There’s more to sleep than being a good sleeper. So many factors—from overall health to our environments—impact our experience of sleep and how our brains and bodies behave while sleeping. From restless leg syndrome to sleepwalking to narcolepsy, researching and diagnosing sleep uncovers myriad solutions for getting the quality sleep that helps us live our best lives. In this episode, Anahad speaks with doctors whose passion and calling is sleep in all forms. Dr. Logan Schneider, a clinical assistant sleep professor of Sleep Medicine at the Stanford Sleep Center, the important role sleep analysis plays in managing our health. Sleep neurologist Dr. Chris Winter returns to the show to share his insights on the importance of evaluating our sleep and the future of sleep wellness and health.

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.

Astronauts undergo rigorous training to prepare their bodies and minds for space, but once they arrive, the experience of being weightless thousands of miles above Earth is like nothing they’ve ever felt before.

Sleep science researcher Dr. Mathias Basner joins to share how zero gravity and noise can impact everyday activities like resting in space.

When you’re a wildlife documentarian, you camp in the most remote parts of the world, ready at a moment’s notice to record elusive subjects. You also have to sleep when you can, where you can, often in extreme, uncomfortable, sometimes sub-zero conditions.
