The Claim

In nonexercising adults, engaging in a median of 4.6 minutes of vigorous incidental physical activity per day is associated with a 25% lower risk of major cardiovascular events, a 38% lower cardiovascular mortality, and a 24% lower all-cause mortality compared to no such activity.

In plain English

Even if you don't exercise regularly, doing vigorous daily activities like climbing stairs or carrying heavy loads for just a few minutes a day (around 4.6 minutes on average) can cut your risk of heart attacks and strokes by about 25%, lower your chance of dying from heart problems by 38%, and reduce your overall chance of dying in a given period by 24% compared to not doing these activities at all.

See the scientific wording

Even small amounts of vigorous incidental physical activity are associated with substantial cardiovascular risk reduction. In nonexercising adults, a median of 4.6 minutes of vigorous incidental activity per day is associated with a 25% lower risk of major cardiovascular events, 38% lower cardiovascular mortality, and 24% lower all-cause mortality compared to none.

Why this might work

When you do short bursts of vigorous activity like climbing stairs fast or carrying heavy groceries, your heart pumps harder and faster. This pushes more blood through your blood vessels, and the extra pressure on the walls makes the cells that line them produce a message that tells the vessels to relax and widen. This keeps your blood pressure healthy and helps your blood flow smoothly. Doing these small bursts regularly makes your blood vessels more elastic, helps your body use sugar better, and cools down inflammation. All of this together lowers your chance of heart attacks, strokes, and dying early.

    The study found that doing about 4.5 minutes of vigorous daily tasks like stair climbing or fast walking is linked to a noticeably lower chance of heart problems and death, exactly as the claim says.
