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 calmly, not during or right after physical activity. Where you land within that window depends on your fitness level, age, medications, and other factors.
Normal Ranges by Age
Heart rate norms shift dramatically from birth through adolescence. Babies and young children have much faster heart rates than adults because their smaller hearts need to pump more frequently to circulate blood effectively.
- 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 around age 10, children settle into the same 60 to 100 bpm adult range. Notice that sleeping heart rates run lower at every age. If you check your pulse first thing in the morning before getting out of bed, expect it to be at the lower end of your typical range.
Why Athletes Often Have Lower Rates
Endurance athletes and highly active people can have resting heart rates as low as 40 bpm. This isn’t a sign of a problem. A well-conditioned heart is a stronger pump. Each beat pushes out more blood, so the heart doesn’t need to beat as often to meet the body’s demands. In general, a lower resting heart rate signals better cardiovascular fitness.
If you start exercising regularly, you may notice your resting heart rate drop over weeks or months. A decrease of 5 to 10 bpm after consistent aerobic training is common and a useful way to track your fitness progress without any special equipment.
What Pushes Your Heart Rate Up or Down
Your resting heart rate isn’t a fixed number. It shifts throughout the day and from one day to the next based on several factors. Caffeine and nicotine both raise it. So do stress, anxiety, pain, fever, and dehydration. Hot weather and high humidity can push your rate higher because your heart works harder to cool you down. Some medications, particularly those for thyroid conditions, asthma, or ADHD, increase heart rate as a side effect. Others, like beta-blockers prescribed for blood pressure, deliberately slow it.
Body position matters too. Standing up after lying down causes a brief spike as your cardiovascular system adjusts to gravity. For the most consistent reading, check your pulse after sitting quietly for at least five minutes.
When Your Rate Falls Outside the Normal Range
A resting heart rate consistently above 100 bpm is called tachycardia. It can feel like your heart is racing or fluttering, and it sometimes causes dizziness, shortness of breath, or chest discomfort. Temporary spikes from caffeine, stress, or illness are common and usually harmless, but a persistently elevated rate at rest deserves attention.
A resting rate below 60 bpm is called bradycardia. For fit individuals, this is perfectly normal. But if you’re not particularly active and your heart rate sits in the 40s or 50s, especially with symptoms like fatigue, lightheadedness, or fainting, that pattern points to an underlying issue with the heart’s electrical system.
The key distinction is whether an unusual rate comes with symptoms. A heart rate of 55 in someone who runs regularly is a sign of fitness. A heart rate of 55 in someone who feels faint getting up from a chair is a different situation entirely.
How to Check Your Pulse at Home
You don’t need a smartwatch or fitness tracker to measure your heart rate. All you need is a clock with a second hand or a timer on your phone.
Start by sitting quietly for a few minutes. Turn one hand palm-up and place the tips of your index and middle fingers on the inside of your opposite wrist, on the thumb side, in the soft groove between the bone and the tendon. Press gently until you feel a steady pulse. Pressing too hard can actually block blood flow and make the pulse harder to detect. Count the beats for a full 60 seconds.
You can also check your pulse at your neck. Place two fingertips in the groove beside your windpipe on one side. Never press both sides of your neck at the same time, as this can make you dizzy or faint. Use the same light pressure and count for 60 seconds.
For the most accurate baseline, measure your heart rate at the same time each day. First thing in the morning, before coffee and before standing up, gives you the truest resting number. Tracking it over a week or two reveals your personal normal rather than a single snapshot that might be influenced by a stressful afternoon or an extra cup of coffee.
