Why Walking Is The Superpower You Didn’t Know You Had with Professor Shane O’Mara #84

Nov 20, 2019 1h 33m 23 insights
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?

Actionable Insights

1. Prioritize Sleep & Walking

Prioritize getting lots of proper quality sleep and engaging in ample walking, as these are the two most important things you can do for both your mental and physical health.

2. Walk for Brain Anti-Aging

Engage in regular walking, even just three times a week for about a mile and a half, to improve memory and attention, increase hippocampal volume, boost BDNF, and functionally reverse brain aging.

3. Walk to Boost Mood

Go for a walk for at least 20 minutes to reliably elevate your mood, as people consistently underestimate the significant positive emotional impact of walking.

4. Walk to Prevent Depression

Increase your daily walking activity to significantly reduce your risk of developing major depressive disorder, as the risk falls with every level of walking above sedentary.

5. Integrate Movement Throughout Day

Distribute physical activity throughout your entire day, rather than concentrating it into a single intense session, as humans are designed to move about more or less every hour for better health outcomes.

6. Prioritize Minimally Processed Foods

Shift your diet away from highly processed foods towards minimally processed options, as these require your body to work harder to extract calories and lead to better health outcomes.

7. Walk for Creativity & Problem-Solving

Before engaging in intellectual or creative tasks, take a short walk (5-10 minutes) to generate on average twice as many new ideas and enhance problem-solving capabilities.

8. Aim for 15,000-17,000 Daily Steps

Aim to walk 15,000 to 17,000 steps every day, as this is a level the neuroscientist guest believes everyone should be doing for broad benefits beyond just fitness.

9. Use Active Idle Thought

When facing a problem or writer’s block, go for a walk to engage in an ‘active idle mode of thought,’ allowing your brain to rhythmically focus and defocus on the problem, which can lead to solutions.

10. Walk Without Auditory Distraction

When trying to solve a difficult problem or engage in deep self-reflection during a walk, avoid auditory distractions like podcasts or music to allow for clearer thought processes.

11. Track Daily Steps

Use a pedometer or smartphone app to track your daily steps, as this helps you become more conscious of your activity levels and how they correlate with your well-being, given that humans are not good at remembering this data otherwise.

12. Keep Comfortable Shoes Handy

Always keep a comfortable pair of walking shoes readily accessible (e.g., under your desk at work) to facilitate spontaneous walks during breaks or lunchtime.

13. Set Movement Alarms

If working at a computer, set an alarm to go off every 25 minutes to prompt you to get up and walk around, effectively breaking up sedentary periods.

14. Park Further Away

When driving to a destination, intentionally park further away than necessary to incorporate extra walking into your daily routine.

15. Get Off Public Transport Early

If using public transport, get off a few stops earlier than your final destination and walk the remaining distance to easily increase your daily steps.

16. Choose Distant Lunch Spots

When getting lunch, choose a slightly more distant shop or restaurant to accumulate an extra 800-1200 steps during your break without much thought.

17. Walk Kids to School

Make a family vow to walk children to school daily, even if it’s a 25-minute journey, to integrate more movement into daily routines and set a positive example.

18. Eat Whole Fruit, Not Smoothies

Choose to eat whole fruits instead of drinking smoothies, as eating whole fruit requires your body to work harder to extract calories, which is better for your health.

19. Prioritize Movement Over Convenience

Make a conscious rule to avoid outsourcing physical activity to machines or electronic appliances whenever possible, choosing stairs over escalators or walking instead of driving short distances.

20. Walk for Anti-Inflammatory Effects

Engage in prolonged periods of walking, such as several weeks in nature, to significantly reduce inflammatory factors in the blood, which can contribute to overall health and potentially mitigate inflammation-related conditions.

21. Advocate for Walkable Environments

Advocate for urban planning that prioritizes pedestrians by making cities and towns ’easy’ (accessible, safe, enjoyable) for walking, viewing streets as destinations rather than just thoroughfares.

22. Join Podcast Community Meetups

Join the Dr Chatterjee Four Pillar Community Tribe on Facebook to connect with other listeners, discuss podcasts, and potentially arrange or start local in-person meetups to share insights and inspire better choices.

23. Wear Minimalist Walking Shoes

Consider wearing minimalist shoes, like Vivo Barefoot, for walking to help transition to minimalist footwear and better connect with your feet and the ground.
