What Should My Pulse Be? Normal Ranges by Age

A normal resting pulse for adults falls between 60 and 100 beats per minute (bpm). That range applies when you’re awake, calm, and haven’t been moving around. Where you land within it depends on your fitness level, age, medications, and other factors. A pulse closer to the lower end generally signals a more efficient heart.

Normal Resting Pulse by Age

Children’s hearts beat faster than adults’ because their hearts are smaller and need to pump more frequently to circulate blood. Here’s what to expect at different ages:

  • Newborn to 3 months: 80 to 160 bpm
  • 3 months to 2 years: 75 to 160 bpm
  • 2 to 10 years: 60 to 90 bpm
  • Over 10 years and adults: 50 to 90 bpm

These ranges reflect resting or sleeping values. A child’s pulse will naturally spike much higher during play or crying, and that’s completely normal. By the teenage years, heart rate settles into the adult range of 60 to 100 bpm.

What a Lower Resting Pulse Means

A resting pulse on the lower end of the range usually means your heart is strong enough to pump more blood with each beat, so it doesn’t need to beat as often. Highly fit endurance athletes can have resting heart rates around 40 bpm, which would be abnormally low for a sedentary person but is perfectly healthy for someone with a well-conditioned cardiovascular system.

If you’re not particularly active and your resting pulse is consistently below 60, it doesn’t automatically mean something is wrong. Some people naturally run lower. But if a low pulse comes with dizziness, fatigue, or fainting, that combination is worth getting checked out. A pulse consistently above 100 at rest, without an obvious explanation like stress or caffeine, also deserves attention.

Factors That Raise or Lower Your Pulse

Your resting heart rate isn’t a fixed number. It shifts throughout the day and can change over weeks or months depending on what’s happening in your life and body.

Things that push your pulse higher include caffeine, nicotine, sugar, stress, depression, and illness (even a common cold or flu). Smoking cigarettes elevates resting heart rate on its own. Certain medications also speed the heart up, including stimulant medications used for ADHD and some antidepressants.

On the other side, medications like beta blockers and calcium channel blockers (commonly prescribed for blood pressure) slow the heart rate down. Regular aerobic exercise also lowers your resting pulse over time as your heart becomes more efficient. Dehydration can raise it because your blood volume drops and your heart compensates by beating faster.

Your Pulse During Exercise

When you’re working out, your pulse should be higher than at rest. How high depends on the intensity you’re aiming for. Exercise heart rate is typically described as a percentage of your maximum heart rate.

The simplest way to estimate your maximum heart rate is to subtract your age from 220. So a 40-year-old would have an estimated max of 180 bpm. That said, this old formula can underestimate the true max by up to 40 beats per minute in older adults. A more accurate formula, developed from testing over 3,300 healthy adults at the Norwegian University of Science and Technology, is 211 minus 0.64 times your age. For that same 40-year-old, the updated estimate would be about 185 bpm.

Once you know your estimated max, you can figure out where your pulse should be for different goals:

  • Moderate intensity (60% to 70% of max): Good for building endurance, burning fat, and general fitness. You can hold a conversation at this level.
  • Moderate to high intensity (70% to 80% of max): Improves cardiovascular fitness more aggressively. Talking becomes harder.
  • High intensity (80% to 90% of max): Builds speed and power. Sustainable only for shorter intervals.
  • Very high intensity (90% to 100% of max): All-out effort. Only maintainable for brief bursts.

For most people looking to improve general health, keeping your pulse in the 60% to 80% range during exercise is the sweet spot.

How to Check Your Pulse

You can measure your pulse at two easy-to-find spots: your wrist or the side of your neck.

For a wrist reading, turn one hand palm-up and 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. For a neck reading, place the same two fingertips in the soft groove next to your windpipe on one side. Don’t press too hard on the neck, as that can actually slow the pulse and give you an inaccurate count.

Once you feel the beat, count for a full 60 seconds for the most accurate result. If you’re in a hurry, you can count for 15 seconds and multiply by four. To get a true resting heart rate, check it first thing in the morning before you get out of bed, or after sitting quietly for at least five minutes. Checking right after climbing stairs or drinking coffee will give you a number that doesn’t reflect your baseline.

Tracking Changes Over Time

A single pulse reading is a snapshot. The real value comes from tracking your resting heart rate over weeks and months. If you start exercising regularly, you’ll likely see your resting pulse gradually drop as your heart gets stronger. A slow, steady decline is one of the most reliable signs that your cardiovascular fitness is improving.

A sudden or sustained increase in your resting heart rate, on the other hand, can signal that your body is under stress. Overtraining, poor sleep, dehydration, or the onset of an illness can all show up as a higher resting pulse before you notice other symptoms. Many fitness trackers and smartwatches log this automatically, making it easy to spot trends without manually counting beats every morning.
