How many times does the average human heart beat in a lifetime?
At rest, a human heart beats roughly 60 to 100 times a minute, every minute, without ever fully stopping to rest. Multiply that out across an average 70-to-80-year lifespan and the number climbs fast.
Reveal the answer
About 3 billion heartbeats over an average lifetime, give or take, depending on resting heart rate and lifespan. Oddly, most mammals rack up a broadly similar lifetime total of around a billion or so beats; humans just live unusually long for their size.
