How to make your body clock work for you

How to make your body clock work for you


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.

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.
