Understanding a Good Resting Heart Rate
Your resting heart rate (RHR) is one of the most accessible metrics for gauging your overall cardiovascular health. It represents the number of times your heart beats per minute while you are at complete rest. A lower RHR generally implies more efficient heart function and better cardiovascular fitness.
What is considered "Normal"?
According to the American Heart Association, a normal resting heart rate for adults ranges from 60 to 100 beats per minute. However, "normal" varies significantly based on age, gender, and physical condition. Elite athletes, for example, may have resting rates as low as 40 bpm.
Heart Rate Reference Chart
Below is a general reference table for men and women indicating average ranges by age group:
Age
Men (Average)
Women (Average)
Athlete (Both)
18-25
70-73 bpm
74-78 bpm
49-55 bpm
26-35
71-74 bpm
73-76 bpm
49-54 bpm
36-45
71-76 bpm
74-78 bpm
50-56 bpm
46-55
72-76 bpm
74-77 bpm
50-57 bpm
56-65
72-76 bpm
74-77 bpm
51-56 bpm
65+
70-73 bpm
73-76 bpm
50-55 bpm
Factors Influencing Your Numbers
Fitness Level: Regular aerobic exercise strengthens the heart, allowing it to pump more blood with each beat, lowering the RHR.
Medications: Beta-blockers tend to lower the pulse, while some thyroid medications can raise it.
Emotions: Stress, anxiety, and excitement can temporarily spike your heart rate.
Body Size: Obesity can put more strain on the heart, potentially raising the resting rate.
Temperature: High heat and humidity can cause a slight increase in heart rate.
How to Measure Accurately
To get the most accurate reading, measure your pulse first thing in the morning before getting out of bed. Place two fingers on your wrist (radial artery) or neck (carotid artery), count the beats for 30 seconds, and multiply by two. Do not drink caffeine or exercise immediately before measuring.
When to See a Doctor
If your resting heart rate is consistently above 100 bpm (tachycardia) or below 60 bpm (bradycardia) without being an athlete, it is advisable to consult a healthcare professional. Other symptoms like dizziness, shortness of breath, or fainting alongside an irregular heart rate warrant immediate medical attention.
