What is the normal resting heart rate range for an adult?

• A. 40-60
• B. 100-120
• C. 60-100
• D. 120-140

Answer: (C)

Resting heart rate is the number of times the heart beats per minute when you’re at rest, reflecting baseline cardiac function. For most adults, the normal resting range is about 60 to 100 beats per minute. This range represents a balance between heart efficiency and autonomic control. Some well-trained athletes may have resting rates below 60, which can be normal for them due to higher conditioning, but for the average adult 60–100 is considered normal. If resting rates stay consistently above 100, that suggests tachycardia and might indicate factors like fever, dehydration, stress, or other conditions. If rates stay well below 60, especially with symptoms, bradycardia could be a concern.
