Walking Up Stairs and Its Benefits for Your Health
Every day we walk past them. We stand before them, hesitate, and then look around for the elevator. Stairs – such an ordinary part of everyday life, and yet one of the most underestimated tools for taking care of our own health. While most people search for complex exercise plans, expensive gym memberships, or special dietary supplements, the answer to many health problems may literally lie at our feet.
Research from recent years is increasingly and convincingly showing that regular stair climbing is one of the most effective forms of movement that a modern person can incorporate into their day. No equipment is needed, no trainer, no special clothing. All it takes is the decision to move from the elevator to the staircase.

Why stairs are more than just a way from one floor to another
When someone climbs stairs, their body is doing far more than it might appear at first glance. It is a movement that engages large muscle groups – the thigh muscles, calves, glutes, and core. Unlike walking on flat ground, the body must overcome gravity, which significantly increases energy expenditure. According to data published in the peer-reviewed journal British Journal of Sports Medicine, just ten minutes of stair climbing per day can reduce the risk of cardiovascular disease by several percentage points – even in people who otherwise do not exercise.
The heart works more intensively when climbing stairs than during ordinary walking. Heart rate rises, blood vessels dilate, and blood circulates more effectively. Regular repetition of this process gradually strengthens the heart muscle, improves vascular elasticity, and contributes to lowering blood pressure. This is not a dramatic athletic feat – it is a natural movement that the human body can manage even in middle age and without prior fitness.
An interesting perspective is offered by a 2021 study published in Medicine & Science in Sports & Exercise, which followed a group of adults aged 40 to 65 over six months. Participants who climbed at least four flights of stairs every day showed measurable improvements in cardiovascular health indicators – lower LDL cholesterol levels, better blood pressure values, and higher aerobic capacity. And this involved no organised training whatsoever, merely a deliberate change to one everyday habit.
Imagine Petr, a forty-four-year-old sales manager from Brno who spends most of his day at a computer. On his doctor's recommendation, he started taking the stairs instead of the elevator in his apartment block – four flights up and down every morning and every evening. After three months, his doctor measured lower blood pressure at a routine check-up, and Petr himself reported feeling less out of breath during physical exertion. No gym, no diet – just stairs.
Benefits for joints: myth or reality?
This is where many people hesitate. There is a widespread belief that stair climbing puts strain on the joints and wears them out. The truth, however, is more nuanced – and more favourable to stairs – than it might seem. Joints need movement to stay healthy. The cartilage that protects joints has no blood supply of its own – it receives nutrients precisely through movement, which draws synovial fluid into the joint. Without regular movement, cartilage gradually degenerates.
Stair climbing at a moderate intensity and with proper technique does not place excessive strain on the joints – on the contrary, it strengthens them by reinforcing the surrounding musculature that stabilises and protects the joint. The key word here is "moderate." Different rules apply to someone with advanced arthritis or following knee surgery than to a healthy individual. The World Health Organization, in its recommendations for physical activity in adults, emphasises that physical activity should be adapted to one's current state of health, while also noting that physical inactivity is one of the greatest global health risks.
For healthy knees and hips, stair climbing has another less frequently mentioned benefit: it improves proprioception – the body's ability to sense the position and movement of its own joints in space. This ability naturally declines with age, and its deterioration is one of the main causes of falls in older people. Regular stair climbing maintains and develops it, resulting in better balance and coordination.
As orthopaedic surgeon and sports physician MUDr. Ondřej Naňka once said in an interview for a specialist portal: "Movement is to joints what lubricant is to a machine. Moderate load does not destroy joints – on the contrary, it keeps them functional far longer than inactivity does."
How many stairs per day is actually enough?
This is the question that concerns everyone who wants to get the most out of stair climbing without unnecessary overexertion. The answer depends on age, current fitness level, and health status, but there are general guidelines that make sense for the majority of the population.
Research consistently suggests that climbing approximately four to six flights of stairs per day delivers measurable cardiovascular benefits. This corresponds to roughly 60 to 80 stair steps going up. For someone who lives on the third floor of an apartment building, this is precisely how many steps they take on every journey home. For others, it might mean a conscious decision to go two floors higher than they actually need to be, and then walk back down.
Interestingly, the descent matters too when it comes to health benefits. Walking down stairs engages the muscles differently – they work eccentrically, meaning they brake the movement, which has a positive effect on muscle strength and bone tissue metabolism. Descending stairs is gentler on the cardiovascular system but more demanding on the joints, so it is advisable to be more cautious and choose a slower pace.
For those who want to start, a simple principle of gradual progression applies. There is no need to immediately conquer high-rise buildings. It is enough to begin with one or two extra flights per day and gradually increase the pace and distance. The body adapts surprisingly quickly – fitness improves, muscles grow stronger, and what initially felt strenuous becomes routine after a few weeks.
There are also several practical ways to naturally incorporate stairs into everyday life without the need for special planning:
- Get off the metro or bus one stop earlier and walk the rest of the way to your destination on foot, using stairs where available
- At work, use the stairs instead of the elevator for moving between one or two floors at least
- When shopping at a shopping centre, deliberately skip the escalator and choose the staircase
- At home, repeat the climbs consciously – for example, every time you leave and return to your flat
Such small decisions accumulate. Research published in Preventive Medicine showed that people who consistently choose stairs over the elevator have on average a 0.15 lower BMI and display better metabolic health indicators than their peers with a sedentary lifestyle – even though they do not exercise more in any other way.
What happens in the body with regular stair climbing
A look at the physiology of stair climbing reveals why this seemingly unassuming movement is so effective. In terms of intensity, stair climbing falls into the category of moderate-intensity aerobic activity – precisely the range that the World Health Organization recommends as the foundation of a physical activity programme for adults. The heart works at 60 to 75 percent of maximum heart rate, which is the ideal zone for strengthening the cardiovascular system.
Regular aerobic exertion in this range stimulates the formation of new capillaries in the heart muscle and in skeletal muscle, improves the ability of cells to process oxygen, and supports healthy fat metabolism. At the same time, endorphins – the feel-good hormones – are released, which explains why many regular stair climbers report improved psychological wellbeing and lower levels of stress.
From the perspective of bone density, stair climbing is particularly valuable for women after menopause and older men, in whom the production of hormones that protect bones from thinning naturally declines. The mechanical load on the bones that stairs provide stimulates osteoblasts – the cells responsible for forming new bone tissue – and slows the natural decline in bone density. It is a natural and cost-free form of osteoporosis prevention.
It is worth noting that the caloric expenditure of stair climbing is approximately two to three times higher than walking on flat ground at the same speed. For a person weighing 70 kilograms, climbing four flights of stairs burns approximately 5 to 8 kilocalories – seemingly little at first glance, but adding up to thousands of kilocalories over the course of a year. And all without changing anything else in one's lifestyle.
Stairs are, in a sense, a democratic form of exercise. They are accessible to nearly everyone, require no investment, take no extra time, and deliver benefits that science is confirming with ever greater conviction. At a time when a healthy lifestyle can sometimes seem to be a matter of expensive products and complicated programmes, stairs serve as a reminder of a simple truth: the best movement is the one we actually do – every day, repeatedly, and without excuses. And next time you find yourself choosing between the elevator and the staircase, making the right decision may just be a little easier.
