In Praise of Walking Summary

“Walking is not just what we do; it shapes who we are and fuels our brains, creativity, and social connections.”

1. Walking Differentiates Humans from Other Species

Walking upright on two legs is a fundamental aspect of what makes us human. This unique trait has evolutionary roots and plays a significant role in our physical and mental capabilities.

Walking as a biped separates humans even from their closest relatives, like apes, who primarily use all four limbs for movement. This evolutionary development gave us the ability to cover long distances efficiently and freed our hands for carrying tools, children, or food. In the early stages of human evolution, this was a key advantage in both survival and exploration.

Even though it feels effortless now, walking is a complex activity that requires coordination and brainpower. For example, toddlers learning how to walk stumble and fall countless times before mastering balance. Robots, despite technological advances, still struggle to mimic the intricate movements of human walking. Our brains, equipped with inertial guidance, play a constant role in balancing us, ensuring that our posture stays upright and our movement synchronized.

Walking is powered by more than just our brains; our spinal cords manage rhythmic patterns, controlling muscles for actions like walking or breathing. This intricate system separates humans from a stationary creature like the sea squirt, which eats its own brain and spinal cord once it stops moving. Walking, therefore, is not mere motion but a key human trait.

Examples

• Humans’ upright posture allows them to walk long distances, unlike most four-limbed animals.
• Toddlers require intensive practice, taking thousands of steps daily, to learn walking.
• Despite advancements, robots still have difficulty replicating the natural complexity of human walking.

2. Walking Requires a Built-In Direction System

Finding and navigating paths is an inherent capability of humans that extends beyond just visual recognition. Our inner sense of direction is a fascinating element of our walking ability.

Humans are equipped with an internal navigation system called dead reckoning or path integration. This system helps us orient ourselves in the right direction even without maps or external guides. For instance, before smartphones, individuals would confidently navigate through large cities like London without prior knowledge of the area, relying solely on this innate ability.

Scientific studies have revealed specific areas in the brain that govern our sense of direction. For example, place cells in the hippocampus light up as we move, indicating our current location. Head-direction cells work like an inner compass, guiding us to our desired orientation, while perimeter and boundary cells help us navigate spaces by responding to nearby objects and limits.

Blindness or lack of visual input only minimally affects this ability. Research on visually impaired individuals shows they can perform spatial navigation tasks just as effectively as those with sight. This proves that our sense of direction is deeply rooted in brain activity, not solely reliant on vision.

Examples

• Path integration enables people to navigate without visual maps, using innate cues.
• Place cells in the hippocampus are activated based on our spatial location.
• Studies show that blindfolded participants navigate spaces as well as sighted individuals.

3. Walkable Cities Drive Well-Being and Connection

Urban design has a profound influence on our walking habits and, subsequently, our mental and physical health. Cities should encourage walking, yet many fail to do so.

For a city to be considered walkable, daily amenities like stores and schools must be accessible on foot. Streets should feel comfortable and inviting, with ample green spaces like parks to offer refreshing environments. Think of iconic spaces like Hyde Park in London or Central Park in New York – these are havens for walkers.

Green and accessible spaces not only improve individual well-being but also boost the economy. Walkable cities tend to lead to increased local economic activity, as people shop and interact while on foot. Additionally, pedestrian-friendly design benefits the aging population, allowing seniors to stay mobile and independent longer.

Walkability isn’t just an aesthetic preference. It’s essential for fostering both individual well-being and community connections. Adopting urban planning principles like EASE – Easy, Accessible, Safe, and Enjoyable – could transform cities worldwide into healthier, more livable environments.

Examples

• Central Park serves as a natural escape for urban residents in New York.
• Neighborhood passeggiatas in Italy encourage social interactions.
• Older adults in walkable areas demonstrate higher mobility and independence.

4. Walking Influences Mood and Personality

Extended periods of physical inactivity correlate with negative changes in personality. But walking – the act of movement – can reverse these effects and brighten our mood.

Studies point out that people who rarely move around gradually become less agreeable, outgoing, and open to experiences. In contrast, walking elevates our mental well-being. Spending just an hour walking outdoors weekly can significantly decrease the likelihood of depression.

Research also shows that time spent in green spaces has a particularly uplifting effect. Walking in natural settings helps restore our mental state and reduces stress. For instance, a study that compared moods after riverside versus tunnel walks found that exposure to natural elements made people feel markedly better.

As low-effort as a walk may seem, it profoundly impacts our mental and physical state. After all, Hippocrates called walking the best medicine – and science continues to back that claim.

Examples

• People who walk an hour weekly show a 12% reduction in depression risk.
• Riverside walkers rate their moods far higher than tunnel walkers.
• Regular walks enhance openness and agreeableness in personality traits.

5. Walking Fuels Creativity

Walking has long been associated with generating creative ideas. When our legs move, our minds often enter a state that inspires original thinking.

Historical thinkers and creatives like Thoreau, Wordsworth, and Nietzsche often credited walking as essential to their intellectual work. Case in point: mathematician William Rowan Hamilton discovered a groundbreaking formula while walking in Dublin and immediately carved it onto a nearby bridge.

The secret lies in how our brains enter a specific mode while walking. Active thinking combines with a free-flowing default mode, which allows the brain to process memories and link ideas. This active idleness fosters the perfect mental state for innovation and problem-solving.

Walking outdoors further stimulates the memory- and navigation-related hippocampus, fine-tuning our ability to think creatively. For those struggling with challenging problems, a walk can often provide the breakthrough needed.

Examples

• Thoreau believed good ideas began with walking.
• Hamilton’s legendary formula discovery occurred during a stroll.
• Brain activity shifts between focus and wandering during walks, promoting insight.

6. Walking Connects Us to Others

While walking can be a solitary meditative process, it is also deeply social. Walking with others strengthens relationships and gives rise to shared experiences.

Simple activities like walking conversations foster meaningful connections. Even for children, the ability to walk marks a turning point in how they play and communicate. Elderly individuals who regularly walk display higher levels of sociability and well-being compared to their less active peers.

Walking in groups brings additional benefits, including synchronized steps and enhanced bonding. Activities like community marches or even protests produce collective psychological highs, demonstrating how walking fosters unity.

Even solo walks can have subconscious social components. Pilgrimages, for example, often connect walkers with a shared purpose or belief, even if they physically journey alone.

Examples

• Group walkers unconsciously synchronize their steps.
• Elderly individuals who walk socialize more actively.
• Pilgrims find spiritual connection despite walking alone.

Takeaways

1. Schedule daily walks to boost creativity and mental clarity; let your mind wander for breakthroughs in your projects.
2. Seek out green spaces like parks or riversides for recharging both mentally and physically during walks.
3. Advocate for and support urban plans prioritizing pedestrian-friendly designs to encourage walking in your community.
