An adult’s normal resting heart rate should be between 60 and 100 beats per minute. And, according to new research published in the Journal of the American Medical Association, increases in your resting heart rate over time may mean a greater risk of dying of heart disease. The study looked at 30,000 men and women without any known heart disease and measured their resting heart rate over a 10-year period. The participants whose heart rate was less than 70 beats per minute at the first measurement and more than 85 beats per minute at the next measurement were more likely to die from heart disease or other causes after 12 years of follow-up. Ulrik Wisloff, the study’s lead author, says healthy adults should have a resting heart rate of about 70 beats per minute. If it increases more than 10 beats, it may be time to talk to a doctor.
