People who walk 10,000 or more steps a day have a 55% lower relative risk of dying from any cause than those who walk fewer than 7,000.
See the scientific wording
Taking 10,000 or more steps per day is associated with a 55% lower RELATIVE risk of all-cause mortality (hazard ratio 0.45, 95% CI 0.25–0.81) compared with taking fewer than 7,000 steps per day, corresponding to an ABSOLUTE risk difference of about 41 fewer deaths per 1,000 people over approximately 11 years.

Cohort StudyHuman2021
The study found that participants in the high step group (≥10,000 steps/day) had a significantly lower hazard of all-cause mortality compared to the low step group (<7,000 steps/day), with an absolute risk difference of 41 fewer deaths per 1,000 people over the follow-up period.

That doesn't mean it's settled — it just means no study has tested the opposite.
Quality-weighted scoring: we follow the GRADE framework — each study is rated High, Moderate, Low, or Very Low based on study design, methodology rigor, and risk of bias. A single high-quality RCT can outweigh several weaker observational studies.
Scores reflect study quality, not just count.
Walking makes your leg muscles squeeze and relax over and over. That squeezing pushes blood through your arteries faster and stretches the artery walls. The stretched walls release a gas called nitric oxide that opens the arteries wider, so blood pressure drops. At the same time, the working muscles pull sugar out of the blood without needing much insulin, so blood sugar stays lower. With lower pressure and lower sugar, the fatty plaques inside arteries grow more slowly and are less likely to crack open. Fewer cracked plaques means fewer heart attacks and strokes, so people live longer.

Mechanism
1 studyWalking over and over makes the leg muscles squeeze blood forward and makes the artery walls stretch, which releases a widening gas called nitric oxide and lowers blood pressure. The same working muscles also pull sugar out of the blood, so blood sugar stays lower. Lower pressure and lower sugar mean the fatty patches inside arteries grow more slowly and are less likely to crack, so fewer people die from heart attacks and strokes. A second route works through body fat: less fat means fewer irritating signals, which also keeps arteries calmer and patches more stable.

With lower pressure and lower sugar, the fatty plaques inside arteries grow more slowly and are less likely to crack open. Fewer cracked plaques means fewer heart attacks and strokes, so people live longer.
Rhythmic contraction and relaxation of lower-limb skeletal muscle compresses deep veins and propels blood back to the heart, increasing venous return and cardiac output and raising the velocity of blood flow through the arterial tree.
The faster, smoother flow raises laminar shear stress on the inner lining of arteries, which mechanically activates endothelial nitric oxide synthase in endothelial cells.
Activated endothelial nitric oxide synthase produces nitric oxide, which diffuses into the underlying smooth muscle and triggers relaxation, widening the vessel lumen and lowering peripheral vascular resistance and resting blood pressure.
Contracting muscle fibers deplete local ATP, activating AMP-activated protein kinase, which drives glucose transporter type 4 to the muscle cell surface and increases insulin-independent glucose uptake, lowering circulating glucose and insulin levels.
Lower resting blood pressure and lower circulating glucose reduce mechanical and oxidative injury to the arterial wall, slowing the deposition of lipid and fibrous material that forms atherosclerotic plaque.
Slower plaque growth and a more stable, less inflamed plaque surface reduce the probability of plaque rupture and thrombotic occlusion, decreasing the occurrence of myocardial infarction, ischemic stroke, and heart failure and thereby lowering all-cause mortality.
Less supported by current evidence, but not ruled out
Extra body fat, especially around the belly, leaks chemical signals that keep the whole body slightly inflamed. That constant inflammation damages artery walls and makes fatty plaques unstable. Walking every day burns energy, so fat stores shrink, and shrinking fat stores release fewer of those irritating signals. With less irritation, arteries stay healthier, plaques are less likely to break open, and fewer people die from heart attacks and strokes.
Sustained daily walking increases total energy expenditure and creates a negative energy balance that mobilizes triglycerides from visceral and subcutaneous adipose tissue.
Shrinking adipose tissue mass reduces the number and activity of adipose-resident macrophages and decreases secretion of interleukin-6, tumor necrosis factor-alpha, and other pro-inflammatory cytokines.
Lower circulating cytokine levels reduce hepatic production of C-reactive protein and diminish oxidative stress and adhesion-molecule expression on the arterial endothelium.
Reduced endothelial inflammatory activation preserves the fibrous cap of atherosclerotic plaques and lowers the rate of plaque rupture and superimposed thrombosis.
Fewer atherothrombotic events reduce fatal myocardial infarction and stroke, lowering all-cause mortality.
