How to feel alive in an exhausting world

In this episode of the TED Radio Hour, host Manoush Zomorodi explores the growing epidemic of exhaustion in modern life, driven by sedentary behavior, screen overuse, and disrupted biological rhythms. Drawing from NPR's Body Electric Study involving over 20,000 participants, she reveals that simple, frequent movement breaks—just five minutes every 30 minutes—can dramatically improve glucose levels, blood pressure, mood, and energy. The episode then delves into the science of mitochondria, the cellular powerhouses that regulate energy flow, with researcher Martin Picard explaining how mitochondrial health is central to both physical and mental well-being. He introduces the emerging field of mitochondrial psychobiology, showing how energy flow and cellular communication underlie the mind-body connection. Finally, science journalist James Nestor discusses the overlooked importance of nasal breathing, demonstrating through personal experiments and research that poor breathing habits contribute to chronic illness, while proper nasal breathing enhances oxygenation, focus, and emotional regulation. Together, these insights offer practical, science-backed antidotes to modern fatigue: movement, mitochondrial support, and mindful breathing.
