If you sit more than 10 and a half hours today, your chance of heart failure rises by

nearly half, but you can reverse

that risk with minutes of simple movement. Hello, and welcome to Dr. Mercola's cellular wisdom.

I'm Ethan Foster, and we're focusing on how everyday sitting quietly strains your heart.

I'm Alara Sky. Together we'll break down new evidence from almost 90,000 adults

showing that prolonged sitting damages cardiovascular health, even when you meet weekly exercise targets.

Modern life funnels you into chairs, office desks, car seats, couches, screens, and that routine

builds silent pressure on your heart. The study we're

discussing used risk-based activity trackers, not questionnaires, so the numbers are precise

rather than estimated. Participants averaged 62 years old, 56% were women, and researchers followed

them for eight years after a week of continuous tracking.

Those who sat beyond 10.6 hours daily faced a 45% higher risk of heart failure and a 62%

higher risk of dying from cardiovascular causes. Importantly, that tipping point applied even to

people completing the customary 150 minutes of moderate to vigorous exercise

each week. Morning workouts did not erase damage accumulated during the rest of the day.

The data showed smaller, but still steady increases, 11% and 15% in irregular heartbeat and

heart attack risk as sitting time climbed.

For heart failure and cardiovascular death, the danger spiked sharply once you crossed the 10.6-hour threshold.

Let's unpack what happens inside you when hours slip by in a chair.
