 A survey by Sleep Junkie found that 55% of people who use podcasts to fall asleep doze off within 15 minutes. These podcasts work because they use soothing voices and also boring content that keeps your brain from getting engaged. Here are a few that people swear by. The I Can't Sleep podcast is hosted by Benjamin Boster. He reads boring Wikipedia articles in this deep, monotone voice. People say it's life-changing. Next one, SleepJunkie.
