DC1 is a [[Scheduling|schedule]] which logically follows [[Segmented|Segmented sleep]], shortening its [[Cores|core]] (usually the second one) and adding a [[Naps|nap]] to compensate for the lost REM.

Dual Core 1, or DC1, is a schedule which logically follows [[Segmented|Segmented sleep]], and it is the first Dual Core schedule, with the reduction of some sleep from the second core of Segmented and the addition of one daytime nap to compensate for the reduced amount of REM in the second core. This allows for some sleep reduction on the schedule, and polyphasic sleepers will now officially be able to learn to nap, as Segmented sleep does not have any naps.

=== Extended sleep cycles ===

This option has only 2 sleep cycles, for example 1.5h+1.5h or 2h+2h. Is much harder and recommended only for those with lower sleep needs, 6h mono or less. It allows for much less LNREM/REM.
