What is the typical range for a normal adult resting heart rate?

The typical range for a normal adult resting heart rate is indeed 60 to 100 beats per minute (bpm). This range is considered the standard for adults because it reflects the heart's ability to pump blood efficiently while the body is at rest. A heart rate within this range ensures that the organs receive adequate oxygen and nutrients without the heart having to work excessively hard.

In contrast, lower heart rates, such as those in the 40 to 60 bpm range, can indicate bradycardia, which may be normal for some individuals, particularly well-trained athletes, but can be a concern if it leads to symptoms such as dizziness or fainting. Higher resting heart rates, like those in the 100 to 120 bpm and 120 to 140 bpm ranges, may suggest tachycardia, which can occur due to various factors such as stress, illness, or heart conditions, and typically requires medical evaluation if persistent. Thus, 60 to 100 bpm is the benchmark for assessing normal resting heart rates in adults.
