Normal adult resting heart rate ranges from what to what?

• A. 40 to 80 beats per minute
• B. 50 to 90 beats per minute
• C. 60 to 100 beats per minute
• D. 70 to 110 beats per minute

Answer: (C)

A normal adult resting heart rate is typically between 60 and 100 beats per minute. This range represents the heart’s baseline rate when the body is at rest, reflecting the balance of autonomic nervous system input that slows the heart (parasympathetic) and can speed it up (sympathetic). Rates within this window are considered normal for most adults. Values consistently below 60 can indicate bradycardia, which may be normal in well-trained individuals but can signal issues in others. Values consistently above 100 indicate tachycardia and may point to stress, illness, or cardiac concerns. Some people, especially athletes, may naturally have resting rates below 60, which can be normal for them. For an accurate resting measurement, ensure the person is relaxed, seated or lying down, and hasn’t recently exercised, consumed caffeine, or smoked.
