How Resting Heart Rate May Affect Heart Health and Longevity
Did you know your heart moves more than 2,000 gallons of blood through your body every day?
It works continuously, without pause, because even a brief stop would have life-threatening consequences. Since this constant rhythm happens automatically, most of us rarely think about it. But new research suggests that your resting heart rate may reveal more about your long-term health than you realize.
A recent study found that men in their 50s with a resting heart rate of 75 beats per minute or higher were twice as likely to develop heart disease within 11 years compared with men whose resting heart rate was 55 bpm or lower.
Researchers tracked 798 men born in 1943 in Gothenburg, Sweden, over a period of more than 20 years, from 1993 to 2014. The participants were divided into four categories based on resting heart rate:
- 55 bpm or lower
- 56 to 65 bpm
- 66 to 75 bpm
- More than 75 bpm
What the Study Found
After reviewing 21 years of data, the researchers reported a clear pattern. Among men between the ages of 50 and 60, those whose heart rates remained stable were nearly 50% less likely to develop heart disease before age 71 than those whose heart rates increased over time.
The findings also showed that, between ages 50 and 60, each increase of one beat per minute was linked to a 3% higher risk of death during the following 11 years.
These results suggest that even small changes in resting heart rate may matter when it comes to future cardiovascular risk.
What Is Considered a Normal Resting Heart Rate?
A normal resting heart rate usually falls between 50 and 100 beats per minute. Genetics can play a role in where your number naturally sits, but daily habits also have a major influence.
People with a resting heart rate of 75 bpm or higher in the study were also more likely to:
- Smoke
- Be less physically active
- Experience stress
This points to an important takeaway: the same lifestyle habits that support overall health can also help lower resting heart rate.
Why These Results Should Be Viewed Carefully
The study focused only on men over 50, so the findings cannot automatically be applied to everyone.
As Ashleigh Li, a cardiac nurse at the British Heart Foundation, explained, more evidence is needed to determine whether the same connection exists for women and for people of all age groups.
Even so, the results are meaningful and highlight why it is worth paying attention to heart rate over time.
Why Monitoring Your Heart Rate Matters
Checking your resting heart rate regularly may help identify potential heart problems early. A rising heart rate can be a warning sign that the heart is not pumping blood as efficiently as it should.
When the heart becomes less efficient, it must beat faster to move the same amount of blood through the body. A stronger heart, by contrast, can do the same job with fewer beats.
This is why noticing a faster resting heart rate in yourself, an older friend, your father, or your grandfather should not be ignored.
How to Support a Healthier Heart
Because the heart is a muscle, one of the best ways to strengthen it is through regular training. Healthy lifestyle choices can improve heart function and may help reduce resting heart rate over time.
Key habits include:
- Exercising regularly
- Eating a balanced, heart-friendly diet
- Managing stress
- Avoiding smoking
- Staying physically active every day
Final Thoughts
Your resting heart rate is more than just a number. It can offer useful clues about your heart health and may even be connected to longevity. While more research is needed to confirm how these findings apply across different ages and sexes, keeping track of your heart rate and maintaining healthy habits could make a meaningful difference in the long run.
