Episode notes

Rituals helps you to slow down, take the time to relax, and find a moment of peace in your busy day.

This episode is dedicated to the body clock. How do we know when to go to sleep? Why are some people morning people and other people night owls? It’s all determined by our body clock – something scientists call the circadian rhythm; the system that determines our wakefulness. This internal system plays a crucial role in how we feel and performs all sorts of important functions in our body and brain.

Dr. Russell Foster is a professor and Head of the Sleep and Circadian Neuroscience Institute at Oxford University. He explains that even though our circadian rhythms are all slightly different, they’re all synchronised by one thing: daylight. Without this, our clocks would go wild and we’d eventually end up sleeping in the daytime and being wide awake at night.

Linda Geddes is an author and award-winning journalist. She has written the book ‘Chasing the Sun’ about how sunlight shapes our bodies and minds. She shares her experiences about an experiment she did, trying to change her body clock with daylight.
