What is the normal range for resting heart rate in adults?

The normal resting heart rate for adults is indeed 60 to 100 beats per minute. This range is established based on physiological studies of heart function in healthy adults at rest. A resting heart rate below this range may indicate bradycardia, which could be a sign of enhanced cardiovascular fitness or potential health issues, while a heart rate above this range may suggest tachycardia, which could also be associated with stress, anxiety, or other health concerns.

Heart rate can vary based on several factors including age, fitness level, medications, and overall health status. The typical range of 60 to 100 beats per minute captures the majority of healthy adult populations under normal conditions, allowing for slight variations due to individual differences. It's important for individuals to know their own resting heart rate as a metric of their cardiovascular health, and any persistent deviations from this range could warrant further investigation by a healthcare professional.
