Hello everyone, This poll is set up to collect your opinions on what you think of an ideal nap length in polyphasic sleep. Please note the following things before you vote: 1. If you fall asleep in 3 minutes, or 2 minutes, and your nap length totals 25 minutes for example, then your nap length is not exactly 20 minutes! 2. Nap length is only maximum of 90 minutes long and not to be confused with a core sleep. If you look up nap lengths, no source says that we should nap for more than 90 minutes, hence the conclusion of maximum length. Furthermore, please be aware that a core sleep is also at least 90 minutes, and if you are, or have adapted to some schedule(s) that have 90-min sleep(s) and 20-min sleep(s) for example, you can consider the 90-min sleep(s) naps as well, because, the "core" sleep(s) is/are technically naps as well. 3. This poll is to assume that you have tried one, or multiple choices in the poll for some amount of time (at least 1 month). If you don't feel okay, or fail in adaptation, please comment below about what happened, and what you tried to do, etc... Please be creative! It has been of great interest for me to actually be able to effectively answer new polyphasers' questions about this topic, as well as being able to adapt to, or come up with something very efficient. Please note that multiple choices are allowed, and totally possible. If you want to comment, please feel free to! Thank you very much for reading, and participating in the poll!
