I thought this might be useful for some productivity junkies like me
In short, naps are more efficient way to sleep . If you take more naps throughout the day, you won't need to take as much sleep overall. It is hard to adapt during the first two weeks but once you adapt and stay on pattern you won't feel tired and shouldn't have any health issues.
Long term benefits/risks are uknown
Everyman sleep pattern = you take one core sleep and 1-5 naps throughout the day
Uberman pattern = 20-30 minute naps every 4 hours. 3 hours of sleep per day is quite realistic. Getting used to it is the hardest part, only like 1% people pass the adaptation period. Once again, you shouldn't feel tired once you get used to and stay on strict schedule
What is your excuse of not benefiting from this right now?
