In Why Walking Matters, Marcus Reed Halloway reveals the surprising science behind the simplest human activity—walking—and its profound impact on your brain. Backed by research from Harvard Health, the Mayo Clinic, and the NIH, this book shows how a regular walking practice can sharpen your memory, boost creativity, reduce anxiety, and even stave off age-related cognitive decline. You don't need expensive equipment or hours of gym time; just your own two feet and a willingness to step outside. Halloway, a health communicator, translates complex neuroscience into actionable advice: how to set your pace, choose your route, and integrate walking seamlessly into your daily life. From the feel-good chemistry of endorphins to the regenerative power of BDNF (brain-derived neurotrophic factor), every chapter builds a compelling case for making walking your primary brain health tool. Whether you're a seasoned walker or a complete beginner, this guide will change how you think about movement and mind. Part of The Sagewell Wellness Library.
