This episode of the New Tech City podcast explores how technology has changed sleep through the ages, specifically through artificial light.

Hear historian Roger Ekirch and psychiatrist Thomas Wehr explain how they each discovered the natural segmented sleep pattern our bodies want. And why we don't sleep that way because of modern technology.

Plus, we learn what actually happens to our brains when someone actually does return to the ancient way of sleeping: "People would sometimes say they felt a kind of crystal clear consciousness when they were awake that was not familiar to them. And it made me wonder if any of us knows what it’s really like to be awake — fully awake,” Wehr says.  

Even though technology is the problem, it can also be the solution. "You have people that are using their phones as alarm clocks, people who are checking their phones all night long... And every time you get that hit of light, it’s like a hit of espresso, and we’d like to fix that for everybody,” says Lorna Herf, co-creator of the app f.lux. She and her husband have an app and a plan.

The revelations in this episode might be a wake-up call. You’ll sleep better after listening to this one.
