Instant Genius is a bite-sized masterclass in podcast form. And in this episode, we're exploring your body clock.

And for good reason. Your body clock, or circadian rhythm, doesn’t just influence your energy levels throughout the day. Recent studies have revealed that your internal timekeeper also has a significant impact on your bodyweight, immune system, mental health, sleep quality and more.

How can this be possible? And what are the simple things you can do to live more in sync with your biological timepiece? To answer these questions and more, we’re joined by Russell Foster, professor of circadian neuroscience at the University of Oxford and author of Life Time: The New Science Of The Body Clock, And How It Can Revolutionize Your Sleep And Health.
