Stair climbing imposes a simple mechanical demand: repeated concentric work against gravity, engaging multiple muscle groups and elevating cardiac output without requiring dedicated equipment or structured sessions. That accessibility is part of why researchers at the University of East Anglia and Norfolk and Norwich University Hospital put it at the center of a cardiovascular mortality analysis. Their findings, published in the American Journal of Cardiovascular Drugs and drawing on data from more than 480,000 people, show that stair climbers had a 39% lower risk of dying from cardiovascular disease and a 24% lower risk of all-cause mortality compared with non-climbers.
What the data cover
The research team, including Vassilios Vassiliou and Sophie Paddock from UEA's Norwich Medical School, started from a pool of nearly 1,900 studies before narrowing to nine with usable outcome data. Participants ranged from 35 to 84 years old and included both healthy individuals and people with prior cardiac histories, with a median follow-up of 14 years. Beyond mortality, stair climbers were also less likely to develop heart attack, stroke, and heart failure.
One large study in the analysis pointed to roughly six flights per day as the level associated with the greatest benefit, though the researchers said more work is needed to pin down the optimal dose. Paddock said the review showed a gradient: more stairs, greater benefit. She also noted that even small changes produced measurable differences and that brief bouts of stair climbing should be achievable to integrate into daily routines.
The compliance gap
The study sits against a specific backdrop. Vassiliou described cardiovascular disease as the leading cause of death globally, with cases nearly doubling between 1990 and 2019. More than a quarter of adults worldwide currently fall short of recommended activity levels, the researchers noted. Sedentary behavior, smoking, poor diet, and obesity all contribute to the disease burden. The argument for stair climbing rests on where it sits relative to that gap: cost-free, available at home, at work, and in public spaces, and compatible with existing daily movement rather than requiring a separate block of time.
The researchers were explicit that the analysis establishes association, not causation, and flagged that stair climbing may be inappropriate for people with mobility limitations or joint conditions.
