Most of us take sunset as the cue to start winding down our day, but what if the sun never sets? The remote city of Inuvik, Canada is so deep in the Northern Hemisphere that it experiences months of non-stop sunlight in the summer, followed by months of fulltime darkness in the winter. Host Anahad O’Connor sits down with Inuvik resident Adi Scott who details what it’s like to keep a sleep schedule when you can no longer rely on the regular day-night cycle of the sun. Joined by neuroscientist and sleep expert Dr Steven Lockley, explore the powerful impact of light and dark on the brain, and how that triggers the complex internal mechanisms that influence our sleep.
