Why Walking Is The Superpower You Didn’t Know You Had with Professor Shane O’Mara (Re-Release) #271

This conversation was first released in November 2019.   When was the last time you gave any real thought to walking? It’s so easy to put one foot in front of the other. Yet this unique, underrated activity sets us apart from other species, and brings incredible advantages – yes, superpowers – if we do it enough.   My guest on this week’s podcast is the neuroscientist Shane O’Mara, a professor of experimental brain research at Trinity College Dublin. After reading his remarkable new book, In Praise of Walking: The New Science of How We Walk And Why It’s Good For Us, I couldn’t wait to talk to him about the topics it raises. Shane has always been a keen walker and aims to clock 15,000 to 17,000 steps each day on his pedometer. But as we discuss, the positive effects of walking go way beyond the fitness benefits we all know about.   Walking helps more than our hearts and lungs, our muscles and posture, yet modern, sedentary lives mean we’re doing far less of it than nature intended. It can increase creativity and problem solving, lift our mood and protect us from depression. Shane reveals how it helps learning, memory and cognition and how it can slow and even reverse the functional ageing of the brain. All this science, he hopes, will help convince town planners and public health officials that we must redesign our environments with pedestrians in mind.   This is such an enlightening conversation and I know you’ll gain some fascinating new perspectives on how you could (and why you should) fit more walking into your life. Why not head out for a stroll as you listen? Thanks to our
Actionable Insights

1. Reverse Brain Aging with Walking

Engage in regular walking to improve memory, attention, increase hippocampal volume, and boost BDNF, which can functionally reverse brain aging and enhance cognitive functions throughout life.

2. Boost Creativity and Problem Solving

To enhance creativity and problem-solving, take a short walk (5-10 minutes) before intellectual tasks or when facing writer’s block, as this can double the generation of new ideas. For complex issues, outline key points before walking to facilitate rhythmic focusing and defocusing.

3. Lift Mood and Prevent Depression

Walk regularly to significantly lift your mood and reduce the risk of succumbing to major depressive disorder, as people consistently underestimate the positive emotional impact of physical movement.

4. Improve Sleep and Mental Health

Prioritize both ample walking and quality sleep, as these two actions are paramount for mental and physical health, with consistent daily movement directly contributing to better sleep.

5. Aim for High Daily Step Count

Strive for a daily step count of 15,000-17,000 steps, or at least 10,000 steps, as this high level of consistent movement is achievable and provides significant health benefits.

6. Choose Movement Over Convenience

Actively choose movement by taking stairs instead of escalators or lifts, walking short distances instead of driving, and generally avoiding outsourcing physical activity to machines to counteract sedentary defaults.

7. Reduce Inflammation Through Walking

Engage in prolonged periods of walking, especially in nature over several weeks, to dramatically reduce inflammatory factors in the blood, which can combat chronic inflammation.

8. Integrate Walking into Daily Routines

Implement small, consistent changes like keeping comfortable shoes handy, taking walking breaks every 25 minutes, parking further away, or exiting public transport early to effortlessly increase daily steps. Consider joining a walking group for social motivation.

9. Prioritize Minimally Processed Foods

Shift towards a diet of minimally processed, high-fiber foods, such as eating whole fruits instead of smoothies, to make your body work harder to extract calories and avoid the negative health impacts of highly processed foods.

10. Avoid Post-Exercise Inactivity

Be aware of ’exercise-induced inactivity’ and the ‘psychological license’ to overeat after intense workouts; instead, focus on consistent, distributed movement throughout the day rather than relying solely on short, intense gym sessions.

11. Track Steps for Motivation

Use a pedometer or smartphone to passively track your daily steps, as this data can serve as a positive motivator to meet personal step goals and increase overall daily movement.

12. Walk Mindfully or with Distraction

If your goal is simply to get moving, listen to podcasts or music while walking. However, if you’re aiming for problem-solving or deep reflection, walk without auditory distractions to foster focused thought.
