1. Your heart beats around 100,000 times per day!
That’s about 35 million beats each year — nonstop from birth to your last day.
2. It pumps about 2,000 gallons of blood daily.
That’s enough to fill a large fire truck — every single day!
3. The heart creates its own electrical impulses.
It can keep beating even if disconnected from the brain (as long as it has oxygen).
4. Your heart is roughly the size of your fist.
For adults, it weighs between 8–12 ounces (200–340 grams) — small but mighty.
5. A woman’s heart beats faster than a man’s.
On average, about 8–10 beats per minute faster.
6. Laughter is good for your heart!
Laughing helps relax blood vessels and increases blood flow, improving heart health.
7. The heart has its own “highway system.”
Your blood vessels — if stretched out — would wrap around the Earth more than twice!
8. Your heartbeat sound comes from valves closing.
That familiar “lub-dub” is the sound of your heart valves opening and snapping shut.
9. Heart cells stop dividing early in life.
Most of your heart muscle cells don’t regenerate like skin cells do.
10. Broken heart syndrome is real!
Strong emotions can trigger heart muscle weakness, called Takotsubo cardiomyopathy — it really can feel like heartbreak.
