#106: Multitasking Myths, Focus & Real-World Brain Health - Therese Huston, PhD

Cognitive scientist Dr. Therese Huston joins The FitMind Podcast to share practical, research-backed ways to sharpen focus, lower stress, and keep the brain healthy at any age. Drawing from decades of neuroscience, she explains why multitasking quietly erodes attention and memory and what to do instead. We explore simple, realistic habits that help your mind function at its best: 20-minute single-task blocks, 40 Hz binaural beats for deep focus, and a brief 5-2-7 breathing technique that can quickly calm the nervous system. Dr. Huston also highlights how aerobic movement, dance, and social connection drive neurogenesis and long-term brain vitality. If you’ve ever felt scattered, stressed, or mentally drained, this episode offers grounded science and clear tools for regaining clarity and calm in daily life.
