What Is a Normal Heart Rate? Resting Pulse Ranges by Age

A normal heart rate depends on age, activity level, fitness, medicines, and overall health. For most adults, a resting pulse between 60 and 100 beats per minute is considered normal, while children usually have faster rates that gradually slow with age.

Overview: What is a normal heart rate?

Heart rate is the number of times the heart beats in one minute. It changes naturally throughout the day in response to movement, sleep, emotions, body temperature, and many other factors. When people ask about a “normal heart rate,” they are usually referring to the resting heart rate, which is measured when the body is calm, relaxed, and not exercising.

For most adults, a normal resting heart rate is between 60 and 100 beats per minute. However, this range is only a general guide. Some healthy adults, especially those who exercise regularly, may have a resting heart rate below 60 without any medical problem. In contrast, a heart rate near the upper end of normal may still be healthy depending on age, fitness, medications, and current stress levels.

Children usually have faster heart rates than adults because their bodies are smaller and their metabolism is higher. As children grow, the resting pulse gradually slows. This is why heart rate should always be interpreted in the context of age rather than using one number for everyone.

Heart rate is also different from heart rhythm. A person may have a pulse within the normal range but still have an irregular rhythm. If the pulse feels uneven, suddenly much faster than usual, or much slower than usual, a medical assessment may be needed to rule out issues such as arrhythmia.

Resting pulse ranges by age

Resting pulse rates are usually highest in newborns and infants, then gradually decrease through childhood, adolescence, and adulthood. Exact values can vary slightly among medical references, but the following ranges are commonly used as a practical guide for a resting heart rate:

• Newborns to 1 month: about 70 to 190 beats per minute
• Infants 1 to 11 months: about 80 to 160 beats per minute
• Children 1 to 2 years: about 80 to 130 beats per minute
• Children 3 to 4 years: about 80 to 120 beats per minute
• Children 5 to 6 years: about 75 to 115 beats per minute
• Children 7 to 9 years: about 70 to 110 beats per minute
• Children 10 years and older, adolescents, and adults: about 60 to 100 beats per minute
• Well-trained athletes: sometimes 40 to 60 beats per minute

These ranges are intended for resting conditions. Heart rate normally rises during exercise, excitement, pain, fever, or emotional stress. A pulse checked right after walking up stairs, drinking caffeine, or feeling anxious will not reflect a true resting heart rate.

Because each person has a slightly different baseline, the most useful comparison is often a person’s usual heart rate over time. If someone typically rests in the low 60s and suddenly begins having repeated readings in the 90s without a clear reason, that change may be worth discussing with a doctor even if it still falls within the adult “normal” range.

What can affect heart rate?

Heart rate is influenced by both normal body processes and medical conditions. Physical activity is one of the most obvious factors. During exercise, the heart beats faster to deliver more oxygen to the muscles. After activity stops, the pulse gradually returns to its resting level. In general, people who are more physically fit often have lower resting heart rates because the heart pumps more efficiently.

Emotions and stress hormones can also increase pulse rate. Anxiety, fear, excitement, and pain may all temporarily make the heart beat faster. Other common influences include caffeine, nicotine, alcohol, dehydration, hot weather, fever, and lack of sleep. For this reason, it helps to check pulse after sitting quietly for at least five minutes.

Many medicines can raise or lower heart rate. Examples include stimulants, some asthma medicines, thyroid medication, beta blockers, and certain heart rhythm drugs. Hormonal changes and medical conditions such as anemia, infection, overactive thyroid, and low blood pressure can also affect the pulse. In some cases, structural heart problems or electrical disturbances in the heart may play a role.

Occasionally, a fast heart rate may be linked to an underlying heart or circulation problem such as coronary artery disease or a rhythm disorder, although many cases are caused by temporary and non-dangerous factors. Looking at symptoms, timing, and overall health helps doctors understand whether a heart rate change is expected or needs further investigation.

How to measure heart rate correctly

Heart rate can be measured by feeling the pulse at the wrist or the side of the neck, or by using a smartwatch, fitness tracker, blood pressure monitor, or medical device. To check it manually, a person can place two fingers over the radial artery on the thumb side of the wrist or over the carotid artery on the side of the neck. The number of beats is then counted for 30 seconds and multiplied by two, or counted for a full minute for a more precise result.

For the most accurate resting heart rate, it is best to measure first thing in the morning before getting out of bed, or after sitting quietly for several minutes. The person should avoid measuring immediately after exercise, emotional stress, caffeine, smoking, or a hot shower, since all of these can temporarily raise the reading.

Wearable devices can be useful for spotting trends, but they are not perfect. Movement, poor skin contact, and irregular rhythms can affect accuracy. If a device repeatedly shows a very high, very low, or irregular heart rate, it is wise to confirm the reading manually or with a medical-grade device and seek medical advice if needed.

Keeping a simple record can help. Writing down the heart rate, time of day, symptoms, and possible triggers such as exercise, illness, or caffeine may help a doctor identify patterns. If there are concerns about blood pressure or circulation as well, a doctor may also recommend checking blood pressure and pulse together.

When is a heart rate too high or too low?

In adults, a resting heart rate consistently above 100 beats per minute is called tachycardia, while a resting heart rate below 60 beats per minute is called bradycardia. These terms describe numbers, but they do not always mean disease. For example, sinus tachycardia can happen normally with fever, dehydration, anxiety, or exercise, and bradycardia may be normal in athletes or during sleep.

The key question is whether the heart rate is causing symptoms or reflects an underlying problem. Warning signs can include dizziness, fainting, chest pain, unusual shortness of breath, severe fatigue, confusion, or palpitations. An irregular pulse, sudden episodes of racing heartbeat, or persistent changes from a person’s usual resting rate should also be taken seriously.

Doctors may investigate repeated fast, slow, or irregular heart rates with an electrocardiogram, blood tests, ambulatory monitoring, exercise testing, or echocardiography to check heart structure and function. If there is concern about a rhythm disturbance, further evaluation with an electrophysiology study may sometimes be recommended.

In emergency situations, such as chest pain, collapse, severe breathing difficulty, or new confusion, urgent medical care is important. Even though many heart rate changes are harmless, professional evaluation helps distinguish normal variation from conditions that need treatment.

Ways to support a healthy resting heart rate

A healthy lifestyle can support heart function and help maintain a normal resting pulse. Regular physical activity strengthens the heart muscle so it can pump blood more efficiently. Over time, this often lowers the resting heart rate in a healthy way. Exercise plans should be appropriate for age, fitness, and any medical conditions, and should be discussed with a doctor if symptoms occur during activity.

Good sleep, stress management, and hydration also matter. Poor sleep and chronic stress may keep heart rate elevated. Relaxation techniques such as paced breathing, walking, stretching, mindfulness, and limiting excessive screen time before bed can help the nervous system settle and support a steadier pulse.

Diet and daily habits also play a role. Limiting excess caffeine, avoiding tobacco, and moderating alcohol may reduce unnecessary increases in heart rate. Managing medical conditions such as thyroid disease, anemia, infection, or high blood pressure can also help. Some people benefit from heart-health evaluations such as cardiac check-ups if they have risk factors, family history, or recurring symptoms.

When an abnormal heart rate is related to a treatable cause, addressing that cause often improves the pulse. This may involve adjusting medications, treating dehydration or fever, correcting hormonal problems, or managing a rhythm issue. In selected cases, doctors may consider treatments ranging from medicines to procedures such as catheter ablation for certain abnormal rhythms.

When to see a doctor

Medical advice is appropriate if a person notices a resting heart rate that is repeatedly above 100 or below 60 and this is new for them, especially if they are not an athlete. It is also important to speak with a doctor if the pulse feels irregular, if there are episodes of sudden pounding or fluttering in the chest, or if a wearable device repeatedly flags abnormal readings.

Symptoms should always guide urgency. A doctor should evaluate heart rate changes that are associated with dizziness, fainting, shortness of breath, chest discomfort, marked weakness, or reduced ability to exercise. For babies and children, concerns should be discussed with a pediatrician, since normal heart rate ranges are different by age.

A medical visit may include a review of symptoms, medications, caffeine intake, exercise habits, and family history, followed by a physical examination and basic heart tests if needed. This approach helps identify whether the pulse change is part of normal physiology or a sign of a condition that needs monitoring or treatment.

For people seeking specialist care, Acibadem International’s multidisciplinary teams in JCI-accredited hospitals evaluate and treat heart rhythm and cardiovascular concerns for international patients. The most important step, however, is timely assessment by a qualified healthcare professional whenever symptoms or persistent changes in heart rate appear.

Frequently asked questions

What is a normal resting heart rate for adults?

For most adults, a normal resting heart rate is between 60 and 100 beats per minute. A number within that range is not the whole story, because fitness, age, medications, and symptoms also matter.

Is a resting heart rate below 60 always a problem?

No. A resting heart rate below 60 can be normal in healthy people, especially athletes and during sleep. It becomes more concerning if it is new, persistent, or linked to symptoms such as dizziness, fainting, or unusual fatigue.

Why do children have faster heart rates than adults?

Children and infants naturally have higher heart rates because their bodies are smaller and their metabolism is faster. As they grow, the resting pulse gradually slows and approaches the adult range.

How can someone check their pulse at home?

A person can place two fingers on the wrist or the side of the neck and count the beats for 30 seconds, then multiply by two. For the best resting reading, it helps to measure after sitting quietly for a few minutes or first thing in the morning.

Can anxiety or caffeine raise heart rate?

Yes. Stress, anxiety, caffeine, nicotine, fever, dehydration, and poor sleep can all temporarily increase heart rate. This is why a true resting pulse should be checked when the body is calm and comfortable.

When should a fast or slow heart rate be checked by a doctor?

A doctor should assess a heart rate that is repeatedly very fast, very slow, or irregular, especially if it is different from the person’s usual pattern. Medical attention is particularly important if there is chest pain, fainting, shortness of breath, or severe dizziness.
