![]() To understand why this is, you need to look at other factors besides just heart rate. A slower heart rate is associated with a slower metabolism, but also with being athletic-yet athletes have faster metabolisms, not slower. Now, you may notice a contradiction there. In effect, everything is slowed down-whether this is worth the tradeoff is a matter of individual preference. A slower metabolism will mean that you’ll have less energy, be less active, and possibly also be more prone to weight gain if you overeat-but since your body is running more slowly, it will age more slowly. ![]() Second, a lower heart rate is associated with a slower metabolic rate. People with a low resting heart rate are far less likely to die of cardiac illness. First and most obviously, a lower heart rate is associated with a healthier heart. The association between a low resting heart rate and lifespan appears to work through at least two distinct mechanisms. For every 20 additional beats per minute of resting heart rate, mortality increases by 30–50 percent. ![]() Studies have consistently shown that a lower resting heart rate, at least down to 40 bpm, is associated with a longer life span, both in comparisons between individuals and between species. In fact, some researchers have suggested that the normal range should be defined as 50–90 bpm, rather than 60–100 bpm, since 50–90 is the range that best characterizes healthy non-athletes. People who are not athletes, but who exercise more than average and stay in good shape, commonly have a low resting heart rate in the 50s without suffering any health problems. Athletes often have heart rates as low as 40 bpm. Remember that 60–100 beats per minute guideline? That was for the average, mostly sedentary person. Will a Low Resting Heart Rate Help You Live Longer? Now, you might ask-is it really a problem if you feel OK? Maybe, but maybe not. However, symptoms usually don’t appear until the heart rate is below 50 bpm.

Bradycardia is usually acquired, rather than congenital, and is more common in older patients. More seriously, it can be caused by a more lasting condition such as an autoimmune disorder, neurological disorder, or heart disease. Sometimes this can be a temporary factor such as drug use-particularly beta blockers-or an electrolyte imbalance. When bradycardia presents with these kinds of symptoms, there will also be some kind of medical issue underlying it. This lack can cause symptoms including dizziness, fatigue, sweating, nausea, and fainting. So should you be worried if your resting heart rate is below 60 beats per minute? Why Bradycardia Is Considered DangerousĪn excessively slow heartbeat can mean that your heart does not deliver enough oxygen and other nutrients throughout your body. In medical terms, a low heart rate is known as bradycardia. ![]() However, many of us in the Spartan community have a low resting heart rate. Most medical organizations recommend that an adult’s resting heart rate should be between 60 and 100 beats per minute.
