A normal resting heart rate for adults falls between 60 and 100 beats per minute (bpm). That range applies when you’re sitting or lying down, calm, and feeling well. Where you land within that window depends on your fitness level, age, medications, and other factors that shift your baseline up or down.
Resting Heart Rate for Adults
The 60 to 100 bpm range is the standard benchmark used by the American Heart Association, the Mayo Clinic, and the Cleveland Clinic. “Resting” means you’ve been sitting or lying quietly for a few minutes, not right after climbing stairs or drinking coffee. Most healthy adults will find their pulse somewhere in the middle of that range, typically between 65 and 85 bpm.
A resting rate consistently above 100 bpm is called tachycardia. A rate below 60 bpm is technically called bradycardia, though population studies often use a lower cutoff of 50 bpm because many healthy people naturally sit in the 50s without any problems. The clinical threshold matters less than how you feel and whether your heart rhythm is steady.
Heart Rate Ranges for Children
Children’s hearts beat significantly faster than adults’, and the younger the child, the higher the rate. These ranges come from U.S. Department of Health and Human Services pediatric life support guidelines:
- Newborn to 3 months: 85 to 205 bpm while awake, 80 to 160 bpm while sleeping
- 3 months to 2 years: 100 to 190 bpm awake, 75 to 160 bpm sleeping
- 2 to 10 years: 60 to 140 bpm awake, 60 to 90 bpm sleeping
- Over 10 years: 60 to 100 bpm awake, 50 to 90 bpm sleeping
By around age 10, a child’s resting heart rate begins to mirror the adult range. The wide spread in infant rates is normal. Babies’ hearts are smaller and pump less blood per beat, so they compensate with speed.
Why Athletes Have Lower Heart Rates
Endurance athletes often have resting heart rates well below 60 bpm, and this is generally a sign of cardiovascular efficiency rather than a problem. A study published in Circulation monitored 465 endurance athletes with a median age of 23 and found that 38% had a minimum heart rate at or below 40 bpm. A small group (2%) dropped to 30 bpm or lower.
Two things drive this. First, regular endurance training increases the influence of the vagus nerve on the heart, which naturally slows it down. Second, sustained exercise physically remodels the heart’s pacemaker cells, making each beat stronger and more efficient. The heart pumps more blood per contraction, so it doesn’t need to beat as often.
Interestingly, genetics play an independent role. Research shows that inherited traits influence how the heart’s pacemaker responds to training, and some of those same genetic markers may even influence a person’s likelihood of becoming an endurance athlete in the first place. So a low resting heart rate in a fit person reflects both training and biology.
What Affects Your Heart Rate
Your resting heart rate isn’t fixed. It shifts throughout the day and across your life based on several factors:
- Physical fitness: Regular aerobic exercise lowers resting heart rate over time by making the heart more efficient.
- Stress and emotions: Anxiety, excitement, and anger all trigger your body’s fight-or-flight response, which speeds up your heart. Chronic stress can keep your baseline elevated.
- Caffeine and stimulants: Coffee, energy drinks, and nicotine temporarily raise heart rate.
- Medications: Beta blockers, commonly prescribed for high blood pressure and anxiety, slow the heart rate. They can keep your pulse from climbing during exercise the way it normally would, which is worth knowing if you track your heart rate during workouts.
- Body temperature: Fever and hot environments push heart rate up as your body works to cool itself.
- Hydration: Dehydration reduces blood volume, forcing the heart to beat faster to maintain circulation.
- Body position: Standing up quickly can temporarily raise your heart rate as your body adjusts to the shift in blood flow.
Heart Rate During Exercise
When you’re active, your heart rate should climb well above its resting level. The simplest way to estimate your maximum heart rate is to subtract your age from 220. A 40-year-old, for example, has an estimated max of 180 bpm.
From there, exercise intensity breaks into two useful zones. Moderate exercise (a brisk walk, casual cycling) falls at 50% to 70% of your max. For that 40-year-old, that’s roughly 90 to 126 bpm. Vigorous exercise (running, high-intensity interval training) lands at 70% to 85% of your max, or about 126 to 153 bpm. Federal guidelines recommend either 150 minutes of moderate activity or 75 minutes of vigorous activity per week.
These are estimates, not hard boundaries. The 220-minus-age formula is a rough average that can be off by 10 to 15 bpm in either direction for a given person. If you’re on beta blockers or other heart rate-lowering medications, the formula won’t apply to you in the usual way.
How to Check Your Pulse
The easiest place to feel your pulse is at the wrist. 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. Pushing too hard can actually block blood flow and make the pulse harder to detect.
You can also check at the neck by placing your fingertips on one side of your windpipe, in the soft groove just below the jawline. Use gentle pressure here as well.
Before measuring, sit quietly for a few minutes so you get a true resting rate. 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, though this amplifies any counting error. If you notice your pulse feels irregular, skipping beats, or racing while you’re at rest, that pattern is more important to pay attention to than the exact number.
