#22 The Human Heart Beats About 100,000 Times In A Day
A healthy heart beats an average 80 times per minute, 115,200 times in a day and about 35 million times in a year. The heart beats an unbelievable 3 billion times during an average lifetime of a healthy human being.
A person’s heart is roughly the size of their fist. The sound that we hear while it beats is caused by the opening and closing of valves. An increased heartbeat, known as palpitation, is common when you’re working our or stressed. However, frequent palpitations may be a sign of an underlying health condition.
