What sitting all day does to your brain and body | Keith Diaz | Your Body on Tech

This is episode one of a seven-part series airing this week on TED Talks Daily, where author and podcaster Manoush Zomorodi — and the seven speakers she curated for TED2026 — explore how you can live a healthier life in our high-tech era.


Can a five-minute walk change how you feel all day? Exercise scientist Keith Diaz shows how your body is built for the kind of movement that modern life has quietly erased — and suggests something refreshingly doable: making time for small doses of movement sprinkled throughout the day, as a way to boost your brain and body. And stick around after his talk for a deep dive conversation with Manoush into the ideas he shared on stage and beyond.


To hear more from Manoush, listen to TED Radio Hour wherever you get your podcasts. Check out her new book, Body Electric, to learn more about the hidden health costs of the digital age.
