The higher your heart rate variability, the better your ability to tolerate stress.

Resting heart rate and heart rate variability not only indicate current health, but can also predict future health and longevity. [사진= 게티이미지뱅크]It is well known that exercise strengthens the heart. According to the American Heart Association, moderate-intensity exercise makes the heart beat at 50-70% of maximum heart rate, while vigorous exercise makes the heart beat at 70-85% of maximum heart rate. However, health media “Health Digest” reported that you can evaluate your health by looking at your heart even when you are resting and not exercising.
When you’re not exercising, your heart beats about 60-100 times per minute. According to Harvard Medical School, a low resting heart rate generally means you are in good physical health. Conversely, a higher resting heart rate means the heart has to work harder to pump blood through the body.
Just as resting heart rate can measure the efficiency of the heart, heart rate variability can show the body’s resilience to respond to changing situations. The heart beats a constant number of times per minute, but there is some variation in the time between successive beats. Heart rate variability measures these changes.
Resting heart rate and heart rate variability not only indicate current health, but can also predict future health and longevity.
A study published in the Canadian Medical Association Journal found that higher resting heart rates were associated with an increased risk of death from all causes and cardiovascular disease. Specifically, for every 10 beats per minute increase in resting heart rate, the risk of death from all causes increased by 9% and the risk of death from cardiovascular disease increased by 8%. People with a resting heart rate above 80 beats per minute had a 45% higher risk of death from all causes and a 33% higher risk of death from cardiovascular disease.
According to an article published in the academic journal Heart, a high resting heart rate was associated with an increased risk of death not only from heart disease but also from various types of cancer, such as breast, colon, kidney and lungs. Another study published in the same journal followed men for 21 years and looked at how their resting heart rate changed. The results showed that men whose resting heart rate remained stable had a 44 percent lower risk of cardiovascular disease than men whose resting heart rate increased.
Unlike a high resting heart rate, high heart rate variability is a good thing. This is because it means the body can resist stress and adapt. Low heart rate variability may mean your body is currently under stress or could lead to health problems in the future.
According to a study published in Biological Research for Nursing, low heart rate variability doubles the risk of death from all causes and increases the risk of developing cardiovascular disease by 46%.
Additionally, a study published in the journal Brain, Behavior, and Immunity found that greater heart rate variability was associated with lower levels of inflammation.
