Association of new Life's Essential 8 with biological aging among the national health and nutrition examination surveys.

Summary: Imagine if your body had its own internal clock that ticked faster or slower depending on your daily habits. The American Heart Association created a checklist called "Life's Essential 8" to measure heart health. Researchers looked at over 17,000 adults to see if scoring high on this checklist could slow down their body's internal clock. They found out it does! People with better heart health habits—like eating well, staying active, and getting good sleep—actually had a younger "biological age" compared to their real age. In short, taking care of your heart helps keep your whole body younger.
