Fun Fact Friday: How Many Times Does Your Heart Beat in a Day?
No matter what physical activity you participate in, you’re going to get tired. If you work out, go for a run, or play sports, you might notice that your muscles get tired. It’s necessary to rest your muscles after strenuous exercise. Did you also know that your heart is a muscle? Have you ever noticed how you never have to rest your heart? It keeps pumping blood throughout your body without you even noticing it. How hard does your heart actually work? How many times a day does your heart beat? Read more to find out!
Your body is full of muscles, and your heart is one of the most important ones. The heart is one of the key pieces of the circulatory system. When it beats, it pumps oxygenated blood and nutrients to cells throughout your body. As the blood returns, it carries away waste products.
Have you ever seen a video or diagram of a heartbeat? If you look closely it actually looks like it pumps twice in one pump. This is because the right side of the heart receives the blood from the body and pumps it to the lungs, and the left side receives the blood from the lungs and pumps it to the rest of the body.
When you go to the doctors, they will usually take your pulse to see how hard your heart is working. Your pulse is a measurement of how many times per minute your heart beats. Common areas to find a pulse are where there is a large artery located. These places include the side of your neck, the inside of your wrist, or below your thumb. If you lightly press on these areas you should be able to count how many times your heart beats. You can do a quick calculation by counting how many beats you feel in 15 seconds then multiplying that number by 4 to get a BPM (beats per minute).
An average resting heart rate is between 60 and 100 times per minute. When you exercise your heart rate increases because your body has to pump more oxygenated blood to your cells. If you have an average resting heart rate of 76 BPM this means that your heart will beat at least 4,560 times in 1 hour, and 109,440 times per day! Wow, did you know your heart works that hard? Let’s go further! In 1 year, your heart will beat at least 39,945,600 times, and in an average life expectancy of 80 years, it could beat at least 3,195,648,000 times!
If you’re an athlete in great shape, you could have a significantly lower heart rate. Some athletes have a resting heart rate of only 40 BPM. This all depends on the efficiency of your cardiovascular system. How efficient your cardiovascular system is, depends on a number of factors. One measure of your efficiency is stroke volume. This is the volume of blood pumped per heartbeat. Professional athletes have a larger stroke volume than the “average” person that pumps a greater volume of oxygen throughout your body.
