Kind of related, but there is a concept of polyphasic sleep - where you sleep for small increments throughout the day (like 30 minutes every 3 hours). I did it for a bit at a startup thinking we were "hacking sleep" and "getting more productive hours out of every day!" - It takes awhile to transition to it, but once there, your scheduled "sleeps" are insane, 15 minutes, feel like straight to REM. The main problem was if you missed on schedule sleep you were a zombie.

However, it is very, very fragile to any kind of interruption, so they stopped looking into it.
