Climbing 5 Flights of Stairs Daily Cuts Heart Disease Risk

Every day, you make a choice without thinking about it: elevator or stairs. You probably tap the elevator button — like the overwhelming majority of Americans do in office buildings, malls, and apartment towers. But according to a growing stack of research, the staircase you've been ignoring might be the single most underrated exercise machine in your life. One big study suggests that climbing at least five flights of stairs a day is associated with roughly a 20% lower risk of cardiovascular disease.

No gym membership. No workout clothes. No scheduled time. Just stairs.

What the science says

In 2023, researchers at Tulane University published a study in the journal Atherosclerosis that analyzed more than 458,000 adults in the UK Biobank. People who climbed at least five flights of stairs a day — compared with people who never climbed stairs — had about a 20% lower risk of atherosclerotic cardiovascular disease, the umbrella term for heart attack, stroke, and related conditions.

The effect held even after adjusting for factors like diet, smoking, age, and other exercise. In other words, the stair climbers weren't just healthier in every way — the stair climbing itself appeared to carry the benefit.

That was one study. Then came the meta-analysis. In 2024, the same Tulane team pooled data from nine studies covering nearly 481,000 participants. Habitual stair climbers had roughly a 24% lower risk of dying from any cause and about a 39% lower risk of dying from cardiovascular disease than non-climbers.

"Short bursts of high-intensity stair climbing are a time-efficient way to improve cardiorespiratory fitness and lipid profiles," the researchers concluded — and the benefits scaled with the dose. The more stairs climbed, the lower the risk, at least up to a point.

Why stairs beat flat walking

Walking is wonderful — but stair climbing is a different animal. Climbing stairs burns roughly 8 to 11 times your resting metabolic rate, putting it squarely in the vigorous-intensity category. For comparison, brisk walking on flat ground sits at about 3 to 4 times resting. Minute for minute, stairs can burn two to three times more calories than walking.

There's a muscle story too. Each step up is essentially a one-legged squat: your quads, glutes, hamstrings, and calves fire in sequence, and your bones get a healthy dose of load-bearing impact. That matters because leg strength — and grip strength, covered in our earlier reporting — tracks closely with longevity. After age 30, Americans lose 3 to 8% of muscle mass per decade, and stair climbing is one of the simplest resistance workouts available: it's literally in your building.

And then there's blood sugar. A small but influential body of research has found that brief bouts of stair climbing and descending after meals blunt post-meal blood sugar spikes — a key driver of insulin resistance and type 2 diabetes, which now affects roughly 1 in 10 American adults.

The catch: intensity is the point

Here's the honest part: shuffling up one flight once a day probably won't move the needle much. The dose matters. The big studies pointed to a threshold around five flights a day — that's roughly 50 to 100 steps, depending on the building. Taken at a purposeful pace, that's about five to ten minutes of total activity, spread however you like across the day.

Interestingly, the meta-analysis found the protective pattern was strongest for people who would otherwise be sedentary. If you already run marathons, stairs are dessert, not the meal. But if your daily routine involves an office chair, a car, and a couch, swapping the elevator for the stairs may be the highest-return health decision you can make in under ten minutes.

How to start: the stair-first plan

1. Audit your building. Count the floors you currently take the elevator for. Two flights? Start there. You need five total across the day — morning, lunch, and evening trips add up fast.

2. Build in one week. Add one flight per day until you hit five. If you can already do five easily, take them two steps at a time for extra leg work — that's closer to a sprint interval.

3. Use the handrail. Falls on stairs injure hundreds of thousands of Americans a year. Hold the rail, wear shoes with grip, and take wet or outdoor stairs slowly.

4. Treat it as exercise, not a chore. A brisk pace matters — you should feel your heart rate rise and your legs warm up. If you can chat comfortably the whole way, speed up.

5. Mind your knees. People with significant knee arthritis should start flat and short, and talk to a doctor or physical therapist before loading up flights. Going down is harder on knees than going up — take descents at a controlled pace or use the elevator down if needed.

6. Pair it with what you already do. Take the stairs before lunch and after your last bathroom break. Anchoring the habit to something existing is the most reliable way to keep it.

The bottom line

Health experts have a phrase for this kind of thing: "exercise snacking" — short bouts of vigorous movement scattered through the day. Stair climbing is the original exercise snack, available in nearly every American office, mall, airport, and apartment building, free of charge.

The elevator will still be there when you're carrying groceries or nursing a sore ankle. But on ordinary days, the staircase is offering you something the elevator can't: a stronger heart, better blood sugar, and legs that will carry you further, for longer. Five flights a day. That's the deal.
