#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.   FitMind Neuroscience-Based App: http://bit.ly/afitmind Website: www.fitmind.org SHOW NOTES 00:00 | Intro to Dr. Therese Huston 07:45 | Wellness overwhelm and how she filters research into usable habits 10:06 | Why "practical" matters more than trendy protocols 12:20 | The multitasking myth: short-term mood boost, long-term costs 17:09 | Live demo: single-tasking vs alternating tasks 19:40 | Errors, brain activity, and stress during multitasking 21:51 | Escaping the multitasking loop with timers and clear agreements 24:30 | Focus tools: how to use 40 Hz binaural beats 28:47 | Why multitasking feels productive and how to reframe arousal 32:33 | Before a talk: "excited, not anxious" and stress-as-fuel 36:03 | Guided 5-2-7 breathing and what it does in the body 41:18 | CO₂, vagus nerve, and decision quality after breath cycles 43:19 | Rethinking "amygdala hijack" and protecting prefrontal control 48:18 | BDNF, neurogenesis, and an aerobic exercise target for memory 51:24 | Dance, social connection, and brain longevity 52:53 | Quick fire: myths to ditch and personal focus resets 54:45 | Exercise snacks and team culture ideas
