Most of us hardly ever think about our heart until we’ve sprinted for a bus or had a stressful day.
However, the number of times your heart beats per minute when you’re sitting quietly, known as your resting heart rate, can tell you a surprising amount about your overall health. Knowing what’s normal for your age is one of the simplest health checks you can do at home. And while it doesn’t paint a complete picture of what’s going on inside of you, it’s a vital jumping off point. Here’s exactly what your resting heart rate should look like, and what the numbers actually mean.
What your resting heart rate actually is
Your resting heart rate, sometimes shortened to RHR, is how many times your heart beats per minute when you’re sitting still and relaxed. It’s one of the easiest health markers to measure, and one of the most useful. A healthy resting heart rate gives doctors a quick window into how well your heart is doing its job, how fit you are, and whether anything might be going on behind the scenes.
For most healthy adults, a resting heart rate of between 60 and 100 beats per minute is considered normal. Where you sit within that range depends on your age, fitness, stress levels, medications, and even the time of day you check it. Generally speaking, lower numbers within the healthy range are better, since they tend to point to a stronger, more efficient heart.
The normal resting heart rate from birth to teen years
Resting heart rates vary a lot across different ages, particularly in childhood, when little hearts naturally beat much faster than adult ones. Newborns up to one month old typically have a resting heart rate of 70 to 190 beats per minute. Infants between one and eleven months old usually sit around 80 to 160. Toddlers aged one to two tend to fall between 80 and 130.
For children aged three to four, the average drops to 80 to 120. Five and six-year-olds sit around 75 to 115. Children aged seven to nine typically fall between 70 and 110. From the age of ten upwards, the range settles into the standard adult range of 60 to 100, where it stays for the rest of your life.
What your resting heart rate should look like as an adult
Once you’re an adult, the healthy range stays the same across every decade of your life, sitting between 60 and 100 beats per minute. Most healthy adults in their 20s, 30s, and 40s average somewhere between 60 and 80, with active people closer to 60 to 70 and more sedentary people nearer 75 to 85. Women tend to have a slightly higher resting heart rate than men by a few beats per minute, which is completely normal.
In your 50s, 60s, and 70s, most healthy adults still average somewhere between 65 and 85, with the range itself unchanged. What tends to change with age isn’t the healthy range but the lifestyle factors that affect it, including weight, exercise levels, stress, and medications. Older adults on certain heart medications like beta blockers may have a noticeably lower resting heart rate, which is usually a sign the medication is doing its job well.
Why athletes have a much lower resting heart rate
If you’ve ever wondered why marathon runners and serious cyclists often have a resting heart rate in the 40s or low 50s, it comes down to how strong their heart muscle has become. Regular cardiovascular training makes the heart bigger and more powerful, so it can pump more blood with each beat. That means it doesn’t need to beat as often to get the job done.
For most non-athletes, a resting heart rate that gradually drops over months of regular exercise is a brilliant sign your fitness is improving. Even modest changes, like dropping from 80 to 70 beats per minute, can reflect a meaningful boost in heart health. The number on the screen of your fitness tracker isn’t just a stat, it’s a little progress report.
How the active exercise zone is different
It’s worth being clear that resting heart rate is completely different from the heart rate you hit when you’re actively working out. When you exercise, your heart rate naturally climbs into what’s known as your target heart rate zone. Your maximum possible heart rate is roughly 220 minus your age, so at 30 you’d hit a max of around 190 beats per minute, at 50 around 170, and at 70 around 150.
For moderate exercise like a brisk walk or easy swim, aim for around 50 to 70% of that maximum. For more intense activity like running or hill climbs, the target is 70 to 85%. None of these numbers should be confused with your resting heart rate, which is purely what your heart does while you’re at rest.
What causes a higher than normal resting heart rate
If your resting heart rate is regularly higher than expected for your age, there are loads of possible reasons. Stress, anxiety, caffeine, nicotine, alcohol and certain medications can all push the number up. Being dehydrated, running a fever, or fighting off a virus will do the same. Even a poor night’s sleep can leave your resting heart rate a few beats higher the next day.
More serious causes can include thyroid problems, particularly an overactive thyroid, which often comes with weight loss, sweating and feeling jittery. Heart conditions and lung problems can also raise your resting heart rate. If yours has crept up over time, and you can’t pin it on lifestyle factors, it’s worth flagging to your GP.
How to measure your resting heart rate at home
You don’t need fancy kit to check your resting heart rate. Find your pulse either on the inside of your wrist below the thumb, or on the side of your neck just below the jawline. Press gently with two fingers, not your thumb, and count the beats for 30 seconds. Then double the number to get beats per minute.
For the most accurate reading, check your resting heart rate first thing in the morning before you get out of bed, when you’ve been still and relaxed for hours. Take it across several days and average the numbers to get a reliable picture. Most fitness watches, smartwatches, and rings will do all of this for you automatically, often producing very accurate readings over time.
How to gently lower your resting heart rate
A slightly elevated resting heart rate is almost always something you can nudge in the right direction with simple lifestyle changes. Regular exercise is the single most powerful tool, since it strengthens the heart muscle and makes it more efficient over time. Even a couple of brisk 30-minute walks a week can start to make a difference within a few months.
Cutting back on caffeine, sorting out your sleep, managing stress with deep breathing or yoga, drinking more water and eating a balanced diet all help too. Stopping smoking is one of the biggest wins of all, since smokers consistently have higher resting heart rates than non-smokers. Stacked together, these small changes can change your resting heart rate in a healthier direction within a season.
When to see a GP
Most healthy adults don’t need to think about their resting heart rate beyond knowing roughly where they sit. A consistently high resting heart rate of over 100 beats per minute is worth flagging, particularly if you’ve noticed it across multiple readings on different days. A very low resting heart rate paired with symptoms like dizziness, fainting, or breathlessness is also worth getting checked.
The same goes if your heartbeat feels weirdly irregular or fluttery, or if you experience chest pain, unusual tiredness or shortness of breath alongside any changes. Your resting heart rate is just one piece of the wider health picture, and a quick check-up can usually rule out anything serious or catch a small issue before it becomes a bigger one.
