What time should you go to bed? Are you sleeping enough? Is Daylight Savings good for us? Is shift work really that bad? How dark is dark enough? Katherine Hatcher, who studies hormones, sleep cycles and circadian rhythms, helps Alie dissect her terrible sleep habits and talks about a magic tiny area in our brains that acts as your body's Big Ben. By the end of the episode, you'll be in footie pajamas eager to change your whole life.
