A good resting heart rate for adults falls between 60 and 100 beats per minute (bpm). Within that range, lower is generally better. A resting heart rate in the 60s or 70s suggests your heart is pumping efficiently without overworking, while rates consistently near the top of the range may signal that your cardiovascular system is under more strain.
Normal Resting Heart Rate by Age
Your resting heart rate is the number of times your heart beats each minute while you’re awake, calm, and sitting still. For adults and teenagers, the healthy window is 60 to 100 bpm. But younger children have naturally faster hearts because their bodies are smaller and their hearts need to beat more frequently to circulate blood.
- Newborns (birth to 4 weeks): 100 to 205 bpm
- Infants (4 weeks to 1 year): 100 to 180 bpm
- Toddlers (1 to 3 years): 98 to 140 bpm
- Preschool age (3 to 5 years): 80 to 120 bpm
- School age (5 to 12 years): 75 to 118 bpm
- Adolescents (13 to 17 years): 60 to 100 bpm
- Adults (18 and older): 60 to 100 bpm
These ranges apply when you’re awake and not exercising. Heart rate drops during sleep and rises during physical activity, both of which are completely normal.
Why Lower Is Usually Better
A lower resting heart rate typically means your heart muscle is strong enough to push out more blood with each beat, so it doesn’t need to beat as often. This is why cardiovascular fitness and resting heart rate are closely linked. As you get more aerobically fit, your heart becomes a more efficient pump, and your resting rate tends to drift downward over time.
Highly trained endurance athletes take this to an extreme. Up to 80% of endurance athletes develop resting heart rates below 60 bpm, and about 38% recorded minimum rates at or below 40 bpm in one study of 465 athletes published in Circulation. A small number (around 2%) even dropped to 30 bpm or below. For these individuals, a heart rate that would be concerning in a sedentary person is a sign of a well-adapted cardiovascular system. Both fitness level and genetics play a role in how low an athlete’s heart rate goes.
When Your Heart Rate Is Too High or Too Low
A resting heart rate consistently above 100 bpm is called tachycardia. It can be caused by stress, dehydration, fever, anemia, thyroid problems, or heart conditions. A rate below 60 bpm is called bradycardia. In someone who isn’t physically active or athletic, bradycardia can sometimes indicate a problem with the heart’s electrical system.
Neither number is automatically dangerous on its own. Context matters. A resting rate of 105 after three cups of coffee and a stressful morning is different from a resting rate of 105 every time you check it over several weeks. Similarly, a fit person who regularly exercises and sits at 55 bpm is in a very different situation than someone with dizziness and fatigue at the same rate.
What Affects Your Heart Rate Day to Day
Your resting heart rate isn’t a fixed number. It fluctuates based on what’s happening in your body and environment. Caffeine is one of the most common influences. Consuming more than 400 mg daily (roughly four cups of coffee) significantly raises heart rate by stimulating the autonomic nervous system, the part of your nervous system that controls involuntary functions. People who regularly exceeded 600 mg daily showed elevated heart rates that persisted even after resting, according to data presented through the American College of Cardiology.
Stress and anxiety activate your fight-or-flight response, which directly speeds up your heart. Dehydration forces your heart to beat faster because there’s less blood volume to circulate. Nicotine, poor sleep, illness, and certain medications can all push your rate higher. Even body position matters: your heart rate is slightly higher when standing than when sitting or lying down.
Your Heart Rate During Sleep
Your sleeping heart rate typically runs 20% to 30% lower than your daytime resting rate. For a healthy adult with a waking resting rate of 60 to 100 bpm, that translates to roughly 50 to 75 bpm during sleep. The lowest point usually occurs during deep sleep (non-REM stages), when your heart rate and blood pressure both cycle down as your body focuses on repair and recovery. Your rate climbs slightly during REM sleep, when your brain is more active and dreaming.
If you wear a fitness tracker overnight, don’t be alarmed by seeing numbers in the 40s or 50s. That dip is your heart shifting into a lower gear, and it’s a normal part of healthy sleep physiology.
Heart Rate During Exercise
During exercise, a “good” heart rate depends on your age and fitness goals. Your estimated maximum heart rate is roughly 220 minus your age. For moderate-intensity exercise like brisk walking, you want to stay at about 50% to 70% of that maximum. For vigorous activity like running, aim for 70% to 85%.
For a 40-year-old, that means a maximum of about 180 bpm, a moderate zone of 90 to 126 bpm, and a vigorous zone of 126 to 153 bpm. For a 60-year-old, the target range for moderate to vigorous exercise falls between about 80 and 136 bpm. These are estimates, not hard rules. Some people naturally run higher or lower based on fitness level, medications, and individual variation.
Heart Rate Recovery After Exercise
How quickly your heart rate drops after you stop exercising is one of the best indicators of cardiovascular fitness. A good benchmark is a drop of 18 beats or more within the first minute of rest. If your heart rate stays elevated and barely budges after stopping, that may indicate your cardiovascular system is working harder than it should to recover. As you get fitter, your recovery time tends to improve noticeably.
How to Measure Your Heart Rate Accurately
The simplest method is a manual pulse check. Sit quietly for a few minutes, then turn one hand palm-up. Place the index and middle fingers of your other hand on the inside of your wrist, between the bone and the tendon on the thumb side. Press lightly until you feel each beat. Count the beats for 60 seconds using a clock or timer. Some people count for 15 seconds and multiply by four, though a full 60-second count is more accurate.
You can also check your pulse at your neck. Find the groove alongside your windpipe and press gently with two fingers. Don’t push too hard at either location, as too much pressure can actually block blood flow and give you an inaccurate reading.
Smartwatches and fitness trackers offer continuous monitoring, which is convenient for spotting trends over days and weeks. However, wrist-based optical sensors aren’t always precise, particularly during movement or for people with certain heart conditions. They’re useful for general patterns but shouldn’t replace a manual check or a medical reading if something feels off. For the most reliable resting measurement, check your pulse first thing in the morning before getting out of bed, when your body is closest to a true baseline.
