Naptation
From Polyphasic Sleep Wiki
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.
