Pulse is one of the simplest indicators that can help monitor heart activity. When checking their health at home, many people ask: what is a normal heart rate, is the normal heart rate for adults different from that of children, and how are pulse and blood pressure related?
In reality, there is no single number that applies to everyone. Heart rate varies depending on age, physical activity, emotional state, and overall health. Therefore, it is important to understand how to interpret heart rate readings rather than focusing on a single measurement.
What Is a Normal Heart Rate?
Pulse, or heart rate, refers to the number of times the heart beats in one minute and is typically measured in beats per minute (bpm).
For most healthy adults, a resting heart rate of approximately 60–100 beats per minute is considered a typical range. Resting heart rate should be measured when the body is relaxed and not immediately after exercise or under the obvious effects of factors such as stress, caffeine, or fever.
However, healthy and physically fit individuals may have a resting heart rate below 60 bpm without necessarily having a medical problem. Conversely, a heart rate between 60 and 100 bpm does not automatically mean that a person’s cardiovascular health is completely normal.
Therefore, when assessing a normal heart rate, it is important to consider symptoms, the circumstances in which the measurement was taken, and the person’s overall health.
What Is a Normal Heart Rate by Age?
Heart rate differs between children and adults. Younger children generally have higher heart rates because of their physiological characteristics and the body’s circulatory demands. As children grow, their resting heart rate generally decreases.
Normal Heart Rate in Children
The adult range of 60–100 bpm should not be applied to young children.
According to the American Heart Association, resting heart rate varies considerably by age. Infants may have an average resting heart rate of approximately 100–190 bpm, while older children and teenagers may have resting heart rates of around 60–100 bpm.
Therefore, if parents want to know what is a normal heart rate for their child, the child’s exact age and the circumstances of the measurement should be considered rather than applying a single fixed threshold.
A child’s heart rate may increase when they are crying, running, have a fever, or feel anxious, and may decrease during sleep or relaxation. Some variations in heart rate associated with breathing may also be normal in healthy children.
Normal Heart Rate in Adults
For most adults, a resting heart rate between 60 and 100 bpm is considered a typical range. People who exercise regularly or have a high level of physical fitness may have a lower resting heart rate without necessarily having an underlying medical condition.
More importantly, heart rate should be measured while resting and monitored over time. A single reading is not sufficient to determine a person’s cardiovascular health.
Normal Heart Rate in Older Adults
Older age does not necessarily mean that resting heart rate must fall within a completely different range from that of other adults. Many healthy older adults continue to have resting heart rates within the typical adult range.
However, older adults may be more likely to have underlying medical conditions or take medications that affect heart rate. Therefore, if the heart rate changes significantly from its usual level or symptoms such as dizziness, fainting, shortness of breath, or chest pain occur, medical evaluation is recommended.

What Is a Normal Heart Rate During Exercise?
Resting heart rate ranges should not be used to evaluate heart rate during exercise.
During physical activity, the heart needs to pump more blood to deliver oxygen to the muscles, so the heart rate naturally increases. The extent of this increase depends on exercise intensity, age, fitness level, and overall health.
The American Heart Association uses the estimated maximum heart rate of 220 minus age as one reference for determining a target heart rate range during exercise. For moderate-intensity activity, the target zone is generally about 50–70% of estimated maximum heart rate; for vigorous-intensity activity, it is approximately 70–85%. These figures are general guidelines rather than rigid limits that apply to everyone.
For example, for a 40-year-old person, the estimated maximum heart rate using this formula is approximately 180 bpm. The appropriate target heart rate during exercise can then be estimated based on the relevant percentage range.
People with cardiovascular disease or those taking medications that affect heart rate should consult a healthcare professional to determine an appropriate level of physical activity.
What Factors Can Affect Heart Rate?
Even in people without heart disease, heart rate can change throughout the day.
Factors that commonly affect heart rate include:
- Physical activity or exercise.
- Stress, anxiety, or strong emotions.
- Body temperature and fever.
- Body position.
- Caffeine and certain stimulants.
- Medications.
- Physical fitness level.
- Sleep and time of day.
- Existing health conditions.
Therefore, measuring your pulse immediately after climbing stairs, drinking coffee, or experiencing an emotional situation can produce a significantly different result from measuring it while resting in the morning.
How to Measure Your Pulse Accurately at Home
To determine what is a normal heart rate for you personally, it is important to measure your pulse under appropriate conditions.
Ideally, check your heart rate in the morning after adequate sleep, before drinking coffee, and while your body is relaxed. The American Heart Association notes that the pulse can be checked at the wrist or at other locations, such as the inner elbow, side of the neck, or top of the foot.
To measure your pulse at the wrist:
- Sit or lie down and relax for several minutes.
- Place your index and middle fingers on the inner side of your wrist, near the base of the thumb.
- Press gently until you feel the pulse.
- Count the number of beats for 60 seconds to obtain your heart rate in beats per minute.
- Record the result and time of measurement to monitor changes over time.
Avoid pressing too firmly on the carotid artery in the neck when checking your pulse yourself, as this may trigger a reflex that lowers blood pressure and can cause dizziness or fainting in some people.
Are Pulse and Blood Pressure the Same?
Pulse and blood pressure are two different measurements.
Heart rate tells you how many times the heart beats per minute, whereas blood pressure measures the force of blood pushing against the walls of the arteries.
Both are related to cardiovascular function, but one cannot be used as a substitute for the other. A person may have a heart rate within the typical range while still having high or low blood pressure.
Therefore, when monitoring cardiovascular health, it is important not to focus solely on heart rate while overlooking blood pressure and other cardiovascular risk factors.
When Should an Abnormal Heart Rate Be Checked?
One heart rate reading that is higher or lower than usual does not necessarily indicate a medical problem. More important factors include persistent or recurrent changes, particularly when accompanied by symptoms.
Medical evaluation should be considered if:
- Your resting heart rate is consistently unusually high or low compared with your usual level.
- Your heart rate changes significantly without an obvious reason.
- Your pulse feels irregular or seems to skip beats.
- You experience dizziness or lightheadedness.
- You feel short of breath or have reduced exercise tolerance.
- You experience chest pain or discomfort.
- You faint or feel as though you are about to faint.
If an abnormal heart rate occurs together with chest pain, severe shortness of breath, fainting, or rapidly worsening symptoms, seek urgent medical attention.
Does a Lower Heart Rate Mean Better Health?
Not necessarily.
Some healthy people may have a low resting heart rate because of a high level of physical fitness without having any health problems. However, a very low heart rate in someone who has symptoms may require medical evaluation.
Similarly, a higher heart rate does not always mean that a person has heart disease. What matters is the heart rate, the circumstances in which it was measured, associated symptoms, and the underlying cause.
Therefore, do not try to lower or increase your heart rate with medication or unproven methods simply to reach a specific number.
So, what is a normal heart rate? For most adults, a resting heart rate of approximately 60–100 beats per minute is considered a typical range. However, children generally have higher heart rates, with reference ranges varying by age. Athletes and physically fit individuals may also have lower resting heart rates while remaining healthy.
More important than a single number is your usual heart rate pattern and whether you experience any associated symptoms. If your heart rate changes persistently, becomes irregular, or is accompanied by dizziness, shortness of breath, chest pain, or fainting, medical evaluation is recommended to identify the underlying cause.
Monitoring your pulse and blood pressure correctly is a simple step that can help you take a more proactive approach to maintaining cardiovascular health.
