The 10,000-step myth: Does it really hold the key to better health? It's a question many fitness enthusiasts ponder. The idea of walking 10,000 steps a day has become a fitness mantra, promoted by smartwatches and walking groups alike. But is there more to the story? Let's dive in.
The concept originated in 1960s Japan, where a company marketed a pedometer called “manpo-keī,” which translates to “10,000 steps meter.” It was catchy, memorable, and quickly became a public health goal. But here's where it gets controversial: there's surprisingly little scientific evidence to back up that specific number.
However, the benefits of walking are undeniable. Numerous studies have linked increased daily steps to a reduced risk of cardiovascular diseases. One large review found that adding just 1,000 steps a day could lower the risk of death by 12%.
Walking may be even more beneficial for those with diabetes. One trial showed that overweight women who walked 10,000 steps daily improved their glucose tolerance and lowered their blood pressure, even without losing weight.
And this is the part most people miss: In a Nigerian study, patients with type 2 diabetes who followed a 10,000-step prescription saw improvements in their HbA1c levels, a key indicator of blood sugar control, even though most didn't reach the full target.
But let's look at the bigger picture.
A Growing Diabetes Crisis
According to a 2024 meta-analysis, the prevalence of type 2 diabetes mellitus (T2DM) in Nigeria is around 7%, affecting over 8 million adults. This is a significant increase from previous estimates, with projections indicating that 1 in every 30 Nigerians will have diabetes by 2030. This is among the highest rates in Africa.

Walking as a Simple Solution
Walking is a readily accessible form of exercise that requires no gym membership. Physiotherapist Chinazaekpere Amadi explains that walking acts as a natural physiological regulator, improving insulin sensitivity and cardiovascular health. She emphasizes that it's not about the number of steps, but the intensity of the walk.
Studies support this view. A Harvard Health report found that adults who walked about 7,000 steps per day had a 25% lower risk of cardiovascular disease and a 47% lower risk of dying from any cause compared to those who walked only 2,000 steps.
But here's a reality check: For many Nigerians, even reaching 7,000 steps can be a challenge. The lack of pedestrian-friendly infrastructure and safety concerns discourage outdoor walking. In cities like Lagos and Port Harcourt, broken sidewalks and heavy traffic make walking less appealing.
Cultural habits also play a role. Car-dependent commutes, long work hours, domestic help, and a preference for convenience mean many adults don't move much beyond essential activities.
Amadi often prescribes walking to her patients, suggesting they start with 5 minutes a day, 5 times a week, gradually increasing the duration and intensity. Consistency is key. Starting small builds confidence, helps muscles adapt, and reduces the risk of injury, especially for those with diabetes who may experience neuropathy or balance issues.
No One-Size-Fits-All Approach
Timothy Aniju, a physiotherapist at the University of Benin Teaching Hospital, stresses that walking should be individualized. Exercise routines should be customized based on the FITT principle: Frequency, Intensity, Time, and Type of exercise.

Nigeria's public health system could do more to make walking practical. Urban planners could prioritize pedestrian-friendly infrastructure, local councils could build community walking trails, and employers could integrate movement breaks into work schedules.
While the 10,000-step target may be a myth, the simple act of walking can still work wonders.
