Throughout history, few things have inspired as much fascination as the quest for longevity and vitality. Amid the plethora of pills, potions, and promises, some enduring truths remain. Hippocrates, often regarded as the father of modern medicine, famously proclaimed in 400 BC that “Walking is man’s best medicine.” This wisdom resonates strongly today, with a growing body of scientific research reaffirming the health benefits of walking, particularly in light of the recent assertion that walking more than 8,000 steps daily can halve the risk of premature death compared to walking fewer than 5,000 steps—the threshold that marks a sedentary lifestyle. While this highlights a significant health advantage, it also raises questions about the long-touted benchmark of 10,000 steps a day, a figure rooted more in marketing than scientific evidence.

Originating from a 1960s Japanese advertising campaign for the first commercial pedometer, the manpo-kei, the 10,000-step goal has long entrenched itself in popular culture. More recent studies suggest that stepping beyond this number may not yield notably increased health benefits. For example, research indicates that simply increasing the intensity of walks—achieving a brisk pace of more than 100 steps per minute—can produce substantial health improvements. Evidence shows that trading a leisurely 14-minute stroll for a brisk walk can reduce heart disease risk by 14%, as also noted in analysis involving over 450,000 adults in the UK, highlighting that brisk walking can effectively reduce biological age by up to 16 years compared to slower walking.

Interestingly, the benefits of brisk walking extend beyond mere physical health. A recent study indicated that the speed of one’s walking pace might be a more telling indicator of future health outcomes than traditional metrics like blood pressure or cholesterol levels. Furthermore, assessing a patient’s walking pace relative to others could potentially provide invaluable insight into their cardiovascular health. Yet, brisk walking is not always superior; notably, when it comes to mitigating cancer risk, the benefits of light-intensity walking or even simply breaking prolonged sitting periods can be profound strategies.

In addition to the physical benefits, walking offers a plethora of mental health advantages. Engaging in walking—especially through natural environments—can stimulate brain activity, doubling creative idea production and enhancing cognitive functions. Some studies suggest that walking in nature can amplify these mental health benefits, leading to improved mood and resilience against stress. Such insights have led to initiatives incorporating “nature prescriptions,” especially for clinical populations, aiming to boost physical activity and improve overall health.

The focus on walking arises amid a broader conversation about public health strategies in the face of rising physical inactivity, which contributes significantly to the prevalence of chronic conditions such as diabetes and heart disease. It is estimated that 3.9 million premature deaths could be prevented annually by addressing physical inactivity. A realignment of health spending to prioritise initiatives that promote walking could lessen the burden on healthcare systems, which currently rely heavily on treating illnesses rather than preventing them through simple lifestyle changes.

Ultimately, as we seek effective pathways to improved well-being, the evidence suggests that there is wisdom in Hippocrates’s ancient assertion. Embracing the simple act of walking—whether striving for 8,000 steps or aiming for brisk outings—could be one of the most accessible and beneficial choices available for enhancing our health and longevity.
