If your resting heart rate is high, your risk of all types of death increases… The higher your heart rate variability, the better you can withstand 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 a well-known fact that exercise strengthens the heart. According to the American Heart Association, moderate intensity exercise causes the heart to beat at 50 to 70 percent of maximum heart rate, and vigorous exercise causes the heart to beat at 70 to 85 percent of maximum heart rate. However, health media ‘Health Digest’ reported that you can tell your health by looking at your heart even when you are resting and not exercising.
When you are not exercising, your heart beats regarding 60 to 100 times per minute. According to Harvard Medical School, a low resting heart rate generally means that you are in a physically healthy state. 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 heart’s efficiency, heart rate variability can show how resilient the body responds to changing situations. The heart beats at 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 of more than 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 a paper published in the academic journal Heart, 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 lung cancer. Another study 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% 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 that the body can withstand stress and adapt. Low heart rate variability may mean your body is currently under stress or might lead to health problems in the future. A study published in the journal Brain, Behavior, and Immunity found that higher heart rate variability was associated with lower levels of inflammation.
According to a study published in Biological Research for Nursing, low heart rate variability doubles the risk of death from any cause and increases the risk of cardiovascular disease by 46 percent.
