Your resting heart rate (RHR) is the number of times your heart beats per minute while you are awake, calm, and not moving. Most healthy adults have a resting heart rate below 90 beats per minute, with the typical range being 60 to 100 beats per minute1 . Measuring your resting heart rate provides a real-time snapshot of how well your heart muscle is functioning and can help identify potential health issues2 . A higher resting heart rate is linked with increased risks of cardiovascular disease and premature death, while a lower resting heart rate often indicates better physical fitness and heart health2 .
Normal Resting Heart Rate Range
The standard clinical range for a normal adult resting heart rate is between 60 and 100 beats per minute (bpm) 3. However, many healthy adults have resting heart rates between 60 and 90 bpm4 . Large population studies show some variation: a US cohort had a mean resting heart rate of 65 bpm, while an Iranian cohort reported a median of 74 bpm, with females generally having higher rates than males (76.6 vs. 71.4 bpm) 53.
Resting heart rate naturally varies between individuals and changes with metabolic demand3 . It tends to decrease with age and is higher in children compared to adults6 3. Athletes and physically fit individuals often have resting heart rates below 60 bpm, sometimes as low as 40 bpm, reflecting a more efficient heart muscle3 2.
Factors influencing resting heart rate include health status, stress, medications, hormonal changes, and ethnicity3 . Lower resting heart rates generally indicate better cardiovascular fitness and reduced risk of cardiac events like heart attacks2 .
Causes of High or Low Heart Rate
Resting heart rate can be influenced by acute and chronic factors such as environmental conditions, medications, underlying health conditions, and lifestyle5 3. Both high and low resting heart rates may signal health concerns depending on the context.
Causes of Tachycardia
Tachycardia is defined as a resting heart rate above 100 bpm3 . It can be caused by:
- Stress and anxiety, which release adrenaline and increase heart rate3 7.
- Fever or infections raising metabolic demand7 .
- Overactive thyroid (hyperthyroidism) stimulating the heart7 .
- Anemia, causing the heart to beat faster to compensate for low oxygen levels7 .
- Certain medications, such as asthma drugs, antidepressants, and some blood pressure medicines3 7.
- Excessive caffeine, alcohol, or stimulant use7 .
- Heart conditions including arrhythmias like atrial fibrillation, coronary artery disease, and heart failure8 7.
- Electrolyte imbalances and dehydration3 7.
Tachycardia may cause symptoms such as chest pain, palpitations, dizziness, fainting, and shortness of breath8 . Some forms can lead to serious complications like stroke, heart failure, or sudden cardiac death if untreated8 .
Causes of Bradycardia
Bradycardia is a resting heart rate below 60 bpm3 . While it can be normal in athletes, it may indicate problems when accompanied by symptoms. Causes include:
- Aging-related damage to the heart’s electrical conduction system9 .
- Heart disease, heart attack, or myocarditis affecting heart tissue9 .
- Hypothyroidism (underactive thyroid) slowing heart rate9 .
- Certain medications such as beta-blockers and calcium channel blockers3 9.
- Mineral imbalances and inflammatory diseases9 .
- Obstructive sleep apnea and congenital heart defects9 .
Symptoms of problematic bradycardia include fatigue, dizziness, fainting, chest pain, and shortness of breath9 . Severe bradycardia can reduce oxygen delivery to the body and may require medical intervention like a pacemaker9 .
“In certain cases, a lower resting heart rate can indicate a higher degree of physical fitness, which is associated with reduced rates of cardiac events such as heart attacks. Conversely, a high resting heart rate may signal an increased risk of cardiac problems in some situations, as a higher number of heartbeats can eventually impair overall heart function.”

How to Measure Resting Heart Rate
Measuring your resting heart rate accurately requires a calm, rested state and proper technique. Resting heart rate should be measured after sitting or lying down quietly for 3 to 5 minutes5 . The best time to check is first thing in the morning before getting out of bed or consuming caffeine2 10.
Common methods include:
- Manual pulse counting: Place your index and middle fingers on the inside of your wrist (below the thumb) or on the side of your neck next to the windpipe. Count the number of beats for 15 seconds and multiply by 4, or count for 30 seconds and multiply by 2 to get beats per minute1 10.
- Automated blood pressure cuffs: Many provide heart rate readings along with blood pressure5 .
- Wearable devices: Smartwatches and fitness trackers can continuously monitor heart rate and provide resting heart rate data. These devices have been validated for accuracy in large studies but may vary by model5 .
Many factors can acutely influence heart rate, including stress, anxiety, environmental conditions, medications, and hydration status5 3. For example, beta-blockers reduce heart rate by blocking adrenaline effects3 . Chronic diseases like COPD and heart disease can cause persistently elevated or lowered heart rates11 3.
“Your resting heart rate—the number of heartbeats per minute while at rest—typically ranges from 60 to 100 beats per minute. Variations outside this range or an irregular heartbeat can indicate underlying health issues. Therefore, regularly measuring your heart rate and understanding your normal range is advisable.”
— Dr. Jorge Romero, Mass General Brigham12
Effective Ways to Lower RHR
Lowering your resting heart rate can improve heart efficiency and reduce cardiovascular risk. Key strategies include:
- Regular physical activity: Exercise strengthens the heart muscle, allowing it to pump more efficiently and lower resting heart rate. The American Heart Association recommends 150 minutes of moderate or 75 minutes of vigorous activity per week5 3.
- Heart-healthy diet: Managing cholesterol and blood pressure through diet supports healthy blood vessels and reduces heart strain3 .
- Stress management: Reducing anxiety and stress lowers adrenaline levels that can elevate heart rate3 .
- Limiting caffeine and alcohol: Both substances can increase heart rate and cause palpitations3 .
- Smoking cessation: Quitting smoking improves cardiovascular health and reduces resting heart rate3 .
- Hydration: Adequate fluid intake can help lower heart rate, especially if dehydration is present5 3.
Medications prescribed by healthcare providers, such as beta-blockers, may also help lower resting heart rate in certain conditions3 .
Lowering your resting heart rate through lifestyle changes like exercise and diet improves heart efficiency and reduces the risk of heart disease and premature death2 3.
Finding Your Maximum and Target Heart Rate
Understanding your maximum and target heart rates helps guide safe and effective exercise.
- Maximum heart rate (MHR) is estimated by subtracting your age from 220. For example, a 50-year-old has an MHR of about 170 bpm3 10.
- Target heart rate during exercise is a percentage of MHR:
- Moderate-intensity exercise: 50-70% of MHR
- Vigorous-intensity exercise: 70-85% of MHR3 10
| Age Range | Maximum Heart Rate (bpm) | Moderate Target (50-70%) | Vigorous Target (70-85%) |
|---|---|---|---|
| 20-30 | 200-190 | 100-140 | 140-170 |
| 30-40 | 190-180 | 95-126 | 133-153 |
| 40-50 | 180-170 | 90-119 | 126-145 |
| 50-60 | 170-160 | 85-112 | 119-136 |
| 60-70 | 160-150 | 80-105 | 112-128 |

Exercising within your target heart rate range improves cardiovascular fitness and helps lower resting heart rate over time3 . If you have heart conditions or take medications, consult your healthcare provider about your ideal heart rate zones10 .
“Some individuals have suffered significant injuries while attempting to check their heart rate during exercise, such as losing balance on a treadmill and falling.”
— Dr. Tracy Stevens, Saint Luke's Mid America Heart Institute13
