed Central. Effects of alcohol on sleep and nocturnal heart rate: Relationships to intoxication and morning‐after effects If you check your heart rate the morning after a few drinks, you may be seeing a temporarily inflated number.
Caffeine’s effect is more complicated than most people assume. A sleep-deprivation study that tested caffeine at two different doses found that a moderate dose (200 mg, roughly the caffeine in a large coffee) actually lowered heart rate compared to placebo, likely by boosting vagal tone.9PubMed Central. Cardiac autonomic activity during sleep deprivation with and without caffeine administration A higher dose (300 mg) did not produce a significant heart rate change compared to placebo. So the popular belief that coffee automatically speeds up your heart is an oversimplification. For most people, moderate caffeine intake has a minimal effect on resting rate.
Psychological stress is another common culprit. Acute stress activates the sympathetic nervous system and reliably increases heart rate, though interestingly, the size of the actual heart rate change during a stressful moment doesn’t correlate well with how anxious a person feels. Instead, what people perceive their heart rate is doing matters more for their subjective anxiety.10PubMed. Associations between heart rate, perceived heart rate, and anxiety during acute psychological stress If you’re feeling anxious when you check your pulse, the number may be 10 or more BPM above your true resting baseline.
Eating a meal also has a measurable effect. The body diverts blood to the digestive system after eating, and to compensate, heart rate increases by an average of about 8 BPM. This postprandial bump can take up to four hours to fully return to baseline.11PubMed Central. The Cardiovascular Effects of a Meal: J‐T peak and T peak ‐T end Assessment and Further Insights Into the Physiological Effects A reading taken shortly after lunch could easily push you from 79 to 87.
How to Get an Accurate Reading
Given all of these transient influences, the best way to know your true resting heart rate is to measure it first thing in the morning, before getting out of bed, after a night of normal sleep without alcohol. Sit upright for a minute or two if you prefer not to measure while lying down, then check. Do this on several consecutive mornings and average the results. A single reading on a single day is essentially a snapshot that could be skewed by any of the factors above.
If you use a wrist-based wearable like a smartwatch, the optical sensor technology (photoplethysmography) is reasonably accurate at rest. A study in cardiac patients found that optical pulse readings correlated very highly with electrocardiogram readings, with the heart rate measurement typically falling within about 4 BPM of the gold standard.12Journal of Electrocardiology. The accuracy of heartbeat detection using photoplethysmography technology in cardiac patients That’s good enough for tracking trends and identifying whether you’re at 70 versus 87.
One caveat: accuracy can vary with skin tone, especially during movement. Some smartwatch brands have been found to underestimate heart rate by 10 to 15 BPM in darker-skinned users during exercise, though the error was much smaller during rest and varied by device. Apple Watch devices showed less than 5 BPM variation across skin tones in comparative testing.13PubMed Central. Photoplethysmography in Diverse Skin Tones: Evaluating Bias in Smartwatch Health Monitoring If you have darker skin and rely on a wearable for heart rate data, it’s worth spot-checking against a manual pulse count, especially if you’re making health decisions based on the numbers.
What Your Heart Rate Does at Night
Most people’s heart rate drops significantly during sleep, typically falling 10 to 20% below their waking resting rate. This nocturnal dip is a sign that the parasympathetic nervous system is doing its job, and it turns out to be independently important for health. People whose heart rate fails to drop adequately at night, sometimes called “non-dippers,” face substantially elevated cardiovascular risk. One study of hypertensive patients found that those whose heart rate didn’t exhibit the normal nighttime decline had about 2.4 times the risk of future cardiovascular disease compared to those who dipped normally.14PubMed Central. Nocturnal Non-dipping Of Heart Rate Predicts Cardiovascular Events In Hypertensive Patients Another study found that people in the lowest decile for heart rate dipping had roughly 2.7 times the mortality risk of those in the highest decile.15Archives of Internal Medicine. Blunted Heart Rate Dip During Sleep and All-Cause Mortality
Poor sleep quality itself may be part of the problem. In young, otherwise healthy adults, those with lower sleep efficiency showed a blunted nighttime dip in heart rate (about 12% versus 21% in good sleepers) and had higher average nocturnal rates, around 63 BPM compared to 55 BPM in people who slept more soundly.16PubMed. Sleep efficiency and nocturnal hemodynamic dipping in young, normotensive adults If your wearable shows that your sleeping heart rate stays elevated, improving sleep hygiene may be a more immediate lever than exercise for bringing it down.
For someone whose daytime resting rate is 87, the nighttime numbers offer additional context. If your sleeping heart rate drops into the mid-60s, your autonomic nervous system is behaving normally and the daytime 87 may partly reflect measurement timing or mild deconditioning. If it stays in the 80s even during deep sleep, that’s a different picture and worth discussing with a doctor.
When to Think Beyond Lifestyle
A persistently elevated resting heart rate that doesn’t respond to improved fitness, better sleep, and reduced alcohol intake can sometimes signal an underlying medical issue. The most common culprits are thyroid disorders (hyperthyroidism speeds up nearly every metabolic process, including heart rate), anemia (the heart compensates for reduced oxygen-carrying capacity by beating faster), and dehydration or chronic low blood volume.
Two lesser-known conditions are worth mentioning. Inappropriate sinus tachycardia (IST) is a condition where the heart’s natural pacemaker fires faster than expected for no identifiable reason, leading to a resting rate that often sits above 90 BPM without an obvious trigger. Postural tachycardia syndrome (POTS) involves an excessive heart rate increase when standing up, though resting rates can also be elevated. The two conditions can look similar, and autonomic testing is used to tell them apart.17Autonomic Testing. Case 27: Inappropriate Sinus Tachycardia Versus Postural Tachycardia Syndrome If you consistently notice your heart racing at rest and you don’t have an obvious explanation like caffeine or stress, these are conditions your doctor can evaluate.
Certain medications also raise resting heart rate as a side effect. Decongestants, some asthma inhalers, stimulant medications for ADHD, and some antidepressants can all push the baseline up by 5 to 15 BPM. If you started a new medication around the time you noticed a higher rate, that’s worth flagging to your prescriber.
Altitude and Heat
If you’ve recently traveled to a high-altitude location, a temporarily elevated heart rate is expected. The lower oxygen levels at altitude trigger the sympathetic nervous system, initially pushing heart rate up to compensate for reduced oxygen delivery to tissues.18PubMed. Cardiovascular adaptation to exercise at high altitude Over time, the body acclimatizes: a study tracking low-altitude migrants living at about 5,400 meters found that heart rate spiked in the first few days and then gradually returned to baseline values by around six months.19PubMed. Changes in blood pressure, oxygen saturation, hemoglobin concentration, and heart rate among low-altitude migrants living at high altitude (5380 m) for 360 days If you live at moderate altitude (say, Denver or Mexico City), the effect is much smaller but may still add a few BPM to your baseline compared to someone at sea level.
Heat works through a similar mechanism. When your body needs to dissipate heat, blood vessels near the skin dilate, blood pressure drops slightly, and the heart speeds up to maintain circulation. A hot bath, a warm room, or a summer day can all bump your resting rate up temporarily. If you’re checking your heart rate in a stuffy room after walking in from the sun, give yourself 15 to 20 minutes in a cool environment before taking the measurement seriously.
The Heartbeat-Lifespan Connection Across Species
There’s an old observation in comparative physiology that smaller mammals with faster heart rates tend to live shorter lives. Across mammalian species, there’s an inverse relationship between resting heart rate and lifespan.20PubMed. Rest heart rate and life expectancy A mouse’s heart beats about 600 times per minute and it lives two to three years; an elephant’s heart beats around 30 times per minute and it can live 60 or more years. In rough terms, most mammals seem to get a similar total number of heartbeats in a lifetime, somewhere around a billion, regardless of size.
It’s tempting to apply this directly to humans and conclude that a faster heart rate literally “uses up” your heartbeats sooner, but the relationship doesn’t work so cleanly within a single species. Humans already live far longer than the cross-species trend would predict for our body size and heart rate. Still, the epidemiological data showing that lower resting rates correlate with longer life in humans does echo the broader mammalian pattern in an interesting way. The connection is probably less about a fixed heartbeat budget and more about what a lower heart rate signals: better cardiovascular fitness, stronger parasympathetic tone, and lower levels of chronic physiological stress.
Practical Steps If Your Rate Feels Too High
If you’ve confirmed that your true resting heart rate is consistently around 87 BPM after measuring properly on multiple mornings, a few concrete strategies are most likely to move the needle. Regular aerobic exercise is the single most effective intervention. Even moderate-intensity activity like brisk walking or cycling for 30 minutes most days of the week can produce measurable reductions in resting heart rate within a few weeks, with larger improvements over months. You don’t need to train for a marathon; consistency matters more than intensity for this particular outcome.
Reducing alcohol intake is another straightforward lever, especially if you drink most evenings. As the wearable data study showed, the heart rate effect of alcohol is dose-dependent, meaning every drink adds to the bump.7PubMed Central. Real-world effects of alcohol on heart rate, sleep, and physical activity by age and sex Cutting back from three drinks to one on a given evening could lower your overnight and next-morning resting rate by several BPM.
Improving sleep quality also has downstream effects on heart rate. As noted earlier, poor sleep efficiency blunts the normal nighttime heart rate dip and raises the overall nocturnal average.16PubMed. Sleep efficiency and nocturnal hemodynamic dipping in young, normotensive adults Addressing obvious sleep disruptors like late-night screen use, inconsistent bedtimes, and bedroom temperature can help restore a healthier nighttime pattern, and this tends to pull daytime rates down as well.
Finally, if you’re doing all of these things and your resting rate remains stubbornly elevated, a check-in with your doctor to screen for thyroid dysfunction, anemia, or autonomic conditions is reasonable. A resting rate of 87 doesn’t demand urgent intervention on its own, but treating it as a signal to improve your cardiovascular fitness and daily habits is well-supported by the evidence.
