I will tell you the received wisdom from my friends' experience, and their friends' experience with polyphasic sleep: It is in theory doable, but often in practice a disaster because you end up getting less sleep than the minimal theoretical requirements given by polyphasic sleep.
If on polyphasic sleep you are sufficiently undisciplined that you end up racking up 40 hours of sleep debt, this wisdom would say you should probably stop doing polyphasic sleep. And instead of biohacking your way out, just have a few nights of normal sleep.
I have at least 40 hours of sleep debt from a polyphasic sleep schedule and attending hackathons. This number is a conservative estimate. Has anyone here researched the neurobiology of sleep deprivation? What can I do to recover quickly?
