The human heart is one of the most remarkable organs in the body. About the size of a fist, it works continuously - day and night - pumping oxygen-rich blood through a network of blood vessels to nourish every cell.
On average, the heart beats around 100,000 times each day, adjusting instantly to the bodyâs needs whether you are resting, walking, or exercising. This powerful muscle is not only essential for survival but also incredibly resilient, capable of strengthening with healthy habits like exercise, good nutrition, and proper cardiovascular support. Its constant, rhythmic work is what keeps the entire body functioning and thriving. ď¸
Here are 9 facts that might help you live a longer and healthier life by understanding and looking after 1 of the 5 most important organs in your body...
1. The Length of Your Heartâs Blood Vessels Is Staggering
If you stretched out all your blood vessels, theyâd extend more than 60,000 miles long and wrap around the world more than twice.
2. Your Heart Weighs Less Than a Can of Soda
Your heart is about the size of two fists and weighs 10 ounces, or slightly less than a can of soda. Each valveâthe parts that open and close to allow blood to flow in and outâis about the size of a half-dollar.
3. A Poor Workout May Signal a Heart Problem
Your workouts not only boost your heart health, they can also serve as your bodyâs âcheck engineâ light.
If you spend a few sessions in a row struggling to run the same pace or complete the same circuit you usually do for no apparent reason, talk to your doctor, as this could signal that your heartâs not quite pumping enough blood, which is an early sign of heart trouble.
4. The Big C Wonât Strike Your Heart
Heart cancer develops so rarely even the Mayo Clinic sees only about one case per year. Thatâs because heart cells stop dividing early, so cancer-causing mutations are less likely to occur.
Still, thatâs not to say that cancer elsewhere in your body canât harm your heart. Other cancers can metastasize, or spread, to your heart. Plus, chemotherapy and other treatments for malignancies can damage its tissue.
5. Laughter Is Good For Your Heart
Laughter balances your stress hormones, reduces inflammation in your arteries, and increases HDL or âgoodâ cholesterol. These effects last at least 24 hours, according to the American Heart Association.
6. You Can Gauge Your Heartâs Health With a Tape Measure
For a quick check of your heart risk, wrap a tape measure around your waist. If it measures half your height or more â say, 35 inches or greater for a 5â10â guyâyour middle makes you prone to problems.
Fat stored in your gutâespecially deep or visceral fat, the stuff surrounding your organsâsecretes hormones and other compounds that boost your chances of heart disease.
7. Your Heart Is Eco-Friendly
More hospitalizations for heart problems occur on days with higher levels of large air particles.
And serious heart attacks strike more people who already have heart disease on bad air days.
8. Your Feet Can Signal an Impending Heart Problem
Another cardiovascular red flag: stepping up a shoe size.
When your heart starts to fail, your body retains water, causing swelling in your legs and feet, Dr. Stewart says. That may make your regular-size shoes feel too tight.
9. Extra Pounds Hurt Your Heart At Any Age
Signs of heart disease â including thickened muscle tissue â have been found in obese kids as young as age 8 by researchers.
Extra weight can weigh down their hearts early, boosting their odds of a cardiac event later in life â and an earlier death.
âHigh grade citrus bergamot - taken daily - is a great way to keep your heart healthy.â
