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

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 our guest host for the week, author and podcaster Manoush Zomorodi, into the ideas he shared on stage and beyond.

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