Answer: Your heart beats about 100,000 times in one day and about 35 million times in a year. During an average lifetime, the human heart will beat more than 2.5 billion times.

4320 times

Your adult heart beats about 100,000 times a day. That’s at least one beat every second, or 60-100 times a minute, according to the American Heart Association. For people whose heart rate is closer to 60 beats per minute, that’s about 86,000 times a day.

Martin Brady holds the Guinness world record for the slowest heart rate with a certified rate over a minute duration of 27 BPM. Professional cyclist Miguel Indurain had, during his career, a resting heart rate of 28 BPM.

“This blue whale had heart rates ranging from 2 bpm to 37 bpm, which is more than an order of magnitude difference — 10-fold,” Goldbogen tells Claire Cameron at Inverse. “In comparison, human heart rates might typically range from 60 bpm to 200 bpm, which is a much lower range, just over a 3-fold difference.”

Eat a healthy, balanced diet: Eating a varied diet rich in fruits, vegetables, lean proteins, nuts, and legumes can help to improve the health of the heart, as well as overall health. Foods and supplements rich in antioxidants and healthy fats can lower blood pressure and make it easier for the heart to pump.

For most people, a heart rate of 60 to 100 beats a minute while at rest is considered normal. If your heart beats less than 60 times a minute, it is slower than normal. A slow heart rate can be normal and healthy. Or it could be a sign of a problem with the heart’s electrical system.
