When the Sun Doesn’t Sleep

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 far north that it experiences non-stop sunlight in the summer, followed by round-the-clock darkness in the winter. Inuvik resident Adi Scott details what it was like to move to this unique part of the planet, and the unique ways she keeps a sleep schedule when it isn’t possible to rely on the regular day-night cycle of the sun. Joined by neuroscientist and sleep specialist Dr Steven Lockley, learn about the powerful impact of light and dark on the brain, and how that triggers the complex internal mechanisms influencing our sleep.
