Naptation
Naptation is an extreme method to prepare to a polyphasic adaptation, which involves taking frequent naps throughout the day. The goal is to get used to napping and/or getting SOREM in naps.
Mechanism
A standard Naptation lasts several days as a preparation to a goal schedule. This is a nap-only schedule, which technically is a variant of Uberman with 12 naps. However, adaptation isn't the goal, which distinguishes Naptation from other sleep schedules.
For those, who have difficulties with falling asleep in naps, it's common to stay awake for 24-36 hours before starting Naptation, although this step isn't required, since low total sleep time eventually makes it easier to fall asleep.
Intense sleep pressure is supposed to lead to REM or SWS rebound after a few days, which makes naps quality better. This is when the result of Naptation can be considered successful and switching to a goal schedule happens.
Methods
Naptation can be applied differently depending on the goal and final schedule.
With recovery
This method is often used before schedules with a high total sleep time, when the goal is to learn to nap. Once naps start to work better, the sleeper switches to recovery for recovering intense sleep debt after Naptation. It's often recommended to start polyphasic adaptation without prior sleep deprivation, which helps to keep adaptation much milder, with a shorter Stage 3.
