If You Slow Your Resting Heart Rate Can You Slow Down Aging
Having a lower resting heart rate is associated with having a longer lifespan.
Athletes generally have a lower resting heart rate due to their physical fitness.
One study found that the more physically fit you are, the lower the resting pulse. The same study found that even controlling for physical fitness, people with a higher resting heart rate had a shorter life expectancy compared to those with a lower resting heart rate.
So a high resting heart rate is not just a marker of risk, but a risk factor for premature death. The difference between a risk marker and a risk factor is that if you can control the risk factor, you can control the risk.
Why Is A High Resting Heart Rate Dangerous?
If your heart is beating fast 24 hours a day, all that circulatory stress can damage; the elastic fibers supporting your arterial walls causing them to become stiff. Your arteries do not have enough time to relax between beats.
Healthy Hearts Recover Fast
If you are healthy and fit, your heart will recover quickly after exercise, promptly returning to a lower rate. If you are out of shape, however, youre likely to be huffing and puffing after a workout, while your heart rate stays high for a longer time. You can assess this by measuring your heart rate recovery the difference between your beats per minute;when exercising vigorously and your beats per minute;one minute after stopping exercising.
To find your HRR, exercise at a high intensity for a few minutes. High-intensity exercise is when you cant say more than three or four words without significant effort, and are breathing mostly through your mouth, Dr. Sinha says. Stop exercising and immediately measure your heart rate, then again one minute later. A decrease of 15-25 beats per minute;in the first minute is normal. The higher the number of decrease, the fitter you are.
The difference between those two numbers can also tell you something about your risk of dying from a heart attack, Dr. Sinha adds. Studies show that if it drops by 12 or fewer beats in that one minute after exercise, you have a higher risk of death from heart disease.

What Is Your Sleeping Heart Rate
Your heart rate at rest or during sleep measures how fast your heart beats in this state. A good measure of this biomarker is how many heartbeats you record per minute at a relatively passive time, such as immediately you rise before you even get out of bed.
The resting heart rate is of cardinal significance to health. This figure indicates how much exertion your heart muscles have to undertake to maintain blood supply and keep a steady heartbeat.
Hence, with sleeping heart rate unlike with maximum heart rate lower scores are better.
A lower resting heart rate indicates that your heart, heart muscles, and other related circulatory mechanisms are in prime condition. Lower RHR means they dont have to overexert themselves to maintain proper cardiovascular function.
Consequently, the closeness of your resting heart rate to average can often be a valid predictor of your risk factor for heart disease, heart failure, and high blood pressure.
What then, is the perfect resting heart rate? Like with most physiological metrics, it depends.
According to the American Heart Association, barring any underlying medical conditions, the reasonable resting heart rate for most people should fall between 60-100 beats per minute, with healthier people often falling on the lower end of that range.
However, this broad range does not tell the whole story.

Does Your Heart Have A Maximum Number Of Beats
The maximum number of lifetime heartbeats for humans is about 3 billion. But you wont die when you reach a set number of heartbeats. Heartbeats, however, are a marker of your metabolic rate. The faster your metabolic rate , the shorter your lifespan.
For example:
The total number of heartbeats per lifetime is amazingly similar across all mammals. For example, a mouse has; a heart rate of 500 to 600 beats per minute but lives less than two years. At the other extreme, a Galápagos tortoise has a heart rate of about six beats per minute and has a life expectancy of 177 years.
Do the math and the heart of a mouse beats 100 times faster than that of a tortoise. But a tortoise lives 100 times longer than a mouse. Humans, however, have about 60 bpm and have about 3 billion heartbeats per lifetime.
What Can Resting Heart Rate Readings Indicate
Resting heart rate is an indicator of fitness and general health. They are:
- In adults, a lower heart rate is correlated with a higher degree of fitness and a lower incidence of cardiac events, such as heart attacks.
- Highly trained athletes can have an RHR as low as 40. This may be because the lower rate translates to a heart muscle that is stronger and can pump blood more efficiently. Another explanation is that with vigorous exercise, there is the release of nitrous oxide in the hearts blood vessels, which increases the blood supply to the heart.
- However, a consistently higher heart rate has been associated with cardiovascular issues and premature death.
- A 2013 research that studied 3000 men for 16 years found that men with RHR greater than 90 were associated with triple the risk of death when compared to men with RHR below 80.
- An observational study conducted in Norway that looked at 20,000 participants found similar results, even when controlled for factors, such as body mass index and life.

A ‘normal’ Resting Heart Rate May Not Be So Normal After All
ByJoshua A. Krisch05 February 2020
A study of more than 90,000 people with smartwatches reveals that resting heart rate can vary between individuals by up to 70 beats per minute.
Most healthy people experience little variation in their heart rates at rest, but a new study shows that normal resting heart rates can differ between individuals by an astonishing 70 beats per minute.;
The findings challenge the conventional approach to taking this simple vital sign doctors typically check resting heart rate at every visit, but only to make sure it falls in a “normal” range. ;Instead, the new results suggest that monitoring how an individual’s resting heart rate fluctuates over time may tell physicians more about his or her health than comparing a snapshot of his or her heart rate to that of the general population.
“What is normal for you may be unusual for someone else and suggest an illness,” said study co-author Giorgio Quer of the Scripps Research Translational Institute in La Jolla, California. Viewing a person’s heart rate data over the long term “may prove to be a rich source of information” for evaluating their health, Quer said.;

What Does This Tool Help You Learn
This tool will help you find your target heart rate based on your age, resting heart rate, and activity level. Your target heart rate can guide you to how hard you should exercise so you can get the most aerobic benefit from your workout.
Do not use this target heart rate measurement if you are taking medicine that affects your heart rate, such as beta-blockers, calcium channel blockers, or digoxin. Talk to your doctor before you start an exercise program.

What Is Maximum Heart Rate
The maximum heart rate is the highest heart rate achieved during maximal exercise. One simple method to calculate your predicted maximum heart rate, uses this formula:
220 – your age = predicted maximum heart rate
Example: a 40-year-old’s predicted maximum heart rate is 180 beats/minute.
There are other formulas that take into account the variations in maximal heart rate with age and gender. If you are interested in learning more about these more accurate but slightly more complicated formulas please see these resources:

Your actual maximum heart rate is most accurately determined by a medically supervised maximal graded exercise test.
Please note that some medications and medical conditions may affect your heart rate. If you are taking medications or have a medical condition , always ask your doctor if your maximum heart rate/target heart rate will be affected. If so, your heart rate ranges for exercise should be prescribed by your doctor or an exercise specialist.
What Should My Heart Rate Be When I Am Active
When you work out, your heart rate will get higher. This is called your;active heart rate. Active heart rates, like resting heart rates, differ in people and change as you age.Generally, a healthy active heart rate is 60 to 80 percent of your maximum heart rate, or the highest your heart rate should safely go. This is called your maximum;heart rate. A guideline for calculating your maximum heart rate is to subtract your age from 220, like this:220 your age = your maximum;heart rate

How To Measure And Understand Heart Rate
Most people have heard about monitoring their heart rate the speed at which your heart beats for exercising safely and effectively. However, they dont always understand how to measure heart rate or why heart rate measurement is so important.
They are aware that exercise raises the heart rate, but have no real idea about just how much that increase should be. What should your hrv heart rate variability be? How often should your heart rate be elevated? How much should you exercise, for how long, and what will it do to your blood pressure?
To learn what heart rate is optimum for your goals, you must first understand what is heart rate and how it relates to exercise. You should also learn the different methods for accurately identifying your target heart rate.

What Is A Normal Or Resting Heart Rate
There are three general ways to classify;heart rate, 1) normal, 2) fast and 3) slow.
- A resting heart rate is normal between 60-100 beats per minute.
- A resting heart rate is fast at greater than 100 beats per minute.
- A resting heart rate is slow at less than 60 beats per minute.
A resting heart rate predicts longevity and cardiovascular disease, and current evidence suggests that it is also an important marker of outcome in cardiovascular disease, including heart failure. A normal heart rate is generally stated to be between 60-100 beats per minute at rest . However, recent studies have suggested that an ideal resting heart rate is between 50-70 beats per minute. It is well-known that the average resting heart rate for well-trained athletes is between 40-60 beats per minute! A heart rate can change dramatically while sleeping or with daily activity and exercise. Usually, a heart rate will be slower during sleep, faster during daily activities or with exercise, and recover quickly back to a resting rate after exercise. This means your heart has appropriate heart rate variability and recovery, which is associated with good heart health. Your resting heart rate can also be used to estimate how much energy your body uses, or your basal metabolic rate.

How Is An Arrhythmia Diagnosed
Doctors use;several tools to diagnose arrhythmias. It’s very important to know a child’s medical history and give this information to the doctor. The doctor will use the medical history, along with a physical exam, to begin the evaluation.
If an arrhythmia is suspected, the doctor will order an electrocardiogram to measure the heart’s electrical activity. For this painless test, the child will lie down and have small metal tabs fixed to the skin with sticky papers. The electrodes have wires attached to them, which connect to the EKG machine.;The electrical signals from the heart are then briefly recorded, usually for just 10 seconds. This information is sent to a computer, where it’s interpreted and drawn as a graph.
These types of EKG tests might be recommended:
Legs Up The Wall To Reduce Resting Heart Rate
The legs up the wall pose is a therapeutic yoga pose that helps your body and mind relax. To do the Viparita Karani pose:
Try to stay in this pose for 5 minutes. It doesnt need to be perfect. Even having your legs above your heart works if youre relaxed.
Viparita Karani improves circulation as gravity helps blood flow from your legs back to your heart. Because your heart doesnt need to work as hard, your heart rate lowers.

How Other Factors Affect Heart Rate
- Air temperature: When temperatures soar, the heart pumps a little more blood, so your pulse rate may increase, but usually no more than five to 10 beats a minute.
- Body position: Resting, sitting or standing, your pulse is usually the same. Sometimes as you stand for the first 15 to 20 seconds, your pulse may go up a little bit, but after a couple of minutes it should settle down.
- Emotions: If youre stressed, anxious or extraordinarily happy or sad your emotions can raise your pulse.;
- Body size: Body size usually doesnt change pulse. If youre very obese, you might see a higher resting pulse than normal, but usually not more than 100.;
- Medication use: Meds that block your adrenaline tend to slow your pulse, while too much;thyroid medication or too high of a dosage will raise it.
Maximal Heart Rate Test
While Karvonen theory and heart rate reserve are useful and simple to use, they do not always provide an accurate heart rate training zone; they treat everyone as being the same. For a more individualized heart rate training zone, experienced and already fit exercisers can perform a maximum heart rate test, also known as a stress test.
You can perform a maximum heart rate test using a variety of exercise modalities including rowing machines, treadmills and exercise bikes, as well as running or cycling outdoors.
After a suitable warm-up, begin exercising normally and gradually increase your pace. Continue to get faster until you feel you are working as hard as you possibly can. Keep on exercising a little longer until you have to slow down or stop. On completion, immediately take your heart rate, ideally using a heart rate monitor for accuracy. Use the same basic Karvonen calculation as before, but substitute your new maximum heart rate for the age-adjusted one.
Caution: Maximum heart rate tests are for advanced, fit and healthy exercisers only and should not be attempted by anyone else unless under the direct supervision of a doctor.

What Do My Heart Rate Numbers Mean
Your resting heart rate is the number of times your heart beats each minute when youre not active. The normal range is between 50 and 100 beats per minute. If your resting heart rate is above 100, its called tachycardia; below 60, and its called bradycardia. Increasingly, experts pin an ideal resting heart rate at between 50 to 70 beats per minute.
If you want to find out your resting heart rate, pick a time when youre not active, find your pulse, count how many times it beats in 30 seconds, and then double that number. You may want to check it several times throughout the day, or over a week, to average out the number and to look for any irregularities.
Resting heart rates can change from person to person and throughout the day, influenced by everything from your mood to your environment. It rises when youre excited or anxious, and sometimes in response to smoking cigarettes or drinking coffee. More athletic people tend to have lower heart rates.
What Is A Normal Heart Rate
A normal resting heart rate is usually between 60 and 100 beats per minute. Your number may vary. Children tend to have higher resting heart rates than adults.
The best time to measure your resting heart rate is just after you wake up in the morning, before you start moving around or have any caffeine.

How To Lower Your Resting Heart Rate
In general, people who are more fit and less stressed are more likely to have a lower resting heart rate. A few lifestyle changes can help you slow it down:
- Exercise regularly. It raises your pulse for a while, but over time, exercise makes your heart stronger so it works better.
- Eat right. Losing weight may slow your resting heart rate. And studies have found lower heart rates in men who eat more fish.
- Tackle stress. Set aside time to disconnect from electronic devices and relax each day. Meditation, tai chi, and breathing exercises can also help.
- Stop smoking. Itâs one of the best things you can do for your overall health.
