What is a normal resting heart rate?
A wearable puts a resting heart rate in front of you every morning. The number is easy to read and easy to over-read, so it helps to know what sits around it.

This is not clinical evidence and not medical advice. It does not replace your care team. Discuss anything here with your clinician before you act on it.
What is a normal resting heart rate?
For most adults it is 60 to 100 beats per minute while you are sitting or lying down, calm and feeling well, according to the American Heart Association. NHLBI gives the same range at rest. MedlinePlus lists 60 to 100 for everyone 10 and older, including seniors. Younger children have different ranges.
Why can fit people have a lower resting heart rate?
A well-conditioned heart doesn't have to work as hard, and the American Heart Association says that is why a lower rate is common for athletes. For well-trained athletes, MedlinePlus lists 40 to 60 beats per minute. The AHA's training page says an athlete or more active person may be as low as 40. If you train and your rate sits below 60, a fair question for your clinician is how it compares with what is usual for you.
What moves your resting heart rate?
Many ordinary things do, which is why a single reading is a snapshot. Strong emotion and pain can push your pulse up, and so can a rise in body temperature. Outside temperature may affect it as well. Standing up may lift it a little, and it should settle again after a few minutes. Exercise raises it too, and after a workout it doesn't drop to resting right away. The American Heart Association says the more often you exercise, the sooner it should return to normal. Caffeine is another. MedlinePlus lists a fast heart rate among the effects of too much caffeine, and says caffeine peaks in your blood within an hour and its effects can last four to six hours. Sleep can pull the other way, since heart rate may be lower while you sleep. A fast pulse may also signal an infection or dehydration.
How is resting heart rate different from heart rate during exercise?
Resting is the rate when you are not exercising. When you do exercise, NHLBI says, your heart beats faster to get more oxygen to your muscles.
When is the best time to check a resting heart rate?
After a quiet stretch, and ideally first thing in the morning. MedlinePlus says you need to have been resting for at least 10 minutes. The American Heart Association suggests the morning after a good night's sleep, before you get out of bed or have your first coffee. A hand count at the wrist works too: beats over 30 seconds, doubled, give beats per minute. If your device reports a resting rate, it can help to find out when it takes that reading, since heart rate may be lower during sleep.
How do wearables estimate heart rate?
With light, and the result is an estimate. A 2020 study by Duke University researchers says wearable heart rate comes from photoplethysmography (PPG), an optical method that measures changes in blood volume under the skin. FDA's general wellness guidance says it may consider non-invasive products, such as those using optical sensing, that "estimate, infer, or output" physiologic parameters to be general wellness products when the outputs are intended solely for wellness uses.
Where can wearable sensors miss?
More often when you are moving than when you are at rest. In one 2020 study, average error during activity was 30% higher than at rest. That study looked at six wearables, and a ring was not among them. Motion can shift a wrist-worn sensor on your skin and show up as missing or false beats. With repeated movement such as walking or jogging, a sensor can lock onto the rhythm of the movement and mistake it for the heartbeat, a pattern the paper describes as signal crossover. The study compared the six devices with a clinical reference patch in 53 people, so it can't say how your own device performs.
Does a rate outside 60 to 100 mean something is wrong?
Not by itself. The American Heart Association says a rate lower than 60 doesn't always signal a medical problem, and that a high rate isn't always a sign of a problem: it could be a sign or symptom of another condition that may be temporary. The same page calls heart rate just one tool for getting a picture of your health. It also says to call 911 if your heart rate is suddenly very high or very low for you, especially with symptoms that may include chest pain, shortness of breath, dizziness, fainting or other signs that something is not right. If your own usual has shifted, a fair question for your clinician is whether the change is worth looking into.
What could you ask about your resting heart rate?
You could ask what range is usual for you. A fair question is how a few mornings of readings compare with a clinic measurement. You could also ask which changes from your usual are worth a call, and which symptoms alongside a change would make a call urgent.
