Want 39 Percent Lower Risk of Cardiovascular Death?

People who regularly climbed stairs had a 39 percent lower risk of dying from cardiovascular disease and a 24 percent lower risk of dying from any cause than people who climbed less. Those are pooled results from nine studies covering 480,479 adults, ages 35 to 84, followed a median of 14 years. Fifty-three percent were women. The analysis, published in the American Journal of Cardiovascular Drugs and led by Vassilios Vassiliou at the University of East Anglia’s Norwich Medical School, also associated stair use with fewer major events: heart attack, stroke, and heart failure. The studies were mostly observational. They do not prove the stairs caused the longer lives.

Researchers screened about 1,900 papers and kept nine. The mix included generally healthy adults and people with prior heart disease. Five studies totaling 455,619 people drove the mortality numbers: relative risk 0.61 for cardiovascular death (95 percent CI 0.48–0.79) and 0.76 for all-cause death (0.62–0.94). A sub-analysis highlighted about six flights a day — roughly 60 to 70 steps — as a range where the association looked particularly strong.

Vassiliou called stairs “a practical and often overlooked way to build physical activity into daily life.” Sophie Paddock, a co-author and cardiology registrar, said the pooled data showed a consistent link with lower cardiovascular and overall mortality. People who take stairs may also walk more, smoke less, or start healthier. The papers cannot separate those habits.

Climbing moves full body weight against gravity. Heart rate rises. Large leg muscles work. That is the same physiology behind “exercise snacking”: short bouts scattered through the day rather than one gym block. A 2019 McMaster and UBC Okanagan line of work found brief stair intervals several times a day can move fitness markers. Pooled snack-style trials have shown cardiorespiratory gains in the mid-single to mid-teens of percent. Walking volume has its own file: women under 2,000 steps a day showed higher heart-failure risk in JAMA Cardiology data compared with higher-step groups.

None of that makes an elevator ride a medical error. Stairs do not replace strength work, longer walks, or prescribed rehab. They add a repeated, unpaid load that many buildings already contain.

Observational designs cannot assign cause. Wearable measurement of actual flights is the next research step the team named. Stairs are not appropriate for everyone with severe joint disease or balance problems. Descending stairs is a different stimulus — eccentric loading with lower oxygen cost — and was not the main exposure in this review.

The useful claim is smaller than the headline. A cheap, daily climb is associated with lower cardiovascular death in a large pooled sample. Combining better sleep, more movement, and food quality has already been tied to fewer major heart events in other European preventive-cardiology work. Stairs are one of the movement pieces that do not require a membership.
