Resting heart rate by age, and what the numbers mean
For most adults, including older adults, a normal resting heart rate is 60 to 100 beats per minute. Children's ranges are higher and well-trained athletes can be lower. A single reading means little; a pulse that stays too fast or too slow, or feels irregular, is worth a doctor's visit.
The short version for adults
Cleveland Clinic says a normal resting heart rate for most adults is 60 to 100 beats per minute. MedlinePlus gives the same range for everyone aged 10 and over, adults and seniors included. So there is no separate, lower "normal" range once you pass 60: the range stays 60 to 100.
Your resting heart rate is your pulse when you are calm and still, not just after climbing stairs or arguing with someone. The best time to catch it is sitting quietly, or from a wearable that measures during rest and sleep.
Normal resting heart rate by age
These are Cleveland Clinic's ranges. MedlinePlus splits the childhood years a little differently, so treat the edges as approximate.
- Newborn (birth to 4 weeks): 100 to 205 beats per minute
- Infant (4 weeks to 1 year): 100 to 180
- Toddler (1 to 3 years): 98 to 140
- Preschool (3 to 5 years): 80 to 120
- School age (5 to 12 years): 75 to 118
- Teenagers (13 to 17 years): 60 to 100
- Adults (18 and over): 60 to 100
MedlinePlus adds that well-trained athletes can have a resting rate of 40 to 60 beats per minute. A low number is not a problem on its own if you are very fit and feel well.
What moves your resting heart rate
Cleveland Clinic lists several things that raise or lower your pulse. Many of them change from day to day, which is why one reading is not the whole story:
- stress, anxiety and other emotions
- your fitness level, since athletes usually run lower
- medicines that speed up or slow down the heart
- pregnancy, which raises resting heart rate
- poor sleep, which can push it up
- alcohol, caffeine and smoking
- your weight and long-term health conditions
MedlinePlus also notes that a fast pulse may signal an infection or dehydration. If your resting rate jumps for several days with no clear reason, mention it to a doctor.
When to see a doctor
Cleveland Clinic advises seeking immediate medical attention if your heart rate is below 35 to 40 or above 100 beats per minute and you also have palpitations, shortness of breath, chest pain or dizziness. If you have those symptoms, do not wait. Call your local emergency number.
Without symptoms, both sources still say to contact a provider if your resting heart rate is consistently too fast or too slow, or if your pulse feels irregular. MedlinePlus also lists a very firm, bounding pulse that lasts more than a few minutes.
Using a ring to watch your trend
A one-off finger check tells you little. What helps is your own baseline: your usual resting rate over weeks. The Zenlyf Ring is asked by the Zenlyf app for a reading about every 5 minutes, and the readings appear in the app, so you can see how your own resting rate moves over time. A change from your usual is a prompt to look into it, not a diagnosis.

Common questions
Not by itself. MedlinePlus says well-trained athletes can sit at 40 to 60. If you are not especially fit and also feel dizzy, faint or short of breath, see a doctor.
According to MedlinePlus and Cleveland Clinic, the normal resting range stays at 60 to 100 for adults and seniors alike.
Cleveland Clinic lists poor sleep as one of the things that can raise heart rate. If it stays high for days, mention it to a doctor.
