Our understanding of the body's internal clocks is rapidly evolving, with new research shedding light on the powerful effects of circadian rhythms. From the way artificial light disrupts our sleep patterns to how animals’ natural cycles offer valuable insights into human health, the science is undeniable. 

Dr. Philippa Gander, a leading expert in sleep and circadian rhythms and author of Life in Sync: The Science of Internal Clocks and How We’re Disrupting Them explains how these disruptions impact not just humans but entire ecosystems, including marine life. 

Her groundbreaking work also reveals the profound effects of light pollution, offering fresh perspectives on how we can better align our lives with our biological clocks. In this conversation with Peter Bowes, Gander also highlights practical ways we can make adjustments to better sync our lives with nature’s rhythms for improved health and well-being.
