What is the normal heart rate for an adult?

The normal heart rate for an adult typically ranges between 60 and 100 beats per minute. This range is well-established and reflects the body's need to maintain adequate blood flow while balancing energy demands during different levels of activity. A heart rate within this range indicates that the heart is functioning effectively to supply oxygen and nutrients throughout the body.

In contrast, if the heart rate falls below 60 beats per minute, it may suggest bradycardia, potentially signaling an issue with the heart's electrical system or other health concerns. Heart rates exceeding 100 beats per minute could indicate tachycardia, which may occur due to stress, exercise, or other medical conditions. The crucial takeaway is understanding that 60 to 100 beats per minute is considered normal for a resting adult, and anything outside this range can warrant further examination by a healthcare provider.
