A normal resting pulse for adults falls between 60 and 100 beats per minute (bpm). That range applies when you’re sitting quietly, not right after exercise or a stressful event. Your actual number within that window depends on your fitness level, age, medications, and even the time of day.
Normal Resting Pulse by Age
Adults and older children share the same general range of 60 to 100 bpm, but younger children naturally run much faster. A baby’s heart is smaller and needs to beat more often to move enough blood. Here’s what to expect at different ages while awake:
- Newborn to 3 months: 85 to 205 bpm
- 3 months to 2 years: 100 to 190 bpm
- 2 to 10 years: 60 to 140 bpm
- Over 10 years and adults: 60 to 100 bpm
Children’s heart rates also drop significantly during sleep. A toddler who clocks 160 bpm while crawling around might settle to 75 to 160 bpm while napping, and a school-age child’s sleeping pulse can dip to 60 to 90 bpm. These wide ranges are normal because kids’ heart rates respond dramatically to activity, crying, and fever.
What Happens During Sleep
Your pulse doesn’t stay at its daytime resting rate once you fall asleep. It typically drops 20% to 30% below your waking resting number. So if you normally sit at 70 bpm during the day, you might see readings in the low 50s overnight. This dip happens mostly during deep sleep, when your heart essentially gets a period of rest. During REM sleep (when you dream), your heart rate climbs back up and becomes more variable, sometimes approaching your daytime resting level.
If you wear a fitness tracker, these overnight fluctuations are completely expected. A consistently elevated sleeping heart rate, one that doesn’t show that characteristic dip, can be an early signal of illness, stress, or overtraining.
Why Athletes Have Lower Pulses
Highly trained endurance athletes commonly have resting heart rates between 40 and 60 bpm. Their hearts pump more blood per beat, so fewer beats are needed to circulate the same volume. Some elite cyclists and rowers have been recorded at 30 bpm, and one study of elite athletes documented rates dropping below 30 bpm during nighttime sleep.
A low pulse in a fit person who feels fine is generally a sign of cardiovascular efficiency, not a problem. It becomes a concern when a low rate is paired with dizziness, fainting, unusual fatigue, or shortness of breath, regardless of fitness level.
When a Pulse Is Too Fast or Too Slow
A resting heart rate consistently above 100 bpm is called tachycardia. A rate below 60 bpm is called bradycardia. Neither label automatically means something is wrong. Context matters enormously.
For tachycardia, serious symptoms are uncommon when the rate stays below about 150 bpm in people with otherwise healthy hearts. Above that threshold, or at lower rates in people with existing heart conditions, you may notice chest pain, lightheadedness, or a feeling that your heart is pounding. A resting pulse that regularly sits above 100 bpm without an obvious explanation (like caffeine, anxiety, or dehydration) is worth getting checked.
For bradycardia, athletes aside, a resting rate that frequently dips below 60 bpm deserves attention if it comes with fainting, confusion, chest discomfort, or extreme fatigue. Certain medications are a common cause. Beta blockers and calcium channel blockers, often prescribed for high blood pressure or heart rhythm issues, are well known for slowing the pulse. Some non-heart medications, including certain mood stabilizers and anti-seizure drugs, can do the same.
Factors That Shift Your Pulse
Your resting heart rate isn’t a fixed number. It moves throughout the day in response to what your body is dealing with. Caffeine is one of the most common influences. It blocks a chemical process in your cells in a way that can increase both the force and speed of your heartbeat. Research on energy drinks confirms they raise heart rate depending on the caffeine dose, and one trial found that coffee drinkers had a 54% increase in premature heartbeats compared to those who avoided caffeine.
Beyond caffeine, several other factors reliably bump your pulse up or bring it down:
- Stress and anxiety: Activate your fight-or-flight response, pushing your rate well above your true resting baseline.
- Dehydration: Less fluid in your bloodstream means your heart compensates by beating faster.
- Fever and illness: Your heart rate increases roughly 10 bpm for every degree (Fahrenheit) of fever.
- Heat and humidity: Your heart works harder to cool your body, raising your rate even at rest.
- Body position: Standing tends to produce a slightly higher reading than sitting or lying down.
This is why the conditions under which you check your pulse matter just as much as the number you get.
How to Measure Your Pulse Accurately
For the most reliable reading, sit down and rest quietly for a few minutes before you start. You can check your pulse at two easy-to-find spots.
At Your Wrist (Radial Artery)
Turn one hand palm-up. Place the tips of your index and middle fingers from the other hand on the thumb side of your wrist, in the groove between the wrist bone and the tendon. Press lightly until you feel a steady beat. Pressing too hard can actually block blood flow and make the pulse harder to detect.
At Your Neck (Carotid Artery)
Place the tips of your index and middle fingers in the groove beside your windpipe, on one side of your neck. Never press on both sides at once, as this can make you dizzy or faint. Again, use gentle pressure.
Count the beats for a full 60 seconds for the most accurate result. A common shortcut is to count for 15 seconds and multiply by four, but this amplifies any counting errors. If your rhythm feels irregular, with skipped beats or an uneven pattern, the full 60-second count is especially important.
Target Heart Rate During Exercise
Your maximum heart rate is roughly 220 minus your age. During moderate exercise (brisk walking, easy cycling), you want to hit about 50% to 70% of that maximum. During vigorous exercise, aim for 70% to 85%. Here’s what that looks like in practice:
- Age 20: 100 to 170 bpm
- Age 30: 95 to 162 bpm
- Age 40: 90 to 153 bpm
- Age 50: 85 to 145 bpm
- Age 60: 80 to 136 bpm
- Age 70: 75 to 128 bpm
These are guidelines, not hard limits. If you’re just starting to exercise, staying in the lower half of your target zone and building up gradually is a practical approach. The numbers also assume you’re not on medications that cap your heart rate. Beta blockers, for instance, can make it physically impossible to reach these targets, which doesn’t mean you’re not getting a good workout.
