According to a work published in the Scientific Journal Frontier, heart rate variability (HRV) is associated with “exceptional durability”.
The metric was also in Netflix ‘Don’t the, a documentary that focuses on Bryan Johnson, a multimillionaire who was sometimes mentioned forever by controversy.
Unusual, even if the methods of wealthy people can sometimes be, experts seem to believe that HRV indicates health at the level of the population, even if many discuss their relevance in most medical and personal environments.
As early as 2010, the researchers found that “the longevity depends on the maintenance of a good autonomous function, in particular on HRV -PF”, but NHS cardiologists and Harvard Health say it is unclear whether the measurement is actually helpful at an individual level.
So what is the variability of the heart rate and why do some health experts believe that measurement may not be as useful for us as you would think?
What is the variability of the heart rate?
The heart rate variability (HRV) refers to the time variation between heartbeats. It is usually measured in milliseconds and requires that special devices are tracked.
This variation is managed by the autonomous nervous system (ANS), which is known from the “sympathetic and parasympathetic nervous system, which is also known as a mechanism of combat or escape and relaxation reaction.
If you are stressed, in danger or sport, your heart rate is higher, which means that your HRV (the time between strokes) is lower. If you are relaxed and healthy, your HRV tends to be lower because your heart rate is slow.
This adaptation can be healthy because your body has different needs at different times. According to Cleveland Clinic, your HRV sometimes does not adapt to what is best for your body, since conditions such as diabetes, anxiety and asthma can lead to the likeable system to bring out too often high heart frequency witnesses.
This is partly the reason why researchers believe that a high HRV can be an indicator of health and durability. It can indicate that you are not too stressed in good health and get enough sleep.
Why shouldn’t the measurement of HRV always be helpful?
HRV have associated several studies with longevity and health. Why don’t we measure all of our when we practice blood pressure?
First, it is very difficult to do this exactly. And as soon as you have the results, it is difficult to interpret them on an individual level.
An electrocardiogram (EKG) is used in medical environments, although some patients are sent home with monitors. The Cleveland Clinic says: “The majority of the fitness equipment and persecutors carried with the wrist follow their heart rate through their skin. Unfortunately, this means that they are usually not sensitive enough to precisely recognize the variability of the heart rate.”
Dr. Malcolm Finaly, a cardiologist and electrophysiologist at Barts Health, said that the attempt to improve your HRV first could “put the car in front of the horse.
“Instead, it is a case of improvements in your health. Your HRV can change. So don’t do too much what this number is and instead concentrate on getting more movement and eating well.”
The doctor said the metric could “use little” when assessing and treating patients because it “only offers a general picture.
“It was shown that it is a good overall indicator of stress or relaxation level in large groups, but it is not always reliable to correlate with the real stress or relaxation of people.
Harvard Health said that “questions about accuracy, reliability and general usefulness of the persecution of HRV”, which says that his connection to ours (on which many supporters concentrate) need more research.
While HRV’s lessons teach us to manage our stress, remain active, good to eat and get enough sleep, are certainly worthwhile.
