How does a 10-minute walk improve focus and attention?
A single 10-minute walk produces an immediate improvement in focus by activating the prefrontal cortex and triggering the formation of new synapses. According to Dr. Wendy Suzuki, neuroscientist and Dean of the College of Arts and Science at New York University, improved focus is the most consistently reported positive effect from scientific studies on exercise and the brain. With regular exercise over time, baseline levels of focus and attention rise — and those gains reflect real, measurable physical changes in the brain itself.
The mechanism is neurochemical. Every time you move your body, even for just a short walk, your brain releases a flood of compounds — dopamine, serotonin, noradrenaline, endorphins, and growth factors. These neurochemicals get to work immediately, which is why the focus benefit shows up so quickly, without needing to run a marathon or even break a real sweat. The threshold is low enough that anyone can cross it.
"Every single time you move your body, you are releasing literally a flood of neurochemicals in your brain. I'm not talking about run a marathon. I'm talking about even taking a walk, a 10-minute walk gets that flood of neurochemicals going."
— Wendy Suzuki, neuroscientist, New York UniversitySuzuki shared these findings as part of a broader episode of The Mel Robbins Podcast dedicated to five science-backed tools for shifting your mood fast — each drawn from expert conversations Mel Robbins has hosted. The walking insight is one of those tools, and its simplicity is part of the point: you don't need a gym, a plan, or a lot of time. Ten minutes is enough to start changing how your brain works.
About Wendy Suzuki
Dr. Wendy Suzuki is a world-renowned neuroscientist and the Dean of the College of Arts and Science at New York University — one of the most prominent research universities in the United States. Her scientific work centers on memory, brain plasticity, and the practical, everyday behaviors that can improve cognitive performance. What sets Suzuki apart from many researchers is her focus on accessible interventions: not clinical treatments or elite athletic programs, but simple daily habits — like a 10-minute walk — that anyone can apply. She is also at the forefront of emerging research on how physical movement directly shapes brain health, examining the neurochemical cascades that exercise triggers and how repeated activity leads to lasting structural changes in the brain. Her authority on the question of focus and walking is grounded not in anecdote, but in years of laboratory research on how the brain adapts to physical activity at a cellular level.
