Monitoring your resting heart rate—the number of times your heart beats per minute while awake, calm, and inactive—can provide valuable information about your overall health, according to medical experts.

The Mayo Clinic defines a normal resting heart rate for adults as ranging from 60 to 100 beats per minute. Athletes or very fit individuals may have rates closer to 40 beats per minute, reflecting a heart that works more efficiently.

Various factors can influence resting heart rate, including age, physical activity, sleep quality, smoking, cardiovascular disease, cholesterol levels, diabetes, stress, anxiety, hormones, body type, and certain medications.

The Cleveland Clinic notes that a high resting heart rate, even if only slightly elevated, may indicate underlying health issues such as anemia, infection, or thyroid problems. Medical professionals advise that if your heart rate consistently exceeds 100 beats per minute despite lifestyle changes, you should consult your doctor.

Experts emphasize that just like strengthening muscles, it takes time for the heart to become stronger through exercise. Harvard recommends gradually increasing workout difficulty to lower resting heart rate and improve heart capacity.

While resting heart rate is not the sole measure of health, it serves as an important marker to watch.
