Your Heart is Either Racing Toward or Away From A Longer Life

An elephant's heart beats around 30 times a minute. A mouse's heart beats up to 600 times a minute. The elephant can live 60-70 years. The mouse is lucky to see two.

This isn't a coincidence. Across the animal kingdom, one of the clearest patterns in biology is that slower-beating hearts tend to belong to animals with a slower overall pace of life — and a slower pace of life tends to come with a longer one.

Humans are a curious exception to this pattern, and that's actually what makes the human research so interesting. We don't have an elephant's heart rate, yet many of us live just as long, or longer.

What that tells scientists is that our bodies have found other ways to buy us extra time. But within our own species, the same basic principle still holds true: people whose hearts beat more slowly at rest tend to live longer than people whose hearts beat faster at rest, all else being equal.

So what does that mean for you?

It turns out your own resting heart rate — the number of times your heart beats per minute while you're sitting still and relaxed, might be one of the simplest and most accessible clues you have about your own long-term health. You don't need a smartwatch or a lab test to check it. Just two fingers on your wrist and a clock will do.

What Counts as a "Good" Resting Heart Rate?

For most adults, a normal resting heart rate sits somewhere between 60 and 100 beats per minute (bpm). But "normal" and "optimal" aren't quite the same thing.

The research on longevity points toward the lower end of that range — closer to 60 bpm — as the sweet spot associated with better long-term health outcomes.

Roughly speaking:

• Children and teens tend to run a bit higher, often 70-100 bpm
• Most healthy adults sit somewhere in the 60-90 bpm range
• Well-trained athletes can have resting heart rates well below 60 bpm — sometimes even in the 40s — which is a sign of a highly efficient heart, not a problem

If your resting heart rate is a bit higher than 60, that's not something to panic about, for your reference the average is 72. It's simply useful information — a number worth paying attention to and, where possible, working to improve over time. Average is not always best.

The Science: Why a Slower Heart Rate May Mean a Longer Life

The animal comparison at the start of this article is a useful illustration of a broader biological pattern, but the evidence that actually matters for you comes from research on humans specifically, comparing people to other people.

One of the most well-known studies on this topic, the Copenhagen City Heart Study, followed almost 16,700 people for over 35 years. The finding was clear: people with a lower resting heart rate had a lower risk of dying during the study period compared to people with a higher resting heart rate.

Why would this be the case? A few reasons:

1. It reflects how hard your heart is working. A heart that can pump enough blood around your body at a lower rate is doing its job more efficiently — similar to a car engine that can cruise comfortably at low RPM rather than constantly working hard just to keep moving.
2. It reflects your nervous system's balance. Your heart rate is controlled by two parts of your nervous system working against each other — one that speeds things up (useful in a "fight or flight" moment) and one that slows things down (useful for rest and recovery). A lower resting heart rate generally suggests your body is spending more time in that calmer, recovery-focused state.
3. It's linked to overall fitness. Large studies have shown that resting heart rate is a reliable, real-world stand-in for overall cardiovascular fitness, meaning it's not just a number on its own, it's connected to how well your whole cardiovascular system is functioning.

How to Actually Lower Your Resting Heart Rate

The encouraging part of all this is that resting heart rate isn't fixed. It responds to lifestyle, often within weeks.

• Aerobic exercise. This is the single most well-supported way to lower your resting heart rate over time. Regular activity like walking, swimming, cycling, or jogging trains your heart to pump more blood with each beat, meaning it needs fewer beats per minute to do the same job.
• Better, more consistent sleep. Poor sleep places extra strain on your cardiovascular system and nervous system, both of which influence your resting heart rate.
• Managing stress. Since heart rate is so closely tied to your nervous system's state, chronic stress tends to keep your resting heart rate elevated. Simple relaxation practices — slow breathing, time outdoors, even short breaks from screens — can help shift your body out of that "on alert" state.
• Watching your hydration and caffeine intake. Dehydration and excess stimulants both tend to push your heart rate up.
• Being patient. Meaningful change in resting heart rate typically happens gradually, over weeks of consistent habits, not overnight.

Nutritional Support: CoQ10 and Nattokinase

Alongside these lifestyle habits, two natural compounds are commonly discussed in the context of heart and circulatory health using dietary supplements:

CoQ10 (Coenzyme Q10) is a compound your body already produces naturally, and it's found in especially high concentrations in heart muscle cells. That's because heart cells are packed with mitochondria — the tiny structures inside cells responsible for producing energy — and CoQ10 plays a direct role in that energy production process.

Because your heart never stops working, it has an especially high demand for the kind of steady cellular energy CoQ10 helps support. One important thing to keep in mind CoQ10 levels drop as you age.

Nattokinase is an enzyme that has been studied for its role in supporting healthy blood flow and circulation. Efficient circulation matters here too — a heart that doesn't have to fight against poor blood flow can do its job with less effort, which ties back to the whole idea of a heart working smarter, not harder. Nattokinase works ot keep your blon thinner so be aware if you are already on blood thinners and discuss with your doctor.

These are supportive players in the larger picture, not a shortcut around it as sleep, calm  and movement are very important.

The Bottom Line

Your resting heart rate is one of the simplest, most accessible windows you have into your own long-term health. It doesn't require expensive equipment or a trip to a specialist — just a little attention and a willingness to build the habits that support it.

Slower doesn't always mean better in life. But when it comes to your heart at rest, the science suggests it just might lead to a longer life and who does not want that?

So, if you want to plan to live longer, prepare to sleep better, move more, stay relaxed and add dietary supplements like CoQ10 and Nattokinase to your daily ritual.
