5 fascinating heart facts for Valentine’s Day

Valentine’s Day is all about hearts — on cards, in candy boxes, and maybe even skipping a beat for someone special.

But beyond the romance, the human heart is an absolute powerhouse, beating about 100,000 times a day to keep us going. In the spirit of the holiday, here are five facts about the heart that go beyond love and into science, straight from the experts at UW Medicine.

1. Cardiologists prioritize sleep for a healthy heart

Doctors who specialize in heart health practice what they preach, especially when it comes to sleep. Cardiologists emphasize that getting at least seven hours of rest each night helps regulate blood pressure, reduce stress, and improve overall heart function.

2. Heart palpitations are often harmless — but not always

That fluttering or racing heartbeat can feel unsettling, but in most cases, heart palpitations are caused by stress, caffeine, or dehydration. However, if palpitations come with dizziness, chest pain, or fainting, they could signal a more serious condition that requires medical attention.

3. A few minutes of exercise can make a big impact

You don’t need a gym membership to boost heart health. Short bursts of activity, known as “exercise snacking,” can be just as beneficial. Whether it’s a quick set of squats or a brisk walk, these small movements can improve cardiovascular fitness and lower the risk of heart disease.

4. Trouble in the bedroom could signal heart disease

Erectile dysfunction (ED) isn’t just about intimacy — it can be an early warning sign of heart disease. Since ED is often linked to poor blood flow, it may indicate underlying vascular issues that could lead to heart problems down the road. Cardiologists recommend talking to a doctor if ED becomes a persistent issue.

5. A broken heart is a real medical condition

Heartbreak isn’t just emotional — it can be physical, too. “Broken heart syndrome,” or Takotsubo cardiomyopathy, is a temporary heart condition triggered by extreme stress or grief. It can mimic the symptoms of a heart attack but usually resolves with time.

This Valentine’s Day, while you celebrate love, don’t forget to show your heart some love, too.
