Summary

In today’s world, we increasingly live our lives late into the night. Whether it's work obligations, socializing, or being glued to a screen, we ignore the sun's rise and fall. But most of us are unaware that a clock is ticking away inside us. It uses light to keep time and tells us when to sleep and eat. Should we listen? Or is this biological clock simply a relic from a past time? In today’s episode, Jonathan speaks to a leading authority to unravel the latest science that reveals that this body clock, or circadian rhythm, has a dramatic impact on our health, weight, and mental wellbeing: Russell Foster is an Oxford University scientist who has dedicated his life to studying circadian rhythms. He’s a world leader in the field and the author of Lifetime: the new science of the body clock.
