Your pulse rate is the number of times your arteries expand and contract per minute in response to your heart pumping blood. For most adults, a normal resting pulse falls between 60 and 100 beats per minute (bpm). It’s one of the simplest vital signs to check on your own, and it can tell you a surprising amount about your fitness, stress levels, and overall heart health.
How Your Pulse Works
Every time your heart contracts, it ejects blood into the aorta, your body’s largest artery. That sudden surge of blood creates a pressure wave that travels through the entire arterial system, moving roughly 20 times faster than the blood itself. When you press your fingers against an artery close to the skin’s surface, you feel that wave as a rhythmic throb. Each throb represents one heartbeat.
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 expand an artery you can feel. Sometimes the heart contracts but doesn’t pump with enough force to generate a detectable pulse. When your pulse reads lower than your actual heart rate, the gap is called a pulse deficit.
A pulse deficit can show up in people with atrial fibrillation (where heartbeats are fast and chaotic), heart failure (where the pumping action is too weak), or premature ventricular contractions (extra heartbeats that fire before the heart chambers fill with enough blood). For most healthy people checking their pulse at home, the two numbers will match.
Normal Resting Ranges by Age
Pulse rate varies dramatically across the lifespan. Smaller hearts beat faster to circulate the same volume of blood, which is why a newborn’s resting pulse can be triple an adult’s.
- Newborns (0 to 1 month): 100 to 160 bpm
- Infants (1 to 12 months): 80 to 140 bpm
- Toddlers (1 to 3 years): 80 to 130 bpm
- Preschoolers (3 to 5 years): 80 to 110 bpm
- School-age children (6 to 12 years): 70 to 100 bpm
- Adolescents and adults: 60 to 100 bpm
Well-trained athletes often have resting rates in the 40s or 50s. Their hearts pump more blood per beat, so fewer beats are needed to meet the body’s demands. A resting pulse below 60 bpm in a fit person is normal and not a cause for concern on its own.
What Affects Your Pulse Rate
Your resting pulse isn’t a fixed number. It shifts throughout the day and responds to dozens of influences. Some are obvious, like exercise pushing your rate up, and some are less intuitive.
Age and sex. Pulse rate generally trends downward from infancy to adulthood. The balance between the “speed up” and “slow down” branches of the nervous system differs between males and females, creating small gender-based differences in pulse variability. These differences narrow after about age 50.
Body temperature and illness. Infection and inflammation raise your resting pulse. A fever can push your rate up by roughly 10 bpm for every degree Fahrenheit above normal, because your heart works harder to support the immune response.
Caffeine, alcohol, and smoking. Caffeine is a stimulant that temporarily raises pulse rate. Alcohol activates the body’s “fight or flight” nervous system while suppressing the calming branch, which can bump your rate up, especially after several drinks. Heavy cigarette smoking has a measurable negative effect on the nervous system’s ability to regulate heart rhythm.
Stress and emotions. Anxiety, chronic stress, and depression all influence pulse variability. Your heart rate tends to be higher during periods of mental strain because stress hormones keep the body in a mildly activated state. Even your breathing pattern matters: your pulse naturally speeds up slightly as you inhale and slows as you exhale.
Time of day. Your pulse follows your circadian rhythm. It typically runs lower at night while you sleep and rises during the day as activity and alertness increase.
How to Check Your Pulse
You need nothing more than two fingers and a clock. Sit down and rest quietly for a few minutes before you start, since even walking across the room will nudge your rate up.
At the wrist (radial pulse). Turn one hand palm-up. Place the tips of your index and middle fingers on the inner wrist, just below the base of your thumb, in the soft groove between the wrist bone and the tendon. Press lightly until you feel a steady beat.
At the neck (carotid pulse). Place the tips of your index and middle fingers in the groove beside your windpipe on one side of your neck. Press gently. Never press both sides at the same time, as this can make you dizzy or faint. If you’ve been told you have plaque buildup in your neck arteries, skip this method.
Count the beats for a full 60 seconds for the most accurate reading. A quicker method is counting for 15 seconds and multiplying by four, though this can magnify any counting errors.
Pulse Rate During Exercise
Your pulse is the most practical way to gauge how hard your heart is working during a workout. The standard formula for estimating your maximum heart rate is 220 minus your age. A 40-year-old, for example, would have an estimated max of 180 bpm.
Moderate-intensity exercise, like brisk walking or an easy bike ride, typically keeps your pulse between about 55% and 69% of that maximum. For the 40-year-old, that’s roughly 99 to 124 bpm. Vigorous activity pushes you higher. Staying within these ranges helps you exercise effectively without overloading your cardiovascular system, and tracking your pulse over weeks or months is one of the simplest ways to watch your fitness improve. As your heart gets stronger, the same workout will produce a lower pulse.
When a High or Low Pulse Is Concerning
A resting pulse consistently above 100 bpm is considered tachycardia. A resting pulse below 60 bpm is the traditional threshold for bradycardia, though many cardiologists consider rates above 50 bpm normal in otherwise healthy adults. Population studies frequently use 50 bpm as the more clinically meaningful cutoff.
A single high reading after coffee or a stressful phone call doesn’t mean much. What matters more is a pattern: a resting pulse that stays elevated over days or weeks, or one that drops unusually low alongside symptoms like fatigue or lightheadedness.
Certain symptoms alongside an abnormal pulse warrant urgent attention. Chest pain or discomfort, fainting, severe shortness of breath, or severe dizziness combined with a racing or irregular heartbeat are signs that the heart’s electrical system or pumping ability may be compromised. These combinations call for emergency evaluation, not a wait-and-see approach.
Tracking Your Pulse Over Time
A single pulse reading is a snapshot. The real value comes from tracking your resting rate over weeks and months, ideally measured at the same time each day (first thing in the morning, before coffee, is the most consistent). A gradual downward trend often reflects improving cardiovascular fitness. A sudden or sustained rise without an obvious explanation, like illness or a new medication, is worth paying attention to.
Wearable fitness trackers and smartwatches use optical sensors to estimate pulse continuously, which makes long-term tracking easier. These devices are reasonably accurate for resting measurements but less reliable during high-intensity exercise or if the band fits loosely. For a quick accuracy check, compare the device’s reading to a manual count at your wrist.
