A normal resting heart rate for most adults falls between 60 and 100 beats per minute (bpm). That said, “normal” varies quite a bit depending on your age, fitness level, and what you’re doing at the time. Your resting rate, the number you get while sitting or lying down but awake, is the most useful baseline to track.
Normal Resting Heart Rate for Adults
The standard range of 60 to 100 bpm applies to adults who are awake, calm, and not exercising. Most healthy people land somewhere in the middle of that window. If you’re physically active or exercise regularly, your resting heart rate will often sit at the lower end, and that’s a good sign. Well-trained athletes can have resting rates in the 40s or 50s because their hearts pump more blood with each beat, so fewer beats are needed.
What matters more than hitting a specific number is knowing what’s typical for you. If your resting heart rate usually hovers around 65 and it suddenly starts showing up at 90 without an obvious reason, that shift is worth paying attention to, even though both numbers fall within the “normal” range.
Heart Rate Ranges for Children
Children’s hearts beat faster than adults’, and the younger the child, the faster the rate. Here’s what to expect by age:
- 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
By the time a child reaches about 10 years old, their resting heart rate aligns with the adult range. Heart rates also drop during sleep at every age, which is completely normal.
Target Heart Rate During Exercise
When you exercise, your heart rate should climb well above your resting number. How high depends on how hard you’re working and how old you are. 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 about 180 bpm.
From there, you can figure out your target zones:
- Moderate intensity (brisk walking, easy cycling): aim for 50% to 70% of your maximum heart rate
- Vigorous intensity (running, fast swimming): aim for 70% to 85% of your maximum heart rate
For that 40-year-old, moderate exercise means a heart rate of roughly 90 to 126 bpm, and vigorous exercise means about 126 to 153 bpm. These are guidelines, not hard cutoffs. If you’re new to exercise, start at the lower end of the moderate zone and build up gradually.
What Makes Your Heart Rate Change
Your heart rate responds to almost everything happening in and around your body. Caffeine and alcohol both raise it. So do stress, anxiety, excitement, and even pain. Hot weather or a rise in body temperature pushes your heart to beat faster to help cool you down. Pregnancy increases resting heart rate because the heart needs to supply blood to the growing fetus.
Certain medications shift your baseline significantly. Beta blockers, commonly prescribed for high blood pressure, slow the heart rate by blocking the effects of adrenaline. Calcium channel blockers also tend to lower it. On the other end, decongestants, some asthma medications, and stimulants can speed things up. If you take any of these, your “normal” may look different from the standard range, and your doctor will have factored that in.
Fitness level is one of the biggest long-term influences. Regular aerobic exercise strengthens the heart muscle, allowing it to pump more blood per beat. Over weeks and months of consistent training, your resting heart rate gradually drops. A lower resting rate generally reflects better cardiovascular fitness.
When a Heart Rate Is Too Slow or Too Fast
A resting heart rate below 60 bpm is called bradycardia. For athletes, this is usually harmless. For others, it can signal a problem with the heart’s electrical system. Symptoms to watch for include dizziness, unusual fatigue (especially during physical activity), confusion, shortness of breath, and fainting or near-fainting. If the slow rate isn’t delivering enough oxygen to the brain and body, those symptoms will show up.
A resting heart rate consistently above 100 bpm is called tachycardia. Short bursts above 100 are perfectly normal during exercise, stress, or after caffeine. But a sustained high rate at rest can strain the heart over time. Symptoms often overlap with bradycardia: lightheadedness, chest discomfort, shortness of breath, and feeling like your heart is racing or pounding.
A rapid or irregular heartbeat paired with chest pain, pressure, or tightness is a red flag. The same goes for a combination of lightheadedness, cold sweats, shortness of breath, or pain spreading to the arms, neck, jaw, or back. These can be signs of a serious cardiac event that needs immediate attention.
How to Check Your Heart Rate
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 bone and the tendon. Press lightly until you feel the beats. Pressing too hard can actually block blood flow and throw off your count.
You can also check at the neck by placing two fingertips in the soft groove just beside your windpipe on either side. This is your carotid pulse, and it’s often easier to find than the wrist pulse.
For the most accurate reading, sit down and rest quietly for a few minutes before you start. Then count the beats for a full 60 seconds while watching a clock. A quicker method is counting for 15 seconds and multiplying by four, though the full minute gives a more reliable number, especially if your rhythm feels uneven. First thing in the morning, before you get out of bed, is the best time to capture your true resting heart rate.
Smartwatches and fitness trackers use optical sensors to estimate heart rate continuously. They’re convenient for spotting trends over time, though they can be less accurate during vigorous movement or if the band is too loose. For a quick spot check, a manual pulse count is still reliable.
