A resting pulse rate below 60 or above 100 beats per minute (bpm) falls outside the normal adult range and may signal a problem. But “bad” depends on context: a fit runner with a resting pulse of 50 is probably healthy, while someone with a resting pulse of 110 and no obvious explanation needs attention. Understanding where the cutoffs are, what symptoms matter, and what pushes your pulse in either direction will help you make sense of your own numbers.
Normal Resting Pulse for Adults
For adults, a normal resting heart rate sits between 60 and 100 bpm. “Resting” means you’ve been sitting quietly for at least a few minutes, not right after climbing stairs or drinking coffee. Within that range, lower is generally better. A resting pulse in the 60s or 70s typically reflects a heart that pumps blood efficiently without working too hard.
A pulse consistently above 100 bpm at rest is called tachycardia. A pulse below 60 bpm is called bradycardia. Neither is automatically dangerous, but both deserve a closer look if they show up regularly or come with symptoms.
Normal Ranges for Children
Children’s hearts beat faster than adults’, and the younger the child, the faster the normal range. Here’s what to expect:
- Newborn to 3 months: 85 to 205 bpm awake, 80 to 160 bpm asleep
- 3 months to 2 years: 100 to 190 bpm awake, 75 to 160 bpm asleep
- 2 to 10 years: 60 to 140 bpm awake, 60 to 90 bpm asleep
- Over 10 years: 60 to 100 bpm awake, 50 to 90 bpm asleep
A toddler with a pulse of 150 is perfectly normal. The same number in a teenager sitting on the couch is not.
When a Pulse Is Too High
A resting pulse above 100 bpm that isn’t explained by exercise, anxiety, or caffeine is worth investigating. When the heart beats too fast, it doesn’t fill completely between contractions, so it pumps less blood with each beat. Organs and tissues get less oxygen as a result, which is why a rapid pulse often comes with lightheadedness, shortness of breath, or chest discomfort.
Chronic tachycardia left untreated can lead to serious problems: heart failure, blood clots that cause stroke, frequent fainting, and in certain types of rapid heart rhythms originating in the lower chambers of the heart, sudden cardiac death. These aren’t inevitable outcomes, but they explain why a persistently fast pulse isn’t something to shrug off.
Emergency departments regularly see patients whose hearts are beating 160 bpm or higher. If your pulse stays elevated at rest, doesn’t settle on its own within a few minutes, or comes alongside chest pain, difficulty breathing, or near-fainting, that warrants urgent evaluation.
When a Pulse Is Too Low
A resting pulse below 60 bpm is common in endurance athletes and often perfectly healthy. Regular aerobic training remodels the heart’s natural pacemaker and increases the influence of the nerve signals that slow the heart down. The result is a stronger, more efficient pump that moves the same amount of blood with fewer beats. Resting pulses of 40 bpm or even slightly lower are well tolerated in a significant number of trained endurance athletes.
Genetics also play a role. Research published in Circulation found that some people carry inherited traits that naturally produce a slower heart rate, and those traits may actually predispose them toward endurance sports in the first place, because a slower resting rate allows the heart to fill more completely and produce greater output during exercise.
A low pulse becomes concerning when it causes symptoms: dizziness, fatigue, confusion, or fainting. If you’re not an athlete and your resting pulse regularly dips below 60, or if you experience those symptoms regardless of fitness level, it’s worth getting checked. Current guidelines suggest that athletes with a pulse below 30 bpm may need further evaluation even without symptoms, though evidence linking extremely low rates to bad outcomes in athletes is still limited.
What Irregular Rhythm Means
A “bad” pulse isn’t only about speed. The rhythm matters too. A healthy heart beats steadily, like a metronome. If you feel your pulse pausing, skipping, or fluttering, that can indicate an abnormal rhythm. Irregular heartbeats can increase the risk of stroke because blood may pool and clot in parts of the heart that aren’t contracting properly. Occasional skipped beats are common and often harmless, but a pattern of irregular rhythm that persists or recurs deserves attention.
Factors That Shift Your Pulse
Your resting pulse isn’t a fixed number. It fluctuates throughout the day and responds to dozens of variables. Caffeine, nicotine, and decongestants can all push it higher. Stress, pain, fever, and dehydration do the same. On the other side, certain medications deliberately slow the heart. Beta-blockers, commonly prescribed for high blood pressure and anxiety, block the effects of adrenaline and cause the heart to beat more slowly and with less force. If you take one, a resting pulse in the 50s may be expected rather than alarming.
Sleep naturally lowers your heart rate, sometimes well below 60. Hormonal shifts, thyroid conditions, and anemia all affect pulse as well. A single high or low reading after a stressful day or a poor night’s sleep doesn’t necessarily mean something is wrong. The pattern over time is what matters.
How to Measure Your Pulse Accurately
Getting a reliable reading starts with sitting down and resting quietly for a few minutes before you check. The two easiest spots to feel your pulse are the inside of your wrist (the radial artery) and the side of your neck (the carotid artery).
For your wrist, place the tips of your index and middle fingers on the thumb side, in the soft groove between the wrist bone and the tendon. Press lightly. Pushing too hard can actually block blood flow and give you a falsely low count. For your neck, find the groove next to your windpipe on one side and press gently. Never press both sides of your neck at the same time, as this can make you dizzy or cause you to faint. If you have known plaque buildup in your neck arteries, skip the carotid method entirely.
Count the beats for a full 60 seconds for the most accurate result. The shortcut of counting for 15 seconds and multiplying by four works in a pinch but can magnify small counting errors. If your watch or fitness tracker gives you a number that seems off, a manual check is a good way to verify.
Heart Rate During Exercise
Your pulse is supposed to climb during physical activity, and a high number mid-workout isn’t “bad” the way a high resting number is. To estimate your maximum heart rate, multiply your age by 0.7 and subtract that from 208. For a 40-year-old, that comes out to about 180 bpm.
Moderate exercise, like brisk walking, typically puts you at 50% to 70% of your maximum. Vigorous exercise, like running or cycling hard, pushes you to 70% to 85%. Going above 85% of your max for extended periods isn’t recommended for most people and can strain the cardiovascular system. If your pulse shoots unusually high during light activity or takes a long time to come back down afterward, that’s a more meaningful warning sign than the peak number itself.
