Most people sleep using a Monophasic circadian rhythm sleep schedule, where they go to sleep in the late evening and wake up in the morning, which results in about 8 hours of sleep and 16 hours of being awake.
Uberman has developed a new Polyphasic circadian rhythm sleep schedule, where you take a power nap of 30 minutes every 4 hours. The goal of the sleep cycle is that you are actively in REM sleep within a couple of minutes of falling asleep and remain in that state until you awaken.
This method of organizing optimizes your sleeping time to maximize your REM sleep and minimize your non-REM sleep, so that you power naps are really effective. The result is that you sleep for only 3 hours each day, so that you are awake for 21 hours.
So, now I'm wondering about the productivity result of being more hours awake because of less sleep which isn't necessarily bad. When searching for Uberman's Sleep Schedule in combination with Productivity online I don't find any interesting results, but when looking for Polyphasic Productivity I mostly get tips that show that polyphasic sleep gives a boost in productivity. Here is such example, indicating that it did help!
Now my question is... Does Uberman's Sleep Schedule result in more productivity?
