Your pulse rate is the number of times your arteries expand and contract per minute in response to your heartbeat. For most healthy adults, a normal resting pulse falls between 60 and 100 beats per minute (bpm). Each time your heart squeezes blood into your aorta, the force travels through your arterial walls as a pressure wave you can feel at certain points on your body, like your wrist or neck.
How Pulse Rate Works
Every heartbeat opens and closes a valve at the top of your heart’s main pumping chamber. That opening sends a surge of blood into the aorta, your largest artery, and the pressure ripples outward through smaller arteries all the way to your fingertips. The rhythmic expansion you feel when you press two fingers against your wrist is that pressure wave arriving. One wave equals one heartbeat, so counting those waves over a set time gives you your pulse rate.
Pulse Rate vs. Heart Rate
These two numbers are usually identical, but not always. Your heart rate is how many times your heart squeezes per minute. Your pulse rate is how many of those squeezes produce enough force to create a detectable wave in your arteries. In certain conditions, the heart contracts but doesn’t pump enough blood to register as a pulse. This happens with atrial fibrillation (where the heartbeat is fast and chaotic), heart failure (where the pumping action is too weak), and premature extra heartbeats that fire before the chambers fill with enough blood. In all of these situations, the pulse you count at your wrist can read lower than the actual heart rate.
Normal Ranges by Age
Pulse rate varies significantly with age, especially in children. Here are the typical resting ranges:
- 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 numbers apply when you’re awake and sitting still. Your pulse drops during sleep and rises during physical activity.
Why Endurance Athletes Have Lower Pulses
Highly trained athletes often have resting pulse rates well below 60 bpm. In a study of 465 endurance athletes, 38% had a resting pulse at or below 40 bpm, and a small number dropped as low as 30 bpm. This happens because consistent aerobic training strengthens the heart muscle so it pumps more blood per beat, meaning it doesn’t need to beat as often to circulate the same volume. The nervous system also adapts, increasing the calming signals that naturally slow the heart. Genetics play a role too: both fitness level and inherited traits influence how low an athlete’s resting pulse settles.
What Affects Your Pulse Rate
Your pulse isn’t a fixed number. It shifts throughout the day based on what your body is doing and what’s happening around you.
Exercise is the most obvious driver. The harder you work, the faster your pulse climbs to deliver more oxygen to your muscles. Body temperature matters too: a fever or even a hot day can push your rate up. Emotional states like stress, anxiety, happiness, and sadness all trigger changes, as does pain. Even standing up from a seated position causes a brief, small increase as your circulatory system adjusts to gravity.
Body size plays a role as well. People with obesity tend to have a higher resting pulse than people without. Certain medications deliberately slow the heart, which is why some blood pressure drugs bring your pulse down as part of their intended effect. Caffeine and dehydration can nudge it higher.
How to Check Your Pulse
You can measure your pulse in two easy locations: your wrist and your neck. Before you start, sit quietly for a few minutes so you’re measuring your true resting rate.
At Your Wrist
Turn one hand palm-up. Place the tips of your index and middle fingers on the thumb side of your wrist, in the soft groove between the wrist bone and the tendon. Press lightly until you feel the rhythmic thumping. Count the beats for 60 seconds, or count for 15 seconds and multiply by four.
At Your Neck
Place the tips of your index and middle fingers in the groove alongside your windpipe, just below the jawline. Press gently. Only check one side at a time: pressing both sides simultaneously can make you dizzy or faint. If you’ve been told you have plaque buildup in your neck arteries, skip this location and use your wrist instead.
When Pulse Rate Signals a Problem
Doctors define a resting adult pulse below 60 bpm as bradycardia and above 100 bpm as tachycardia. Neither is automatically dangerous. A fit person with a pulse of 55 is likely healthy, and a pulse of 105 after climbing stairs is completely expected. Context matters.
What does matter is when an unusual pulse rate comes with symptoms. A fluttering, pounding, or racing sensation in your chest, lightheadedness, dizziness, unusual fatigue, and sweating can all signal an arrhythmia, which is an irregular heart rhythm. These episodes might last seconds or persist for hours. Some people describe feeling like their heart “skips” or “flips.”
Chest pain, shortness of breath, and fainting alongside an abnormal pulse are more urgent. These combinations can indicate that the heart isn’t circulating blood effectively and need immediate medical attention. A resting pulse that consistently stays above 120 bpm without an obvious cause like exercise is also worth investigating, since symptoms from irregular rhythms become more likely above that threshold.
Tracking your resting pulse over time gives you a personal baseline. A gradual increase over weeks or months, or sudden jumps that weren’t there before, can be early clues that something has changed, even before other symptoms appear.
