For a year of my life, I cheated sleep. Here’s how.

For a year of my life, I cheated sleep. Looking for extra hours in the day, I decided to try something called “polyphasic sleep,” where I slept for a smaller chunk at night, and supplemented that with naps through the day. On that schedule, I was able to cut my sleep from 8 hours to 4.5 hours. Watch the video above to see how I did it.
