What is the Average Number of Heartbeats Per Day Per Person?

On average, a human heart beats 100,000 times per day — that's about 2.5 billion times in the average life span. The human heart actually starts beating in the womb after about 5 weeks. At this point, it beats about 80 times per minute — about 115,000 times per day. By week 9, a fetus' heartbeat increases to 195 beats per minute — almost 281,000 beats per day. It gradually slows after that.

More Heart Facts:

  • There are about 6 quarts (5.6 liters) of blood in the human body. It makes a full circulation of the body three times per minute — that's almost 12,000 miles (about 19,000 kilometers) of travel per day.

  • The system of blood vessels in the body is more than 60,000 miles (about 96,560 kilometers) long.

  • An adult, human heart is about the size of a fist and weighs 8 to 10 ounces (227 to 283 grams).
